Claim Text:
1. A display device with integrated touch screen, the display device comprising: a panel configured to include a plurality of driving electrodes and a plurality of sensing electrodes; and a display driver IC configured to apply a common voltage to the plurality of driving electrodes and the plurality of sensing electrodes when the panel operates in a display driving mode, and when the panel operates in a touch driving mode, generate a pulse-modulated driving pulse according to a timing pulse and a pulse modulation control signal to apply the pulse-modulated driving pulse to the plurality of driving electrodes, and respectively receive a plurality of sensing signals from the plurality of sensing electrodes, wherein the driving pulse comprises an up section voltage which is pulse-modulated based on an up pulse modulation voltage, a high level driving voltage, a down section voltage which is pulse-modulated based on a down pulse modulation voltage, and a low level driving voltage.
