AI Technical Summary

Technical Problem

The display module or circuit board of the touch display device has weak anti-static discharge (ESD) capabilities, which leads to problems such as display or touch function in practical applications, and may even lead to damage to the device.

Method used

A circuit board module is designed, including a touch chip, a first circuit board, a second circuit board and at least one conductive connection portion. By electrically connecting the touch chip to the first circuit board, and electrically connecting the grounding parts of the first and second circuit boards through the conductive connection, a grounding network is formed, thereby improving the anti-static ability of the touch chip.

Benefits of technology

Through this circuit board module, the anti-static ability of the touch display device is significantly improved, reducing the risk of touch chip damage during ESD test, thereby avoiding the problem of touch failure.
