Abstract:
A display device and method are discussed. The display device can include a display panel having a pixel array with touch sensors embedded therein; a display driving circuit that time-divides 1 frame period into a plurality of pixel driving periods and a plurality of touch sensing periods and writes input image data to the pixels block by block during the pixel driving periods; and a touch sensing circuit that drives the touch sensors during the touch sensing periods. The display driving circuit includes a gate driver formed on the display panel. A shift register of the gate driver includes a transistor that supplies a high-potential voltage to a Q node of the shift register in response to a compensation pulse generated during the touch sensing periods.
