摘要：
A touch panel includes a touch sensor, a liquid crystal panel, and a reverse circuit. The reverse circuit receives common voltage ripples of the liquid crystal panel, and outputs reversed common voltage ripples after reversing the common voltage ripples. After the touch sensor receives the reversed common voltage ripples, the touch sensor outputs a sensing signal according to the reversed common voltage ripples.
