Claim:
1. A method of driving a display device, the method comprising: connecting a plurality of data lines, formed in a panel, to ground during a touch preparation period after a touch sensing period arrives until a plurality of sensing pulses are supplied to a plurality of driving electrodes, the plurality of sensing pulses including at least a first set of sensing pulses to be applied to a first driving electrode of the plurality of driving electrodes during a first portion of the touch sensing period, and a second set of sensing pulses to be supplied to a second driving electrode of the plurality of driving electrodes during a second portion of the touch sensing period; floating the plurality of data lines while the first set of sensing pulses are supplied to the first of driving electrode after the touch preparation period; connecting the plurality of data lines to ground while no sensing pulse is supplied to the plurality of driving electrodes, after the first set of sensing pulses have been supplied to the first driving electrode, but before the second set of sensing pulses are supplied to the second driving electrode; and floating the plurality of data lines while the second set of sensing pulses are supplied to the second of driving electrode.
