Zusammenfassung: | 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, each pixel of a pixel array including an OLED and a driving TFT applying a source-drain current to the OLED, the pixel array being divided into touch blocks, each touch block including pixels and a sensing target pixel line coupled to a subset of the pixels, and a panel drive circuit configured to, in a touch sensing period, supply a scan control signal and a sensing control signal to the sensing target pixel line corresponding to a touch block, set a gate-source voltage of the driving TFT coupled to the sensing target pixel line to turn on the driving TFT, and output a sensing value by sensing a change in the source-drain current of the driving TFT caused by a touch input. |
