Abstract: A display device includes a display unit displaying an image, a fingerprint sensing unit disposed on one surface of the display unit and including fingerprint sensing pixels to sense a fingerprint, and a readout circuit providing a selection signal to the fingerprint sensing unit to select a predetermined amount of fingerprint sensing pixels from the fingerprint sensing pixels as a sensing area and receiving a fingerprint sensing signal from the sensing area. The readout circuit accumulates the fingerprint sensing signal provided from the fingerprint sensing pixels in the sensing area during a test mode and calculates a compensation value based on a difference between the accumulated fingerprint sensing signal and a reference value.
