Abstract
An embodiment relates to a pixel sensing technique. By supplying a precharge voltage to a sensing line using an amplifier used in pixel sensing, it is possible to minimize differences between precharge voltages of sensing lines and solve a crosstalk problem between the sensing lines, while not increasing a size of a pixel sensing device.
