Abstract
A display device with an integrated touch screen including 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.
