Embodiment Construction
[0034] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0035] The invention provides a display module and a bonding method thereof, such as Figure 1-2 As shown, the display module includes: a liquid crystal glass 10 , an upper polarizer 20 , a lower polarizer 30 , an OCA adhesive layer 40 and a cover plate 50 . Wherein, the liquid crystal glass 10 is provided with a blind hole 11, and the edge of the blind hole 11 is provided with a circle of light-shielding area 12, and the light-shielding area 12 plays the role of light-shielding to prevent the liquid crystal glass 10 from passing through the blind hole 11. light leak. The upper and lower polarizers 20 and 30 are respectively arranged above and below the liquid crystal glass 10, corresponding to the position of the blind hole 11, and the upper and lower polarizers are respectively provided with a first through hole 21, a second The through h...

The invention discloses a display module and a laminating method thereof, and the display module comprises liquid crystal glass which is provided with a blind hole, and the edge of the blind hole is provided with a circle of shading area; an upper polaroid and a lower polaroid which are respectively arranged above and below the liquid crystal glass, the upper polaroid and the lower polaroid are respectively provided with a first through hole and a second through hole corresponding to the blind holes, and the vertical projections of the hole edges of the first through hole and the second through hole fall onto the shading area; a OCA glue layer which is arranged above the upper polaroid, and the OCA glue layer is provided with a third through hole corresponding to the blind hole; a cover plate which is arranged above the OCA layer, an annular silk-screen printing ink area corresponding to the blind hole is arranged on the cover plate, and vertical projections of the inner edge and the outer edge of the silk-screen printing ink area fall onto the shading area; and the vertical projection of the hole edge of the third through hole falls onto the silk-screen printing ink area. According to the display module and the laminating method thereof, the problems that in the prior art, after the OCA glue is fully laminated with the liquid crystal glass and the cover plate, the blind hole area is prone to bubbles and difficult to defoam are effectively solved, and the yield is greatly increased.
Description
technical field [0001] The invention relates to the technical field of bonding production of display modules, in particular to a display module and a bonding method thereof. Background technique [0002] OCA (Optically Clear Adhesive) is an optically transparent layer of special substrate-free double-sided adhesive, which is a special adhesive for bonding transparent optical components (such as lenses, etc.). It is required to be colorless and transparent, with light transmittance above 90%, good bonding strength, curable at room temperature or medium temperature, and small curing shrinkage. It is widely used in the bonding process of the cover plate of the display module and the liquid crystal glass. In the bonding process of display modules, the OCA full bonding process is generally used, that is, the OCA glue covers the entire cover plate and the liquid crystal glass for bonding, and then defoaming is performed after bonding, but bubbles are still prone to appear in the ...
