It is detailed introduce this programme before, the technology train of thought of this programme is simply introduced:
It is bonded between display module and part to be fit by glue, increases the opposite fastness of the two.
In the prior art, it is bonded using solid gum using hollow, is exactly the surrounding gluing along display module, will show
Mould group and part to be fit bond.But aforesaid way, since bond area is small, fastness is poor, and the light transmittance of solid gum
Difference influences display effect.
Inventor is bonded through overtesting, using optical cement using hollow, and the light transmittance of optical cement is relatively high, but firm
Solidity is not significantly improved.
In turn, optical cement is coated in entire display area by inventor, and fastness is ensured, but due to optics
The mobility of glue is larger, and excessive glue phenomenon is also very serious.
In order to solve the problems, such as excessive glue, inventor devises following technical solution:
The present embodiment provides a kind of display devices, and as depicted in figs. 1 and 2, Fig. 1 is display provided by the embodiment of the present invention
A kind of structural schematic diagram of device, Fig. 2 are a kind of sectional view in Fig. 1 provided by the embodiment of the present invention at the position AA ', this is aobvious
Showing device 100 includes:
Display module 11, is stacked the part to be fit 13 in 11 light emission side of display module, and part 13 to be fit includes visual
Region 131 and frame region 133 around visible area 131.It is understood that display device 100 can be in the present embodiment
Light emitting structure is pushed up, also can be bottom light emitting structure, the present embodiment is not particularly limited it, illustratively, with shown in fig. 1
The relativeness between all parts is introduced for the light emitting structure of top.
With continued reference to Fig. 1, the optical cement 15 between display module 11 and part to be fit 13 is set, and optical cement 15 is used for will
Display module 11 is bonded with part 13 to be fit, optical cement 15 part 13 to be fit orthographic projection in the plane cover visible area
131.It is understood that area of the area of optical cement 15 not less than visible area 131 in part 13 to be fit, optical cement 15
Area is relatively large, conducive to the fastness between part 13 to be fit and display module 11, avoids gluing caused by the missing of optical cement
It is not firm to close.
Wherein, with continued reference to Fig. 1 and Fig. 2, it is provided with the first receipts glue groove region 1331 in frame region 133, as shown in figure 1 two
Region between a dotted line, inevitable, optical cement covers visible area 131, and the first receipts glue groove region 1331 may be provided at frame
Close to the side of visible area 131, in this way can be filled into extra excessive glue in the region first receives glue groove 135 in region 133
It is interior, play the role of preventing excessive glue.
Specifically, first receives the position of glue groove 135 as shown in Fig. 2, first receives glue groove region 1331 close to optical cement 15
One side surface is provided with the first receipts glue groove 135, and the edge of optical cement 15 first receive glue groove region 1331 in the plane
Orthographic projection is located at first and receives in glue groove region 1331.It is understood that on the direction far from visible area 131, optical cement
15 outer edge is received in glue groove region 1331 first, such design, and in coating procedure, extra optical cement 15 can be by the
One receipts glue groove is stored, and is not overflowed, is avoided and impact to display device, and ensure that part 13 to be fit and display mould
Fastness between group 11.
Optical cement in the present embodiment can be liquid optical cement (LOCA), when liquid, coated in the visual of part 13 to be fit
In region 131, part 13 to be fit and display module 11 can firmly be fit together after its solidification.In perfect condition
Under, the edge of optical cement is flushed with the edge of visible area, on the one hand can guarantee the jail of display module Yu part to be fit in this way
Solidity, the case where on the other hand avoiding optical cement excessive glue or starved.In fact, during coating optical cement, due to light
The more liquid of glue is learned, in the case where guaranteeing not starved, there will be the case where excessive glue.
It should be noted that how the case where being directed to excessive glue, be arranged the first receipts glue groove, inventor have passed through repeatedly to be tried repeatedly
It tests, is below simply summarized the technology train of thought that glue groove is received in setting first:
One is be arranged in a side surface of the display module close to part to be fit, display module is right after completing encapsulation
Display module opens up the first receipts glue groove close to a side surface of part to be fit, finds after inventor's repetition test:If guaranteeing aobvious
The intensity for showing mould group makes it have certain endurance, then integrated close to the surface of the side of part to be fit due to display module
Spend higher, settable first, which receives the area of glue groove and first, receives the settable depth of glue groove limited, the case where still having excessive glue
Occur;If the quantity and depth of the first receipts glue groove are arranged according to the glue overflow amount estimated, the intensity drop of display module will lead to
It is low, the service life of display module is reduced, even display module can be directly scrapped when serious, cause economic loss.
Another kind is the side surface that display module is arranged in close to part to be fit, to aobvious before display module encapsulation
Show that mould group receives glue groove close to a side surface of part to be fit setting first, is found after inventor's repetition test:It will affect in this way
Subsequent packaging effect will also result in economic loss so that encapsulation rate declines.
Another kind is, as described in above embodiment, is arranged in part to be fit close to a side surface of display module
First receives glue groove, at this point, since part to be fit is thicker, and its component and circuit for being not carried out the functions such as touch-control above, because
This settable areal extent is wider, and the limitation according to the depth and quantity of glue overflow amount setting the first receipts glue groove is smaller, more important
Be that can't treat the intensity of fitting part after the first receipts glue groove is arranged to impact.
To sum up, it is set by the frame region 133 in part 13 to be fit close to a side surface of optical cement 15 in the present embodiment
The first receipts glue groove 135 is set, on the one hand in coating procedure, so that extra optical cement is stored by the first receipts glue groove 135, is avoided
Optical cement overflows display module 11 and impacts to display device, on the other hand since optical cement is coated in entire visible area
In 131, it is ensured that the fastness between display module 11 and part to be fit 13, thickness of yet another aspect due to part 13 to be fit
Thicker, the area of settable first receipts glue groove 135 is wider, and after glue groove 135 is received in setting first, can't be to be fit
The intensity of part 13 impacts.Above embodiment can obviously improve excessive glue situation in the prior art.
The relationship between total glue overflow amount of optical cement and the volume of the first receipts glue groove is briefly described below:
Total glue overflow amount V of optical cement and first receives the volume V of glue groove1Between relationship it is as follows:
V≤P*V1,
Wherein, total glue overflow amount V=(W1*L1-W0*L0) * H,
V indicates total glue overflow amount of optical cement, and P indicates the first quantity for receiving glue groove, V1Indicate the first volume for receiving glue groove;W1
Width after indicating optical cement excessive glue, L1Length after indicating optical cement excessive glue, W0Indicate the design width of optical cement, L0It indicates
The design length of optical cement, H indicate the thickness of optical cement, 0.1mm≤H≤0.15mm.
Detailed explanation is carried out to above-mentioned formula below:
W1*L1* H indicates the amount of the optical cement of precoating, for the definite value of precognition;The design width W of optical cement0Can be regarded as to
The width of the visible area of fitting part, the design length L of optical cement0It can be regarded as the length of the visible area of part to be fit, W0*
L0That is to say, the area of visible area is also the definite value of a precognition.
And the thickness H of optical cement has relationship with pressing dynamics when being bonded, pressing dynamics are big, and the thickness of optical cement is small, always
Glue overflow amount V is more, otherwise pressing dynamics are small, and the thickness of optical cement is big, and total glue overflow amount V is small.According to technological level, when by pressing dynamics
After a certain range, the thickness H of corresponding optical cement is determined in certain fluctuation range for control, illustratively can be
Between 0.1mm≤H≤0.15mm.At this point, after the range of the thickness H of optical cement determines, it can be according to the maximum value of optical cement H
Calculate total glue overflow amount VmaxAs long as all first volumes for receiving glue groove for guaranteeing that first receives in glue groove region are greater than VmaxIt can guarantee
The case where display device is not in excessive glue.
Therefore, the first quantity P* first for receiving glue groove receives the volume V of glue groove1Then indicate the amount for the optical cement that can be stored.
Total glue overflow amount be less than or equal to above-mentioned value after, then can surface the present embodiment extra glue can all be stored, keep away
The case where exempting from excessive glue appearance.
Also, when one timing of equipment, one timing of pressing dynamics can adjust the thickness H's of optical cement by theoretical calculation
Range avoids the range that the thickness H of optical cement is obtained by way of multiple technique, Jin Erti to adapt to technological level
Working efficiency has been risen, cost is saved.
It should be noted that each variable being related in the present embodiment includes fabrication error, the technique of each variable
Error can be depending on specific technique, and the present embodiment is not particularly limited it.
In one embodiment, as shown in figure 3, it is another at the position AA ' in Fig. 1 provided by the embodiment of the present invention
A kind of sectional view, first receive 1331 inward flange of glue groove region display module 11 orthographic projection in the plane and visible area
131 edge display module 11 distance between orthographic projection in the plane be L1,0≤L1≤0.1mm, and first receives glue
The outer edge in slot region 1331 display module between outer edge of the orthographic projection with display module in the plane at a distance from be
L2,0≤L2≤0.1mm.
As shown in figure 3, on visible area 131 to the direction of frame region 133 (direction as see arrows 17 in fig 3), first
Receive glue groove region 1331 inward flange it is understood that close to visible area 131 edge;First receives the outside in glue groove region 1331
Edge can be regarded as the edge far from visible area 131.That is, in the present embodiment, on the direction far from visible area 131,
First receive glue groove region 1331 maximum width, be display module 11 Edge Distance visible area 131 edge between away from
From.
The first width for receiving glue groove region 1331 can be arranged according to specific product and glue-spread in the present embodiment, will be more
Remaining optical cement is accommodated in the first receipts glue groove 135, avoids the spilling of glue, and since the thickness of part 13 to be fit is thicker,
The area of settable first receipts glue groove 135 is wider, after glue groove 135 is received in setting first, can't treat the strong of fitting part 13
Degree impacts.It also avoids going out the case where the first receipts glue groove 135 of setting in display module 11 impacts its intensity
It is existing.
Further, as shown in Figure 1, the first receipts glue groove 135 is evenly distributed in the first receipts glue groove region 1331, and first
The shape for receiving glue groove 135 is identical.
The first receipts glue groove 135 in the present embodiment is evenly distributed in the first receipts glue groove region 1331, and it is extra to may make
Optical cement 15 uniformly stored by the first receipts glue groove 135, excessive glue phenomenon caused by avoiding storage uneven.
It should be noted that the shape that Fig. 1 illustratively shows the top view of the first receipts glue groove 135 is rectangle, still
The shape of the first receipts glue groove 135 is not particularly limited in this implementation.
Several first specific structures for receiving glue groove 135 are illustratively shown below:
The first, as shown in figure 4, a kind of its structural schematic diagram for the first receipts glue groove provided by the embodiment of the present invention,
The first shape for receiving glue groove 135 can be cylindrical body in the present embodiment, and the basal diameter of cylindrical body is d, wherein 30 μm≤d≤60 μ
m。
Second, as shown in Figure 5 and Figure 6, Fig. 5 is that another structure of display device provided by the embodiment of the present invention is shown
It is intended to, since first receives glue groove 135 as half-via, part 13 to be fit is set close to the side of display module 11, therefore
The first receipts glue groove 135 is not can be appreciated that in positive top view, Fig. 5 receives glue groove region for its clear relative position, by first
1331 are set as 65% transparency.Fig. 6 is the first another structural schematic diagram for receiving glue groove provided by the embodiment of the present invention,
In the present embodiment, first receive glue groove 135 can be rotary table, and close to display module 11 a side opening in display module 11 just
Projection covers orthographic projection of the side opening far from display module 11 in display module 11.Also, in visible area 131 to side
On the direction of frame region 133, the width close to a side opening of display module 11 is b, 30 μm≤b≤60 μm, separate to show mould
The width of one side opening of group 11 is c, 30 μm≤c≤60 μm, inevitable, close to the width b of the opening of 11 side of display module
Greater than the opening width c far from 11 side of display module, frustum cone structure could be formed in this way, and close to the side of optical cement
The case where width of the opening of (close to display module side) is larger, is conducive to storage optical cement, avoids excessive glue appearance.
Also, in display module 11 to the direction of part 13 to be fit, first receive glue groove 135 depth be a, 30 μm≤a
≤60μm。
You need to add is that since the first receipts glue groove 135 is half-via, the first depth a for receiving glue groove 135 cannot
Enough it is greater than the thickness of part 13 to be fit, and takes into account the fastness of part 13 to be fit, the first depth a setting for receiving glue groove 135 exists
Between 30 μm≤a≤60 μm.
