摘要:
A display device includes light emitting and receiving pixels, a reset line, a fingerprint scan line, a fingerprint sensing line, and first and second voltage lines in a display region. Each light receiving pixel includes a light receiving element including a first electrode and a second electrode connected to the second voltage line, a sensing transistor connecting the first electrode to the fingerprint sensing line according to a fingerprint scan signal applied to the fingerprint scan line and a reset transistor to connect the first voltage line to the first electrode according to a reset signal applied to the reset line. A first voltage applied to the first voltage line is greater than a second voltage applied to the second voltage line, and a third voltage applied to the fingerprint sensing line is greater than the second voltage and smaller than the first voltage.
