Abstract: A display device comprises a display panel comprising an image display area and a non-display area, display pixels comprising light-emitting elements in the image display area and pixel driving units connected to the light-emitting elements, light-sensing pixels comprising photo-detecting units in a fingerprint sensing area in the image display area, and sense driving units connected to the photo-detecting units, a light-sensing reset driver configured to supply reset signals to the sense driving units of the light-sensing pixels for at least each horizontal line among the light-sensing pixels in response to a line select signal from a display driving circuit; and a fingerprint scan driver configured to sequentially supply a fingerprint scan signal to the sense driving units of the light-sensing pixels in response to a fingerprint scan control signal from the display driving circuit.

Abstract: A display device includes: a substrate; scan lines extending in a first direction, and arranged along a second direction crossing the first direction on the substrate; data lines extending in the second direction, and arranged along the first direction on the substrate; a display area including pixels connected to the scan lines and the data lines; and a non-display area around the display area, and including compensation capacitors connected to some scan lines from among the scan lines. A sum of a capacitance of q odd scan lines or q even scan lines that are adjacent to each other from among the scan lines increases in the second direction, where q is a positive integer.

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.
