Abstract
Disclosed is a display device with an integrated touch screen. The display device includes a panel including 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 during a display driving mode. The display driver IC is configured to apply a driving pulse to the plurality of driving electrodes during the touch driving mode of the panel and receive one or more sensing signals from the plurality of sensing electrodes responsive to a touch of the integrated touch screen during the touch driving mode. The display driver IC is configured to adjust a magnitude of the driving pulse from a first level to a second level and subsequently from the second level to a third level during the touch driving mode of the panel.
