Abstract:
1. A display device integrated with a touch screen, comprising: a touch panel comprising a touch electrode which is disposed in each of a plurality of pixels defined by intersections between a plurality of gate lines and a plurality of data lines; a display driver configured to supply data voltages through the data lines to the respective pixels, wherein during a display period, the display driver is configured to supply data voltages for displaying an image to the respective pixels; wherein during a touch sensing period subsequent to the display period, the display driver is configured to supply an initialization data voltage to each pixel before detecting a touched position, wherein the initialization data voltage initializes a capacitance of the touch electrode; and a touch driver configured to sense the capacitance of the touch electrode to detect the touched position during the touch sensing period after the display driver has supplied the initialization data voltage to each pixel, wherein the touch electrode is driven as a common electrode during the display period.
