Abstract
A disclosed touch sensor integrated display device includes a display panel; and a data drive circuit configured to set a gate-source voltage to turn on a driving TFT in the display panel by applying a data voltage for touch sensing to a gate node of the driving TFT through a data line and a reference voltage to a source node of the driving TFT through a sensing line, during a reset period based on a scan control signal and a sensing control signal, and to output a sensing value by sensing a change in a source-drain current of the driving TFT caused by touch input, during a sensing period subsequent to the reset period.
