Abstract:
A display device integrated with a touch screen panel, and a method of driving the same, can prevent parasitic capacitance that would otherwise increase the load during a touch operation, lower the accuracy of touch sensing, or make touch sensing impossible. The display device includes data lines, gate lines, and a plurality of electrodes spaced apart from each other. A common voltage is applied to the electrodes in a display driving mode and a touch drive signal is applied to one or more of the electrodes in a touch driving mode. A data voltage is applied to the data lines in the display driving mode. A scan signal is supplied sequentially to the gate lines in the display driving mode and the touch drive signal or a signal corresponding to the touch drive signal is applied to one or more of the gate lines in the touch driving mode.
