Abstract
A display device includes a display panel configured to display an image, a sensing panel configured to at least partially overlap 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. 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.
