    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.

    Abstract: A display device includes: a display panel; an emission driver; a scan driver; and a timing controller. The display panel includes light emitting pixels and photosensitive pixels, where the photosensitive pixels are operated in an initialization period, a light exposure period and a sensing period. The emission driver supplies emission control signals to emission control lines connected to the light emitting pixels, based on an emission start signal. The scan driver supplies scan signals to scan lines connected to the light emitting pixels and the photosensitive pixels, based on a scan start signal. The timing controller generates the emission start signal having a single pulse of a gate-off level and the scan start signal having a single pulse of a gate-on level in a last frame period among frame periods corresponding to the light exposure period and in each of frame periods corresponding to the sensing period.

    Abstract: A display device includes: a display panel; a scan driver to provide scan signals to scan lines; an emission driver to provide emission control signals to emission control lines; and a readout circuit to receive a sensing signal from a readout line. The display panel includes: a first pixel in a first row, and connected to a first sub-scan line from among the scan lines, and a first emission control line; a first photo sensor in the first row, and connected to the first sub-scan line, a reset control line, and the readout line; a second pixel in a second row, and connected to a second sub-scan line from among the scan lines, and a second emission control line; and a second photo sensor in the second row, and connected to the second sub-scan line, a third emission control line, and the readout line.
