Abstract: A display device includes a display panel including an active area, in which pixels for displaying an input image and touch sensors for sensing a touch input are located, and a bezel area outside the active area and a power integrated circuit (IC) configured to produce DC (direct current) power and AC (alternating current) power and supply the DC power and the AC power to power lines disposed in the bezel area. The power lines include a first power line, to which the DC power is supplied, and a second power line, to which the AC power is supplied. The bezel area includes a first bezel area, in which the first power line is located, and a second bezel area, in which the second power line is located.

Abstract: Disclosed is an in-cell touch type touch display device and a method of driving the same, which prevent an error of a touch operation from being caused by the delay of a touch report occurring in a large-screen touch display device. The touch display device includes a touch panel, including a plurality of touch sensors, and a driving circuit unit. The driving circuit unit may include a plurality of source/touch driving ICs and a touch IC. The plurality of source/touch driving ICs may supply a touch driving signal to the plurality of touch sensors. The touch IC may perform a touch operation based on touch reports received from the plurality of source/touch driving ICs.
