Claim:
1. A display device comprising: a display panel including data lines and gate lines; a touch screen including a plurality of touch sensors; a data driving circuit for supplying a data voltage to the data lines; a gate driving circuit for supplying a gate voltage to the gate lines; a touch sensing circuit for applying a touch driving signal to the touch sensors to sense a touch on the touch screen; and a timing controller for controlling timings of operation of the display device, the display device being operated in a plurality of frame periods, each of the frame periods including at least a first driving period for driving the touch sensors and a second driving period for performing display on the display panel, wherein the data voltage to be applied to one or more of the data lines in the second driving period is applied in advance to the one or more of the data lines in a duration adjacent to a boundary between the first driving period and the second driving period with the gate lines being inactivated, to precharge the one or more of the data lines prior to the gate lines being activated by the gate voltage.
