Problems solved by technology

[0004] Existing touch screens include a touch area for touch detection and a wiring area surrounding the touch area. In the wiring area, conductive wiring is made on a black matrix pattern. The black matrix pattern is generally made of carbon balls. Generally, the insulation performance of the black matrix pattern is better, but after multiple high-temperature processes, the resistivity of the black matrix pattern decreases, and the insulation performance decreases. In this way, if the distance between two adjacent conductive traces is relatively close in the trace area, Static electricity will be discharged through the black matrix pattern between these two conductive traces, resulting in ESD between the two conductive traces
