Abstract: A display device includes: a display unit; and a sensor unit overlapping with the display unit, and including first sensors, and second sensors crossing the first sensors. During a first frame period, the first sensors are to transmit an uplink signal, and the second sensors are to not transmit the uplink signal, and during a second frame period after the first frame period, the second sensors are to transmit the uplink signal, and the first sensors are to not transmit the uplink signal.

Abstract: A touch sensor includes first touch electrodes, second touch electrodes that form mutual capacitances with the first touch electrodes, and a controller that generates touch data by applying a scan signal to each of scan lines connected to the first touch electrodes during substantially a same time and that receives sensing signals from the second touch electrodes through sensing lines. The controller applies a plurality of multiple pulses and a target pulse as the scan signal to each of the scan lines in a plurality of time periods. Each of the plurality of multiple pulses includes a first pulse and a second pulse of phases opposite to each other. Multiple pulses applied to scan lines adjacent to each other among the scan lines have phases opposite to each other.
