Abstract:
A touch sensor integrated type display device includes: a display panel including first and second panel blocks (PBs), each including a pixel array with embedded touch sensors, a display driving circuit providing image data to pixels of the first and second PBs during a display period, and a touch sensing circuit driving the touch sensors of the first and second PBs during a touch sensing period, the display driving circuit including a shift register sequentially providing gate pulses (GPs) to gate lines, the shift register including: a first stage group (SG) applying a GP to gate lines in the first PB, a bridge stage connected in cascade to a last stage of the first SG, and providing a first carry signal, and a second SG applying a GP to gate lines in the second PB, a first stage of the second SG operating in response to the first carry signal.
