Claim 0:
1. A display device comprising:
a display panel configured to display an image;
a sensing panel that at least partially overlaps the display panel and that includes a sensing area and a non-sensing area;
a sensing panel controller configured to drive the sensing panel;
a plurality of sensing electrodes disposed in the sensing area; and
a plurality of sensing lines electrically connected to the plurality of sensing electrodes, respectively,
wherein the sensing panel controller is configured to apply the same sensing voltage to each of the plurality of sensing lines or to apply a reference voltage different from the sensing voltage to at least some sensing lines among the plurality of sensing lines,
wherein the plurality of sensing lines are positioned to extend in one direction in the sensing area and the non-sensing area,
wherein the sensing area includes a first sensing area, a second sensing area, and a third sensing area divided in a direction perpendicular to a direction in which the plurality of sensing lines are dense, and
wherein the sensing panel controller is configured to sequentially divide and drive the first sensing area, the second sensing area, and the third sensing area.
