Such LCD mainly is divided in the above the display panels of display image and the driver element that drive signal is provided for display panels, display panels comprises first and second glass substrates that bond together, between substrate, have predetermined gap, and be injected into a liquid crystal layer between first and second glass substrates.

Specifically exactly first and second glass substrates are bonded together, provide predetermined gap betwixt, then liquid crystal (below write a Chinese character in simplified form into LC) is injected this gap with a wadding.

Inject liquid crystal in the mode of keeping vacuum state between two substrates in this case, a LCD ejection inlet is immersed liquid crystal solution, utilize osmotic pressure that liquid crystal is injected this gap.After finishing the liquid crystal injection, use sealant encapsulated liquid crystals injection inlet.

But, make LCD with this common liquid crystal injecting method and have following shortcoming or problem.

At first, liquid crystal injects the overlong time that needs can reduce output, could inject liquid crystal because will keep vacuum between two substrates.

The second, when making the large scale liquid crystal display, this liquid crystal injecting method can not be full of the inside of panel fully with liquid crystal, thereby can cause fault.

Finish according to various patterns TFT and color filter array handle (S1, S2) afterwards, before forming alignment on each substrate, to carry out cleaning treatment (S2, S7).And distinguish carry out in the above alignment and friction treatment (S1-S3, S6-S8).

(S4 S9) removes the particulate that produces in aligning and the friction treatment to carry out cleaning treatment then.

Below to explain the cell processing (S10) that is used on color filter array substrate, printing silver point and sealant.

At first, do not have in the drawings under the situation of TN pattern of expression, after second substrate, 20 peripheries have formed silver (silver) point, first and

second substrates

10 and 20 are bonded to together, the common electrode 23 on second substrate 20 is applied a voltage.

On the other hand, IPS (in-plane switching) mode LCD does not need to form silver point, because common electrode and pixel electrode are formed on first substrate, can induce a transverse electric field.

Figure 25 represents to form according to a kind of sealant of one embodiment of the invention the layout of step.

On the edge of each panel on second substrate 20 of similar closed figures, form many places master UV curing sealant 30, and on a peripheral virtual area of the main UV curing sealant 30 of similar closed figures, form the first virtual UV curing sealant 40 everywhere.And on each angle of first virtual UV curing sealant 40 external zoness the coating the second virtual UV curing sealant 50.

In the drawings, second virtual UV curing sealant 50 similar ' ' figures that the external zones place of both sides forms on 40 jiaos of the first virtual UV curing sealants.Also can form the second virtual UV curing sealant 50 of similar straight line at the external zones of each angle one side of the first virtual UV curing sealant 40, or form closed figures at the external zones of the first virtual UV curing sealant 40.

When sealant, can adopt methods such as serigraphy and distribution method.When silk screen touches substrate, the alignment on the method for printing screen possibility wounded substrate.In addition, if substrate area is very big, method for printing screen can cause very big waste.Therefore, preferably adopt distribution method in this case.

The monomer or the oligomer that preferably two ends are adhered to acrylic mix back with UV curing sealant 30 and the first and second virtual

UV curing sealants

40 and 50 of deciding with a kind of initiating agent.Or be adhered to acrylic and the other end is adhered to the monomer of epoxy radicals or oligomer and mixes the back with a kind of initiating agent with UV curing sealant 30 and the first and second virtual

UV curing sealants

40 and 50 of deciding with an end.If adopt two ends to be adhered to acrylic and monomer that mixes with initiating agent or oligomer, just make sealant cures with the UV ray.On the other hand, the other end is adhered to epoxy radicals and monomer that mixes with initiating agent or oligomer if adopt an end to be adhered to acrylic, just makes sealant cures with UV ray and heating.

Below to explain the method that forms main UV curing sealant in detail.

Figure 26 A and 26B represent to form according to first embodiment of the invention a kind of detailed schematic of main UV-curing type sealant, and Figure 27 represents to form according to second embodiment of the invention a kind of detailed schematic of main UV-curing type sealant.

Shown in Figure 26 A and 26B,, on second substrate 20 that is similar to the figure that does not have injection port, form main UV curing sealant 30 with distributor 31 because the liquid crystal drop adding method does not need to inject the injection orifice of liquid crystal.

Yet the viscosity of main UV curing sealant 30 is very high, can be flocked on the nozzle tip of distributor 31.Coalescent sealant causes on starting point (being ' A ' district among Figure 26 B) sealant dispensed too much.

Shown in Figure 26 B, the main UV curing sealant of crossing overabsorption can be in the diffusion of the both sides of the virtual area (substrate peripheral) in active area (substrate center's part) and the follow-up adhesion step, the sealant that is diffused into active area can pollute liquid crystal, and all the other sealants that are diffused into virtual area can infiltrate the unit line of cut and bring difficulty for the unit cutting step.

For the ease of the unit cutting step and avoid liquid crystal in adhesion step, to be polluted, need to form the uniform more main UV curing sealant of density, print main UV curing sealant by the following method.

Referring to Figure 27, after each panel edges of second substrate 20 locates to form an auxiliary UV curing sealant 30a along (virtual area), form a main UV curing sealant 30 with distribution method successively, form a closed figures that does not have injection port.

The effect of auxiliary UV curing sealant 30a is to prevent that thereby the tip that is flocked on the distributor nozzle because of sealant from forming an adverse effect that cause the optional position in the virtual area of substrate.And as long as it is just enough to form auxiliary UV curing sealant 30a before main UV curing sealant 30.Also can form the auxiliary UV curing sealant 30a of straight line or curve shape in addition.

So just finish silver point and sealant and formed step (S10).

Be coated with second substrate 20 of sealant above then in supersonic wave cleaning machine (USC), cleaning, remove the particulate (S11) that produces in each step.Also do not drip liquid crystal above just cleaning but formed second glass substrate 13 of sealant.

At first substrate 10 that drips liquid crystal with formed in second substrate 20 of

sealant

30,40 and 50, drip the position that liquid crystal is arranged and be coated with sealant other positions front end face up.For first substrate 10 that dropping is had liquid crystal and second substrate 20 that has formed

sealant

30,40 and 50 are bonded to together, need be with a

substrate

10 or 20 upsets.Yet, dropping can not be had that substrate overturn of liquid crystal.Therefore will overturn and form second substrate 20 of sealant, make the position that forms

sealant

30,40 and 50 face down (S12).

Do not take a kind of method second substrate to be loaded into the table top of a negater that is used for aiming in advance under this upset situation of expression in the drawings, second substrate is clamped on the table top, with table top rotation upset, and second substrate 20 that will overturn is sent into a vacuum bonding chamber.

To explain that below liquid crystal drips step.

Figure 28 represents according to a kind of distributor of the present invention, a sectional view when representing not drip LC as yet comprising Figure 28 A, and a sectional view when Figure 28 B represents to drip LC, and Figure 28 C represents the detailed schematic of disintegrating.

As shown in the figure, in distributor 120, a cylindrical shape liquid crystal container 124 is received in the shell 122.Liquid crystal container 124 usefulness tygon are made, and liquid crystal 26 is equipped with in inside.Shell 122 usefulness stainless steels are made, and receive liquid crystal container 124 in inside.Tygon has good forming characteristic usually, can form the shell with ideal form, and can not react with the liquid crystal that charges into container, thereby can be used as liquid crystal container 124.Yet poly intensity fragility is subjected to outside faint impact with regard to easy deformation.Specifically, liquid crystal container 124 easy deformation made from tygon can't drip liquid crystal 26 in accurate position, therefore are received in the shell that stainless steel makes.An air supply pipe 164 is formed at the top at liquid crystal container 124, is connected to outside air supply unit 162.By air supply pipe 164 from outside air supply unit 162 the supply of nitrogen.Like this, can not will be filled by nitrogen by the zone that liquid crystal is full of, liquid crystal is exerted pressure drips liquid crystal.

Form an opening 123 in shell 122 lower ends.When liquid crystal container 124 was received in the shell 122, the projection 138 that is formed on liquid crystal container 124 lower ends was inserted into opening 123, and liquid crystal container 124 is connected to shell 122.In addition, projection 138 is also connected to first linkage unit 141.A nut is arranged, and a side of first linkage unit 141 there is a screw on projection 138.So just can with screw projection 138 be connected together with first linkage unit 141 with nut.

The other end at first linkage unit 141 forms a nut, and forms a screw at an end of second linkage unit 142.So just first and second linkage units 141 can be connected together with 142.In this case, a faller gill 143 is placed between first and second linkage units 141 and 142.When the screw of second linkage unit 142 was inserted into the nut of first linkage unit 141, faller gill 143 was connected between first and second linkage units 141 and 142.In faller gill 143, form a discharge orifice 144, be full of the liquid crystal of liquid crystal container 124 by second linkage unit 142 and discharge orifice 144 dischargings.

A nozzle 145 is connected to second linkage unit 142.Nozzle 145 is used to drip a small amount of liquid crystal 126 that charges into liquid crystal container 124; and the support portion 147 that comprises a band screw; screw is connected to the nut of second linkage unit, 142 1 ends; be connected to nozzle 145 by second linkage unit 142; discharge portion 146 is 147 outstanding from the support portion; on substrate, distribute a spot of liquid crystal, and 147 outsides form a protective bulkhead 148 that is used for protecting discharge portion 146 in the support portion.

Delivery pipe that stretches out from the discharge orifice 144 of faller gill 143 of 147 inboard formation is connected to discharge portion 146 in the support portion.The discharge portion of nozzle 145 has very little diameter (for meticulous control liquid crystal discharge capacity) usually and is 147 outstanding from the support portion.

Therefore, the discharge portion 146 of minor diameter is subjected to operating the influence of external force easily, for example is on second linkage unit 142 during assemble/disassemble nozzle 145.For example, if discharge portion 146 deforms when nozzle 145 is connected on second linkage unit 142 or breaks, the diameter of discharge portion 146 will change, the uncontrollable amount of liquid crystal that is assigned on the substrate.In addition, liquid crystal can be splashed to burst region and finally drop on wrong position.If the liquid crystal that distributes is splashed to sealing area (sealed dose cover and top and first substrate bonding are arrived together zone) because discharge portion 146 is broken, will expand in the zone that splashes liquid crystal on the sealant, form a trouble spot in panel of LCD.

The protective bulkhead 148 of discharge portion 146 can prevent that the discharge portion 146 of nozzle 145 from breaking because of above-mentioned external force.As shown in FIG., at wall of discharge portion 146 peripheral formation, prevent that external force is applied on the discharge portion 146 with predetermined altitude.

The enlarged drawing of local ' A ' among Figure 29 presentation graphs 28A, Figure 29 A wherein represents detail view, and Figure 29 B represents sectional view.Protective bulkhead 148 is that the periphery around the discharge portion 146 of nozzle 145 forms, and is almost contour with discharge portion 146, and brake specific exhaust emission portion 146 height preferably prevent to cause nozzle 145 distortion or break such as instruments such as fastening means when assembling or dismounting nozzle 145.

In addition, the overall dimensions of nozzle 145 increases because of protective bulkhead 148.Because jet size is all very little usually, be difficult to instrument assemble/disassemble nozzle 145 on second linkage unit 142.Yet the present invention just can facilitate for the assemble/disassemble of nozzle 145 like this by the size that formation protective bulkhead 148 has increased nozzle 145.

Can form protective bulkhead 148 with any material that can protect discharge portion 146 to avoid external force, for example can use stainless steel, hard metal alloy or have the material of sufficient intensity.

Referring to Figure 29 B, for example be fluororesin 149 around a kind of material that liquid crystal is had a high contact angle of the periphery coating of the discharge portion 146 of nozzle 145, its purposes is as described below.

Contact angle is meant the angle that liquid forms when reaching thermodynamic equilibrium on solid surface.This contact angle is a kind of mark of indication solid surface wettability.Nozzle 145 is with generally having the metal of low contact angle.Because metal has high wettability (water wettability) and high surface energy, liquid crystal scatters on nozzle surface easily, drips (distribution) Shi Buhui at liquid crystal by metallic nozzle 145 and forms drop figure (this means the contact angle height) in discharge portion 146 ends of nozzle.Along with liquid crystal drips repeatedly, spreading to nozzle 145 lip-deep liquid crystal will be coalescent.

Liquid crystal spreads to nozzle 145 lip-deep phenomenons and makes and can not accurately drip liquid crystal.Control the amount of liquid crystal that discharges by the discharge portion 146 of nozzle 145 even impose on the pressure of liquid crystal by adjusting with the time of opening discharge orifice 144, the liquid crystal of discharging also can some spread on the nozzle surface.Therefore, the amount of liquid crystal of actual dropping on substrate is than lacking by discharge portion 146 dischargings.Can certainly control discharge capacity according to spreading to nozzle 145 lip-deep amount of liquid crystal.Yet be difficult to calculate and spread to nozzle 145 lip-deep amount of liquid crystal.

Can also add the coalescent amount of liquid crystal of liquid crystal dropping because of repeatedly in addition on the amount of liquid crystal of 146 dischargings of the discharge portion by nozzle 145, like this, the amount of liquid crystal that is added drop-wise on the substrate will surpass set amount.In other words, the amount of liquid crystal that drips according to the low contact angle of metallic character from the metallic nozzle is irregular.

On the other hand, if around nozzle 145, enclose the fluororesin layer 149 that particularly has high contact angle around discharge portion 146 coatings of nozzle, the liquid crystal 26 that discharges by the discharge portion 146 of nozzle 145 just can not spread on the surface of nozzle 145, but because the low wettability (water wettability) and the low-surface-energy of fluororesin layer 149 form desirable droplet-like.So just the amount of liquid crystal that can will accurately design drips on substrate.

Utilize dipping or spray fluororesin layer (being Teflon) is coated on the surface of nozzle 145.In Figure 29 B, only around discharge portion 146, applied fluororesin layer 149.Yet also coating fluororesin layer 149 on whole nozzle 145 surfaces of protective bulkhead 148 can comprised.Fluororesin has wear-resistant, and is heat-resisting, and anti-chemical or the like characteristic, and have high contact angle so just can prevent more effectively that nozzle 145 from breaking because of external force or be out of shape.

A pin 135 is inserted liquid crystal container 124, make a termination of pin 135 contact faller gill 143.That end that pin 135 touches faller gill 143 has cone shape, can insert the discharge orifice 144 of faller gill 143 and blocks discharge orifice 144.Pin 135 comprises independent first and second pins 136 and 137.As shown in Figure 29, a conical termination contacts faller gill 143 and projection 136a of other end formation on first pin 136.End at second pin 137 forms a groove 137a in addition, and the projection 136a of first pin 136 is inserted into wherein.

The groove 137a that the projection 136a of first pin 136 is inserted into second pin 137 is fixing with a stationary installation 139 then, and first and second pins 136 are connected together with 137.Stationary installation 139 is made of metal, and a part open ring is arranged.Because annular inner periphery is less than the diameter of first and

second pins

136 and 137, first and

second pins

136 and 137 coupling part are inserted into inboard and its flexible fastening of ring.Can form groove and projection respectively on first and

second pins

136 and 137 in this case, the groove that the projection of second pin 137 is inserted first pin 136 is fixing with stationary installation 139.

The reason that forms pin 135 separately is as follows.One termination of pin 135 contacts faller gill 143, and to open or close discharge orifice 144, pin 135 plays important effect in the process that drips liquid crystal on substrate.And pin 135 is that one constitutes.That is to say that if one of pin 135 and faller gill 143 need because of breaking to change, pin 135 and faller gill 143 just all need to change.Simultaneously, pin 135 periodically upwards moves down, and liquid crystal drop is added on the substrate.This periodic motion meeting forms continuous impact to pin 135.In addition, compare with the length of pin 135, the diameter of pin 135 is very little.Therefore, pin 135 breaks or the possibility of being out of shape can increase.Pin 135 break or distortion can form the gap, when the conical end of pin 135 is inserted into discharge orifice, can't block discharge orifice 144.Liquid crystal can be added drop-wise on the substrate by this gap.Therefore, pin 135 necessary replacings of breaking or being out of shape.Yet the pin 135 of the costliness that single-piece constitutes and faller gill 143 need to change simultaneously.

On the other hand, according to the present invention, if pin 135 comprises independent first and

second pins

136 and 137, iff changing the pin that must or break, just can cost saving.In addition, if second pin 137 distortion or break wants to change pin 135 at the bottom of the Beecher and faller gill 143 can be saved more expense, this is because of need not changing first pin 136 and faller gill 143, but can only change second pin 137.

In the drawings, forming on first and

second pins

136 and 137 respectively can projection 136a connected to one another and groove 137a, and fixes with stationary installation 139.The present invention also is not limited only to this special construction, and this only is an example for explaining that the present invention provides.Pin of the present invention in addition can connect in various manners.For example, can be only just first and second pins 136 can be connected together with 137 with groove, not need stationary installation, or screw and nut is set at first and second pins 136 on 137 respectively they are connected together or the like by connecting projection.

In addition, be contained in and load one first spring 128 on the other end of the pin 135 on distributor 120 upper casings.First spring 128 is received in the cylindrical shape first spring receiving element 150.Shown in Figure 28 C, on a support portion 121 of liquid crystal container 124 tops formation, form a screw 125, support liquid crystal containers 124 with respect to shell 122, and on the first spring receiving element 150, form a nut.So just the first spring receiving element 150 can be fixed on the support portion 121.The opening that not concrete in the drawings of representing is provided with nut is set at the top of the first spring receiving element 150, and inserts the pulling force that a pulling force control module 152 is controlled first spring 128 by opening.Because screw 153 is set at pulling force control module 152, the length that the screw 153 of pulling force control module 152 inserts in the first spring receiving element 150 can be regulated.Pulling force control module 152 be inserted in the first spring receiving element 150 an end just an end of screw 153 can touch first spring 128.So just first spring 128 can be fixed between the stationary installation 139 and screw 153 of pin 136.

Use numeral ' 154 ' representative to be used for fixing the fixed head of pulling force control module 152 in the drawings.Shown in Figure 28 A, if fixed head 154 is not closely to be attached on the first spring receiving element 150, pulling force control module 152 just can rotate, thereby can regulate pulling force.Yet shown in Figure 28 B, if fixed head 154 closely is attached on the first spring receiving element 150, pulling force control module 152 just has been fixed, thereby is arranged on a corresponding pulling force.

As mentioned above, the pulling force of first spring 128 can be set, because first spring 128 is fixedly installed between stationary installation 139 and the pulling force control module 152 with the length of inserting the pulling force control module 152 in the first spring receiving element 150.For example, if operation pulling force control module 152 shortens the length (screw 153 length outstanding from the first spring receiving element, 150 tops just) that is inserted into the screw 153 in the first spring receiving element 150, the length of first spring 128 will prolong, and pulling force reduces.If the contraction in length of screw 153, pulling force just increases.So just can effectively control the pulling force of first spring 128 by operation pulling force control module 152.

A bar magnet 132 is loaded on top at pin 135, makes itself and pin 135 at a distance of an interval x.And second spring 131 is installed on bar magnet 132.As shown in the figure, second spring 131 is received in the second spring receiving element 135 that is fixed on the upper casing 126, and will make it move in the bar magnet 132 insertions second spring receiving element 135.Like this, the elastic force of second spring 131 just can be applied on the bar magnet 132.

Ferromagnetic or the soft magnetic material of bar magnet 132 usefulness is made, and a cylindrical shape solenoid 130 is installed in the second spring receiving element, 135 outsides.Solenoid 130 is connected to power supply unit 160 and is its power supply.When obtaining power supply, produce magnetic force by bar magnet 132.Pin 135 touches bar magnet 132 under magneticaction.If cut off the electricity supply, pin 135 just returns its original position under the elastic force effect of first spring 128 that is installed to pin 135 1 ends.So just can open or close the discharge orifice 144 that on faller gill 143, forms by moving up and down of pin 135.

The control that moves up and down of pin 135 just is installed in the influence of second spring 131 on the bar magnet 132 to the control of discharge orifice 144 opening/closing required times.As long as for solenoid 130 power supplies produce magnetic force by bar magnet 132, pin 135 is just upwards carried, touch bar magnet 132 and also upwards push away, bar magnet 132 is upwards carried, the pressure of the bar magnet 132 that second spring 137 is moved up at once.If bar magnet 132 loses magnetic force because of the power supply of supplying with solenoid is cut off, the elastic force of second spring 137 of compression just is applied on the bar magnet 132, promotes pin 135 downwards with bar magnet 132.

So just can pin 135 be descended fast, thereby effectively control the dropping of liquid crystal with first and second springs 128 and 131.Move pin 135 with first and

second springs

128 and 131 and can prevent effectively that the friction between first pin 136 and the liquid crystal from causing the dropping fault, as mentioned below.

The viscosity of liquid crystal is generally much higher than liquid.Therefore, when pin 135 was mobile in liquid crystal, the mobile meeting of pin 135 was slow because of friction between the surface of pin 135 and the liquid crystal.Calculate the opening the time of discharge orifice 144 of faller gill 143 as variable if when dripping liquid crystal, adding the mobile delay of the pin 135 that friction causes, just can accurately calculate the time of opening.Yet the amount of liquid crystal of filling in the liquid crystal container 124 can and reduce along with the liquid crystal dropping, and also can shorten the time delay of pin 135.Therefore just be difficult to carry out accurate liquid crystal drop dosage, because the time of opening of discharge orifice 144 also can shorten.

Yet, if according to the present invention with the moving of two

springs

128 and 131 control pins 135, the decline rate of pin 135 can be very fast, and the surface of pin 135 and the friction between the liquid crystal are irrelevant.Therefore just can keep discharge orifice 144 has uniformly and opens the time, so just can the dropping of accurate quantification ground execution liquid crystal.

Ferromagnetic or the soft magnetic material of bar magnet 132 usefulness is made, and a cylindrical shape solenoid 130 is installed in the second spring receiving element, 135 outsides.Solenoid 130 is connected to power supply unit 160 and is its power supply.When obtaining power supply, produce magnetic force by bar magnet 132.Pin 135 touches bar magnet 132 under magneticaction.If cut off the electricity supply, pin 135 just returns its original position being respectively installed under first and second springs 128 on pin 135 and the

bar magnet

132 and 131 the elastic force effect.So just can open or close the discharge orifice 144 that on faller gill 143, forms by moving up and down of pin 135.

The end of first pin 136 touches faller gill 143 repeatedly along with the power supply on/off that imposes on solenoid 130.So just might break, because the end of first pin 136 directly is exposed to continuous impact with faller gill 143 because of contacting repeatedly.For example be end and the faller gill 143 that hard metal is made first pin 136 preferably, in order to avoid break because of impact causes with high impact material.

Referring to Figure 28 B, along with the discharge orifice 144 of faller gill 143 is opened, the gas (nitrogen just) that offers liquid crystal container 124 is exerted pressure to liquid crystal, drips liquid crystal 26 from nozzle 145.In this case, the time that the amount of liquid crystal that drips is opened according to discharge orifice 144 changes with imposing on the pressure of liquid crystal, and the time of opening is depended on the interval x between pin 135 and the bar magnet 132, the magnetic force of the bar magnet 132 that produces by solenoid 130, and be installed in first and second springs 128 on pin 135 and the

bar magnet

132 and 131 pulling force respectively.Can regulate the magnetic force of bar magnet 132 according to the number of turn that is installed in the solenoid 130 around the bar magnet 132 or the watt level that offers solenoid 130, and can come the interval x between metering needle 135 and the bar magnet 132 by a gap control unit 134 that is installed in bar magnet 132 ends.

Regulate the pulling force of first spring 128 in addition with pulling force control module 152.Regulate the length that the wait of first spring 128 that is set at length-specific is revised with pulling force control module 152 if desired, the length difference that pulling force can be revised along with correspondence and changing so just can change the return speed of pin 135.Thereby just can control the opening the time of discharge orifice 144 of faller gill 143.So just can arbitrarily control the pulling force of first spring 128 with pulling force control module 152, on substrate, drip quantitative liquid crystal.So just can arbitrarily control the pulling force of first spring 128 by the mode of user's direct control pulling force control module 152.

In addition, the user also can be provided with the interval x between metering needle 135 and the bar magnet 132.In other words, the user can opening the time with the discharge orifice 144 of interval z and

spring

128 and 131 regulated at will faller gills 143.

On the other hand, the nitrogen amount that offers the watt level of solenoid 130 and supply with liquid crystal container 124 is by control power supply unit 160 and is installed on the air supply pipe 164 that is connected to air supply unit 162 to the main control unit 170 of the flowrate control valve 161 of liquid crystal container 124 supply gas and determines.In other words, watt level and gas flow are not controlled by user's direct control, but are controlled by main control unit 170, and this unit comes rated output size and gas flow according to the input data.

As shown in figure 30, main control unit 170 comprises the input block 171 of importing various information, drip the dripping quantity computing unit 173 of the liquid crystal drop dosage on whole base plate according to input data computation needs, the liquid crystal drop dosage of calculating according to dripping quantity computing unit 173 calculates the distribution figure computing unit 175 that liquid crystal distributes figure, come the substrate drive unit 176 of driving substrate according to the distribution figure that distributes figure computing unit 175 to calculate, the power control unit 177 of control power supply unit 160, provide power supply with the liquid crystal drop dosage of corresponding needs dropping for solenoid 130 according to the distribution figure that distributes figure computing unit 175 to calculate, the flow controlling unit 178 of Control Flow operation valve 161, it is liquid crystal container 124 air feed according to the distribution figure that distributes figure computing unit 175 to calculate from air supply unit 162, the air demand correspondence the dripping quantity of the liquid crystal that needs dropping, and an output unit 179, the data of its output input, the dripping quantity of calculating, the distribution figure that calculates, current state that liquid crystal drips or the like.

As shown in figure 31, input block 171 comprises the wadding height input block 180 that is used for importing the wadding height that forms on substrate, the information that is used for importing relevant liquid crystal is the liquid crystal characteristic information input unit 182 of viscosity for example, and the information substrate input block 184 that is used for importing the various information that needs the panel of LCD size of making and relevant substrate.

Even the liquid crystal drop dosage that sets during the actual height that forms the cylindrical liner material on filter substrate is different with the box gap of setting, when liquid crystal drop was added on the substrate, the amount of liquid crystal of filling the panel of LCD of practical set also can be different with the amount of liquid crystal of the best (because box gap can because the height of the cylindrical liner material of actual formation produce a difference).For example, if the dripping quantity of the liquid crystal of actual dropping is littler than best dripping quantity, normally will go wrong, or normally can go wrong for the white brightness in the LCD of white mode for the black brightness in the LCD of black mode.

In addition, if the dripping quantity of the actual liquid crystal that drips is bigger than best dripping quantity, when the assembling panel of LCD, will cause the gravity fault.The gravity fault is to cause because of the volume at the inner liquid crystal layer that forms of panel of LCD increases with temperature, and the box gap of panel of LCD can increase, and liquid crystal is moved down because of gravity.Like this, the box gap of panel of LCD will become irregular, and the quality of LCD is descended.

In order to overcome this problem, main control unit 170 is by compensating the liquid crystal drop dosage of dropping on substrate at the cylindrical liner material height that forms on the substrate, and will calculate the dripping quantity of liquid crystal.In other words, current liquid crystal drop dosage of calculating is compared with the dripping quantity of calculating according to the wadding height, adding or deduct therewith then, the corresponding amount of liquid crystal of difference is exactly the amount of liquid crystal that drips on substrate.

Wadding at TFT forms input wadding height in step or the color filter step.Specifically, form measurement wadding height in the step, send dripping quantity computing unit 173 to by wadding height input block 180, and form wadding at wadding.It is what to separate with the liquid crystal drop ledger line that wadding forms line.So just can the wadding height that record be input to wadding height input block 180 by wired or wireless mode.

Liquid crystal characteristic information input unit 182 or information substrate input block 184 pass through such as keyboard, mouse, normal operations devices such as touch-screen input data, the size that the panel of LCD that needs making is for example arranged by user's input substrate information, substrate size, the panel quantity that on substrate, forms, and liquid crystal characteristic information.Output unit 179 provides various information for the user, and comprises such as various output units such as displays, comprises CRT (cathode-ray tube (CRT)), LCD and printer.

Dripping quantity computing unit 173 calculates total dripping quantity that will drip the liquid crystal on whole base plate, on whole base plate, to form a plurality of liquid display panel panels, and calculate the dripping quantity that will drip the liquid crystal on panel of LCD, and the dripping quantity of calculating is offered distribution figure computing unit 175.

Shown in figure 32, distribute figure computing unit 175 to comprise dripping quantity computing unit 186 one time, the dripping quantity that it calculates according to dripping quantity computing unit 173 is calculated a dripping quantity of the liquid crystal of dropping ad-hoc location on substrate, one drips number of times computing unit 187, be used for calculating the dropping number of times that will drip on substrate, one drips position calculation unit 188, the position that dripping quantity that its basis is calculated in a dripping quantity computing unit 186 and the dropping number of times that drips calculating in the number of times computing unit 187 calculate the liquid crystal of dropping on substrate, and a distribution figure determining unit 189, it determines the distribution figure of liquid crystal according to the dropping position of calculating.

A dripping quantity computing unit 186 calculates a dripping quantity of liquid crystal according to total dripping quantity of calculating.In other words, a dripping quantity has relation closely with total dripping quantity and dropping number of times.

Drip the total dripping quantity of number of times computing unit 187 according to input, the area of panel, and the characteristic of liquid crystal and substrate is calculated and will be added drop-wise to a dropping number of times on the panel.According to the dropping method of routine, drip at the liquid crystal on the substrate and on substrate, scatter because of upper and lower substrate is bonded to the pressure that a time-out is applied on it.The distribution of liquid crystal depends on such as liquid crystal characteristic such as the viscosity of liquid crystal and will drip the structure of the substrate of liquid crystal in the above, for example is the layout of figure or deployment or the like.So just can determine the once area that liquid crystal scattered of dropping with above-mentioned characteristic.Will calculate the dropping number of times that will drip the liquid crystal on a panel for this reason.Also to calculate the number of times that will drip on whole base plate in addition according to the dropping number of times of panel.

Drip position calculation unit 188 according to the dropping number of times on the panel, the dripping quantity of the liquid crystal of Di Jiaing once, the spacing between the liquid crystal droplet of dropping, and the dispersion characteristic of liquid crystal calculates the dropping position of liquid crystal.Specifically, the dispersion characteristic of liquid crystal is to judging that the sealant that can liquid crystal reach on the bonding substrate is important.Therefore, before sealant cures, just touch sealant, drip position calculation unit 188 and will consider that the dispersion characteristic of liquid crystal calculates the dropping position in order to prevent liquid crystal.The general factor of determining the dispersion characteristic of liquid crystal comprises panel-shaped, the component graphics that forms on panel, and the frictional direction of the alignment of panel (aligning direction).Drip position calculation unit 188 and consider that like this these factors calculate the dropping position of liquid crystal.

Simultaneously, the dropping position of liquid crystal is a more importantly factor to the critical failure or the degeneration of liquid crystal panel.In the LCD panel manufacturing method that adopts liquid crystal to drip, provide on upper and lower substrate, drip liquid crystal in advance and with upper and lower substrate bonding to together, thereby the liquid crystal of dropping is distributed to form on the whole base plate liquid crystal layer.In this case, the bonding of upper and lower substrate finished by making sealant cures after the liquid crystal layer distribution.Yet, when the liquid crystal (just before sealant cures) in bonding process that drips can touch sealant when spreading between the substrate, and encapsulant ruptures can cause liquid crystal panel critical failure or degeneration.There is the liquid crystal panel of critical failure or degeneration to be dropped.In addition, if sealant does not break, particulate that contains in the sealant or impurity also can flow into liquid crystal.Liquid crystal be will pollute like this, inferior or defective liquid crystal panel produced.

The actual error that drips between position and the design dropping position might produce this poor quality or defective, and it mainly produces because of dripping positional fault.In other words, poor quality or defective are that cause the dropping position of erroneous calculations.

The calculating that liquid crystal drips the position relates to the liquid crystal dropping number of times of dropping on panel, a dripping quantity of liquid crystal, the spacing between the liquid crystal droplet that is distributed, and the dispersion characteristic of liquid crystal.Specifically, the dispersion characteristic of liquid crystal is bonded to a time-out liquid crystal by substrate can reach sealant be important judging.Therefore, before sealant cures, just touch sealant, consider that the dispersion characteristic of liquid crystal calculates the dropping position in order to prevent liquid crystal.

Yet, before sealant cures, just touch sealant in order to prevent liquid crystal, be arranged on one among a small circle if will be added drop-wise to the dropping area of the liquid crystal on the substrate, just liquid crystal just need be with on the whole surface that can be uniformly scattered onto substrate for a long time.Therefore, total manufacturing time of LCD will prolong.Otherwise if the scope that is provided with is excessive, liquid crystal will touch sealant and bring the problems referred to above before sealant cures.Therefore, when bringing the position, the calculating liquid crystal need aspect two, consider the deterioration of sealant and the speed of processing.

The present invention is provided with the dropping position of liquid crystal like this, allow be added drop-wise to liquid crystal on the substrate, and all the other areas (be on the substrate about 30% area) wait for that sealant is subjected to heat curing (being subjected to heat curing to accelerate to be added drop-wise to the distribution speed of the liquid crystal on the substrate by sealant) at the area that spreads on the whole base plate about 70% before the sealant cures.

The dispersion characteristic of liquid crystal is with relevant as the viscosity of liquid crystal inherent characteristic.Similar liquid crystal has identical viscosity number.Therefore, the determinative of liquid crystal dispersion characteristic with LCD of various sizes and pattern is the geometric properties of a substrate.

In general, the factor of decision liquid crystal dispersion characteristic has the shape of panel, the component graphics that forms on panel, and the frictional direction of the alignment of counter plate execution.The present invention consider these factors proposed a kind of on substrate the actual figure that drips liquid crystal, and a kind of liquid crystal drop adding method that adopts this figure.Below to further explain the present invention.

Figure 38 A represents the shape of liquid crystal panel to the synoptic diagram of 38C, can be used to explain the primary factor of determining the liquid crystal dispersion characteristic.Shown in Figure 38 A, when a circular liquid crystal 107 is dripped when a square liquid crystal panel is just on the infrabasal plate 105, have a difference apart from a with from the distance b of 107 to one jiaos in liquid crystal from liquid crystal 107 to one sides.Suppose that the distribution speed of liquid crystal on substrate 105 is isotropic, shown in Figure 38 B, liquid crystal 107 can arrive a side, can stay next distance b between liquid crystal 107 and angle '.Therefore, on 105 jiaos of substrates, can stay a zone that is not assigned to liquid crystal 107.

The present invention considers how to drip liquid crystal 107 on the substrate of this shape.The distribution figure 117 of liquid crystal 107 is shown in Figure 38 C.In this case, many blister liquid crystal that many liquid crystal 107 representatives of representing among the figure drip with the liquid crystal drop feeder apparatus.And distribute figure 117 are distribution patterns of the liquid crystal of dropping.

The liquid crystal of dropping on substrate distributes with the form of many blisters.Liquid crystal shown in Figure 38 A and the 38B extensively is distributed on the substrate 105, can be used to the dispersion characteristic of more popular and the liquid crystal that directly explain to drip.The actual liquid crystal 107 that drips on substrate 105 drips into many blisters by shown in Figure 38 C.

According to the present invention, liquid crystal distributes each corner of figure to have the scope of rectangle, distributes the spacing t1 and the t2 of figure 117 to be equal to each other in the x and y direction.By the reason of distributing figure 117 to drip liquid crystal be will be on whole bonding substrate (before the sealant cures) liquid crystal that on panel, distributes equably, if the distribution speed of liquid crystal is constant, just should stay uniform distance between the side of liquid crystal 107 that drips and substrate 105 and between the corner of liquid crystal 107 and substrate 105.

Distribute figure 117 to be not limited only to concrete shape, can revise according to the shape of substrate.For example, if substrate is a rectangle, the distribution figure that drips the liquid crystal on substrate is exactly the rectangular shape with angular region of extension, so that liquid crystal is the same with distance between the substrate peripheral (comprising side and corner).

Determine that it is the aligning direction of carrying out that liquid crystal distributes another factor of figure on alignment.Carry out to aim at generally is in order in one direction alignment to be applied alignment regulating force or surface orientation power makes adjacent liquid crystal molecule alignment.Aiming at mainly is to finish by the alignment that rubs in one direction with level and smooth fabric.Forming the little groove that is arranged on the specific direction (frictional direction) by friction on the alignment, liquid crystal molecule is alignd on specific direction.

Figure 38 D-38G represents to distribute the synoptic diagram of figure 117, is used for explaining the friction of alignment.If the direction of arrow in Figure 38 D is carried out friction, will on alignment, form groove along frictional direction.Shown in Figure 38 E, when liquid crystal 107 was dripped on substrate 105, the distribution speed of the liquid crystal of dropping on frictional direction can be accelerated.This is because liquid crystal can scatter by the groove that forms on frictional direction.Therefore, shown in Figure 38 F, when circular liquid crystal 107 was added dropwise on the substrate, the distribution velocity ratio of liquid crystal 107 on frictional direction was very fast, thereby can distribute according to a kind of elliptical shape with major axis.

Shown in Figure 38 G, consider the distribution speed of liquid crystal, the present invention drips liquid crystal according to the distribution figure 117 with elliptical shape.In this case, liquid crystal scatters speed frictional direction is parallel faster on the minor axis that distributes figure 117 and the alignment, and major axis is vertical with aligning direction, and distribution figure 117 at the spacing t1 on the long axis direction less than the spacing t2 on short-axis direction.Like this, at substrate by bonded to one another to a time-out, liquid crystal just can be evenly distributed on the whole base plate.

Determine that it is the figure that forms that liquid crystal distributes another factor of figure on substrate.This figure can form step difference on substrate, step difference can hinder the distribution (flowing) of liquid crystal, makes liquid crystal distribution speed difference occur.Shown in Figure 38 H, the infrabasal plate 105 as the TFT substrate in the liquid crystal panel comprises that the many pixel 106a that arrange by matrix-style are to 106c.Although not expression in the drawings, pixel 106a is limited by level or vertically arranged many gate line or data lines to 106c.And to 106c, form a TFT and a pixel electrode as driving element at each pixel 106a.

Pixel 106a is R to 106c, G and B pixel, and as forming other R on Figure 38 upper substrate that I is shown in 103, G and B color filter 104a are to 104c.R, G and B color filter 104a to 104c respectively corresponding the pixel 106a that on infrabasal plate 105, forms to 106c.And, between the chromatic filter 104a to 104c of upper substrate 103, form black bottom 108, be used for preventing black matrix layer 108 that light leaks into the non-display area of LCD be disposed in pixel 106a between the 106c in the face of in the zone, prevent that light from passing through this zone and leaking.

Figure 38 J represents a sectional view along the line of cut A-A ' among Figure 38 I.Referring to Figure 38 J, on substrate 103, form a plurality of black matrix layer 108 with setting width (this width is greater than the interval between the pixel).And between black matrix layer 108, form color filter 104a to 104c (pixel region).In this case, color filter 104a is overlapped to 104c and black matrix layer 108, but not overlapping to each other.Will on black matrix layer 108, produce the step difference of predetermined altitude like this.For general LCD, color filter 104a arranges to 104c along data line, thereby can produce step difference to 104c by color filter 104a.

This step difference can hinder liquid crystal and scatter.In addition, step difference provides the groove of aligned data line direction, and liquid crystal is scattered smootherly.When the liquid crystal of dropping on substrate was distributed on the substrate because of the substrate pressurized, step difference can form difference between the distribution speed on grid and the data line all directions.For example shown in Figure 38 K, when circular liquid crystal 107 is dripped center at substrate 105, in the distribution speed on data and the gate line direction is (do not having the distribution speed on the data line direction of step difference certainly can be fast) that differs from one another, therefore, after finishing the bonding of substrate, an oval liquid crystal 107 that has major axis and minor axis on data and gate line direction respectively will be scattered on the substrate 105.

According to the present invention, considered the influence of the figure that on substrate, forms when on substrate 105, dripping liquid crystal 107.Figure 38 M represents to distribute a kind of layout of figure 117.Referring to Figure 38 M, liquid crystal drips according to ellipse.In this case, ellipse comprises along liquid crystal and scatters the major axis of slow gate line direction and scatter the speed minor axis of data line direction faster along liquid crystal.From distributing the spacing of figure 117, spacing t2 on the gate line direction (long axis direction) is greater than the spacing t1 on the data line direction (short-axis direction that distributes figure 117), like this, at substrate by bonded to one another to a time-out, liquid crystal just can be evenly distributed on the whole surface of substrate 105.

The influence of substrate figure is actually that just TFT substrate and upper substrate 103 cause by infrabasal plate 105.In TN (twisted-nematic) type LCD, generally on TFT substrate 105, form many grids and data line.For example, the LCD with 600 * 800 pixels comprises 600 gate lines and 800 data lines.This just means that the step difference quantity on the gate line direction is more than the quantity on the data line direction.Therefore, the difference of this figure can hinder the distribution of liquid crystal on the gate line direction, and the distribution speed of liquid crystal on the gate line direction is slowed down.Yet various (organic or inorganic) insulation course that forms on the figure of TFT substrate 105 can reduce the step difference effect.Therefore, the step difference effect of the figure that forms on TFT substrate 105 is littler to the influence that liquid crystal scatters than color-filter layer.

As mentioned above, in order to drip liquid crystal, what the present invention considered has substrate shape to the influential factor of liquid crystal scattered band, the frictional direction of alignment, and the figure that forms on substrate.Above-mentioned factor can influence the dropping of liquid crystal separately.The effect of above-mentioned factor is in fact very complicated.Therefore, when calculating the distribution figure of liquid crystal, should consider substrate shape, frictional direction, and the figure that on substrate, forms.If not with friction but additive method is determined the aligning direction of liquid crystal, just might change the influential factor of liquid crystal distribution figure.For example, if determine aligning direction, just can consider figure is distributed in the photograph radiation direction or the polarization direction of irradiates light as influence factor with the aligning of taking a picture.

Below to explain the embodiments of the invention of the above-mentioned factor of actual employing, be used for illustrating the distribution figure of all kinds LCD.

At first, Figure 38 N represents a kind of distribution figure 117 of TN type LCD.In general, according to the TN pattern, on panel 105, the frictional direction of the alignment that forms on the infrabasal plate is perpendicular to one another respectively.Therefore, when reality bonding substrate, the frictional direction that is perpendicular to one another can offset the distribution speed of liquid crystal, and therefore, the frictional direction of alignment is to the not influence of distribution of liquid crystal.In this case, the frictional direction of alignment is not influence fully to the distribution of liquid crystal, but the influence of frictional direction is very little.From this point, the principal element that influences liquid crystal distribution figure 117 when the bonding substrate is figure and the substrate shape that forms on substrate.

Generally be to arrange color-filter layer, and produce a step difference along the gate line direction along the data line direction.Therefore, liquid crystal is fast on than gate line direction in the distribution speed on the data line direction.In addition, because the shape of liquid crystal panel (top liquid crystal is actual to drip on substrate) is a rectangle, on than a side direction, grow in the distribution on the rectangle diagonal.If consider the distribution distance in rectangle, the distribution figure 117 of liquid crystal preferably also is the rectangle formation by liquid crystal panel.Yet it wants fast to liquid crystal on the gate line direction at the velocity ratio on the data line direction.Therefore, as shown in the figure, distribute figure 117 little on the width on the data line direction should be than gate line direction.In other words, even liquid crystal panel 105 for analogous shape, also should form the distribution figure 117 of rectangle, make distribution figure 117 on the data line direction and the interval L1 between liquid crystal panel 105 1 sides greater than another L2 (L1＞L2) at interval between the distribution figure on the gate line direction and liquid crystal panel 105 these sides.

In addition, as dripping the distribution of liquid crystal also had material impact one that distributes figure 117 distribution spacing that drips the interval between the locational liquid crystal droplet 107.In general, drip at the locational liquid crystal 107 of the dropping that distributes figure 117 and can isotropically scatter and merge with adjacent liquid crystal (also being that isotropy is scattered).Therefore, the liquid crystal of dropping on distribution figure 117 can be fused into one and spread on the whole base plate.Specifically, on being added drop-wise to substrate after, the liquid crystal of dropping spreads to predetermined distance, touches adjacent liquid crystal before substrate bonding.If liquid crystal can not touch adjacent liquid crystal before substrate bonding, the dropping vestige of liquid crystal will be stayed on the substrate.This dropping vestige is the reason that causes the liquid crystal panel deterioration.

Therefore, accurate Calculation distributes the distribution spacing of figure 117 to preventing that the liquid crystal panel deterioration from being a very important factor with promoting liquid crystal to be distributed on the whole base plate.The distribution spacing of liquid crystal depends on the viscosity of liquid crystal or drips a dripping quantity of the liquid crystal on substrate.In TN type LCD of the present invention, preferably will distribute spacing to be set in 9～17mm.In the present embodiment, because liquid crystal is faster on the gate line direction than it in the distribution speed on the data line direction, the distribution spacing t1 of data line direction should be provided with greatlyyer than the t2 on the gate line direction, i.e. t1＞t2.

In addition, the distribution of the liquid crystal 107 of dropping on substrate can be subjected to imposing on the pressure influence of substrate.This be because, in a single day liquid crystal is added drop-wise on the substrate will be because of last, the bonded to one another and pressure that produces scatters for four times on substrate between infrabasal plate.It is desirable to, when the bonding substrate, should exert pressure equably substrate.In fact the pressure that is applied to the substrate center district is greater than the pressure that is applied to the substrate peripheral district.Like this, when liquid crystal distributes figure to drip according to the rectangle shown in Figure 38 N, the rectangular centre position towards the distribution speed of data line direction (figure and pressure to the common influence of quickening under) very fast, can before liquid crystal solidifies, arrive the sealant place.

The influence of pressure can be ignored.Yet the fault for the deterioration of eliminating LCD need overcome this negligible problem.In order to overcome stress problems, suggestion adopts the liquid crystal shown in Figure 38 O to distribute figure.

As shown in the figure, formed distribution figure 217 makes rectangle distribute the figure middle part to be removed a part on the data line direction.In other words, the width of mesozone (width of data line direction) is more medium and small than all the other districts.This distribution figure 217 can effectively prevent from because of pressure and drip the figure that forms on the substrate of liquid crystal to cause the LCD deterioration.

As can be seen from the figure, distribute figure 217 to have dumbbell shape on the whole.Certainly, so-called ' dumbbell shape ' is a kind of popular explanation, and the form range to distribution figure of the present invention is not construed as limiting.The what is called ' dumbbell shape distribution figure ' that adopts in the instructions of this paper and claims is meant at the rectangle that (on the data line direction) has a narrower width distributes the local center section that distributes figure that removes on the data line direction in the figure.

Distribute the width of the first distribution figure 217a on the data line direction that forms in the mesozone of figure 217 narrower at dumbbell shape than the second or the 3rd distribution figure 217b or the 217c that mesozone both sides form.Therefore, first distribute between figure 217a and liquid crystal panel 205 1 sides interval L3 than the second or the 3rd distribute figure 217b or 217c another at interval L1 (L3＞L1) and this difference degree are not limited only to particular value, but should be provided with the different of pressure on being applied to substrate according to the area of liquid crystal panel (or substrate) greatly.

Distribute the situation of figure the same with rectangle among Figure 38 N, dumbbell shape distributes the distribution spacing of figure 217 preferably can be provided with like this, be provided with the second or the 3rd distribution figure 217b or the distribution spacing t1 of 217c on the data line direction longer, and make first to distribute another the distribution spacing t3 of figure 217a on the data line direction than the second or the 3rd t1 length of distributing figure 217b or 217c than the t2 on the gate line direction.

For distributing figure, the rectangle of TN type LCD setting on the data line direction, has narrower width according to the present invention, or the distribution figure of dumbbell shape, like this, when liquid crystal is added dropwise on this distribution figure, just can impel liquid crystal on whole base plate, evenly to distribute.

As mentioned above, in TN type LCD, on, the aligning direction of infrabasal plate is perpendicular to one another, and can ignore the influence of aligning direction.This liquid crystal of ignoring aligning direction distributes figure also can be used for VA type LCD.Common VA type LCD does not have the specific alignment direction, therefore, can roughly distribute figure to form the distribution figure of VA type LCD by rectangle among Figure 38 N or the 38O or dumbbell shape.Thereby omitted relevant explanation to the distribution figure of VA type LCD.

Figure 38 P represents the distribution figure 317 of a kind of IPS (in-plane switching) type LCD.In general, the aligning direction of the alignment in the IPS type LCD forms towards a direction.As shown in the figure, formed aligning direction is unified into the θ angle with respect to the gate line direction.Therefore, the distribution figure 317 in the IPS type LCD depends on the shape of liquid crystal panel, the shape of figure and aligning direction.

As shown in the figure, the distribution figure 317 of IPS type LCD can be divided into two parts.In the mesozone first distributes figure 317a to extend on the data line direction.This is because according to this figure that forms on substrate, liquid crystal is fast on than data line direction in the distribution speed on the gate line direction.On the slow direction first distributes the interval L1 between figure 317a and liquid crystal panel one side to be set to the big (L1＞L2), so just can when substrate is bonded to one another liquid crystal be scattered to both direction than the interval L2 between distribution figure 317a of first on the fast direction and liquid crystal panel one side.

In TN shown in Figure 38 N or the 38O or VA type LCD, liquid crystal is fast on than gate line direction in the distribution speed of data line direction.Yet, but be that liquid crystal is very fast on the gate line direction in IPS type LCD.Below to explain its reason.

For TN or VA type LCD, color-filter layer is to arrange along the data line direction, and produces a step difference along the gate line direction.Yet in IPS type LCD, color-filter layer is to arrange along the gate line direction, and produces a step difference along the data line direction.Therefore, in IPS type LCD, the liquid crystal of dropping is very fast along the gate line lateral dispersion.A kind of glass plate (substrate just) that can be used for forming a plurality of liquid crystal panels according to the color-filter layer of this mode arrangement effectively in the above.In other words, making with the liquid crystal drop Calais in the method for LCD, according to this pattern of LCD, color-filter layer forms along grid or data line direction.The arranged direction of color-filter layer is not limited only to a specific direction certainly.Prior problem is, no matter the direction of the distribution figure of setting up in IPS type LCD is x or y direction, but this distribution figure is to go up and extend in liquid crystal slow-footed that direction (or step difference direction of color-filter layer) that flows.

Therefore, in IPS type LCD, first distributes figure 317a to extend on the data line direction, and this only is an example that distributes the figure bearing of trend.First distributes figure 317 also can extend on liquid crystal flows slow-footed any direction.

In addition, second distributes figure 317b and 317c to distribute the reverse direction extension towards each other of figure 317a two ends from first respectively.Second distributes the bearing of trend of figure 317b and 317c vertical with aligning direction.Distribution speed on each comfortable these direction of liquid crystal is slower than the distribution speed on the aligning direction, and it distributes figure 317b and 317c to compensate by second.

In IPS type LCD, it is the shape and the aligning direction of figure that liquid crystal is scattered the influential factor of speed.Therefore, when setting up the distribution figure, to consider this two factors.

Need to be based upon the spacing t1 on the data line direction particularly, the spacing t2 on the gate line direction, the spacing t3 on aligning direction, and the spacing t4 on a direction vertical with aligning direction.In general, the spacing of the distribution figure 217 of IPS type LCD is 8～13mm.

Consider the difference between the liquid crystal distribution speed that causes because of figure, be greater than t2 on the data line direction at the spacing t1 that forms on the gate line direction.Consider the distribution speed on the aligning direction, should be at the spacing t3 that is provided with on the aligning direction greater than the t4 on that direction vertical with aligning direction.

The shapeliness of the liquid crystal distribution figure of setting up in a manner described similarly is a lightning in the face of the data line direction.In other words, the distribution figure is included in the pars intermedia on the liquid crystal panel, and is becoming reciprocal afterbody with the aligning direction of alignment.The saying of Cai Yonging ' lightning ' only is for the ease of explaining in this case, is not the form range that will limit distribution figure of the present invention.

Along the distribution figure of setting up in a manner described after a liquid crystal dispensing apparatus drips liquid crystal, with substrate bonding to together.The liquid crystal of dropping is evenly distributed on the whole base plate.

Above-mentioned distribution figure calculated before dripping liquid crystal.Move a nozzle along the distribution figure that calculates and drip liquid crystal.Automatically calculate the distribution figure of liquid crystal according to the shape of substrate or the graphics shape that on substrate, forms.A divider of expression is not connected to a control system in the drawings, carries out the dropping that distributes figure and liquid crystal under the control of control system.

The various information of relevant substrate are such as substrate area, the panel quantity that on substrate, forms, the dripping quantity of liquid crystal, the shape of substrate or panel, the frictional direction of carrying out on the alignment that is formed on the substrate, shape of the figure that forms on substrate or the like is imported into control system.Control system according to the information calculations needs of input drip and total dripping quantity of liquid crystal on plate or the substrate, drip number of times, a dripping quantity, with the distribution figure, thereby a drive unit of not representing in the control chart removes to drive liquid crystal dispensing apparatus and substrate, goes up at an assigned address (position of promptly distributing figure to set) and drips liquid crystal.

In addition, if between the actual liquid crystal drop dosage on the substrate, difference occurs, can also compensate the distribution figure in the setting dripping quantity and the dropping of liquid crystal.In this case, distribute the true form of figure constant.Dot the distribution figure of various patterns in the 38P at Figure 38 N, can be used to compensate amount of liquid crystal.Specifically,, just increase or reduce the liquid crystal that drips on the graph area of distribution shown in the dotted line if between setting dripping quantity and actual liquid crystal drop dosage, difference occurs, thus the compensation amount of liquid crystal.Distribute the rectangular centre in the figure (TN or VA pattern) to form a compensating basin at the rectangle liquid crystal shown in Figure 38 N.And distribute first of figure to distribute in the mesozone of figure 217a at the dumbbell shape liquid crystal shown in Figure 38 O and form the another one compensating basin.In addition, form the another one compensating basin in the center of afterbody 317b in the distribution figure of the lightning shape liquid crystal shown in Figure 38 P (IPS pattern) and 317c.

In according to distributor of the present invention, as mentioned above, liquid crystal is added drop-wise on the substrate after the user goes out liquid crystal distribution diagram shape according to various data computation automatically.Below to explain a kind of liquid crystal drop adding method of the distributor that adopts said structure.

Figure 33 represents the process flow diagram according to a kind of LC dropping method of the present invention.As shown in the figure, if user's operation keyboard, mouse or information input from touch screen, and by the information of input block 171 input panel of LCD and other characteristic informations of panel, and the wadding height (being the box gap) that records in the step (S21) in front, dripping quantity computing unit 173 just calculates and need go up the total dripping quantity (S22) that drips liquid crystal at substrate (or panel).Calculate a dripping quantity respectively and drip number of times with dropping number of times computing unit 187 by a dripping quantity computing unit 186 then.Drip position calculation unit 188 again according to a dripping quantity with drip the dropping position that number of times calculates liquid crystal, thus calculate liquid crystal the distribution figure (S23, S24).

Move the substrate that is placed in below the distributor 120 with motor towards x and y direction.Distribute the dripping quantity of figure computing unit 175 according to input, the characteristic information of liquid crystal and information substrate calculate the position that drips liquid crystal, and moving substrate then is according to the position drive motor that should drip liquid crystal that is calculated, with distributor 120 be arranged on setting the dropping position (S27, S28).

When substrate is moved, electric power control module 177 and flow controlling unit 178 calculate the time of opening of corresponding discharge orifice 144 and the power and the air pressure (S25) of a dripping quantity of liquid crystal according to dripping quantity of liquid crystal of calculating, control power supply unit 160 and flowrate control valve 161 then and provide nitrogen for solenoid 130 power supplies and corresponding the air pressure that calculates for liquid crystal container 124.So just begin on the position of setting, to drip liquid crystal (S26, S29).

By the power of the power supply of supplying with solenoid 130 with offer liquid crystal container 124 and be used for the nitrogen supply (NS) amount of liquid crystal pressurization is determined dripping quantity one time.Change the dripping quantity that above-mentioned two factors just can be regulated liquid crystal.Or one of two factors are fixing, and change another factor and control dripping quantity.In other words, can only change the power of supplying with solenoid 130, and the nitrogen flow that will supply with liquid crystal container 124 is fixed on set amount, just can drip the liquid crystal of aequum on substrate.Also the power of supplying with solenoid 130 can be fixed on set amount in addition, and change the nitrogen flow of supplying with liquid crystal container 124, also can on substrate, drip the liquid crystal of aequum.

Simultaneously, can determine dropping dripping quantity of liquid crystal on the substrate ad-hoc location by pulling force or the interval x between pin 135 and the bar magnet 132 that regulates first spring 128.The adjusting of the pulling force of first spring 128 or interval x also can be carried out by operating personnel's direct control, preferably sets before dripping liquid crystal.

When liquid crystal was added dropwise on the substrate, the liquid crystal drop dosage that is dripped had only the trace of several mg.It is very difficult accurately dripping trace.In addition, be easier to change set amount with various factors.Therefore just need the liquid crystal drop dosage that drip be compensated, so that can on substrate, drip the liquid crystal of exact magnitude all the time.This compensation is to be carried out by the 170 included compensation control modules of the main control unit shown in Figure 28 A.

As shown in figure 34, compensation control module 190 comprises the dripping quantity measuring unit 191 of measuring the liquid crystal drop dosage, by the dropping that will record with set the compensation rate computing unit 192 that dripping quantity is compared and calculated the liquid crystal compensation amount, and distribution figure compensating unit 193, the distribution figure of the compensation rate compensation first calculated of calculating according to compensation rate computing unit 192 calculates a new distribution figure.

Although not expression in the drawings, (or outside) is equipped with a scale that is used for measuring liquid crystal weight on distributor, can the cycle or measure the weight of liquid crystal non-periodic.Liquid crystal weight often has only the trace of several mg, and measures so micro-restricted.According to the present invention is that the fixing dropping of measurement number of times for example is 10,50 or 100 times a dripping quantity, therefrom calculates dripping quantity one time.

Referring to Figure 35, compensation rate computing unit 192 comprises dripping quantity setup unit 195, the dripping quantity that a dripping quantity computing unit 186 among Figure 32 is calculated is set at current dripping quantity, comparing unit 196 will be set dripping quantity measuring unit 191 records among dripping quantity and Figure 34 dropping and compare and calculate the poor of the two, and a dripping quantity error calculation unit 197, calculate error amount with the comparing unit 196 corresponding liquid crystal drop dosage of amount relatively.

As shown in figure 36, distribute figure compensating unit 193 to comprise dripping quantity compensating unit 193a one time, it goes out the single compensation amount according to the dripping quantity Error Calculation of compensation rate computing unit 192 calculating of Figure 34, a dripping quantity compensating unit 193b, it goes out the dropping number of times of compensation according to the dripping quantity Error Calculation, one is used for calculating the dropping position compensation unit 193c that drips the position, and compensation figure computing unit 193d, it is according to a dripping quantity compensating unit 193a, and the liquid crystal that the single compensation amount that dripping quantity compensating unit 193b and dropping position compensation unit 193c calculate and the dropping number of times of compensation calculate compensation distributes figure.

The compensation of being calculated by compensation figure computing unit 193d distributes figure to comprise the dripping quantity of compensation and the dropping number of times of compensation.Like this, power control unit 197 just can calculate compensating the electric power of dripping quantity, to the signal of this calculating electric power of correspondence of power supply unit 160 output, provide the electric power of corresponding the dripping quantity according to this signal compensation to solenoid 130 by power supply unit 160.In addition, flow controlling unit 198 calculates one to compensating the pressure of dripping quantity, and to the signal of flowrate control valve 161 outputs one correspondence, the dripping quantity that flowrate control valve 161 correspondences according to the input signal compensation is distributor 120 supply air flows.

Figure 37 represents a process flow diagram according to LC dropping liquid amount compensation process of the present invention, after the liquid crystal drop that executes set point number adds, measures the dripping quantity (S31) of the liquid crystal that is dripped with a scale.Then the dripping quantity that will record is compared with the setting dripping quantity, with judge dripping quantity whether exist error amount (S32, S33).

If there is not error amount, just judge that the dripping quantity of the liquid crystal that is dripped equals set amount, therefore can continue to drip.If there is error amount, just calculate a margin of error (a time dripping quantity sum of errors drips frequency of error), so that, calculate a new distribution figure (S34) distributing figure compensating unit 193 these distribution figures of compensation.Determined one of the distribution figure that is moved to compensation at substrate drips position (S35) afterwards, calculate quantity of power error that should the dripping quantity error, thereby calculate the quantity of power of compensation, and power controlling control module 197 provides the quantity of power of calculating to solenoid 130 from power supply unit 160 by the quantity of power of calculating, thereby dripping the liquid crystal (S36 that drips compensation rate on the position, S37, S41).

In addition, compensation figure computing unit 193d calculates a pair of barometric error (S38) that should the dripping quantity error.Calculate a pair of air-flow supply that should barometric error then, thereby calculate the air-flow supply of compensation.And by Control Flow operation valve 161 from the air-flow of air supply unit 162 to liquid crystal container 124 supply one correspondence, thereby on the dropping position of compensation, drip compensation rate liquid crystal (S39, S40, S41).

Carry out the above-mentioned steps of compensation liquid crystal drop dosage repeatedly.Whenever the liquid crystal that drips set point number just repeats above-mentioned steps, so just can on substrate, drip the accurately liquid crystal of amount.

Aforesaid liquid crystal drop dosage compensation all realizes by control power supply unit 160 and dripping quantity of flowrate control valve 161 compensation.Because a dripping quantity of liquid crystal seldom, be difficult to accurately regulate a dripping quantity.For the dripping quantity of fine compensation liquid crystal, one time dripping quantity all deserves redress certainly with the dropping number of times, and this is just difficult more.Therefore, in order to simplify compensation, can compensate the liquid crystal drop dosage by only compensating liquid crystal dropping number of times to dripping quantity.' compensation liquid crystal drop dosage ' means by compensating the distribution figure for the new dropping position of setting of distribution graphics calculations.

Compensating under the situation of distributing figure, do not revise basic distribution figure by compensation dropping number of times.Because the distribution figure that calculates has comprised liquid crystal and has dripped all required factors that calculating new distribution diagram is difficult just as sample.Therefore, if compensate the liquid crystal drop dosage according to the present invention, dripping quantity is to distribute figure to compensate with the previous liquid crystal that calculates.When dripping liquid crystal at first (before the compensation), liquid crystal is not added drop-wise to all liquid crystal and distributes on figures.At Figure 38 A, the distribution figure 26a that represents with solid line among 38B and the 38C is the distribution figure of compensation, and another distribution figure 26b that dots is the distribution figure that needs compensation.Specifically, if measure dripping quantity, will compensate the additional allocation figure 26b that dotted line is represented less than setting dripping quantity (being that amount of liquid crystal increases).And the extra liquid crystal that drips on these positions.In addition, surpassed the setting dripping quantity if measure dripping quantity, just removed dotted line distribution figure the figure from setting to distribute, the distribution figure 26b that stops at correspondence goes up and drips liquid crystal.

Hereinbefore, liquid crystal 26 is dripped on first substrate 10 as tft array substrate, and silver point and sealant 30 are applied on second substrate 20 as color filter array substrate.Yet according to the pattern of LCD, liquid crystal 26 also can drip on second substrate 20 as color filter array substrate, and silver point and sealant 30 can be formed on first substrate 10 as tft array substrate.

Below to explain adhesion step.

In this case, determine to disturb the mobile route of each finger of the first arm 310 at least in the face of the installation interval between unidirectional each first support portion 420a of the load/unload direction of first substrate 10.

For example shown in Figure 42, if the first arm 310 that forms has three fingers 311 by arranged at predetermined intervals, each first support portion 420a just is among the interval s that forms between each finger 311, can not disturb the motion of the first arm 310.

In addition, be installed on the direction vertical and some position of other first support portions 420b of being mounted with each finger 311 of the first arm 310 bends in the above downwards, avoid interference each finger 311 with the load/unload direction of first substrate 10.As shown in the figure of one embodiment of the invention, the middle part is bent downwards, avoid interference the middle finger of the first arm 310, and form each sidepiece of sufficient length, avoid touching each finger (or make each finger that is positioned at the first arm both sides have certain interval surplus, not disturbed by the first support portion 420b) of the first arm 310 both sides.

Simultaneously, if adopt first support portion 420a and the 420b with sufficient length on the device of making large-scale LCD, the two ends of the

first support portion

420a and 420b can be sagging.

The present invention advises that also each installs at least two first lifting shaft 420c on first support portion 420a that faces with each other and 420b, they axially are connected with 420b with the first support portion 420a, and first drive division 421 (referring to Figure 44) that is used for driving the first lifting shaft 420c lifting is installed.

For example, according to a kind of layout, each the first lifting shaft 420c that is connected to first drive division 421 is installed in crossover sites between each support portion 420b from vertical direction, and be installed in crossover sites between each support portion 420a, or be installed in the centre of each

first support portion

420a and 420b and a corresponding position between the two ends from horizontal direction.

According to said structure, be preferably in a kind of coating material of coating (not expression among the figure) on those faces that comprise at least on the first support portion 420a and the 420b with the surface of contact of first substrate 10, when the

first support portion

420a and 420b touch first substrate 10, avoid causing such as above-mentioned various damages such as scratches because of contacting between substrate and the first support portion 420a and the 420b.

The present invention specifically adopts Teflon, and peak or conductor can prevent to abrade substrate like this as coating material, the impact of vibrations, and the generation of static.

The

first support portion

420a and 420b preferably form rod, wire nail, hollow polygon pipe or the like.Yet, be not limited only to these compositions according to embodiments of the invention, can also adopt different shape with reference to all kinds.

First drive division 421 of forming first baseplate support device 420 comprises at least one stepper motor and utilizes on normal air or the oil pressure oil cylinder of following mobile lifting shaft.Preferably first drive division 421 is fixed on the lower space of vacuum chamber 210 inboards.And the bottom that preferably allows first drive division 421 penetrate vacuum chamber 210 is fixed in the space in vacuum chamber 210 outsides.Like this, embodiments of the invention just can prevent to disturb various driving arrangements and be convenient to install.

For this reason, as shown in figure 45, the present invention advises adopting following a series of structures.On the top circumference of lower table 222 both sides of a direction vertical, form at least one second acceptance division 222e, allow its form a groove or penetrate form with the load/unload direction of substrate.And with clamping device 700 of the corresponding second acceptance division 222e selective reception.

Specifically, clamping device 700 selected being received among the second acceptance division 222e, can be in the both sides lifting of lower table 222 top circumference, thus the circumferential location of first substrate 10 and bonding substrate when loading first substrate 10 or unloading bonding substrate, supported.Can prevent that so also corresponding position is sagging.

Above-mentioned clamping device 700 is received in the second acceptance division 222e inboard, and be positioned in the both sides of lower table 222 at first, and comprise at least one second support portion 710, be used for supporting the two bottom sides of first substrate 10, one is made in one second lifting shaft 720 and second support portion 710, goes up selectively, move second support portion 710 down, and one second drive division 730 is connected to second lifting shaft 720, drives selectively on second lifting shaft 720, move down.

The second acceptance division 222e of Xing Chenging is along having predetermined length with the corresponding position of the virtual area of first substrate 10 in this case, first substrate is placed in top circumference both sides corresponding on the lower table 222, and the length correspondence that second support portion 710 that forms is had the shape of the second acceptance division 222e, so that can support the circumference of first substrate 10.

Specifically, second support portion 710 of formation has curved shape, can support the bottom of first substrate 10 with one side, and simultaneously supports the transverse side of first substrate 10 in addition.The one side that touches substrate is coated with coating material (not expression in the drawings), avoids substrate to cause damage because of the contact between second support portion 710 and first substrate 10.

In this case, coating material is Teflon with the same of the

first support portion

420a and 420b, and peak or conductor can be avoided producing static because of touching substrate.

Formed second lifting shaft 720 has identical structure with second drive division 730 with the above-mentioned first lifting shaft 420c and first drive division 421.Yet the present invention is not limited only to this structure, and concrete explanation has just been omitted.

In addition, one can be made along the whole circumference of lower table 222 in second support portion 710 in the said structure.Yet, provide a plurality of second support portions 710 that are separated from each other according to the embodiments of the invention suggestion, so that staying predetermined interval (being enough to avoid the sagging minimum sagging limit that substrate allows that surpasses) to each other.

In this case, an end of each second support portion 710 is made into one, and at least one second lifting shaft 720 and second drive division 730 are installed in second support portion, 710 1 ends of making one, so that can operate each second support portion 710 smoothly.

The sequence of operation of above-mentioned clamping device 700 and first baseplate support device, 420 compounding practices.

Specifically, second drive division 730 of forming clamping device 700 is cooperating first drive division 421 of forming first baseplate support device 420 to operate simultaneously, go up selectively, move second lifting shaft 720 and second support portion 710 down, so just can when first substrate 10 and bonding substrate are loaded and unloaded, support the circumference of first substrate 10 and bonding substrate respectively.

In addition, the structure of above-mentioned second baseplate support device and mode of operation are as follows.

Figure 46 represents the synoptic diagram of a bonding machine of vacuum, is equipped with in the above according to second bracing or strutting arrangement of the present invention.

Second baseplate support device 400 of forming bonding machine of the present invention is to constitute like this, makes it can touch a virtual area between the box district that is formed on second substrate, 20 bottoms.Second baseplate support device 400 comprises the turning axle 415 that can rotate on a large scale, supporter 412 and a drive division 411.Second baseplate support device 400 is installed in an adjacent position of transverse side of vacuum chamber 210 bottom inside and lower table 222.

Suggestion employing quantity is 2 to 10 second baseplate support device 400 in this case.

Specifically, if see the layout of vacuum chamber 210 inside from second baseplate support device, 400 1 sides, an end that is connected to turning axle 415 on the supporter 412 is set at the inside bottom of vacuum chamber 210, the bight on each

worktable

221 and 222 long limit (or minor face) just, or be arranged on the adjacent position (or in position of leaving fixed intervals) of center section with the long limit (or minor face) of each worktable 221 and 222.And an other end of supporter 412 is arranged to inboard facing to each worktable.

Specifically, second baseplate support device of being installed 400 is set near the bight (or two bights) of a widthwise edge of lower table 222, or is arranged near the another one bight (or two bights) of a widthwise edge of lower table 222.Or second baseplate support device 400 is installed like this, it is arranged near the middle part of one or another widthwise edge of lower table 222, or can be installed in each angle and pars intermedia simultaneously.If second baseplate support device 400 is installed near the middle part of one or another widthwise edge of lower table 222, a plurality of baseplate support devices can also be installed in the above.

In this case, form the supporter 412 of second baseplate support device 400 and an end of turning axle 415 and be made into one.The supporter 412 that forms along diagonal from second substrate 20 that is fixed on upper table 221 bottoms widthwise edge or extend along the direction of another widthwise edge, select to carry out rotatablely moving simultaneously by turning axle 415.Or formation can be installed to a locational bearing that can not disturb each working table movement.

In addition, on the top of supporter 412, form at least one supporting projections 413, so that dwindle the contact area with second substrate as far as possible.Specifically, when below supporter 142 is positioned at upper table 221, the position of regulating supporting projections 413 its correspondence to be fixed on the position of a virtual area of second substrate 20 on the upper table 221.

Each supporting projections 413 of Xing Chenging has identical rising height in this case.Yet should can regulate the rising height of each supporting projections 413 where necessary so that form different height.

If will form an interval between 413, two supporting projections 413 of at least two supporting projections of formation on the top of supporter 412, the distance that is provided can prevent that substrate is extremely sagging.

Specifically, consider that forming many supporting projections 413 will make the interval between each supporting projections 413 narrow down inevitably, and can be sagging during the interval broad of the concrete position of second substrate 20 between each supporting projections 413, when determining arrangement interval, should reduce the problems referred to above as far as possible.

Yet, consider the arrangement that can change optimal spacing between the supporting projections according to the model and the size of each substrate, preferably when forming each supporting projections, can regulate interval to each other, so that be fit to the substrate of various sizes.

According to the present invention, the position of second baseplate support device 400 can be located at a side with a widthwise edge of lower table 222 (just long limit or minor face) at a distance of the position of certain intervals, or is located at centre or a bight of widthwise edge.

In this case just can be in advance according to substrate size, the load/unload direction of substrate waits to determine the position of structure.Specifically, preferably according to the sense of rotation of supporter 412, substrate, and the contact position of supporter is determined centre or a bight at widthwise edge.

In addition, according to the present invention, preferably second baseplate support device 400 is installed on the long limit of lower table 222 and is not installed on the minor face.Because the integral layout of vacuum bonding machine is a rectangle, the excess room on the minor face is little, and space abundance on the long limit.Therefore, preferably second baseplate support device 400 is installed along long limit with enough excess room.

The supporter 412 that is installed in second baseplate support device 400 at position of living in, a long limit may the phase mutual interference.Therefore preferably form supporter intersected with each other 420.

Yet embodiments of the invention are not limited only to said structure.Also can change the mounting means of each second baseplate support device 400, with each middle part or the fixing interval of reservation, bight of lower table 222 each limit (long limit or minor face), so just can not the phase mutual interference.

The drive division 411 of forming second baseplate support device 400 comprises at least one oil cylinder, utilize air or oil pressure rotate turning axle or on, following mobile turning axle, and a turning motor, it utilize steering force rotate turning axle or on, following mobile turning axle.

If drive division 411 comprises oil cylinder and turning motor simultaneously, oil cylinder just is used for, following mobile turning axle, and motor is used for turning right and moving turning axle in a left side.Can certainly use an oil cylinder left side, the moving turning axle of turning right, and with on the motor, following mobile turning axle.

If the position of making the supporter 412 of one with turning axle 415 exceeds the top of lower table 222, drive division just only needs a left side, the structure of the moving turning axle 415 of turning right.In this case, loading part 300 might cause interference in the load/unload process of substrate.The initial position of supporter 412 should be lower than the top of lower table 222, and drive division comprises, a following mobile turning axle 415 and a left side, the dual structure of the moving turning axle 415 of turning right.

The present invention also advises adopting the structure that drive division is located at vacuum chamber 210 outsides.

This is for fear of if drive division is installed in each parts interference problem of bringing vacuum chamber 210 inside (interference that forms just) with each arm 310 of loading part 300 and each substrate of 320 load/unloads the time, and requires vacuum chamber 210 that enough inner spaces are arranged.

In this case, the turning axle 415 of accepting the driving force of drive division 411 transmission is installed into the bottom that can penetrate vacuum chamber 210, and execution sealing on piercing site (not expression in the drawings) is in order to avoid air inflow/outflow.

A pair of second baseplate support device 400 has been installed in Figure 46, with the angle on each long limit of lower table 222 at a distance of predetermined space, can prevent the privileged site excessive sag of second substrate like this.Can certainly constitute pairing with at least three second baseplate support devices 400 in addition.

If by at a distance of predetermined space two second baseplate support devices 400 being installed respectively with the pars intermedia or the bight of a widthwise edge of lower table 222, first bearing 417 of forming one of two second baseplate support devices 401 is made into shorter than another second bearing 416 of 402 in the middle of forming two second baseplate support devices.Second baseplate support device 401 is installed in the position than another second baseplate support device, 402 more close lower tables 222.And the first turning axle 417a and the 417b that form second baseplate support device 401 can be offset each other with the second turning axle 416a and the 416b that form another second baseplate support device 402.

In this case, as shown in FIG., formed second turning axle 416a and 416b be than the minor face of the first turning axle 417a and the more close lower table 222 of 417b, so just can allow first and second turning axles blocked operation each other.

Such structure can be loaded in the process of working position at each supporter 416 and 417 of rotation and prevent various operations mutual interference mutually.

Specifically, drive first and second baseplate support devices 401 and 402 number of times and be set to differently, so just can prevent the mutual interference of various operation phase.

Below to explain the step S13 that adopts above-mentioned bonding machine bonded liquid crystal displays.

Figure 47 represents the process flow diagram according to a kind of LCD adhering method of the present invention, and Figure 48 A represents sectional view according to a kind of LC dropping type LCD manufacture method of the present invention to 48E.

May further comprise the steps according to adhesion step of the present invention, two substrates are loaded in the vacuum chamber, in vacuum chamber, form vacuum, two substrates align, substrate is bonded to one another, discharge vacuum chamber so that the substrate that bonds is pressurizeed, and the substrate that unloading bonds from vacuum chamber.

In loading step, shown in Figure 48 A, second substrate 20 overturns, be coated with the position faced downwards of sealant, it is fixed on the upper table 221 of vacuum chamber 210 (S51), and has first glass substrate 10 of liquid crystal 26 to be fixed on the lower table 222 of vacuum chamber 210 (S52) top dropping.In this case, vacuum chamber is kept atmospheric condition.

Specifically, use the first arm 310 of the finger 311 of conveying device 300 that second substrate 20 is overturn, make the position faced downwards that is coated with sealant, put into vacuum chamber 210 then.When keeping this state, fall the upper table 221 of vacuum chamber 210, with pull of vacuum that second substrate 20 is fixed thereon, promote then.Can replace pull of vacuum with electrostatic attraction in this case.

After the first arm 310 of the finger 311 of conveying device 300 leaves vacuum chamber 210, there is first substrate 10 of liquid crystal 26 to be placed in the vacuum chamber 210 top dropping with conveying device 300, promote the clamping device (not shown) and first baseplate support device 420 then, first substrate 10 is separated with conveying device 300.After conveying device 300 is left vacuum chamber 210, the clamping device and first baseplate support device 420 are dropped on the lower table 222.And it is first substrate 10 is fixed thereon by lower table 222 usefulness pulls of vacuum.Can replace pull of vacuum with electrostatic attraction in this case.

If a substrate of top formation tft array is called first substrate 10, and another substrate of top formation color filter array is called second substrate 20, sealant is coated on first substrate 10, and liquid crystal drop is added on second substrate 20.Or on one of two substrates sealant, and on the substrate of sealant, drip liquid crystal.Yet dripping has that substrate of liquid crystal will be placed on the lower table 222, and another one is placed on the upper table 221.

Second baseplate support device (glass receiver) 400 is placed under second substrate 20 that is fixed on the upper table 221 in order to support second substrate 20 (S53).Second baseplate support device 400 supports second substrate 20 in the following manner.

At first put down upper table 221 or promote second baseplate support device 400, allow second baseplate support device 400, remove the vacuum power or the static power of the upper table 221 that keeps second substrate 20 then near below second substrates 20.

Secondly put down upper table 221 by preliminary preset distance, promote second baseplate support device 400 then for the second time.So just can allow second baseplate support device 400 near below second substrate 20.Remove the vacuum power or the static power of the upper table 221 that keeps second substrate 20 then.

Why the following reason that second baseplate support device 400 is placed on second substrate 20 in this case is as follows.

When vacuum chamber 210 inside form vacuum, because the vacuum tightness of vacuum chamber 210 inside is than the vacuum tightness height of each worktable, each

worktable

221 and 222 usefulness pulls of vacuum keep first and

second substrates

10 and 20, and

worktable

221 and 222 self has been lost suction because of being used for first and second substrates 10 and 20.Like this, if upper table 221 loses suction, will drop on first substrate 10 attached to second substrate 20 on the upper table 221.

In order to prevent that second substrate from falling when forming vacuum, before vacuum chamber 210 forms vacuum, second baseplate support device 400 is placed on following support second substrate 20 of second substrate 20 that is attached on the upper table 221.

So just can be at the vacuum chamber 210 inner vacuum states (S54) that obtain.In this case, the vacuum tightness of vacuum chamber 210 changes with the corresponding liquid crystal pattern.Specifically, the vacuum tightness of IPS pattern is set at 1.0 * 10 ^-3Pa is between the 1Pa, and the vacuum tightness of TN pattern is 1.1 * 10 ^-3Pa to 10 ²Between the Pa.

In addition, can realize the vacuum state of vacuum chamber 210 inside in two steps.Specifically, substrate is attached to, on the lower table 221 and 222, closes the door of vacuum chamber 210, start first vacuumizing with a dry vacuum then.When carrying out first vacuumizing, carry out second vacuumizing with a high vacuum pump.

The reason why vacuum chamber forms vacuum by two steps is the possibility that deforms or move because of the rapid change of the vacuum state of vacuum chamber 210 inside for the substrate that prevents in the vacuum chamber.

In case the vacuum state of vacuum chamber 210 inside reaches predeterminated level, on, lower table 221 and 222 just is separately fixed at (S55) on it with electrostatic charge suction with first and

second glass substrates

10 and 20, and second baseplate support device 400 returns its original position (S56).

In this case, at least two battery lead plates that are located on the worktable are applied negative/positive DC power and produce electrostatic charge suction.Specifically, if each battery lead plate is applied plus or minus voltage, will on worktable, induce the negative or positive electric charge.Owing on substrate, be provided with conductive layer (for example common electrode, transparency electrodes such as pixel electrode), substrate because of the Coulomb force that produces between conductive layer and the worktable by sticking.If have the one side of conductive layer on the substrate is a side that is positioned at worktable, just applies the voltage between 0.1 to 1kV betwixt.If have the one side of conductive layer on the substrate is a relative side that is positioned at worktable, just applies the voltage between 3 to 4kV betwixt.In this case can be on upper table 221 flexure strip of sticking.

Fix respectively with electrostatic charge suction, after the lower table 221 and 222, two base plate alignments (S57).

Aligning is carried out in the following manner, and the two kinds of alignment marks (thick, thin mark) that are engraved in respectively on first and

second substrates

10 and 20 are aimed at successively.

When being loaded into two

glass substrates

10 and 20 on each

worktable

221 and 222, shown in Figure 48 B and 48C, upper table 221 being moved down, thereby make first and

second substrates

10 and 20 be bonded to together (pressurization for the first time) (S58) with electrostatic attraction.Carry out bonding in this case in the following manner, 222 pairs of substrate pressurizations of mobile in vertical direction upper table 221 or lower table.The translational speed and the pressure that change the relevant work platform in this case pressurize.Specifically, that that touches that second substrate 20 or the sealant 30 of second substrate 20 touch first substrate 10 at the liquid crystal 26 on first substrate 10 constantly before by at the uniform velocity travelling table or pressurization, progressively pressure is increased to resulting pressure from time of contact then.Specifically, a load units is installed in a moment that upward contacts with identification of travelling table, and by various pressure two

substrates

10 and 20 is bonded to together, the pressure of time of contact is 0.1 ton, interstage is 0.3 ton, and follow-up phase is 0.4 ton, and final stage is 0.5 ton.

In this case, axle of upper table 221 usefulness is carried out substrate bonding.Or various axles are installed, allow have independently each independent execution pressurization of load units (device of gaging pressure).If lower table 222 and upper table 221 not on same level, just can not be finished uniform bonding with sealant 30, the axle of corresponding site or light or important place pressurization are so that finish uniform bonding with sealant 30.

Substrate

10 and 20 is fixed, in order to avoid in subsequent step, will be bonded to together

substrate

10 and 20 distortion.

After finishing said fixing, stop static sticking (ESC closes).Shown in Figure 48 D, promote upper table 221 then upper table 221 is separated with 20 with the substrate 10 of bonding.

In order to make vacuum chamber 210 reach atmospheric pressure and the substrate that bonds evenly to be pressurizeed, for example be that nitrogen or the dry air of cleaning discharge vacuum chamber 210 (S60) for vacuum chamber 210 provides a kind of gas.

In case vacuum chamber 210 discharges, and just form vacuum state between first and

second substrates

10 and 20, and vacuum chamber 210 becomes atmospheric pressure.Like this, first and

second substrates

10 and 20 in the vacuum are just kept uniform gap because of being pressurizeed by atmospheric pressure.In this case, first and

second substrates

10 and 20 pressurizeds of bonding, the same release of the nitrogen of input or dry air becomes atmospheric pressure.

The most important thing is when discharging vacuum chamber 210,

substrate

10 and 20 evenly to be pressurizeed.Pressure should evenly offer each position of two

substrates

10 and 20, forms the sealant 30 of equal altitudes between

substrate

10 and 20, and liquid crystal 26 is uniformly scattered onto above all sites.So just can avoid sealant 30 sharply to expand or the liquid crystal deficiency of packing into.For all sites to substrate when discharging vacuum chamber 210 pressurizes, the direction that gas flows into during release direction vacuum chamber 210 releases just is very important.

Therefore, the present invention has adopted following embodiment.

At first form a plurality of pipelines to the vacuum chamber injecting gas on vacuum chamber top.Second forms a plurality of pipelines to the vacuum chamber injecting gas in the vacuum chamber bottom.The 3rd forms a plurality of pipelines to the vacuum chamber injecting gas in the vacuum chamber side.The 4th allows said system move simultaneously.Preferably from vacuum chamber top injecting gas.Yet also can be according to substrate size, state of worktable or the like is determined release direction.

In addition,

substrate

10 and 20 all is subjected to the pressure and the atmospheric pressure of gas injection force when discharging.The pressure that applies thereon when discharging is atmospheric pressure (10 ⁵Pa) or per unit area (cm ²) 0.4～3.0kg/cm ², with 1.0kg/cm ²Be the best.Yet also to consider substrate size, substrate distance, sealant thickness or the like is revised pressure.

Can form at least two gas injection tubes.Preferably determine the quantity of gas injection tube according to substrate size.Be the best to form 8 gas injection tubes in this case.

In order to prevent that substrate from swinging when vacuum chamber discharges, can prevent substrate swing (drift) with a stationary installation or system.

Substrate can be swung when vacuum chamber is discharged rapidly, might cause the substrate dislocation.Therefore gas can be progressively discharged, and a valve supply gas progressively at a slow speed can be increased.Specifically, vacuum chamber discharges consistently.Or from beginning slowly to carry out first release, in order to avoid the substrate swing to predetermined instant.Revise release rate then and carry out second release, so that comparatively fast reach atmospheric pressure.

The timing that gas injects is very important, because vacuum chamber release can cause the substrate of bonding to swing on worktable or misplace.

Relevant release time, aim at that pressurization is for the first time carried out in the back and when forming vacuum state between two substrates, vacuum chamber begins to discharge finishing.The method of below wanting specific explanations to begin to discharge.

At first, after finishing lifting, upper table begins to discharge.The second, begin to discharge in the upper table lifting, to shorten the processing time to carrying out between finishing.

The 3rd, when promoting upper table, just begin to discharge.In this case, upper table is blown into upper table along with gas or dry air and rises.The substrate of bonding is not easy to fall down from lower table from the upper table dismounting or because of swinging.Therefore, just can promote upper table when being blown into gas or dry air, easy like this substrate and the upper table of making separates.

The 4th, vacuum chamber begins to discharge when finishing bonding, does not move lower table.In this case, mobile upper table after vacuum chamber is finished release, or before vacuum chamber is finished release, begin mobile upper table.In addition, gas or dry air are blown into upper table, make on the upper table and move.The substrate of bonding is not easy to fall down from lower table from the upper table dismounting or because of swinging.Therefore, just can promote upper table when being blown into gas or dry air, easy like this substrate and the upper table of making separates.

Then will be because of the substrate unloading (S61) of release pressurized.Just on finishing when discharging, move, with first and

second substrates

10 and 20 unloadings of the loading bin of mechanical arm pressurized with upper table 221.Or the loading bin with mechanical arm unloads carried

base board

10 and 20 from upper table 221 after first and

second substrates

10 and 20 of upper table 221 sticking pressurizeds rise.

In this case, in order to shorten the processing time, the first and second

new substrates

10 and 20 that needs can be carried out next adhesion step are loaded on the upper table, and first and second substrates of pressurized are unloaded.That is to say that second substrate that the next one need be carried out adhesion step with the loading bin of mechanical arm is put on the upper table 221, be fixed on the upper table that first and

second substrates

10 and 20 with pressurized on the lower table 222 unload then with pull of vacuum.Or the lifting upper table 221 of suction sticking first and

second substrates

10 and 20, to need to carry out next time in the above with the loading bin of mechanical arm that the first new substrate 10 of adhesion step is loaded on the lower table 222, then with first and second substrates unloading of pressurized.

In said process, can increase liquid crystal and scatter handle, substrate is glued to together after and the liquid crystal on the substrate of bonding is scattered towards sealant.Or after finishing unloading step,, just can carry out liquid crystal distribution step in addition and make liquid crystal towards the sealant uniformly dispersing if liquid crystal can not scatter.In this case, liquid crystal scatters step and will carry out at least 10 minutes, and can carry out under atmospheric pressure or vacuum.

Below to explain in the bonding machine two substrates that are bonded to are together carried out the unit step S14 that UV solidifies.

Figure 49 A and 49B are illustrated in the detailed schematic according to a UV curing schedule in the LCD manufacturing step of the present invention.

With the whole surface of UV radiation exposure bonding substrate, the feature of the device of sticking such as thin film transistor (TFT) etc. and is changed for preliminary pre-tilt angle of aiming at the alignment of liquid crystal sticking by aging on substrate in the UV irradiating step that UV solidifies.One embodiment of the invention is directly to use all the other areas of mask shielding, and the sealant on the bonding substrate forms and carries out the UV radiation exposure in the district.

Referring to Figure 49 A, mask 80 is placed on above the bonding substrate, shield all the other zones, only stay the zone that will form auxiliary UV curing sealant 30a and main UV curing sealant, shine the UV ray then in the above.

As seen from the figure, mask 80 is set at above the bonding substrate.Also can be arranged on then the bonding substrate below.In addition, only represented irradiation UV ray on the face of second substrate 20 of bonding substrate among the figure.Perhaps also the bonding substrate overturn can be come, use a face of first substrate of UV radiation exposure bonding substrate.

Simultaneously, if offer opposite one side after the UV ray of UV irradiation unit 90 emission is reflected, just can make the characteristic of TFT, alignment or the like wears out.Therefore, can the bonding substrate above and below form dual mask respectively.

In addition, auxiliary UV curing sealant 30a needn't carry out the effect of sealant, thereby does not need to solidify.In addition, the zone of the auxiliary UV curing sealant 30a of formation is overlapping as meeting in the unit cutting step of subsequent step in the unit line of cut.Therefore, it is better that curing ratio curing is not wanted in this zone.

Therefore, remove extra-regional all the other zones and use mask shielding, shown in Figure 49 B, use the UV radiation exposure then, auxiliary UV curing sealant 30a can not solidified with main UV curing sealant.

In this case, mask 80 can be arranged on the top of the bonding substrate that is used for the UV radiation exposure or below.Or on be used for the bonding substrate of UV radiation exposure and below mask 80 (in the drawings not expression) is set respectively.

Be formed for the mask that UV solidifies in addition, only the active area in sealant 30 inside blocks the UV ray, and the UV ray is applied on sealant and the virtual area.Can effectively shine the UV ray in this case, can not be applied to position masked or the belt shielding, overlapping at the zone and the unit line of cut that form auxiliary UV curing sealant 30a.

In above-mentioned steps, the UV ray offers second or first substrate according to the LCD pattern of correspondence.Specifically, the IPS pattern is applied the UV ray from second substrate, one side sealant 30 is solidified, the TN pattern is applied the UV ray from first substrate, one side.Because sealant is formed in the black matrix layer outside and is formed on the black matrix layer in TN type panel of LCD in IPS type panel of LCD, the UV ray should accurately shine on the sealant.Even accurate performance element cutting step after the UV that finishes the bonding substrate solidifies if sealant is UV and heat reactive resin, also needs to carry out subsequently thermal cure step S15.

Thermal cure step is carried out in the following manner, the bonding substrate of finishing the UV curing schedule is placed in the heat curing stove solidified one hour by about 120 ℃.

Then according to unit panel performance element cutting step S16 on the substrate of finishing UV and thermal cure step.

Figure 54 represents to be separately positioned on the another kind of synoptic diagram in the suction hole on first to the 4th mesa surfaces of Figure 53 A in the 53G, and Figure 55 A and 55B represent the detailed schematic of first and second scribe step that adopt according to all embodiment of the present invention.

Figure 56 A represents detailed schematic according to the continuous scribe step of fourth embodiment of the invention to 56F.

As shown in figure 50, cutter sweep according to one embodiment of the invention comprises load units 800, top first and

second substrates

10 and 20 that are furnished with a plurality of cell liquid crystal display panels are loaded aligning, first and

second substrates

10 and 20 have been glued to together at this moment and have solidified, first scribing unit 810, on first, lower whorl forms first line and with first cylinder at least a portion of first line is exerted pressure on first and

second substrates

10 and 20, cut first and

second substrates

10 and 20 successively, first rotary unit 820, first and

second substrates

10 and 20 half-twists with cutting, second scribing unit 830, on second, lower whorl forms second line and with second tin roller at least a portion of second line is exerted pressure on first and

second substrates

10 and 20, cut first and

second substrates

10 and 20 successively, and unloading unit 840, be used for unloading first and

second substrates

10 and 20 that cut down by first and

second scribing units

810 and 830, so that the cell liquid crystal display panel is sent to the device of execution subsequent step.

Simultaneously, Figure 51 A is illustrated in the concrete synoptic diagram of the subsequent step of carrying out in each frame of Figure 50 to 51G, can explain cutter sweep and method thereof according to the panel of LCD of one embodiment of the invention in detail with reference to these figure.

Referring to Figure 51 A, on first and

second substrates

10 and 20 that are bonded to face-to-face together, form tft array substrate and filter substrate.First and

second substrates

10 and 20 that will bond in load units 800 are loaded on first table top 801, aim at by alignment mark 802 then.

In this case, be loaded on first table top 801, be placed on above second substrate 20 as color filter array substrate as first substrate of tft array substrate.

Because grid and data pads are formed on the left side of tft array substrate respectively, one side of right and last, a side of following direction, first substrate, 10 to the second substrates 20 are more outstanding, therefore, it is bigger than the another one substrate with color filter array to have a size of first substrate 10 of tft array.So just can prevent that virtual substrate from causing damage because of gravity descends in the unit cutting step.

Referring to Figure 51 B, in first scribing unit 810, first and

second substrates

10 and 20 move between first table top 801 and second table top 803 by predefined distance, keep predetermined gap with first table top 801, simultaneously, in the gap that between first table top 801 and second table top 803, stays, respectively on first and

second substrates

10 and 20 surfaces with first on,

lower whorl

804 and 805 form successively first the

line

806 and 807.

In this case, wheel 804 and the interior reference line R1 one side reservation distance in tft array substrate (first substrate 10) district on first, this side is more side-prominent than color filter array substrate (second substrate 20) last corresponding, thereby forms first line 806 on the surface of first substrate 10.And first lower whorl 805 and reference line R1 reservation distance at a distance of preset distance, rule 807 thereby form first on the surface of second substrate 20 on the opposite direction of wheel 804 on corresponding first.

Simultaneously, on first,

lower whorl

804 and 805 does not form the zone interior (just tft array substrate is not from the outstanding zone of color filter array substrate) of first substrate 10 of grid or data pads in the above and aims at each other identically, forms

first line

806 and 807 respectively on the surface of first and

second substrates

10 and 20.

Referring to Figure 51 C, exerted pressure in the line of first in first scribing unit 810 806 and 807 positions respectively with first cylinder 808, cut first and

second substrates

10 and 20 successively.

Exerting pressure at least one position of first line 806 that first cylinder 808 forms wheel on first 804 simultaneously, makes the crack pass through

first line

806 and 807 expansion on first and

second substrates

10 and 20.

Simultaneously, when on first substrate, 10 surfaces, form first line 806 first on wheel 804 when returning its original position, wheel 804 compounding practices on first cylinder 808 and first move applied pressure along first line 806, so just can exert pressure to first line 806 more effectively.

In addition, first cylinder 808 can be separately be exerted pressure to being formed on 20 lip-deep first line of second substrate, or simultaneously to being formed on first and

second substrates

10 and 20 lip-deep

first line

806 and 807 are exerted pressure.

As mentioned above, first cylinder 808 is exerted pressure in the mode that touches first substrate 10 with tft array substrate.Therefore, first cylinder 808 is preferably made with elastomeric material, is not easy to slide on glass substrate, has good static characteristic, and does not produce particulate.

Referring to Figure 51 D, first and second substrates 10 after the cutting and 20 are rotated 90 ° in first rotary unit 820.

Referring to Figure 51 E, in second scribing unit 830, first and

second substrates

10 and 20 of rotation are moved a preset distance, arrive between third and

fourth table top

811 and 812, keeping at a distance to each other by uniform distance, simultaneously, on second in the insulating space between third and

fourth table top

811 and 812,

lower whorl

813 and 814 forms

second line

815 and 816 successively on first and second substrate surfaces.

Described as reference Figure 51 B, on first, lower whorl 804 is the same with 805, on second,

lower whorl

813 and 814 and tft array substrate (first substrate 10) district in reference line R1 one side keep predetermined distance to each other, this side is more side-prominent than filter substrate (second substrate 20) last corresponding, thereby forms

second line

815 and 816 on first and

second substrates

10 and 20 surfaces.And not from that outstanding zone of color filter array substrate, on second,

lower whorl

813 and 814 is aimed at identically each other at tft array substrate, thereby formation second rules 815 and 816 on the surface of first and

second substrates

10 and 20.

Referring to Figure 51 F, in second scribing unit 830, exerted pressure in each position of

second line

815 and 816 respectively with second tin roller 817, cut first and

second substrates

10 and 20 successively.

Described with reference to Figure 51 C as mentioned, second tin roller 817 is exerted pressure at least one position of second line 815 that formed by wheel 813 on second simultaneously, makes the crack pass through

second line

815 and 816 and expands on first and second substrates 10 and 20.Simultaneously, when on first substrate, 10 surfaces, form second line 815 second on wheel 813 when returning its original position, wheel 813 compounding practices on the second tin roller 813 and second move applied pressure along second line 815, so just can exert pressure to second line 815 more effectively.Second tin roller 817 is preferably made with the elastomeric material with less friction, and it has good static characteristic, and the particulate that produces seldom.

Referring to Figure 51 G, will send the device of carrying out subsequent step to along first and second line 806,807, the 815 and 816 cell liquid crystal display panel of cutting successively with unloading unit 840.

State when being sent to load units 800 with panel of LCD is compared, and shown in Figure 51 G, Qie Ge cell liquid crystal display panel has been turned over 90 ° in order.The cell liquid crystal display panel has been turned over 90 ° because of insert second rotary unit 850 in unloading unit 840, so just can unload and wait for the next device that sends the execution subsequent step to.Can carry out subsequent step easily like this.

In addition, shown in Figure 51 G, if the cell liquid crystal display panel layer that subsequent step needs to have filter substrate is stacked on the tft array substrate, just in unloading unit 840, insert first roll-over unit 860, send the device of carrying out subsequent step to after the cell liquid crystal display panel upset with unloading.

Therefore, in panel of LCD cutter sweep and method thereof according to one embodiment of the invention, first and second line are once rotated by execution simultaneously on first and second substrates and twice line forms, and according to the method for exerting pressure with first and second cylinders first and second substrate cut are become the cell liquid crystal display panel then at least one position of first and second line.

Simultaneously, have the tft array that is bonded to face-to-face together and the cell liquid crystal display panel of color filter array substrate and be mounted on first and second substrates, staying uniform distance to each other.And outer the placing that does not have the cell liquid crystal display panel on first and second substrates forms virtual sealant, prevents to be bonded to together first and second base plate deformations according to liquid crystal display modes.

If adopt embodiments of the invention to cut first and second substrates that formed virtual

UV curing sealant

40 and 50 in the above, first and second substrates of cutting may be difficult to be separated from each other.

Figure 52 represents to have formed first and second substrates of virtual UV curing sealant above can effectively cutting and be separated in according to a kind of panel of LCD cutter sweep of another embodiment of the present invention and the schematic block diagram of method thereof.

Referring to Figure 52, comprise that according to the cutter sweep of another embodiment of the present invention load units 900 is equipped with first and second substrates of a plurality of cell liquid crystal display panels above loading and being aligned in, first scribing unit 910, it keeps first and second substrates with suction, first and second substrates are loaded between first and second table tops, stay predetermined distance to each other, and on first, lower whorl forms first line on first and second substrate surfaces, cut first and second substrates by on direction away from each other, moving first and second table tops, first rotary unit 920, the first and second substrate half-twists with cutting, second scribing unit 930, keep having rotated 90 ° first and second substrates with suction, first and second substrates are loaded between third and fourth table top, stay predetermined distance to each other, and on second, lower whorl forms second line on first and second substrate surfaces, cut first and second substrates by on direction away from each other, moving third and fourth table top, and unloading unit 940, be used for unloading by the cell liquid crystal display panels of first and

second scribing units

910 and 930 cuttings, the cell liquid crystal display panel sent to the device of carrying out next procedure.

Figure 53 A is illustrated in the concrete synoptic diagram of the subsequent step of carrying out in each frame of Figure 52 to 53G.Below to explain in detail according to panel of LCD cutter sweep of the present invention and method thereof.

Referring to Figure 53 A, tft array substrate and color filter array substrate are formed on first and second substrates of face-to-face bonding.In load units 900, first and

second substrates

10 and 20 of bonding are loaded onto on first table top 905, aim at alignment mark 906 then.

In this case, above first and

second substrates

10 and 20 are loaded in, top first substrate 10 that has formed tft array substrate is laminated on second substrate 20 that has formed color filter array substrate in the above.Compare with the situation that first and second substrate overturns are stacked, can slow down the vibration that in the cutting process of first and

second substrates

10 and 20, affacts on tft array substrate and the filter substrate.

Referring to Figure 53 B, in first scribing unit 910, first and

second substrates

10 and 20 are loaded in across in the space between first table top and second table top 911, keep at a distance with first table top 905, and the suction adsorption by inhaling hole 912 in the above then.And take turns 913 and 914 by first and second in the space that stays between first and second table tops 905 and 911 and on first and

second substrates

10 and 20 surfaces, form first line 915 and 916 in order respectively.

Because grid and data pads are left sides that is respectively formed at tft array substrate, one side of right and last, one side of following direction, a side that is formed on the tft array substrate on first substrate 10 is than corresponding one side-prominent on the filter substrate that is formed on second substrate 20.

In this case, wheel 913 and the interior reference line R1 one side reservation distance in tft array substrate (first substrate 10) district on first, this side is more side-prominent than color filter array substrate (second substrate 20) last corresponding, thereby forms first line 915 on the surface of first substrate 10.And first lower whorl 914 and reference line R1 reservation distance at a distance of preset distance, rule 916 thereby form first on the surface of second substrate 20 on the opposite direction of wheel 913 on corresponding first.

Simultaneously, on first, lower whorl 913 and 914 does not form in the zone of first substrate 10 of the grid of tft array substrate or data pads (just tft array substrate is not from the outstanding zone of color filter array substrate) in the above and aims at each other as to identically, and formation first rules 915 and 916 on the surface of first and

second substrates

10 and 20 respectively.

Referring to Figure 53 C, on direction away from each other, move with first and second table tops 905 and 911 of inhaling hole 912 stickings, first and

second substrates

second substrates

10 and 20 are cut.

On first and second table tops 905 of sticking first and

second substrates

10 and 20 and 911 surfaces, form and inhale hole 912, inhale and keep equidistant between the hole.It is air-breathing to inhale hole 912, with suction with first and

second substrates

10 and 20 stickings on first and second table tops 905 and 911.Like this, first and

second substrates

10 and 20 just can not wave.Transmitting first and second substrates 10 that cut and being blown into air at 20 o'clock, unload first and

second substrates

10 and 20 from first and second table tops 905 and 911.

Simultaneously, shown in Figure 54, the suction hole 912 of formation has the sticking portion 1012 of homalographic, so more effectively sticking first and second substrates on first and second table tops 1005 and 1011 surfaces.Can also prevent from addition to inhale the hole forms black stain on first and

second substrates

10 and 20 possibility because of pressure of inspiration(Pi) is provided with too high making.

Referring to Figure 53 D, first and second substrates 10 that cut and 20 are rotated 90 ° in first rotary unit 920.

Referring to Figure 53 E, in second scribing unit 930, first and

second substrates

10 and 20 of rotation are loaded onto across in the space between third and

fourth table top

931 and 932, stay uniform distance to each other, and with inhaling hole 933 stickings.Then with on second in the separate space between third and

fourth table top

931 and 932,

lower whorl

934 and 935 forms

second line

936 and 937 successively on first and

second substrates

10 and 20 surfaces.

Described as reference Figure 53 B, in a side of tft array substrate on than filter substrate in corresponding one side-prominent that zone, on first, lower whorl 913 and 914, on second,

lower whorl

934 and 935 is leaving the predetermined distance of mutual maintenance on the direction opposite each other of reference line R1, thereby forms

second line

936 and 937 on first and

second substrates

10 and 20 surfaces.And not from color filter array substrate in the outstanding zone, on second,

lower whorl

934 and 935 is aimed at identically each other at tft array substrate, thereby formation second rules 936 and 937 on the surface of first and

second substrates

10 and 20.

Referring to Figure 53 F, in second scribing unit 930, on direction away from each other, move with third and

fourth table top

931 and 932 of inhaling hole 933 stickings, first and

second substrates

10 and 20 along

second line

936 and 937, first and

second substrates

10 and 20 are cut.

The suction hole 912 that forms on the suction hole 933 that forms on third and

fourth table top

931 and 932 surfaces and first and second table tops 905 and 911 is identical, all forms same sticking portion 1012 as shown in figure 43, has predetermined area separately.

Referring to Figure 53 G, unloading unit 940 will send the device of carrying out subsequent step to along first and second line 915,916, the 936 and 937 cell liquid crystal display panel of cutting successively.

State when being sent to load units 900 with panel of LCD is compared, and shown in Figure 53 G, Qie Ge cell liquid crystal display panel has been turned over 90 ° in order.The cell liquid crystal display panel has been turned over 90 ° because of insert second rotary unit 950 in unloading unit 940, so just can unload and wait for the next device that sends the execution subsequent step to.Can carry out subsequent step easily like this.

In addition, shown in Figure 53 G, if the cell liquid crystal display panel layer that subsequent step needs to have filter substrate is stacked on the tft array substrate, just in unloading unit 940, insert first roll-over unit 960, send the device of carrying out subsequent step to after the cell liquid crystal display panel upset with unloading.

Therefore, in panel of LCD cutter sweep and method thereof according to another embodiment of the present invention, first and second line are once rotated by execution simultaneously on first and second substrates and twice line forms, according to the first/the second table top sticking with loading first and second substrates, the mode that the 3rd/the 4th table top moves on direction away from each other becomes the cell liquid crystal display panel with first and second substrate cut then.

According to the method described above, the substrate with a plurality of unit panels is cut into unit panel.On each panel, carry out grinding steps then.

Figure 58 represents the synoptic diagram according to the amount of grinding test pattern of the panel of LCD of one embodiment of the invention, and Figure 59 represents the synoptic diagram according to the amount of grinding test pattern of the panel of LCD of another embodiment of the present invention.

Referring to Figure 58, cell liquid crystal display panel 350 comprises the image-display units 313 that has by the liquid crystal cells of matrix arrangement, gate lines G L～the GLm of image-display units 313 is connected to gate drivers integrated circuit (not shown in FIG.) provides the gate pads 314 of signal, the data line DL～DLn of image-display units 313 is connected to data driver integrated circuit (not shown in FIG.) provides data of image information pad 315 for it for it.In this case, grid and

data pads

314 and 315 are formed on the neighboring area of first substrate 10, and the minor face of substrate 10 and long limit are outstanding from second substrate 20.

In each zone that data line DL～DLn and gate lines G L～GLm intersect; although not expression among the figure; comprise a thin film transistor (TFT); be used for switching formed corresponding liquid crystal cell; a pixel electrode; with a passivation layer that on whole surface, forms, be used for protected data line DL～DLn, gate lines G L～GLm thin film transistor (TFT) and electrode.

In addition, as mentioned above, form such as data line DL～DLn the static that might produce during conductive layers such as gate lines G L～GLm and electrode on first substrate 10 in order to be breaking at, position, an edge at first substrate 10 forms the short-circuit conductors (not shown), with the conductive layer electric short circuit.

On second substrate 20 of image-display units 313, form a plurality of coating color filters of isolating mutually with black matrix layer, and on first substrate 10, form common electrode as the counter electrode of corresponding pixel electrode by the box zone.

As mentioned above, between first and

second substrates

10 and 20 that face with each other, keep uniform distance by the box gap, bonded to one another with the sealant (not shown in FIG.) that is formed on image-display units 313 edges, and form liquid crystal layer in the insulating space between first and

second substrates

10 and 20.

Simultaneously, on grid and

data pads

314 and 315, form separately quantity consistent beat mark 355A～355J, accurately aim at from data line DL～DLn gate lines G L～GLm, the contact plug of extracting out on grid and the data driver integrated circuit.For example shown in Figure 58, on gate pads 314, form three separately and beat mark 355A～355C, and mark 355D～355J is beaten in seven of independent formation on data pads 315.

An edge of said units panel of LCD 350 should tilt to be ground to abrasive wire R1 from cell liquid crystal display panel 350 1 end END1.Yet shown in the amplification region EX1 among Figure 58, the actual abrasive wire and the abrasive wire R1 of cell liquid crystal display panel 350 have predetermined error range, if this error has departed from the error surplus D1 that allows, just are judged as the grinding fault, and D1 approximately is 200 μ m.

The user extracts the cell liquid crystal display panel 350 that grinds by the cycle from line, send the panel 350 that extracts to other measurement mechanism, and with the camera of high-amplification-factor, whether the actual abrasive wire of projector or the like judging unit panel of LCD 350 has departed from the error surplus D1 that allows.

According to one embodiment of the present of invention, shown in Figure 58, be that the benchmark correspondence an amount of grinding identification of the error surplus D1 formation figure 360 that allows with abrasive wire R1.In this case, the error surplus D1 of permission is set at ± 100 μ m.In addition, if on gate pads 314, form amount of grinding identification figure 360, should when forming gate lines G L1～GLm, form amount of grinding identification figure 360.And,, should when forming data line DL1～DLn, form amount of grinding identification figure 360 if on data pads 315, form amount of grinding identification figure 360.

So just can come the actual abrasive wire of judging unit panel of LCD 350 whether to depart from the error surplus D1 that allows by observation amount of grinding identification figure 360.

Be exactly the amount of grinding identification figure 360 of observing the cell liquid crystal display panel 350 that has ground specifically, if amount of grinding identification figure 360 just is judged to be the fault of ' grinding not enough ' or ' overgrinding ' because of not grinding fully or grinding fully and can't discern.

Judge that according to this panel of LCD amount of grinding test pattern of one embodiment of the invention with this figure the method for grinding fault can be by the grinding fault of observing amount of grinding identification figure 360 come the judging unit panel of LCD, thereby do not need extra measurement mechanism, and can judge the grinding fault of all cell liquid crystal display panels 350.

Figure 59 represents the synoptic diagram according to the amount of grinding test pattern of the panel of LCD of another embodiment of the present invention.

Referring to Figure 59, cell liquid crystal display panel 350 comprises the image-display units 313 that has by the liquid crystal cell of matrix arrangement, gate lines G L～the GLm of image-display units 313 is connected to gate drivers integrated circuit (not shown in FIG.) provides the gate pads 314 of signal, the data line DL～DLn of image-display units 313 is connected to the data driver integrated circuit provides data of image information pad 315 for it for it.In this case, grid and

data pads

Simultaneously, on grid and

data pads

314 and 315, form separately quantity consistent beat mark 355A～355J, accurately aim at from data line DL～DLn gate lines G L～GLm, the contact plug of extracting out on grid and the data driver integrated circuit.For example shown in Figure 59, on gate pads 314, form three independently of one another and beat mark 355A～355C, and on data pads 315, form seven independently of one another and beat mark 355D～355J.

An edge of said units panel of LCD 350 should tilt to be ground to abrasive wire R1 from cell liquid crystal display panel 350 1 end END1.Yet shown in the amplification region EX1 among Figure 59, the actual abrasive wire and the abrasive wire R1 of cell liquid crystal display panel 350 have predetermined error range, if this error has departed from the extent of the error D1 that allows, just are judged as the grinding fault.

According to an alternative embodiment of the invention, being benchmark with abrasive wire R1 forms equally spaced to each other amount of grinding identification figure 360a～360o on correspondence the zone of the error surplus D1 that allows.

Amount of grinding identification figure 360a～360o preferably forms like this, and the distance that will be arranged on about 100 μ m from abrasive wire R1 to permissible error surplus D1 is divided into the even unit that can with the naked eye discern.

For example shown in Figure 59, if form three equally spaced amount of grinding identification figure 360g～360i at the middle part, a zone on cell liquid crystal display panel end END1 direction just can be from being that the zone of beaing on the mark 355JI direction of a line formation coincideing mutually of border is distinguished with abrasive wire R1.

And, form the zoning of discerning figure 360b～360f more near the amount of grinding that beats mark 355J by equidistant unit, discern the edge of figure 360g～360i one sides more near three amount of grinding of middle part.And form the amount of grinding identification figure 360a identical with amount of grinding identification figure 360b at ragged edge.

In addition, form the zoning of discerning figure 360j～360n more near the amount of grinding of cell liquid crystal display panel end END1, the edge of three amount of grinding identification figure 360g～360i one sides of close more middle part by equidistant unit.And form the amount of grinding identification figure 360o identical with amount of grinding identification figure 360n at ragged edge.

The amount of grinding identification figure 360a and the 360o that are formed on ragged edge can guarantee to grind fault judgement very reliably, and whether three amount of grinding identification figure 360g～360i of middle part help the actual abrasive wire of judging unit panel of LCD 350 to coincide with abrasive wire R1.

Beat in formation on the edge in that zone of mark 355J and be marked with numeral (10 ,-8 ,-6 ,-4 ,-2,0,2,4,6,8,10), corresponding amount of grinding identification figure 360a～360o.Actual amount of grinding that so can detecting unit panel of LCD 350.In this case, suppose to be ± 100 μ m that the unit of numeral (10 ,-8 ,-6 ,-4 ,-2,0,2,4,6,8,10) is exactly 10 μ m from the permissible error surplus D1 of line of cut R1.

So just can be by realize whether the actual abrasive wire of cell liquid crystal display panel 350 being departed from the judgement of permissible error surplus D1 with visual inspection amount of grinding identification figure 360 according to another embodiment of the present invention.

Specifically, observe the amount of grinding identification figure 360a～360o of the cell liquid crystal display panel 350 that has ground, if can't see the amount of grinding identification figure 360a and the 360b on a side edge, just be judged to be the fault that ' overgrinding ' causes, if amount of grinding identification figure 360n and 360o are not ground off fully, just be judged as the fault that ' grinding not enough ' causes.

In addition, in another embodiment of the present invention, can come the actual abrasive wire and the line of cut R1 of inspection unit panel of LCD 350 by visual inspection, and can discern the numeral (10 ,-8 ,-6 of figure 360a～360o by the camera inspection correspondence amount of grinding of high-amplification-factor,-4 ,-2,0,2,4,6,8,10), thus the actual abrasive wire of detecting unit panel of LCD 350 whether in 20 μ m error ranges.

Simultaneously, form more amount of grinding identification figure and can make the zoning of amount of grinding identification figure thinner, the error range that so just can dwindle 20 μ m.

If for various reasons for line of cut R1 adopt ± 100 μ m permissible error surplus D1 are set to 80 μ m, one embodiment of the present of invention will be unable to cope with this variation.Yet in another embodiment of the present invention, the numeral (10 ,-8 ,-6 ,-4 ,-2,0,2,4,6,8,10) of corresponding amount of grinding identification figure 360a～360o is to check by the camera of high-amplification-factor, therefore can deal with this variation.

After finishing grinding steps S17, check each cell liquid crystal display panel (S18).
