TOUCH PANEL FOR ELECTROSTATIC DISCHARGE PROTECTION AND ELECTRONIC DEVICE USING THE SAME

摘要

A touch panel and an electronic device are provided. The touch panel includes a sensing electrode array, a touch controller, and an electrostatic discharge (ESD) protection circuit. The sensing electrode array is arranged in two dimensional array of n rows and m columns for generating a sensing signal in response to a touch on the touch panel. The touch controller is operationally connected to the sensing electrode array for receiving the sensing signal and identifying the touch on the touch screen. The ESD protection circuit includes ESD protection units each being electrically connected to a corresponding row or column of the sensing electrode array and the touch controller for electrostatic discharge protection.
