DISPLAY DEVICE WITH INTEGRATED TOUCH SCREEN AND METHOD FOR DRIVING THE SAME
First Claim
1. A display device with an integrated touch screen, comprising:
- a display panel including electrodes divided into a plurality of block type groups and a plurality of data lines;
a display driver IC configured to apply a common voltage to the electrodes when a driving mode of the panel is a display driving mode, sequentially apply a touch scan signal to each block type group when the driving mode of the panel is a touch driving mode, and apply a data signal to the data lines associated with a corresponding block type group when the touch scan signal is applied to the corresponding block type group; and
a touch IC configured to generate the touch scan signal and apply the touch scan signal to the display driver IC.

11. A method of controlling a display device with an integrated touch screen, the method comprising:
-
dividing electrodes included in a display panel of the display device into a plurality of block type groups and a plurality of data lines; applying, via a display driver IC of the display device, a common voltage to the electrodes when a driving mode of the panel is a display driving mode; sequentially applying, via the display driver IC, a touch scan signal to each block type group when the driving mode of the panel is a touch driving mode, and applying a data signal to the data lines associated with a corresponding block type group when the touch scan signal is applied to the corresponding block type group; and generating, via a touch IC of the display device, the touch scan signal and apply the touch scan signal to the display driver IC. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
