A display device includes a display panel, an input sensor disposed on the display panel and including a plurality of first sensing electrodes and a plurality of second sensing electrodes, and a sensor controller configured to control the input sensor. The sensor controller receives a first signal from the input sensor and transmits a second signal to the input sensor. The first signal received from the input sensor includes down-link signals from first sensing electrodes corresponding to a first input position and a second input position among the plurality of first sensing electrodes and down-link signals from second sensing electrodes corresponding to the first input position and the second input position among the plurality of second sensing electrodes. The first input position corresponding to a first input source, and the second input position corresponding to a second input source, are spaced apart from each other.
