Embodiment 1
[0032] Such as Figures 2a to 2b As shown, change the cutting shape of the edge of the polarizer in contact with the silver paste, and change the shape and outline of the lower edge of the polarizer from a vertically cut straight line to a vertically cut folded line, as shown in Figure 2a with 2b shown. Depend on Figure 2b It can be seen that the present invention increases the contact area between the silver paste and the cross-section pressure-sensitive adhesive of the polarizer, and improves the electrostatic discharge capacity. Compared with the prior art, greater silver paste coating deviation (position deviation, glue width deviation) can be allowed. Specifically, for the conventional method, the coating tolerance for better contact of the edge polarizer edge on the silver paste coating is very limited; for the present invention, from Figure 2b It can be seen that the coating tolerance can be effectively increased.
Embodiment 2
[0034] Such as Figures 3a to 3c As shown, changing the cutting shape of the edge of the polarizer in contact with the silver paste, and changing the shape of the lower edge of the polarizer from a vertically cut straight line to a vertically cut square wave, trapezoidal, and wavy shape can also achieve increased The contact area between the silver paste and the pressure-sensitive adhesive on the cross-section of the polarizer can improve the effect of electrostatic discharge ability; at the same time, it can also allow greater silver paste coating deviation (position deviation, glue width deviation).
Embodiment 3
[0036] Such as Figures 3a to 3b As shown, change the cutting method of the edge of the polarizer in contact with the silver paste, and change the shape and outline of the lower edge of the polarizer from a vertically cut straight line to a non-perpendicular cut (inclined at a certain angle, 0-90°) straight line, Figure 3a The shape profile of the lower edge of the polarizer shown is a straight line cut vertically, Figure 3b The shape profile of the lower edge of the polarizer shown is a straight line cut non-perpendicularly (inclined at a certain angle, 0-90°), which can also increase the contact area between the silver paste and the pressure-sensitive adhesive on the cross-section of the polarizer, and improve the electrostatic discharge. The effect of ability, at the same time, can also allow greater silver paste coating deviation (position deviation, glue width deviation).
[0037] Preferably, improvements are made on the basis of the above scheme to obtain a preferred...
