Display screen cover plate, display assembly, and method for manufacturing the display assembly

Abstract

A cover plate of a display screen, a display assembly and a method for manufacturing the same are provided by the invention. The cover plate of a display screen comprise a substrate, the substrate hasa visible region and a shielding region arranged at the outer periphery of the visible region. The display screen cover plate further comprises a shielding bottom layer arranged at the shielding region and a shielding layer arranged at a side of the shielding bottom layer opposite to the substrate. The shielding layer is provided with an exhaust groove, and an exhaust passage is formed inside theexhaust groove. The exhaust groove has an oppositely disposed inner side edge and an outer side edge, the inner side edge including a first inner side edge and a second inner side edge, the first inner side edge and the second inner side edge are located on both sides of the visible region, and the outer side edge penetrates the shielding layer. In the bonding process of the display screen coverplate, the air between the display screen cover plate and the display layer can be discharged through an exhaust groove, thereby effectively reducing bonding bubbles and improving bonding quality andproduct yield.

Description

technical field [0001] The invention relates to the technical field of display screen production, in particular to a display screen cover plate, a display component and a preparation method of the display component. Background technique [0002] In recent years, more and more touch display devices adopt full-bonded screens, that is, OCA optical glue or UV glue is used to realize the seamless bonding of the display cover and the display layer. However, due to the height difference between the ink layer printed on the display cover and the visible area, air bubbles are likely to remain on the edge of the ink layer during the bonding process. Part of the air bubbles can be removed through defoaming treatment, but the thickness of the ink layer and the on-site bonding process are relatively high, and there is a possibility of reoccurrence, so the air bubble problem cannot be effectively solved. [0003] A capacitive touch screen is now disclosed in the industry, which has a gla...

AI Technical Summary

Problems solved by technology

However, due to the height difference between the ink layer printed on the display cover and the visible area, air bubbles are likely to remain on the edge of the ink layer during the lamination process.

Part of the bubbles can be removed by defoaming treatment, but the thickness of the ink layer and the on-site bonding process are high, and there is a possibility of recurrence, which cannot effectively solve the problem of bubbles

[0003] A capacitive touch screen is now disclosed in the industry, which has a glass layer and an ink layer. The ink layer at least includes a first ink layer and a second ink layer printed on the glass in sequence. Indent away from the window area of ​​the touch screen, that is, set the edge of the ink layer in a stepped shape to reduce the possible bubbles at the edge of the ink layer. However, in the above-mentioned solution, the step difference between the edge of the ink layer and the substrate has not been eliminated, and it is difficult to completely eliminate the bonding air bubbles

In addition, in the process of pressing and laminating the display cover in a predetermined direction by the existing laminating machine, it is difficult to eliminate the air bubbles at the edge of the ink layer on the end side of the laminating direction.
