Abstract:
1. A display device with an integrated touch screen, comprising: a panel having a plurality of driving electrodes and sensing electrodes; and a touch IC configured to apply a driving pulse to the plurality of driving electrodes and receive a plurality of sensing signals from the sensing electrodes to determine whether there is a touch 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; 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, wherein the common voltage has the same level as the touch sensing reference voltage and the minimum voltage of the driving pulse, and wherein the common voltage is different from a ground voltage.
