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 each pixel (P) of a pixel array includes an OLED and a driving TFT applying a source-drain current to the OLED, the pixel array is virtually divided into touch blocks (BL1, ..., BLk), and at least one sensing target pixel line (HL1, ..., HL3m) is assigned to each touch block (BL1, ..., BLk), and a panel drive circuit (12, 13) which, in a touch sensing period (TSEN), supplies a scan control signal and a sensing control signal to pixels (P) disposed on the sensing target pixel line (HL1, ..., HL3m), sets a gate-source voltage of the driving TFT suitable to turn on the driving TFT, and outputs a sensing value by sensing a change in the source-drain current of the driving TFT caused by a touch input.
