Claim:
1. A display device with integrated touch screen, the display device comprising: a panel configured to include a plurality of electrodes that are divided into n number of groups (where n is an integer equal to or more than two); a display driver circuit configured to, apply a common voltage to the plurality of electrodes during a display driving mode of a first frame, apply a touch scan signal to a first group of the n groups and a first adjacent electrode unit included in a second group adjacent to the first group during a touch driving mode of the first frame, wherein the first adjacent electrode unit includes an outermost electrode string of the second group adjacent to the first group, the outermost electrode string of the second group including at least a first outermost electrode and a second outermost electrode of the second group that are configured such that the touch scan signal is applied to the first outermost electrode via a first signal line and to the second outermost electrode via a second signal line that is separate from the first signal line, apply the common voltage to the plurality of electrodes during the display driving mode of a second frame, and apply the touch scan signal to the second group and a second adjacent electrode unit included in the first group adjacent to the second group during the touch driving mode of the second frame; and a touch circuit configured to generate the touch scan signal.
