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 (10), in which a pixel array is virtually divided into a plurality of touch blocks (BL1, BL2, BL3, BL4), each touch block includes pixels (P) displaying an input image and at least one sensing target dummy pixel (TPXL) sensing a touch input, and the sensing target dummy pixel (TPXL) includes a driving TFT controlling a source-drain current based on a gate-source voltage, and a panel drive circuit, which in a touch sensing period (TSEN), supplies a scan control signal and a sensing control signal to the sensing target dummy pixel (TPXL) and sets the gate-source voltage suitable to turn on the driving TFT by applying a touch driving data voltage to a gate node (Ng) of the driving TFT and applying a reference voltage to a source node (Ns) of the driving TFT.
