    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.
