Abstract

A touch sensor integrated display device and a method for driving the same are disclosed. The touch sensor integrated display device includes a display panel, in which a pixel array is divided into a plurality of touch blocks, each touch block includes pixels displaying an input image and a sensing target dummy pixel sensing a touch input, and the sensing target dummy pixel includes a dummy driving TFT configured to control a source-drain current based on a gate-source voltage, and a panel drive circuit, which in a touch sensing period, supplies a scan control signal and a sensing control signal to the sensing target dummy pixel and sets the gate-source voltage to turn on the dummy driving TFT by applying a touch driving data voltage to a gate node of the dummy driving TFT and applying a reference voltage to a source node of the dummy driving TFT.
