DISPLAY DEVICE AND DRIVING METHOD THEREOF

摘要

Disclosed is a display device. The display device includes a panel into which a touch panel including a plurality of driving electrodes and a plurality of receiving electrodes is built, a touch sensing unit configured to supply a plurality of sensing pulses to the plurality of driving electrodes during a touch sensing period, a driver configured to drive the panel to allow the panel to display an image during an image display period, and a data line controller configured to connect a plurality of data lines to ground in a sensing pulse non-output period where the plurality of the sensing pulses are not supplied to the plurality of driving electrodes during the touch sensing period.

主权项

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; and floating the plurality of data lines while the plurality of sensing pulses are supplied to the plurality of driving electrodes until the touch sensing period is ended after the touch preparation period.
