Abstract:
A touch sensor integrated type display device includes: a display panel including: pixels connected to data lines and gate lines and division-driven into a plurality of panel blocks, and a plurality of touch sensors connected to the pixels, a display driving circuit providing data of an input image to the pixels in multiple display periods divided from one frame period, and a touch sensing circuit driving the touch sensors and sensing a touch input in a touch sensing period allocated between the display periods of the frame period, adjacent panel blocks being division-driven in the display periods that are separated from each other with the touch sensing period, in which the touch sensors are driven, interposed therebetween, the display driving circuit including a shift register: shifting a gate pulse in accordance with a shift clock timing, and sequentially supplying the gate pulse to the gate lines.
