Specific embodiment
Band entity pointer shows need to obtain through hole to install pointer in display panel internal drilling, and run through in the region that drills
Hole periphery should be located at through hole to prevent liquid crystal leakage and boring procedure stress array base palte and color membrane substrates rupture and separating
The necessary solid complete and reliable sealing of the sealing ring of outer peripheral areas, especially vehicle-mounted product bore diameter needs 10mm even more big,
Therefore through hole peripheral seal ring is reliable complete close after the solidification diameter of bore area fluid sealant need to meet bore diameter and drill
Envelope.
In the LCDs that exploitation shows with entity pointer, encapsulated liquid crystals need to do close to the present inventor after the drilling of bore area
Sealing, the open area that bore area silk-screen leaks fluid sealant is designed according to bezel seal glue extension multiple.But result of the test：Bore area
The extension solidification diameter solidification diameter that extends theoretical much smaller than design-calculated after sealing glue solidifying, test of many times analysis should be silk
Print scraper scraped drilling region because open region is greatly so that part fluid sealant is blown off, caused the regional seal glue extension multiple to be less than
Bezel seal glue extension multiple.
The present inventor collects drilling region fluid sealant extension multiple and designs bigger open area according to pre-stage test.But examination
Test result：Extension solidification diameter after the sealing glue solidifying of bore area meets boring requirement, but all occurs in that fluid sealant by gas
Breaking through causes the brilliant defect of increasing back sealing ring leakage that drills, and has the expansion of bubble hot pressing heated gas to cause in analysis fluid sealant close
Sealing is broken through, and test of many times cannot all solve the defect.
The defect that solid fluid sealant is broken through by gas cannot be solved, the present inventor is set in bore area using sealing ring opening
Meter, is open for hot pressing scavenging action, sealing-in after extending by sealing ring.But result of the test：Part display screen sealing ring is opened
Mouthful place's sealing is complete, at outs open cannot sealing-in, but partly seal and complete still all occur what fluid sealant was broken through by gas
Defect；And sealing complete display screen array base palte and color membrane substrates in boring procedure have also appeared vast scale cracking defect,
And solid fluid sealant has gas to break through the defect without substrate breakage after the defect of fluid sealant but drilling before, analysis reason mainly should
Should because fluid sealant be provided without it is solid, between color membrane substrates and array base palte into crack cavity, stress causes in boring procedure
Glass ruptures, it was demonstrated that design sealing ring is infeasible, can only use fluid sealant solid design.
The present inventor still uses solid design bore area fluid sealant, same half tone to design various opening diameters, carry out many
Secondary experiment is to find the reason for fluid sealant breaks through defect by gas and solution.By many experiments and repeated authentication, this
Inventor has found：Gas breaks through defect slightly when opening diameter design is small, when the more big then gas punching of opening diameter design
The more serious linear relationship of broken defect.
As shown in figure 1, bore area fluid sealant 3 ' needs spread diameter big to meet bore diameter demand, need silk-screen large area close
Sealing, i.e., big opening diameter.And after working as the equal equal glue of glue knife of silk-screen printing process, open region edge seal glue 3 ' is against half tone opening edge
Edge wall is adhered to, and because fluid sealant is absorbed by edge of opening wall influence opening area centers regional seal glue 3 ' toward edge of opening wall, is caused
The globulate concave surface of open region fluid sealant 3 ', fluid sealant 3 ' is transferred to the face of array base palte 1 ' globulate after silk-screen glue scraper is uniformly scraped
There is gas in concave surface 31 ' during concave surface 31 ', array base palte 1 ' and the laminating of color membrane substrates 2 ', heated gas in hot pressing
Fluid sealant 3 ' is broken through in expansion, causes fluid sealant 3 ' completely cannot reliably seal, and the sealing ring 4 ' after drilling is not solid complete
Cannot reliably seal, easily exist stress in liquid crystal leakage, boring procedure cause array base palte 1 ' and the rupture of color membrane substrates 2 ' and
The defect of separation, as shown in Figure 2.
In order to overcome above-mentioned deficiency, the utility model provides a kind of silk-screen half tone 7, and it is used for a silk-screen and is drilled

≤95μm。
For bore area, the volume after silk-screen after the leak adhesive volume and sealing glue solidifying of fluid sealant is equal, i.e., bore area is close
Sealing volume V2=π(d1/2)2*h1=π(d0/2)2*h02, d0It is the open region diameter or leak adhesive area diameter of silk-screen half tone, h02It is position
Screen thickness at the opening of bore area, h1For heat-pressure curing fluid sealant prolongs after array base palte and the relative laminating of color membrane substrates
Height after exhibition（This is highly determined by the support silicon ball being blended in fluid sealant）, d1For the solidification diameter after sealing glue solidifying its
