Beschreibung
Zusammenfassung:	A display device is disclosed that has a touch sensor, which includes a display panel, an integrated driving circuit, a common voltage ring line, and a common voltage feedback line. The integrated driving circuit outputs a touch driving signal and a display common voltage for respectively driving a touchscreen and the display panel. The integrated driving circuit outputs the display common voltage through a common voltage ring pad in a period in which the display panel is driven and outputs a load-free common voltage having a form different from that of the display common voltage through the common voltage ring pad in a period in which the touchscreen is driven.
