Background

The touch screen often generates friction with other objects in the use process, and a contact static phenomenon can be generated in the friction process. The ambient environment also creates static electricity in some way, which is transferred to the touch screen surface by air discharge, causing air discharge to the touch screen surface. When charges generated by contact discharge and air discharge are accumulated to a certain degree, certain influence is generated on a conducting layer in the touch screen, and when the antistatic capacity of the conducting layer cannot bear the contacted charges, the conducting layer can be broken or even broken, so that the touch screen has poor functions and the user experience is influenced;

the edge wiring structure of the traditional touch screen is designed as shown in fig. 3, a GND7 line in an edge wiring area is a smooth massive metal wiring, when voltage formed by contact discharge or voltage formed by air discharge reaches the surface of a capacitance layer through the touch screen, the voltage contacted by the capacitance layer in the touch screen is actually lower than the voltage on the surface of the touch screen, charges on the surface of the capacitance layer can be irregularly and continuously dispersed in all directions of a conductive layer, when the conductive layer 6 cannot bear continuous impact of the charges, the charges can break down the conductive layer to cause disconnection of the conductive layer 6, cause poor functions and greatly reduce the production yield of the touch screen;

generally speaking, the touch screen can bear +/-8 KV of contact discharge and +/-15 KV of air discharge, and when the voltage formed by the contact discharge exceeds +/-8 KV or the voltage formed by the air discharge exceeds +/-15 KV, the conductive layer of the touch screen is easily damaged by electrostatic shock, resulting in functional failure.

SUMMERY OF THE UTILITY MODEL

For solving the above-mentioned problem that exists among the prior art, the utility model provides an improve touch-sensitive screen of antistatic properties has and prevents that contact discharge and air discharge from causing the electrostatic shock to the touch-sensitive screen in the use, improves the characteristics of touch-sensitive screen antistatic properties.
