1. A display device comprising:
a display panel comprising:
a plurality of pixels, each of the plurality of pixels including a light emitting element; and
a plurality of sensors, each of the plurality of sensors including a light sensing element;
a panel driving circuit configured to drive the plurality of pixels;
a readout circuit configured to receive a sensing signal from the plurality of sensors; and
a controller configured to control the panel driving circuit and the readout circuit,
wherein the controller is configured to:
control the panel driving circuit to set a luminance of pixels in an emission area from among the plurality of pixels to a first luminance level in a fingerprint sensing mode; and
control the panel driving circuit to set the luminance of the pixels in the emission area to a second luminance level in a blood pressure sensing mode, and
wherein the second luminance level is higher than the first luminance level.
