Abstract: A display device including: scan lines including first and second scan lines; pixels connected to the scan lines; photo sensors connected to some of the scan lines, the photo sensors including a first photo sensor connected to the first scan line and a readout line, and a second photo sensor connected to the second scan line and the readout line; a scan driver to provide scan signals to the scan lines; and a readout circuit to receive, through the readout line, detection signals which are outputted from the photo sensors in response to the scan signals, wherein, while the scan signals are provided to the first and second scan lines, the readout circuit samples a detection signal of one of the first photo sensor and the second photo sensor without sampling a detection signal of the other one of the first photo sensor and the second photo sensor.

Abstract: A fingerprint sensor includes a substrate, a light blocking layer that is on a first surface of the substrate and includes openings in a light blocking mask, and a sensor layer that is on a second surface of the substrate and includes photo sensors. A fingerprint sensing method of the fingerprint sensor includes: storing a calibration image; generating an original image, based on sensing signals from the photo sensors; performing calibration on the original image by utilizing the calibration image; and detecting a fingerprint, based on the calibrated image. The calibration image is generated by synthetizing valid regions extracted from an original calibration image corresponding to the original image.

Abstract: A head mounted display device includes a display unit divided into at least one first area and at least one second area, a lens unit which supplies an image displayed on the display unit to a user, and a frame which fixes the display unit and the lens unit thereto. The display unit includes a memory which stores first compensation data corresponding to the first area and second compensation data corresponding to the second area, and a position determiner which determines whether first data supplied from an outside belong to the first area or the second area.
