Abstract:
1. A display device with an integrated touch screen, comprising: a panel including electrodes divided into n number of groups, wherein n is an integer more than or equal to two; a display driver IC configured to: apply a common voltage of a first level to the n divided groups, when a driving mode of the panel is a display driving mode, and sequentially select at least one of the n divided groups and apply a touch scan signal to the at least one selected group, while applying the common voltage of the first level to unselected n divided groups, when the driving mode of the panel is a touch driving mode; and a touch IC configured to generate the touch scan signal to apply the touch scan signal to the display driver IC, wherein the display driver IC includes a switching unit configured to apply the touch scan signal from the touch IC to the at least one selected group, while applying the common voltage of the first level to the unselected n divided groups, during the touch driving mode.
