Claim:
1. A touch and gesture sensing system comprising: a display panel comprising a pixel array, sensors, and sensor lines connected to the sensors; a display driving circuit that writes a data voltage to the pixels of the pixel array during a display driving period; and a sensor driving circuit that applies a touch sensor driving signal to the sensors to sense touch input during a touch sensing period and applies a gesture sensor driving signal to the sensors to sense gesture input during a gesture sensing period, wherein the display driving period is divided into a plurality of pixel driving periods, the touch sensing period is divided into a plurality of touch sensing periods, and a number of pixel driving periods is greater than a number of touch sensing periods; and wherein an equal number of pixel driving periods and touch sensing periods are arranged in an alternating manner, the gesture sensing period is divided into a plurality of gesture sensing periods, and a remaining number of pixel driving periods and the gesture sensing periods of the plurality of gesture sensing periods are arranged in an alternating manner.
