Abstract: Disclosed are an in-cell touch type touch display device that includes a touch display panel, where a plurality of touch sensors are disposed, and a driving circuit unit. Each of the plurality of touch sensors are disposed to correspond to a plurality of subpixels, and each of the plurality of touch sensors may include one or more touch switches. The one or more touch switches disposed in each of the plurality of touch sensors divisionally drive the plurality of touch sensors by 1/n (where n is a natural number equal to or more than two).

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.

Abstract: A display device and a method for driving the same are disclosed. The display device includes a display panel including pixels and touch sensors, the display panel being time-division driven in a display driving period and a touch sensor driving period, a main power integrated circuit (IC) configured to produce a first gate high voltage and a second gate high voltage less than the first gate high voltage, a touch power IC configured to produce a first AC signal having an amplitude corresponding to the second gate high voltage, and a gate driver configured to produce a gate pulse based on the first gate high voltage to supply the gate pulse to gate lines connected to the pixels during the display driving period and supply the first AC signal to the gate lines during the touch sensor driving period.

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.
