AI Technical Summary

Technical Problem

Existing touchscreens lack sufficient anti-static capability when exposed to electrostatic voltages exceeding 15KV, failing to effectively protect the touch chip and potentially causing damage.

Method used

A resistor array and an anti-static board are set on a flexible circuit board, and a moisture-proof board is added to its surface and a heat-conducting board is added to its back to improve the anti-static capability to 17KV. At the same time, a moisture-proof board is set on the surface of the anti-static board to prevent moisture from getting in, and a heat-conducting board is added to facilitate heat dissipation.

Benefits of technology

It enables the touchscreen to operate normally under electrostatic voltages up to 17KV, preventing electrostatic damage and moisture, and ensuring fast response and clear display.
