Claim Text:
1. A display device with an integrated touch screen, comprising: a panel having a plurality of driving electrodes and sensing electrodes; a display driver IC configured to apply a driving pulse to the plurality of driving electrodes and receive a plurality of sensing signals from the sensing electrodes when the panel operates in a touch driving mode, and configured to apply a common voltage to the plurality of driving electrodes and sensing electrodes when the panel operates in a display driving mode; and a touch IC configured to generate the driving pulse and apply the driving pulse to the display driver IC, receive the sensing signals from the display driver IC, and determine whether there is a touch, wherein the touch IC includes a sensing unit configured to sense whether there is a touch by use of a touch sensing reference voltage applied to the sensing unit and having the same level as a minimum voltage of the driving pulse.
