1. A display device comprising:
a display panel including a plurality of pixels and a plurality of sensors, each of the plurality of pixels includes a light emitting element, the plurality of sensors include first sensors disposed in a first area and second sensors disposed in a second area, each of the plurality of sensors includes a light receiving element;
a scan driver configured to supply a plurality of scan signals to the plurality of pixels and the plurality of sensors; and
a readout circuit configured to:
in response to the plurality of scan signals,
receive a first sensing signal from the first sensors;
receive a second sensing signal from the second sensors; and
remove noise from the first sensing signal using the second sensing signal to produce a final sensing signal.
