Abstract
Discussed is a display device with integrated touch screen and a method of driving the same. The display device includes a panel including a plurality of driving electrodes and a plurality of sensing electrodes, a touch IC, and a display driver IC. The touch IC generates a first driving pulse, and determines whether there is a touch using a plurality of sensing signals generated by the sensing electrodes. When the panel operates a touch driving mode, the display driver IC generates a second driving pulse with the first driving pulse to apply the second driving pulse to the driving electrodes and receives the sensing signals from the respective sensing electrodes to transfer the sensing signals to the touch IC.
