Abstract:
1. A touch panel, comprising: a touch screen, for sensing a touch position; and a display arranged below the touch screen; wherein the touch screen comprises a patterned, transparent first conductive layer comprising a first sensing pattern and a shielding pattern, in which the touch screen employs the sensing pattern as a sensing layer for sensing the touch position, and the display employs the shielding pattern as an electrostatic protection layer to protect the display from external electric discharge; and wherein the display comprises: wherein the display comprises a frame period comprising a pixel period for driving the liquid crystal layer and a sensing period for sensing the touch position, a shielding voltage supplied to the shielding pattern and a common voltage supplied to the counter electrode during the pixel period, and a sensing voltage supplied to the first sensing pattern during the sensing period.
