The disclosure provides a method of driving a touch panel which includes a plurality of touch sensing electrodes and a plurality of display pixels. Each of the display pixels includes a light emission element and a driving transistor. Each of the touch sensing electrodes is coupled to the light emission element of at least one of the plurality of display pixels and served as an electrode of the light emission element. The method includes transmitting a first driving signal to at least one of the touch sensing electrodes during a touch sensing period, wherein the touch sensing electrode is coupled to a first power receiving terminal of the corresponding display pixel; transmitting a first power supply voltage to the first power receiving terminal during a display period; and controlling the light emission element of the corresponding display pixel to keep turned on when the first driving signal is transmitted.
