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.
