Abstract:
A display device includes a panel comprising a plurality of driving electrodes and a plurality of receiving electrodes; a panel driver sequentially supplying a scan pulse to a plurality of gate lines corresponding to a first driving electrode of the plurality of driving electrodes, and after a touch sensing period, sequentially supplying a scan pulse to a plurality of gate lines corresponding to a second driving electrode of the plurality of driving electrodes, wherein the panel driver repeatedly performs the sequentially supplying of the scan pulse; and a touch sensing unit sequentially supplying a driving voltage to at least two or more of the plurality of driving electrodes to determine whether there is a touch during the touch sensing period.
