Abstract
A display device with integrated touch screen is provided. The display device may include a panel, a display driver IC, and a touch IC. The panel may include a plurality of driving electrodes and sensing electrodes. The display driver IC may apply a driving pulse to the driving electrodes and receive a plurality of sensing signals from the sensing electrodes when the panel operates in a touch driving mode, and, when the panel operates in a display driving mode, the display driver IC may apply a common voltage to the driving electrodes and sensing electrodes. The touch IC may generate the driving pulse and apply the driving pulse to the display driver IC, and may receive the sensing signals from the display driver IC to determine whether there is a touch. The touch IC may include a sensing unit sensing whether there is a touch.
