    Abstract: 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.

    Abstract: A display device comprises a display panel which comprises scan lines, sensing lines, pixels electrically connected to each of the scan lines, and photo sensors electrically to each of the scan lines and the sensing lines, a scan driver which outputs scan signals to the scan lines according to a scan control signal, a timing controller which outputs the scan control signal to the scan driver, and a readout circuit which receives light sensing signals of the photo sensors from the sensing lines. The timing controller sets a frame frequency of the scan control signal to a first frame frequency in a first mode in which the display panel displays an image. The timing controller sets the frame frequency of the scan control signal to a second frame frequency in a second mode in which the photo sensors sense a fingerprint.
