Abstract: A display device is provided that includes a display panel divided into a plurality of blocks, each of the blocks including a plurality of lines of pixels and configured to be driven in a time-division manner with a touch sensing period interposed between two display periods, the two display periods corresponding to display periods for two adjacent blocks of the plurality of blocks. The display device further includes a display driving circuit, and a touch sensing unit configured to receive a sync signal for synchronizing the display driving circuit with the touch sensing unit. The display device is configured to change the sync signal every predetermined period of time so as to shift the touch sensing period interposed between the two display periods.
