Problems solved by technology

However, in actual use, there are still more product damages caused by static electricity
The main reason may be that the static electricity in the touch display device is not completely discharged only through the peripheral metal wiring, and some of the static electricity will enter the touch display device, resulting in bridge point damage or breakdown of functional areas. occur

Abstract

The embodiment of the invention provides a touch substrate, a preparation method thereof and a touch display device, relates to the technical field of touch, and can improve the antistatic capability of the touch display device. The touch substrate comprises an underlying substrate, wherein the underlying substrate is divided into a touch area and a shading area which surrounds the touch area; a first ground wire is arranged in the shading area of the underlying substrate and comprises a first terminal exposed out of the surface of the touch substrate; a second ground wire which is positioned in different layers with the first ground wire is also arranged in the shading area; and the second ground wire comprises a second terminal exposed out of the surface of the touch substrate, wherein the first terminal and the second terminal are not overlapped along a direction vertical to the underlying substrate. The touch substrate is used for improving the antistatic capability.

Description

technical field [0001] The present invention relates to the field of touch technology, in particular to a touch substrate, a preparation method thereof, and a touch display device. Background technique [0002] During the actual use of touch display devices, the wiring, bridge points and even functional areas of the touch display device are often broken down due to the accumulation of static electricity, which eventually leads to damage to the touch function of the touch display device, which directly and seriously Affect the use of the actual function of the product. [0003] In the prior art, in order to avoid electrostatic damage, metal wires are usually arranged around the touch display device, and the static electricity of the touch display device is exported through the peripheral metal wires and connected to the ground. However, in actual use, there are still many damages to products caused by static electricity. The main reason may be that the static electricity in...
