DETAILED DESCRIPTION

[0023] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the relevant drawings. The drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly and comprehensively understood.

[0024] In order to prevent the AMOLED glass from being damaged by static electricity, especially the TP touch function area, a structure to improve the anti-static effect of the AMOLED touch function area is designed. The specific solution is as follows:

[0025] like Figure 1-2 As shown, a structure for improving the anti-static property of an AMOLED touch functional area includes: a polarizer 200, an upper glass 500, and a TP FPC 400. The polarizer 200 is bound to a TP binding area 100 on the surface of the upper glass 500, and a first GND block 510 for conducting static electricity is provided in the binding area 100 on the surface of the upper glass. A silver paste dot 300 is used as a conductive connector to conduct static electricity between the polarizer 200 and the upper glass 500, and the second GND block on the TP FPC 400 is connected to the first GND block 510 on the surface of the upper glass to release static electricity.

[0026] like Figure 2As shown, the polarizer 200 includes: a protective film 201, an anti-scratch triacetyl cellulose film 202, a polyvinyl alcohol film 203, a triacetyl cellulose film 204, a first pressure-sensitive adhesive layer 205, a 1 / 4 compensation film 206, a second pressure-sensitive adhesive layer 207, and a peeling film 208, which are stacked in sequence from top to bottom. In this embodiment, an antistatic layer 210 containing an electrostatic agent is provided on the second pressure-sensitive adhesive layer 207, so that when static electricity enters the module, it can be conducted out through the upper polarizer 200.

[0027] The surface resistance of the antistatic layer 210 reaches 10 10 -10 11 Ohm, can provide good anti-static ability and prevent TP ITO traces from being interrupted.

[0028] like Figure 1 and 3 As shown, the TP TIO function of AMOLED is to increase the first GND block 510 on the upper glass 500 and the surface of the binding area of ​​the upper glass 500, and then connect the antistatic layer 210 of the polarizer 200 with the first GND block 510 through the silver paste dot 300, and the first GND block 510 and the second GND block 410 on the TP FPC 400 are also connected and conducted, and at the same time, the second GND block 410 is connected and conducted with the client shell by using conductive cloth. With such a structure, the static electricity of the module can be quickly conducted to the client shell and released quickly.

[0029] like Figure 1 , 2 As shown in 3, static electricity will quickly pass through the upper polarizer 200 → silver paste dot 300 → upper glass leak first GND block 510 → second GND block 410 → conductive cloth → casing, so that no matter where the static electricity is injected, it can be quickly released to the casing, thereby protecting the TP functional area and improving the anti-static ability of AMOLED.

[0030] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
