Detailed Description
In order to make the technical problems, technical solutions and advantages to be solved by the embodiments of the present invention clearer, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1 and 2, in the touch substrate of the related art, the conductive trace 2 is disposed at the periphery of the effective touch area 1, and the conductive trace 2 is connected to the ground point for conducting away static electricity on the touch substrate, but because the conductive trace 2 is disposed only at the periphery of the effective touch area 1, this design method can only prevent ESD at the periphery of the effective touch area 1 from attacking the touch substrate, and cannot ensure the ESD resistance inside the touch substrate, which results in a poor ESD resistance of the touch substrate.
In order to solve the above problems, embodiments of the present invention provide a touch substrate, a manufacturing method thereof, and a touch electronic device, which can improve ESD resistance of the touch substrate.
The embodiment of the invention provides a touch substrate, which comprises a touch electrode, wherein the touch electrode is arranged in an effective touch area, as shown in fig. 3, the touch substrate further comprises a conductive layer 21, the conductive layer 21 is arranged in the effective touch area 1 and is grounded, and the conductive layer 21 is insulated from the touch electrode.

Optionally, the conductive layer 21 and the touch electrode are located on a substrate of the touch substrate, and in order to ensure that static electricity transmitted from the outside to the touch substrate is conducted away in time, the conductive layer 21 is preferably disposed on a side of the touch electrode away from the substrate, so that when the static electricity is transmitted to the touch substrate, the external static electricity first contacts the conductive layer 21, and static electricity can be conducted away in time.
At first, the capacitive touch screen mainly adopts ITO to manufacture the touch electrode, but because the In element of ITO is a rare metal, the material is only less and less, and the price is more and more expensive. Under the circumstances, people slowly begin to search for new materials to replace the ITO material, but the performance of the touch screen of Metal Mesh is not affected by the ITO material, and the touch screen of Metal Mesh is produced by using common Metal materials, such as Metal aluminum, copper, silver and the like, to manufacture the touch electrode. When the touch electrode is applied to a display device, the display of the display device is required not to be affected, so the touch electrode is designed to be in a metal grid shape, and in order to ensure the optical performance of the touch substrate, the conductive layer also adopts a metal grid with the same shape as the touch electrode.

When static electricity enters the touch substrate, the metal grids in the effective touch area can effectively resist ESD and rapidly remove the ESD, so that the ESD resistance of the touch substrate is improved.
In the above embodiment, the conductive layer connected to the ground point is located in the effective touch area, and the touch electrode and the conductive layer adopt the Metal grids with the same shape, so that the ESD resistance of the Metal Mesh touch screen can be effectively increased, and the optical performance of the touch screen can be effectively improved.

The touch substrate is simple in design, convenient and easy to implement, the touch electrode and the conducting layer are made of metal, the material price is low, the expensive material ITO is not needed, and the production cost of the touch substrate is reduced.
The embodiment of the present invention further provides a manufacturing method of a touch substrate, including forming a touch electrode in an effective touch area, where the manufacturing method further includes:
and forming a grounded conductive layer in the effective touch area, wherein the conductive layer is insulated from the touch electrode.
