Description

Display control unit, check system, display control method, program and the recording medium that records the embodied on computer readable of this program

Technical field

The present invention relates to display control unit etc., especially, by lighting the mode of the display device that includes display panels, Plasmia indicating panel, EL display panel etc., the display control unit that this display device is carried out defect inspection.

Background technology

Owing to use the flat-panel monitor of display panels etc. to have characteristics such as light weight, slim, low power consumption, therefore be applicable in the every field, especially, be widely used as the display of household appliances and information terminal device.

In the production scene of this type of flat-panel monitor, by in each operation, carrying out the electrical action inspection, adopting the panel of the mode light panel to light the quality that various inspections such as inspection come management product.

Carry out above-mentioned panel and light when checking, the existence of judging line defects such as point defects such as bright spot or stain, bright line or black line, the unequal defective of panel by the actual mode of lighting panel whether.Specifically be,, all preestablish and be used on the display mode of checking this defective at every kind of defective, that is, and ignition mode.Checked zero defect by showing this ignition mode successively.

Lighting in the inspection in the prior art, employing be by the overlooker aforesaid ignition mode to be carried out naked eyes to confirm to have checked flawless visual check.But visual check exists check result problems such as deviation, inspectoral processing power be uneven to occur because of inspectoral individual differences.

Therefore, now, use the situation of the automatic checking device of lighting inspection automatically gradually many.By using automatic checking device, can solve the judged result that exists in the visual check or processing power etc. the problem of deviation to occur, and can light inspection rapidly.Automatic checking device can check according to certain judgment standard, therefore, is particularly useful in the inspection that checkpoint defective or line defect etc. can quantize to judgment standard.

But, be not the inspection that automatic checking device is not suitable for the defective of checking that the unequal degree that is difficult to defective quantizes.In addition, whether just often to check the limit brightness value that can confirm by naked eyes, therefore can the problem that also exists judgment standard confirm by naked eyes, be difficult to set judgment standard.In such cases, general in order to prevent the defective product of omission in lighting inspection all to the higher inspection sensitivity of automatic checking device setting, thus can detect judgment standard with respect to visual check superfluously.

That is, automatic checking device has its strong point and weakness according to the difference of inspection item.Therefore, for the part that only depends on automatic checking device fully not check, be necessary to replenish by visual check of the prior art.That is, preferred mode is to use automatic checking device to check after one time earlier, again the test mode of finally confirming by visual check.

With an automatic checking device and a macroscopic example, disclosed a kind of defect inspecting system as also in the patent documentation 1.In the defect inspecting system of patent documentation 1, pass through automatic checking device, judge that based on the view data of liquid crystal panel this liquid crystal panel is whether in the reference range of regulation, carry out visual check according to the view data that is judged to be outside benchmark then, and liquid crystal panel is made final good and bad judgement.

In addition, can enumerate patent documentation 2 as other example.According to patent documentation 2, recording defect position when carrying out self-verifying, and by notifying the defective locations that is write down to save the macroscopic time to carrying out macroscopic overlooker.

As mentioned above, light when checking, in order to detect defective reliably,, also need to carry out visual check except utilizing automatic checking device checks.But, if carry out self-verifying and visual check both sides, the problem that the supervision time prolongs can appear.

Particularly, in the prior art, carry out self-verifying and visual check both sides' words, at first, on automatic checking device, show successively at every kind of ready ignition mode of defective, and confirm to have or not various defectives, then, when carrying out visual check, show successively that more above-mentioned ignition mode is to confirm to have or not various defectives.

At this, being judged as flawless ignition mode by automatic checking device is to be confirmed as flawless ignition mode, therefore, need not this is carried out visual check.That is, light inspection, when carrying out visual check, also show again for need not to carry out macroscopic ignition mode, thereby cause waste according to of the prior art.

Owing in visual check, shown the ignition mode that need not to check, therefore can cause many problems.For example, when shown was the ignition mode that need not to check, the ignition mode that the overlooker will make this demonstration was the judgement that automatic checking device has been confirmed as flawless ignition mode, and can make device show next ignition mode, therefore, also need to switch the unnecessary processing of ignition mode.

And, demonstrate under the situation of the ignition mode that need not to check, the overlooker need not to check the judgement of the ignition mode that is shown, the operation of switching and showing next ignition mode during can't check, therefore can cause temporal waste.

And when carrying out visual check, the overlooker checks according to the order of the ignition mode of continuous demonstration, therefore, may also carry out visual check to the ignition mode that need not reexamine sometimes.Can further cause the waste of supervision time in this case.

As mentioned above, lighting in the inspection in the prior art can be presented at the ignition mode of not finding defective in the self-verifying when carrying out visual check once more, thereby causes elongated problem of supervision time.

Summary of the invention

The present invention develops in view of the above problems, display control unit that provides the supervision time that can shorten check system etc. is provided its purpose, the check system that the present invention relates to is meant, at the display defect of the display device that goes out by the 1st inspection process inspection, check the system that checks once more in the operation the 2nd.

To achieve these goals, the invention provides a kind of display control method, when checking the display defect of display device at a plurality of inspection items, for checking in the operation by showing that successively a plurality of the 1st ignition mode are judged the display device that each inspection item has or not display defect the 1st, check in the operation the 2nd, make this display device show the 2nd ignition mode that is used to check the inspection item identical with above-mentioned the 1st operation, this display control method is characterized in that comprising: show the control operation, carrying out the above-mentioned the 2nd when checking operation, from display object, removing and be used for checking the above-mentioned the 1st and check that operation is judged as the 2nd ignition mode of the inspection item of no display defect.

In addition, to achieve these goals, the invention provides a kind of check system, it is characterized in that comprising: the 1st testing fixture, be used to carry out the 1st and check operation, promptly by showing that successively a plurality of the 1st ignition mode judge that each project in a plurality of inspection items has or not display defect; The 2nd testing fixture is used to carry out the 2nd and checks operation, promptly is used to check with the above-mentioned the 1st check that the 2nd ignition mode judgement of the inspection item that operation is identical has or not display defect; Display control unit comprises display control unit, and this display control unit is used for removing from the display object of above-mentioned the 2nd display device and is used to check the 2nd ignition mode that is judged as the inspection item of no display defect by above-mentioned the 1st testing fixture.

According to said structure, check in the operation the 2nd, do not show to be used for checking the 1st and to check that inspection item that operation is judged as no display defect promptly need not to carry out the 2nd ignition mode of the inspection item that display defect judges again.

Therefore, can reduce the number of the 2nd shown in the 2nd inspection operation ignition mode, it is less than the 1st check the number of the 1st shown in operation ignition mode, thereby can shorten the supervision time of the 2nd inspection operation.And, according to said structure, can avoid checking the waste that is caused because of use need not to carry out the 2nd ignition mode that display defect judges again.

The so-called the above-mentioned the 1st checks operation and the 2nd inspection operation, for example, it can be the inspection operation of utilizing automatically the automatic checking device that display defect is checked, also can be to utilize the visual check device that on display device, shows ignition mode successively, and the ignition mode that is presented at successively on the display device by this visual check device is estimated by the overlooker, checking the inspection operation that has or not display defect with this, perhaps also can be both combinations.In addition, above-mentioned automatic checking device and visual check device can be made of 1 device, also can be formed by the multiple arrangement combination.

In addition, the number of the 2nd ignition mode of removing from display object is 1 and checks that the 2nd the number of the 2nd shown in operation ignition mode can reduce when above, therefore can shorten for the 2nd supervision time of checking operation.

That is, above-mentioned display control unit might not be removed the processing of the 2nd ignition mode to all inspection items that is judged as no display defect.For example, existing especially needs display defect that emphasis judges or checks under the situation of the display defect that is difficult to make judgement in the operation the 1st, regardless of the judged result of the 1st inspection operation, can check the 2nd to show the 2nd ignition mode that is used to check this display defect on the operation.

In addition, above-mentioned display device is not particularly limited, as long as can in its display frame, have a plurality of pixels, and by each pixel being become light or non-illuminating state comes the device of display image to get final product.For example can use liquid crystal indicator, plasma display system, EL display device and cathode tube display device etc. as above-mentioned display device.

In addition, though above-mentioned the 1st ignition mode all is used to check identical inspection item with the 2nd ignition mode, be used in the ignition mode in the different inspection operations respectively.Therefore,, identical ignition mode can be used, also different ignition mode can be used as above-mentioned the 1st ignition mode and the 2nd ignition mode.

For example, the 1st checks that operation is, the display device under the state that shows the 1st ignition mode is taken, and analyze taking the image that obtains, and check the self-verifying operation of display defect with this; The 2nd checks that operation is, by the user (for example carrying out macroscopic overlooker) of display control unit the display device under the state that shows the 2nd ignition mode is estimated, and is checked the visual check operation of display defect with this.In this case, employing is adapted to pass through the ignition mode that display defect is checked in graphical analysis as the 1st ignition mode, adopts as the 2nd ignition mode to be adapted to pass through the ignition mode that naked eyes are checked display defect.

In addition, though also use the check system of coming display device is carried out defect inspection by two inspection operations of the 1st inspection operation and the 2nd inspection operation in the prior art, but in the present invention, the preferred employing by the 2nd checked the structure that operation reexamines the inspection item that is detected display defect in the 1st inspection operation.

For example,, check the inspection item of not finding display defect in the operation the 1st, check that the 2nd operation reexamines for some according to 2 check systems of checking that operation is carried out defect inspection to display device of the prior art.According to this existing check system, in the 1st inspection operation, detected under the situation of display defect, check that the 1st the operation stage just is judged as defective products as the display device of checking object.Therefore,, also can be judged as defective products, repair in the operation or go out of use and be transferred to even some display device only comprise the display defect that is unlikely to constitute the product quality problem.

To this, according to structure of the present invention, for checking the inspection item that is detected display defect in the operation, check in the operation and can reexamine the 2nd, thereby can only detect reliably the display device that comprises the display defect that causes the product quality problem the 1st.

In addition, preferred, check in the operation the above-mentioned the 1st, display defect is carried out the surplus inspection.In other words, in above-mentioned the 1st operation, except clearly judging the inspection item that has display defect, there is the inspection item of display defect in suspection, also makes the judgement that has display defect.

For example, the difference of the brightness value of the pixel when showing the 2nd ignition mode on the brightness value of the pixel when showing the 2nd ignition mode on as the display device of checking object and the normal display device at no display defect is judged on the above-mentioned pixel to have display defect during greater than the threshold value stipulated in advance.

In this example, the difference that can judge above-mentioned brightness value is big more, and that the possibility of display defect then takes place is higher.Therefore, by being the threshold value less than existing general inspection device with above-mentioned threshold setting, the pixel that is suspected to have display defect also can be judged out and have display defect.That is, preferred, can be judged as in the range of luminance values of no display defect even the difference of above-mentioned brightness value belongs to by existing general inspection device, but in this example, understand the judgement that make display defect to above-mentioned brightness value.

According to said structure,,, also check that by the 2nd operation reexamines for the inspection item that may have display defect except to can clearly being judged as the inspection item that has display defect.That is,, will carry out 2 times and check for being difficult to judge the inspection item that has or not display defect or may have display defect.Therefore, can detect certain in-problem display defect reliably.

In addition, the 2nd checks that operation is under the macroscopic situation, checks in the operation the 2nd, when showing that the 2nd luminance patterns is judged display defect on display device, can distinguish the pixel that obviously there is the pixel of display defect in demonstration and may has display defect.Thus, the user of display control unit (carrying out macroscopic overlooker) can have or not the pixel of problems such as display defect to check emphatically to existing to be difficult to judge.

It is very clear that other purposes of the present invention, feature and advantage can become in the following description.Below, come clear and definite advantage of the present invention with reference to accompanying drawing.

In check system 1, to each pixel of being examined panel P light and whether non-illuminating state is normally checked.That is, if be examined panel P each pixel light and non-illuminating state undesired, just judge that being examined panel P exists defective (display defect).Being examined the defective that may occur on the panel P has multiplely, by being examined on the panel ignition mode that shows the regulation that is used to detect various defectives, can check that being examined panel has zero defect.About the kind of defective and the relation between the ignition mode, will be described hereinafter.

As shown in Figure 1, comprise automatic checking device 3 in the self-verifying operation, comprise display control unit 4 and panel lamp device 5 in the visual check operation.3 pairs of automatic checking devices are examined panel P has zero defect to judge automatically, that is, and and self-verifying, and this self-verifying result exported to data storage device 2.The detailed content of relevant automatic checking device 3 will be described hereinafter.

Display control unit 4 reads the self-verifying result from data storage device 2, then according to the self-verifying result who reads, and the DISPLAY ORDER of decision ignition mode, and, on panel lamp device 5, show ignition mode according to the DISPLAY ORDER that determines.Display control unit 4 comprises check result obtaining section 6, display control unit 7, display part (alternative pattern display part) 9 and input part 8.

Check result obtaining section 6 is interface portion of display control unit 4, is used for reading the self-verifying result from data storage device 2, and the self-verifying result who reads is sent to display control unit 7.Be not particularly limited for check result obtaining section 6, can connect data storage device 2 by wired or wireless mode, and the function that can obtain the self-verifying result from data storage device 2 gets final product as long as have.

Display control unit 7 receiving checks are the obtained self-verifying result of obtaining section 6 as a result, and according to the self-verifying result who receives, the DISPLAY ORDER of decision ignition mode according to the DISPLAY ORDER of this decision, sends the demonstration indication of each ignition mode then to panel lamp device 5.The detailed content of relevant display control unit 7 will be described hereinafter.

The user that input part 8 is used to receive display control unit 4 promptly carries out the input of the action indication that macroscopic overlooker carries out display control unit 4.That is, carry out macroscopic overlooker, can make display control unit 4 carry out desirable action by operation inputting part 8.As long as input part 8 can receive the input of the action indication of being undertaken by described overlooker, can use known input medias such as keyboard, button, mouse.

At this, suppose that input part 8 has respectively with each of display control unit 4 to move corresponding load button (not shown).And, suppose that input part 8 receives the operation of pushing load button that described overlookers carry out after, carry out and the corresponding actions of this load button by display control unit 4.The action that the operation of according to the overlooker input part 8 being carried out about display control unit 4 is carried out will be described hereinafter.

Display part 9 demonstrations are used for auxiliary macroscopic supplementary.As long as the overlooker of operation inspection system 1 can recognize the supplementary that is displayed on the display part 9 by naked eyes, then display part 9 is not particularly limited.For example, can use CRT display device, liquid crystal indicator and EL display device etc. as display part 9.About supplementary, will be described hereinafter.

That is to say that display control unit 4 moves by the action indication of input part 8 inputs according to carrying out macroscopic overlooker.Then, check result obtaining section 6 obtains after the self-verifying result, display control unit 7 decides the DISPLAY ORDER of ignition mode according to the self-verifying result, and sends indication to panel lamp device 5, makes that the DISPLAY ORDER according to decision shows ignition mode on the panel P being examined.

Panel lamp device 5 will be presented at by display control unit 4 indicated ignition mode and be examined on the panel P.Particularly, panel lamp device 5 with wired or wireless mode be examined panel P and be connected, panel lamp device 5 receives ignition mode and shows after the indication from display control unit 4, send the control signal of lighting that is used for being examined at this indicated ignition mode of demonstration on panel P to being examined panel P.

Thus, ignition mode will be shown to according to the DISPLAY ORDER that is determined by display control unit 4 and be examined on the panel P.About detailed content, will be described hereinafter.In check system 1, control the demonstration of ignition mode by display control unit 4 according to the self-verifying result, thereby can shorten the supervision time of visual check operation.

(self-verifying operation)

As mentioned above, being examined the defective that may occur on the panel P has multiplely, in order to detect various defectives, is necessary to show the various ignition mode that are prescribed being examined on the panel.In check system,, set inspection item at every kind of defective in order to have or not the inspection of above-mentioned number of drawbacks.In each inspection item, by showing that the various ignition mode that are prescribed have checked zero defect being examined on the panel P.When in the total inspection project, all confirming not have defective, can judge to be examined the satisfied stipulated standard of panel P as product.

In the self-verifying operation, automatically to being examined the inspection that panel P carries out above-mentioned each inspection item, that is, carry out self-verifying by automatic checking device 3.Next, with reference to Fig. 2, automatic checking device 3 is elaborated.Fig. 2 is the stereographic map of the brief configuration of expression automatic checking device 3.

As shown in Figure 2, automatic checking device 3 comprises travelling belt 11, filming apparatus 12, base station 13 and image processing apparatus 14.Automatic checking device 3 connects these component parts by wired or wireless mode, and possesses the not shown automatic checking device control part that is used for above-mentioned component parts is all together control, thus, can detect to be examined on the panel P has zero defect, and check result is stored in the memory storage 2.

Next, the action of automatic checking device 3 is described.In automatic checking device 3, at first send indication to travelling belt 11 by the automatic checking device control part, will be examined the shooting area of panel P conveyance to filming apparatus 12.Be examined after the shooting area of panel P arrival filming apparatus 12, just stop the transmission of travelling belt 11.In addition, detected panel P is that it shows that the display surface of ignition mode and the shooting face of filming apparatus 12 are arranged on the travelling belt 11 abreast.Then, under the display surface that keeps the being examined panel P state parallel with the shooting face of filming apparatus 12, travelling belt 11 conveyances are examined panel P.Only show among Fig. 21 situation that is examined panel P is set, certainly, be examined after the inspection that panel P carries out the total inspection project this figure is shown, travelling belt 11 conveyance again comes the next one to be examined panel.That is, in automatic checking device 3, can carry out defect inspection successively and automatically to a plurality of panel P that are examined.

Next, the automatic checking device control part is by using not shown panel lamp device, be examined the ignition mode that shows regulation on the panel P successively, and sending indication, it is taken respectively being presented at the ignition mode that is examined on the panel successively to filming apparatus 12.Filming apparatus 12 will be taken the image that obtains and send to image processing apparatus 14.At this, the ignition mode of regulation is meant, is used to check that each inspection item has flawless ignition mode.

In image processing apparatus 14, the image that is examined panel P that shows each ignition mode is resolved respectively, and zero defect is arranged at each inspection item inspection.Then, image processing apparatus 14 is stored in the check result of each inspection item in the memory storage 2.

At this, image processing apparatus 14 is judged when zero defect is arranged according to the brightness value that is examined the image of panel P, checks in wider scope,, will suspect that the pixel of defective brightness value is also as defect pixel that is.

That is, in the present invention, check in the operation (the self-verifying operation in the present embodiment), defective is carried out the surplus inspection the 1st.In other words, when setting the judgment standard of defective, make it satisfy following condition, that is,, also include a part of good product checking that by the 1st operation is judged as defective being examined among the panel P.

This is because in fact also having some defectives to cause being difficult to detected product is the good product or the judgement of defective products.Thereby, will check that the panel P that is examined that operation is difficult to make judgement delivers to the 2nd as defective products and checks in the operation by the 1st.Then, by the 2nd inspection operation (the visual check operation of present embodiment), whether the above-mentioned panel P that is examined is existed the bad final judgement of carrying out.Thus, check in the operation, can shorten the needed time when being good product or defective products of judging, and can prevent from defective products judged into good product and cause the defective panel P that is examined to take place as the phenomenon of product turnout the 1st.

At this, illustrate the establishing method of the judgment standard when the 1st checks that carrying out the defective surplus in the operation checks.For example, in the present embodiment, suppose to check that the 1st use automatic checking device 3 carries out self-verifying in the operation.In this case, be benchmark with the value that can detect bad limit defective, the deviation of the inspection precision that downward modulation image processing apparatus 14 is had, i.e. the corresponding value that detects repeatability of downward modulation gets final product.In addition, bad limit defective is meant, is checking that by the 1st operation is judged as in the bad defective defective that defective intensity is minimum.

For example, the defective intensity of bad limit defective is C0, detects repeatability under the situation of δ C that the setting value C of judgment standard satisfies C=C0-δ C and gets final product.Wherein, C is the index of expression defective intensity, can suitably adopt and the corresponding index of the kind of defective.Particularly, can use brightness value and GTG value etc. as These parameters.And, for the value of C, C0, δ C, can adopt positive number arbitrarily according to the factors such as kind of defective.

In addition, can be multiplied by coefficient k (k is a positive number), make the setting value C of judgment standard become C=C0-δ C * k checking repeated δ C.In addition, when the value of k increased, the setting value C of judgment standard can reduce, and therefore, had being examined panel P and will being judged as defective products and delivering to the 2nd and check in the operation of the lower defective candidate of defective intensity.Thereby, under the situation that has increased the k value, check that the 2nd the good product that need to check in the operation also can increase, therefore, check the reverse side that the danger that in the operation defective products mistake is judged as good product can reduce the 1st, can prolong for the 2nd supervision time of checking operation.Therefore, during the value of decision k, preferably can consider defective occurrence rate and supervision time.

The filming apparatus 12 that automatic checking device 3 is possessed can be that regional induction type also can be the line induction type.But, under the situation of the filming apparatus 12 that adopts the line induction type,, must make filming apparatus 12 and be examined panel P to relatively move in order to take the whole display surface that is examined panel P.For example, can on base station 13, be provided with and to make filming apparatus 12 with respect to the parallel mobile mechanism of the display surface that is examined panel P.At this moment, by taking, can photograph the whole display surface that is examined panel P on follow shot device 12 limits, base station 13 top.In addition, can also be on base station 13 establishing shot device 12, and take when utilizing travelling belt 11 conveyances to be examined panel P, can take the whole display surface that is examined panel P thus.

(self-verifying result)

Next, obtain and be stored in self-verifying result in the data memory device 2 with reference to Fig. 3 explanation by automatic checking device 3.Fig. 3 is the figure of expression self-verifying result's a example.As shown in Figure 3, self-verifying result has inspection item and ignition mode, check result, the position of defective and the data structure that the defect pixel color forms corresponding relation.

That is, in automatic checking device 3,6 inspection items by i～vi detect and are examined panel P zero defect is arranged.When all not detecting defective, just judge that this is examined panel P and does not have quality problem as product by 6 inspection items.On the contrary, as long as in 6 inspection items, there is 1 inspection item to detect defective, just judge that this is examined panel P and has quality problem as product.In the following description, will be called defective i～vi by the defective that 6 inspection items of i～vi are checked out.

As shown in Figure 3, each inspection item and ignition mode form corresponding relation.That is, in automatic checking device 3, by be examined on the panel P ignition mode that shows regulation detect each inspection item defective existence whether.For example, in inspection item i, by showing that lighting Mode A has detected zero defect i being examined on the panel P.

In addition, in 1 inspection item, can adopt a plurality of ignition mode to detect zero defect sometimes.For example, inspection item v and 2 kinds of ignition mode promptly form corresponding relation with ignition mode E and F.This expression in order to check defective v, need promptly show ignition mode E and F being examined 2 kinds of ignition mode of demonstration on the panel P.

As utilizing a plurality of ignition mode to detect flawless example, can enumerate the detection of electric leakage (line leak) defective between line.At this, be examined panel P and have the structure that its pixel is arranged in matrix shape, each pixel column is provided with the distribution that is used to light each pixel.Wherein, the electric leakage defective is meant between line, because of leaking electricity between the adjacent distribution, cause with the adjacent pixel that should not light originally of the pixel lighted by the defective of lighting and producing.

In order to check this defective, at first only light the even lines in the distribution that is examined panel P.When leaking electricity defective between the generation line, the pixel of the odd lines that should not light also can be lighted originally.In this stage, just the pixel that should not light has originally been lighted, and therefore, may consider whether to have produced the defective that non-some bright pixel lighted, i.e. fleck defect in addition.

Therefore, next step lights odd lines.When producing between line the electric leakage defective, in the pixel of the even lines that should not light, the adjacent pixel of the pixel of the odd lines of being lighted when only lighting even lines can be lighted.Hence one can see that, taken place to leak electricity between line between the pixel of the pixel of the odd lines of being lighted when lighting even lines and the even lines lighted when lighting odd lines.Certainly, only light the method for even lines afterwards again, also can detect between outlet and leak electricity by only lighting earlier odd lines.

Record the check result of each inspection item among the self-verifying result.In check result one hurdle, shown at the result of each inspection item whether very.In illustrated embodiment, if that show in the result bar of self-verifying is " OK ", is illustrated in this inspection item and does not detect defective, if that show is " NG ", is illustrated in and has detected defective in the inspection item.The example of Fig. 3 has been represented not detect defective in inspection item iii and v, and has detected the state of defective in other inspection item.

And, in the self-verifying result, at the inspection item that detects defective, defective locations and detect between the color of pixel of defective and form corresponding relation.That is, in automatic checking device 3,, will obtain defective in the position that is examined on the panel P if detected defective.And, in automatic checking device 3,, will obtain the color of pixel that is detected defective if detected defective.At this, suppose to be examined panel P and have 3 kinds of color pixel of red, green, blue.

In example shown in Figure 3, shown the coordinate of the pixel that is detected defective in defective locations one hurdle, can specificly fall vacant thus is trapped in the position that is examined on the panel P.Defective locations is, carries out that macroscopic overlooker is convenient to the position of specific defects and the information used in order to make, therefore, as long as can roughly represent to be examined defective and the position thereof of panel P.For example, can be divided into a plurality of zones, and express the existing zone of defective and get final product being examined panel P.

In example shown in Figure 3, with a coordinate representation position of each defective.Certainly, line defect for example, detected defective is sometimes across a plurality of pixels.In this case, can in one hurdle, detection position, write down the mathematical expression etc. of expression defect coordinate scope.That is, defective locations can be that expression detects the position of defective or the data of scope.

In addition, the defect pixel color is, carries out that macroscopic overlooker is convenient to find defective and the information utilized in order to make.That is,, just can carry out visual check emphatically, thereby can more easily find defective this color if the overlooker has grasped the color of defect pixel in advance.Automatic checking device 3 will be obtained the color of pixel that fleck defect has taken place when having detected defectives such as fleck defect.For example, be examined on the panel P, the specific pixel that only has that occur to constitute in the pixel that is examined panel P becomes under the situation of fleck defect of bright spot all the time, and automatic checking device 3 is according to the locations of pixels that fleck defect takes place, and can be specific goes out this color of pixel.

In the present embodiment, show 7 kinds of examples that ignition mode is checked that adopt ignition mode A～G at 6 inspection items of i～iv.In addition, as required, can increase and decrease the number of inspection item.And, as ignition mode, cooperate by the detected defective of each inspection item, can use known ignition mode.

(visual check operation)

As the explanation in the above-mentioned background technology part, when carrying out defect inspection to being examined panel P, the defective of some type is difficult to judge by automatic checking device 3.To this, in above-mentioned self-verifying operation, in order to prevent from this type of defective of omission, adopted to set the mode of high inspection sensitivity.Therefore, even, in the self-verifying operation, also be judged as sometimes " NG " as the not problematic defective of product.To this,, be necessary to carry out visual check by the overlooker for the inspection item that is judged out " NG ".That is, carrying out judged result that macroscopic overlooker made is final judged result at each inspection item.

Below, with reference to Fig. 4～Fig. 7 the visual check operation is described.At first, with reference to Fig. 4, macroscopic flow process is described.Fig. 4 is the figure that is used to illustrate macroscopic flow process.In Fig. 4, macroscopic for convenience of explanation flow process, unreferenced self-verifying result, and show the example that shows ignition mode on the panel P being examined.

As mentioned above, in the visual check operation,, show ignition mode on the panel P successively being examined according to the order of display control unit 4 decision.At this, the order that Fig. 4 shows according to ignition mode A to G originally is being examined the example that shows on the panel P.In addition, in Fig. 4, record defective i～iv on ignition mode A～D respectively accordingly, record defective v on ignition mode E and the F accordingly, record defective vi on the ignition mode G accordingly.

That is, in the visual check operation,, also adopt the ignition mode A～G identical to check zero defect i～iv respectively with above-mentioned operation at 6 inspection item i～iv identical with above-mentioned self-verifying operation.And, in the visual check operation, carry out the required time of visual check by utilizing the self-verifying result to save.Therefore, in inspection item of in the self-verifying operation, checking and the inspection item in the visual check operation, checked, at least comprise 1 when using identical ignition mode to check the inspection item of identical defective, just can in the visual check operation, utilize the self-verifying result.Therefore, do not require that all inspection items are all consistent.

At this, for the ease of understanding, for example understand the situation of in visual check operation and self-verifying operation, using identical ignition mode, certainly, also can in visual check operation and self-verifying operation, use different ignition mode.That is, in check system 1, and do not require that the ignition mode of corresponding each inspection item in self-verifying operation and visual check operation is consistent with each other,, can select the ignition mode of being convenient to detect defective for use even identical inspection item is checked operation according to each.

For example, even identical inspection item also has the mutually different situation of optimal ignition mode in visual check operation and self-verifying operation sometimes.Particularly, inspection item is under the situation of line defect, no matter uses which kind of ignition mode in the visual check operation, can both check line defect.Yet, detecting automatically in the operation, owing to be to detect mainly, therefore,, more can photograph the line of light color etc. clearly if adopt gray mode to detect by camera sensor.That is, inspection item is under the situation of line defect, and is different at the optimal ignition mode of visual check operation and self-verifying operation, therefore, preferably adopts different ignition mode in visual check operation and self-verifying operation.

In addition, in check system 1, after the self-verifying operation, carry out the visual check operation, certainly, replaced the visual check operation, also can carry out the self-verifying operation once more.In this case, in the 1st self-verifying operation and the 2nd self-verifying operation, if the spectrum sensitivity difference of filming apparatus then needs to carry out adjustment such as the color that sensitivity is low lightens.That is, preferably in the 1st self-verifying operation and the 2nd self-verifying operation, use different ignition mode.

When in visual check operation and self-verifying operation, using different ignition mode, memory storage (also can utilize data storage device 2) arbitrarily can be set in check system 1, and in advance storage representation in the visual check operation employed ignition mode and in the self-verifying operation data of the corresponding relation between the employed ignition mode.Thus, at each inspection item, can carry out defect inspection in the visual check operation ignition mode different with use in the self-verifying operation.

Then, carry out macroscopic overlooker and confirm one by one that to being presented at the ignition mode that is examined on the panel P checking in each inspection item has zero defect.That is, show that on being examined panel P the overlooker checks zero defect i when lighting Mode A.Then, the overlooker finishes after the inspection of defective i, next ignition mode can be shown to be examined on the panel P.In addition, the display control unit 7 by display control unit 4 decides next ignition mode.

At this, suppose that the input part 8 of display control unit 4 is provided with the switching push button that is used to switch ignition mode, push this switching push button by the overlooker and promptly can show next ignition mode.

As mentioned above, in the visual check operation, push switching key according to the scrutiny program of prior regulation, just can switch successively and be examined the shown ignition mode of panel P according to display control unit 4 indicated orders by the overlooker.Then, the overlooker checks that to shown ignition mode judging in each inspection item has zero defect.

Next, explanation utilizes the self-verifying result to carry out macroscopic method with reference to Fig. 5.Fig. 5 is the figure that is illustrated in an example of the order that is examined the shown ignition mode of panel P in the visual check operation.By in visual check, utilizing the self-verifying result, can save the needed time when carrying out visual check.

Ignition mode more shown in Figure 5 and ignition mode shown in Figure 4 comprise the ignition mode of not putting down in writing among Fig. 5 as can be known in the ignition mode of putting down in writing among Fig. 4.Particularly, in example shown in Figure 5,, and do not show ignition mode C, E, F according to the order demonstration ignition mode of A, B, D, G.

At this, as shown in Figure 3, ignition mode C, E, F and self-verifying result's check result hurdle are that the inspection item of " OK " is corresponding.That is, when utilizing the self-verifying result to carry out visual check, from the DISPLAY ORDER of ignition mode, get rid of the ignition mode that does not detect the inspection item of defective among the self-verifying result.In other words, when utilizing the self-verifying result to carry out visual check, from the DISPLAY ORDER of ignition mode, get rid of the ignition mode that need not to carry out macroscopic inspection item.

By above-mentioned explanation, be examined the last only demonstration of panel P and need carry out macroscopic ignition mode.Particularly, be examined on the panel P, at first show and light Mode A, carry out macroscopic overlooker when pushing switching push button according to the scrutiny program of prior regulation, shown ignition mode will be switched into ignition mode B, when pushing switching push button again, show ignition mode D, when pushing switching push button again, show ignition mode G.

As mentioned above, in check system 1, can save because of showing and confirm the time waste that the ignition mode of flawless inspection item causes, and can avoid the ignition mode that is confirmed as flawless inspection item is carried out the caused futile merit of visual check once more through the self-verifying operation.Thus, finally can shorten the needed time when carrying out visual check.

(DISPLAY ORDER of ignition mode)

As mentioned above, in check system 1, by in the visual check operation to confirming that through the self-verifying operation mode that the ignition mode of flawless inspection item does not show shortens the supervision time.Thereby, though be not particularly limited, adjust by DISPLAY ORDER to ignition mode for the DISPLAY ORDER of the ignition mode on the visual check operation, can further improve macroscopic efficient.In addition, the DISPLAY ORDER of ignition mode can be set by display control unit 4.

That is, preferred, show ignition mode according to the DISPLAY ORDER of prior regulation.If carry out macroscopic overlooker had grasped prior regulation before checking DISPLAY ORDER, just can dope next ignition mode, know and check which kind of defective.Thereby the overlooker can successfully check.

For example, can arrange the DISPLAY ORDER of ignition mode according to the order of inspection item.Promptly, series arrangement ignition mode according to inspection item, and from the ignition mode of arranging, remove and do not need to carry out macroscopic ignition mode, the ignition mode that is removed with remaining ignition mode polishing then, and show ignition mode according to the order behind the polishing.

In example shown in Figure 5, according to the numbering series arrangement from small to large of inspection item i～iv ignition mode, and from arrange, removed and do not needed to carry out macroscopic ignition mode C, E, F, the ignition mode that polishing is removed is also arranged.According to said structure, the overlooker can dope the kind of the defective that next should check to a certain extent, thereby can successfully carry out visual check.

In addition, for example have the inspection item pay particular attention to, be examined panel P at what be judged as " NG " in this inspection item, in the time of need handling in other operation, preferably the ignition mode with this inspection item is presented at first.

Thus, be examined panel P, need not the 2nd inspection item that inspection item is later carried out visual check, promptly can deliver to other operation at what in the inspection item that pays particular attention to, be judged as " NG ".Therefore, unnecessary visual check can be omitted, the needed time when carrying out visual check can be saved.

(demonstration of defective locations and defect pixel color)

As shown in Figure 3, the defective locations that comprises the inspection item that detects defective among the self-verifying result.In the visual check operation, except ignition mode, in the defective locations information that is examined on the panel P defective locations that shows that also expression is checked out by this ignition mode.Thus, be convenient to the overlooker and find defective, can further improve macroscopic efficient.

To this, describe with reference to Fig. 6.Fig. 6 is expression and the ignition mode figure of the demonstration example of display defect positional information together.Show ignition mode being examined on the panel P, and found to be examined the upper left defectiveness d1 of panel P, be examined the part defectiveness d2 that the central authorities of panel P take over.And, also shown the defective locations information 21 of the circle of surrounding defective d1 and the defective locations information 22 of pointing to the arrowhead form of defective d2.

By showing the defective locations information as the expression defective locations of defective locations information 21 and 22, carrying out macroscopic overlooker can the specific simply defective locations that goes out to be examined on the panel P, carries out macroscopic efficient thereby can improve.The expression of defective locations information is not limited to the example among the figure, as long as can express defective position.For example, when representing with the figure that surrounds defective position, figure is not limited to the circle shown in the figure, also can be ellipse or polygon.And, can also represent defective position with the mode of beating bracket.

In addition, according to the kind of defective, defective locations information can be used different figures.Thus, carry out macroscopic overlooker and only see that defective locations information just can be specific goes out the kind of the represented locational defective of this defective locations information, therefore, is easier to detect defective.

In addition, as shown in Figure 3, also include the defect pixel color among the self-verifying result.In the visual check operation, use with the corresponding color of defect pixel color to show above-mentioned defective locations information.Thus, carry out macroscopic overlooker and can be specific simply go out the color of defective pixels, thereby be easier to check out defective.

For example, in the example of Fig. 6, shown ignition mode is ignition mode A, and defective d1 is at position (x ₁, y ₁) on red pixel on the defective checked out, defective d2 is at position (x ₂, y ₂) on green pixel on the defective (with reference to Fig. 3) checked out.In the case, for example, can use red display defective locations information 21, with green display defect positional information 22.Thereby, carry out macroscopic overlooker and can carry out visual check to the pixel that is enclosed in the redness in the defective locations information 21 emphatically, and emphatically the pixel of the pointed locational green of defective locations information 22 is carried out visual check, therefore can check out defective more simply.

In addition, there is no particular limitation for the Show Color of defective locations information, as long as it is specific to help the overlooker that the color of the represented locational defect pixel of this defective locations information is carried out, that is, and do not require the color that use is identical with the defect pixel color.But, identify the color of defect pixel more simply in order to make the overlooker, preferably use the color identical with the defect pixel color.

(flow process that shows control and treatment)

Below, with reference to Fig. 7, the flow process of the demonstration control and treatment of carrying out is described in display control unit 4.Fig. 7 is the process flow diagram that expression shows an example of control and treatment.In the visual check operation, at first, the overlooker sends check result to check result obtaining section 6 and obtains indication by operation inputting part 8, obtains self-verifying result (S1) by check result obtaining section 6 from data storage device 2.Check result obtaining section 6 sends to display control unit 7 with the self-verifying result who obtains.

Next, in display control unit 7, according to the self-verifying result who receives, the ignition mode of using when selecting to carry out visual check (S2).Particularly, display control unit 7 selection self-verifying results' check result hurdle is the ignition mode (with reference to Fig. 3) of the inspection item of " NG ".

Then, display control unit 7 decision is shown to the DISPLAY ORDER of passing through the ignition mode (S3) that S2 selects that is examined on the panel P.As the explanation of being carried out in the DISPLAY ORDER part of above-mentioned ignition mode, can come suitably to set the DISPLAY ORDER of ignition mode as required.At this, (order from small to large of i～vi) shows according to the numeral in the inspection item hurdle that is recorded in the self-verifying result in display control unit 7 decision.

Then, display control unit 7 sends indication (S4) to panel lamp device 5, makes to show by the 1st ignition mode in the order of S3 decision on being examined panel P.In addition, display control unit 7 also to panel lamp device 5 transmit with the corresponding defective locations of inspection item of the 1st ignition mode and defect pixel color (with reference to Fig. 3) (S5).

Panel lamp device 5 is according to the demonstration that receives from display control unit 4 indication, sends and makes this be examined panel P to show that this demonstrations indicates the control signal of lighting of specified ignition mode to being examined panel P.And, panel lamp device 5 is according to the defective locations and the defect pixel color that receive from display control unit 4, make this be examined the control signal of lighting that panel P together shows above-mentioned ignition mode and defective locations information to being examined panel P transmission, wherein, by defective locations information representation defective locations and defect pixel color.

By above-mentioned, be judged as by the self-verifying operation in the middle of the defective inspection item, the defective locations information of the ignition mode of the inspection item that numbering is minimum and its defective locations of expression and defect pixel color together is displayed on and is examined on the panel P.Then, the overlooker checks shown ignition mode, and judges that zero defect is arranged.

Next, the overlooker finishes to be had after the flawless judgement, pushes the switching push button of input part 8.By pushing switching push button, send demonstration from input part 8 to display control unit 7 and switch indication.At this, display control unit 7 wait receptions show switches indication (S6), receives demonstration switching indication back display control unit 7 according to the order that is determined in S3, and (S7) indicated in the demonstration that sends next ignition mode to panel lamp device 5.Then, display control unit 7 transmits the corresponding defective locations of inspection item and the defect pixel color (S8) of the ignition mode of indicating with the demonstration that is sent to lamp device 5.

According to foregoing, next ignition mode together is presented at the defective locations information of representing its defective locations and defect pixel color and is examined on the panel P.Then, the overlooker checks shown ignition mode, and judges that zero defect is arranged.

Then, whether the display control unit 7 that affirmation has transmitted defective locations and defect pixel color to panel lamp device 5 by S8 has sent demonstration indication at all ignition mode of selecting by S2 to panel lamp device 5, that is, confirm whether be examined all ignition mode (S9) that shown on the panel P by the S2 selection.

If exist in the selected ignition mode in S2 not when panel lamp device 5 sends the ignition mode of demonstration indication (S9 is not), display control unit 7 will turn back to waits among the S6 that reception shows the switching indication.On the contrary, if when panel lamp device 5 has sent the demonstration indication of selected all ignition mode in S2 (S9 is for being), display control unit 7 will wait for that receiving check finishes indication.

In addition, check to finish indication and be, macroscopic overlooker forms by operation inputting part 8 inputs by carrying out.That is, the overlooker is to being necessary to carry out macroscopic ignition mode, that is, to all ignition mode of the inspection item that detects defective by the self-verifying operation all finish check after, finish being examined the inspection of panel P by operation inputting part 8.

Failing to confirm to check under the situation that finishes indication (S10 for not), display control unit 7 will turn back to be waited among the S6 receiving and shows and switch indication.And, receiving when showing the switching indication, display control unit 7 sends the demonstration indication of the 1st ignition mode to panel lamp device 5 in S7.That is, whether no matter display control unit 7 sent the ignition mode that shows indication to panel lamp device 5 after the push action that receives switching push button, all can send the demonstration indication of ignition mode successively.

Thus, can demonstrate the 1st ignition mode on the panel P once more being examined.And the overlooker is by pushing switching push button, can make to be examined panel P and to be shown to the ignition mode arbitrarily that had shown so far successively.Thus, for example, can show once more on the panel P that the overlooker thinks the ignition mode that is necessary the inspection item confirmed again being examined.

On the contrary, confirming under the situation of checking the end indication (S10 is for being), display control unit 7 finishes being examined the inspection of panel P.In addition, in check system 1, to a plurality of when being examined panel P and carrying out defect inspection, are examined panel P to 1 and finish and turn back among the S1 after checking, obtain the self-verifying result that the next one is examined panel P, and proceed defect inspection.

(variation that shows control and treatment)

More than the process flow diagram of Shuo Ming Fig. 7 is an example that shows control and treatment, and the demonstration control and treatment of being undertaken by display control unit 4 is not limited to this example.For example, display control unit 4 carries out step S2 at least according to the self-verifying result and gets final product, and promptly selects to have removed the step (S2) that need not to carry out macroscopic ignition mode, and can omit other step.

For example, data storage device 2 is arranged on the inside of display control unit 4, and in data storage device 2, stored self-verifying result's situation in advance, and directly transmit under the situation of check result to display control unit 7 by wired or wireless communication facilities, can omit the step that obtains the self-verifying result of S1.Directly send under self-verifying result's the situation to display control unit 4, can omit data storage device 2 is set.

In addition,, be considered to need not carry out macroscopic ignition mode, therefore can shorten the supervision time owing to having removed by S2 even under the situation of the step (S3) of having omitted the DISPLAY ORDER that determines ignition mode.But, the step of the DISPLAY ORDER by determining ignition mode, the overlooker can more successfully carry out visual check, and is therefore preferred, makes display control unit 7 carry out S3.

According to the kind of defective, be difficult to specific go out defective locations and defective color sometimes.And automatic checking device 3 may not possess defective locations and defective color are carried out specific function sometimes.In this case, can omit the operation of S5, S8.But, preferred under the specific situation that goes out defective locations and defective color of self-verifying operation, by carrying out S5 by display control unit 7 or S8 comes the display defect positional information, make the overlooker can check out defective more simply.

In addition, the flowchart text of Fig. 7 is when display control unit 7 detects demonstration input indication, to send the form that demonstration is indicated at each ignition mode to panel lamp device 5.In addition, can also be with the unified panel lamp device 5 that sends to of the demonstration indication of a plurality of ignition mode.Can omit S6, S7, S9, S10 like this.

In this case, for example can storage part be set on panel lamp device 5, be used to make panel lamp device 5 to switch the input part of ignition mode, and the demonstration indication of the ignition mode that will send over from display control unit 4 is stored in the above-mentioned storage part.Thus, the overlooker sends the switching indication of ignition mode by the above-mentioned input part of operation to panel lamp device 5, thereby can show successively when being examined panel P and carry out macroscopic ignition mode.

(display part make use-case)

As mentioned above, in the visual check operation of check system 1, order according to the rules shows ignition mode.At this, when carrying out visual check, need sometimes the defective of carrying out once confirming is confirmed once more.In this case, want the ignition mode reaffirmed to expend some times sometimes in order to show.

For example, in example shown in Figure 5, carry out after macroscopic overlooker carries out checking for one time to ignition mode A～G,, must show the ignition mode D that is used to check defective iv if when wanting defective iv confirmed again.At this moment, in order to show ignition mode D, need push switching push button, and ignition mode A is switched to ignition mode B, push switching push button once more, ignition mode is switched to ignition mode D.The mode of carrying out this change action can cause macroscopic decrease in efficiency, therefore, should not select for use.

In order to address the above problem a little, on the display part 9 of display control unit 4, shown to make the overlooker more successfully carry out macroscopic supplementary.Below, with reference to Fig. 8 this supplementary is described.Fig. 8 is the figure that represents an example of supplementary shown on the display part 9.

Shown in figure, show 4 ignition mode such as A, B, D, G on the display part 9, also shown detected defective i, ii, iv, vi in each ignition mode simultaneously.That is, show the ignition mode and the defective name of carrying out macroscopic inspection item on the display part 9.

And the ignition mode that is presented on the display part 9 is, carries out macroscopic overlooker and selects by operation inputting part 8, and can be shown to and be examined on the panel.Thus, this overlooker only need select desirable ignition mode from the ignition mode on being presented at display part 9, just this ignition mode can be shown to be examined on the panel.That is, and compare, can more easily carry out the affirmation again of defective according to said structure by ignition mode is switched the situation that shows desirable ignition mode successively.

In addition, it is also conceivable that following situation, that is, when carrying out visual check, demonstrate the ignition mode that in the self-verifying operation, is judged as flawless inspection item.At this situation, can be in the kind that shows the entry name after the self-verifying operation, be judged as flawless inspection item and ignition mode, defective on the display part 9 etc.Thus, carry out macroscopic overlooker and can be simply from full ignition mode, select desirable ignition mode, and it is presented at is examined on the panel P.

In addition, preferred, to distinguishing demonstration through being judged as flawless inspection item after the self-verifying operation and being judged as defective inspection item.As distinguishing the method that shows, for example can enumerate color separation, change display position, add the whole bag of tricks such as literal and mark.

In addition, as the method that display part 9 shown ignition mode are selected, can use known method.For example, input part 8 possesses under the situation as the indicating equipment of mouse etc., when having carried out clicking the operation of the regulations such as ignition mode that pointer aims at, promptly can judge and select above-mentioned ignition mode.In addition, can also judge selecteed ignition mode by receiving the operation that load button carried out to input part 8.And display part 9 can be a touch-screen.Display part 9 is under the situation of touch-screen, can be judged as the ignition mode of having selected to be presented on the display part 9 on the position contacting of detecting.Thus, the overlooker is by touching desirable ignition mode, just can be from the shown ignition mode of display part 9 this ignition mode of selection.Display part 9 is under the situation of touch-screen, and display part 9 has both the function of input part 8.

And, in example shown in Figure 8, show the form that on display part 9, shows ignition mode and defective name.At this, on display part 9, demonstrate at least can specific ignition mode information (for example, ignition mode name and inspection item) get final product.

(variation 1)

In the above-described embodiment, illustrated that display control unit 4 decides the example of the DISPLAY ORDER of the ignition mode when carrying out visual check according to obtained self-verifying result in the self-verifying operation.But the present invention is not limited thereto example.

For example, repeatedly carrying out under the situation of self-verifying, display control unit 4 can also decide when next carrying out self-verifying the DISPLAY ORDER of the ignition mode that will use according to the self-verifying result.Thus, in self-verifying, being judged as flawless inspection item, can in the self-verifying of next carrying out, omitting inspection, thereby can save the supervision time this.

Similarly, repeatedly carrying out under the macroscopic situation, display control unit 4 can also decide when next carrying out visual check the structure of the DISPLAY ORDER of the ignition mode that will use according to the visual check result.Thus, in visual check, being judged as flawless inspection item, can being omitted in the ensuing visual check this is checked, thereby can save the supervision time.

In addition, in the above-described embodiment, only illustrated the inspection item of having found defective in self-verifying has been carried out macroscopic example.In addition, for the part of the inspection item of in self-verifying, having found defective, also can carry out visual check.For example, the inspection item for being difficult to detect by automatic checking device regardless of its self-verifying result, all can carry out visual check.Thereby, can prevent problem because of the detection failure omission defective of automatic checking device.

And, in the above-described embodiment, the example that is not presented at the ignition mode of the inspection item of not finding defective in the self-verifying when carrying out visual check has been described, but the present invention is not limited to this example.For example, by the ignition mode of the inspection item of not finding defective in self-verifying and the ignition mode of having found the inspection item of defective are distinguished demonstration, also the supervision time can be shortened.

For example, when on being examined panel P, showing the ignition mode of the inspection item fail to detect defective, can show that together expression does not detect the defects detection information of defective with this ignition mode.By foregoing, carry out macroscopic overlooker's a glance and just can find out the situation of failing to detect defective in the ignition mode shown on being examined panel P, therefore, can push switching push button rapidly, ignition mode is switched to next ignition mode.

In addition, there is no particular limitation to above-mentioned defects detection information, identify that to be examined the shown ignition mode of panel P be the ignition mode that does not detect defective in self-verifying so long as can help to carry out macroscopic overlooker, the ignition mode that has still detected defective gets final product.For example, can be with literal and mark etc. as defects detection information.

In addition,, can use expression to detect the information of defective and the information that expression does not detect defective, also can use one of them as defects detection information.This be because, carry out macroscopic overlooker and can judge, showing the ignition mode that expression detected the defects detection information of defective promptly is the ignition mode that has detected defective; And not showing the ignition mode that expression detected the defects detection information of defective promptly is the ignition mode that does not detect defective.Thereby,, can use above-mentioned defective locations to detect information as defects detection information.

In addition, when display control unit 7 shows above-mentioned ignition mode successively in the visual check operation, if shown ignition mode is to be used for carrying out the ignition mode that display defect detects to be judged as flawless inspection item in the self-verifying operation, then, shown ignition mode can be switched to next ignition mode from beginning demonstration through after the official hour.

According to said structure, because not detecting the ignition mode of the inspection item of defective can automatically switch by self-verifying, therefore, carrying out macroscopic overlooker does not need need not to carry out macroscopicly, and the ignition mode that does not detect the inspection item of defective by self-verifying is carried out blocked operation.

In addition, when setting the time of afore mentioned rules, the ignition mode of avoiding not detecting display defect is continued to show and is exceeded the phenomenon of the time that needs show that the time that setting can be carried out the 2nd inspection operation smoothly gets final product.For example, the time set of afore mentioned rules can be become below the several seconds.Thus, need not to carry out macroscopic ignition mode can be switched rapidly, thereby, when can shorten the supervision time, can also prevent and also carry out macroscopic phenomenon need not to carry out macroscopic ignition mode.

Method as the ignition mode that automaticallyes switch after at the appointed time for example has, and the method that timer etc. is used for the device of instrumentation time is set on display control unit 4.Particularly, display control unit 7 is after panel lamp device 5 sends the demonstration indication of ignition mode, and the result confirms to self-verifying.If under this ignition mode, do not detect defective, just start above-mentioned timer, after beginning instrumentation, timer during through official hour, sends the demonstration indication of next ignition mode.

(variation 2)

As illustrating of Fig. 6 etc., by with ignition mode display defect positional information together, carry out macroscopic overlooker and can be specific simply go out defective locations, thereby can shorten the supervision time.Next, with reference to Fig. 9, explanation can not only make that the overlooker is specific simply to go out defective locations, can also carry out the variation that defective is judged more simply.

Fig. 9 is the figure that expression and ignition mode have together shown the demonstration example of enlarged image.At this, suppose to be examined on the panel P and show ignition mode, and detect by the self-verifying operation and to be examined the coordinate (X of panel P ₁, Y ₁) the position on have defective.As shown in the figure, show enlarged image 32 on the panel P being examined, this enlarged image 32 is to amplify to have represented including coordinate (X ₁, Y ₁) on the image in zone 31 of defective.

By showing enlarged image 32, carry out macroscopic overlooker and can identify the fine defective that is examined on the panel P simply.Thereby, compare the visual check that can carry out expeditiously according to the method for described demonstration enlarged image by the method for using amplification such as magnifier may exist the position of defective to carry out the defective judgement with of the prior art.This method is in the operation that is particularly useful for microscopic defects such as point defect are detected.

Next, about describing in the enlarged image display process that is examined demonstration enlarged image 32 on the panel P.That is, at first, display control unit 7 is obtained the defective locations of each inspection item with reference to the self-verifying result who obtains from data storage device 2.

Then, for each defective locations, generate the enlarged image in the zone of the specialized range that comprises this defective locations by display control unit 7.Particularly, display control unit 7 reads in the image that is examined panel P that photographs in the self-verifying operation from data storage device 2, and the zone of the specialized range of the image that read is amplified.At this, as long as the scope of amplifying comprises the scope of defective locations, this is not particularly limited, for example, get final product amplifying away from the scope of n (n for positive number) arbitrarily from defective locations.

(embodiment 2)

In the above-described embodiment, illustrated by from display object, removing the ignition mode that in the self-verifying operation, is judged as flawless inspection item and shortened the check system 1 of supervision time.Next,, the ignition mode that is shown by further minimizing is described in the visual check operation, thereby can further shortens the embodiment of the check system of supervision time with reference to Figure 10 to Figure 13.

The check system of present embodiment has the structure identical with check system shown in Figure 11.Identical in the action of self-verifying operation in addition, and the above-mentioned embodiment.The difference of the check system 1 of above-mentioned embodiment and the check system of present embodiment is to show control and treatment, below is explained.In addition, to being same as the identical reference symbol of structure tag in the above-mentioned embodiment, and omit explanation.

Figure 10 is an illustration process flow diagram of the demonstration control and treatment of the check system that relates to of expression present embodiment.Identical with above-mentioned embodiment, also carry out the demonstration control and treatment in the present embodiment by display control unit 7.At first, display control unit 7 is obtained the self-verifying result from data storage device 2, and selects to carry out macroscopic ignition mode (S21).Particularly, display control unit 7 selection self-verifying results' check result hurdle is the ignition mode (with reference to Fig. 3) of the inspection item of " NG ".

Next, display control unit 7 is obtained the defective locations (S22) of detected each inspection item in the self-verifying operation from the above-mentioned self-verifying result who obtains.Then, display control unit 7 is set background area (S23) on each defective locations of obtaining.The display control unit 7 of present embodiment shows the ignition mode that is used to detect display defect on each background area, thus, can reduce the number of times that switches ignition mode, thereby can shorten the supervision time.

Below, the establishing method of background area is described according to Figure 11.Figure 11 is an illustration figure of expression background area establishing method.Figure 11 expresses, and the partial pixel that is examined panel P that has shown ignition mode has been carried out the state that amplifies.As shown in the figure, be examined and show bad candidate 41 on the panel P.That is,, judge defectiveness on the position of bad candidate 41 by the self-verifying operation in this hypothesis.

Be examined on the panel P, the zone that comprises this bad candidate 41 promptly becomes background area 42.That is,, as shown in figure 11, cut apart, obtain the cut zone of a plurality of matrix shape being examined panel P in this hypothesis, and the cut zone that will comprise bad candidate 41 zone 42 as a setting.

As long as background area 42 comprises the zone of bad candidate 41, be not limited to illustrated embodiment.For example, in cut zone, except the zone that comprises bad candidate 41, comprise that being adjacent to this regional cut zone also can be used as background area 42.In this case, compare with illustrated embodiment, therefore background area 42 wider, when showing ignition mode on background area 42, be easier to discern bad candidate 41.

In addition, for example in the self-verifying operation, can calculate the region area of each bad candidate 41 and with this as self-verifying result output, and set the region area that background area 42 has bad candidate 41 and amplify the area that specified multiple obtained.In addition, also can be with the zone that comprises from the scope of the outer rim predetermined distance of bad candidate 41, zone 42 as a setting.

Set after the background area by said method, display control unit 7 is judged each background area of setting whether overlapping (S24).Particularly, when display control unit 7 shows each background area of setting by S23 on being examined panel P, judge whether to have at least part background area overlaid.

If judge background area when not overlapping (S24 for not), display control unit 7 will generate and synthesize ignition mode, and this synthetic ignition mode is meant, be the ignition mode that unit detects the bad candidate that this background area comprised with each background area.Then, display control unit 7 sends to panel lamp device 5 and shows indication, makes in the synthetic ignition mode (S25) that is examined the above-mentioned generation of demonstration on the panel P, and finishes to show control and treatment.

On the contrary, if when judging the background area lap being arranged (S24 is a "Yes"), display control unit 7 is selected overlapping background areas (S26).When having the equitant part in a plurality of background areas, many places, display control unit 7 is from selecting 1 background area everywhere.At this, when display control unit 7 is selected the background area, select to make the zone of the number minimizing of synthesizing ignition mode to be advisable.

Next, display control unit 7 generates the synthetic ignition mode that includes selected background area, and shows indication by sending to panel lamp device 5, is being examined the synthetic ignition mode (S27) that shows above-mentioned generation on the panel P.That is, when display control unit 7 demonstrates ignition mode on being examined panel P, not on the display area of lap, demonstrate the ignition mode that is used for detecting the defective that is included in this background area in the background area.Then, on 1 background area of background area overlaid part, demonstrate the ignition mode that is used for detecting the defective that is included in this background area.

Then, display control unit 7 includes generation the synthetic ignition mode (S28) that is not presented at the background area that is examined on the panel P as yet in the background area of setting by S23.Particularly, non-selected background area promptly is not to be presented at the background area that is examined on the panel P as yet in S26.Therefore, display control unit 7 shows the ignition mode that is used to detect the defective that this background area comprises on this background area.In addition, in not being presented at the background area that is examined on the panel P, if at least a portion that should zone zone is the same with S26 during with other background area overlaid, display control unit 7 is selected 1 background area from equitant background area, and generates synthetic ignition mode.

Then, display control unit 7 is waited for the demonstration switching indication on the input part 8,, waits for the action (S29) of pushing switching push button that is.Display control unit 7 confirms after the demonstration switching indication that input part 8 is carried out, and sends to panel lamp device 5 to show indication (S30), and is being examined the synthetic ignition mode that demonstration generates by S28 on the panel P.

Next, whether display control unit 7 is confirmed to exist in the background area of setting by S23 and be not examined the background area (S31) that demonstrates the ignition mode that is used to detect the defective that this background area comprises on the panel P as yet.If when having the background area that does not show above-mentioned ignition mode as yet (S31 is a "Yes"), display control unit 7 returns S28, is created on not the synthetic ignition mode that demonstrates the ignition mode that is used to detect the defective that this background area comprises on the background area that shows.On the contrary, when if there is no not showing the background area of above-mentioned ignition mode as yet (S31 is a "No"), display control unit 7 finishes to show control and treatment.

As mentioned above, in the demonstration control and treatment of present embodiment, show synthetic ignition mode, wherein the synthetic ignition mode here is, when carrying out visual check, in the pattern that has shown the ignition mode that is used to detect the defective on above-mentioned each defective locations on detected each defective locations by the self-verifying operation.By above-mentioned formation, can reduce the number of times that switches ignition mode, and can further shorten required time when carrying out visual check.In addition, be examined under the situation that detects a plurality of defective candidates that are close on the panel P by the self-verifying operation, the background area can overlap sometimes.Therefore, according to the demonstration control and treatment of present embodiment, under the overlapped situation in background area, only show ignition mode on 1 background area in overlapping background area.Thus, even under the equitant situation in background area, carry out macroscopic overlooker and also can identify the defective candidate simply.
