    Abstract: A display device includes a display panel including a display driving circuit, and a touch sensing circuit. The display panel includes first and second panel blocks, each including pixel arrays including touch sensors. The display driving circuit includes a shift register for sequentially outputting a gate pulse applied to a gate line. The shift register includes first and second shift registers and a compensation stage. The first shift register applies a gate pulse to gate lines arranged in the first panel block, and the second shift register applies a gate pulse to gate lines arranged in the second panel block during at least a portion of the display period when a node of the second shift register is charged to a predetermined level. The compensation stage charges the node of the second shift register upon receiving a bridge clock during a touch sensing period of the first panel block.
