Embodiment 1

[0041] figure 1 A plan view of a display screen with an antistatic structure provided for an embodiment of the present application.

[0042] Such as figure 1As shown, this embodiment provides a display screen 100 with an antistatic structure, which includes a display area 101 and a non-display area 102 . Wherein, the display area 101 has a plurality of pixel units 401 arranged in an array, and each pixel unit 401 includes red sub-pixels, green sub-pixels and blue sub-pixels.

[0043] The display screen 100 includes a first metal wire 10 , a second metal wire 20 and a protection device 30 .

[0044] A plurality of first metal wires 10 are disposed in the display area 101 , and at least one end of each first metal wire 10 extends to the non-display area 102 .

[0045] A plurality of the second metal wires 20 are disposed in the display area 101 , and at least one end of each second metal wire 20 extends to the non-display area 102 .

[0046] A plurality of the protection dev...

Embodiment 2

[0073] This embodiment provides a display screen with an antistatic structure, including all the technical features of Embodiment 1, and at least one metal layer and an insulating layer.

[0074] Figure 10 A cross-sectional view of a display screen with an antistatic structure provided for an embodiment of the present application.

[0075] Such as Figure 10 As shown, the display screen 100 located in the non-display area 102 includes a substrate 201 , a first metal layer 202 , a first insulating layer 203 , a second metal layer 204 , a second insulating layer 205 and a third metal layer 206 .

[0076] Specifically, the second insulating layer 205 is disposed on the top surface of the second metal layer 204 . The third metal layer 206 is disposed on the top surface of the second insulating layer 205 , and the third metal layer 206 is etched to form a third metal wire. The second insulating layer 205 includes a third through hole 304 penetrating to the top surface of the se...

Abstract

The invention discloses a display screen with an anti-static structure and a preparation method of display screen, the display screen comprises a display area and a non-display area, a plurality of first metal wires are arranged in the display area, and at least one end of each first metal wire extends to the non-display area; the plurality of second metal wires are arranged in the display area, and at least one end of each second metal wire extends to the non-display area; and a plurality of protection devices are located in the non-display area, and each protection device is connected to one end of the first metal wire or one end of the second metal wire. According to the display screen, the electrostatic protection effect can be achieved on the wiring of the display area without a discharge path or a TFT discharge type circuit, the width of the non-display area of the display screen is saved, the protection effect is good, the technological process is simple, and the display area process in the display screen can be compatible.

Description

technical field [0001] The present application relates to the field of antistatic, in particular to a display screen with an antistatic structure and a preparation method thereof. Background technique [0002] The whole machine assembled from the display screen in the effective display area will directly punch holes when testing the electrostatic capacity, and the effective display area of ​​the display screen is a hole area for placing components. If there is no electrostatic protection design , static electricity will directly damage the components placed here. Moreover, the routing of the effective display area of ​​the display screen will also be affected by static electricity, resulting in poor display and affecting the display quality of the mobile phone. In the process of manufacturing display screens, static electricity will cause many adverse events, so the design of anti-static breakdown (ESD, electrostatic discharge) structures on LCD, OLED and mini / micro display...
