Abstract
A touch sensor-integrated display device includes a display panel with a pixel array divided into a plurality of touch blocks, each touch block having a plurality of pixels for displaying an input image and at least one touch pixel for sensing touch input; a data drive circuit that applies a charging voltage to the touch pixel in each touch block through a touch sensing line and then senses an electrical charge discharged from the touch pixel and outputs the sensing result as a touch sensing value, wherein a signal line commonly connected to the pixels and the touch pixel in each touch block is used as the touch sensing line; and a timing controller that detects touch input based on the touch sensing value.
