Abstract
A display device is disclosed that includes a sensor area including a plurality of channels each including touch electrodes arranged in a column, a peripheral area located around the sensor area and including touch lines connected to the channels, and a display driver configured to supply touch driving signals to the channels. The sensor area includes a first sensor area located at a first edge of the sensor area, and a second sensor area located adjacent to the first sensor area. The display driver supplies first touch driving signals having a first voltage level to the channels in the first sensor area during a first period, and supplies second touch driving signals having a second voltage level to the channels in the second sensor area during a second period after the first period, the second voltage level being lower than the first voltage level. The display driver supplies the first touch driving signals sequentially to the channels in the first sensor area according to a single-channel driving scheme during the first period, and supplies the second touch driving signals simultaneously to the channels in the second sensor area according to a multi-channel driving scheme during the second period.
