Abstract: A display device includes a light-emitting pixel and a sensor pixel. The light-emitting pixel includes a light-emitting element, a first transistor electrically connected between a first line and a second line and configured to control a driving current flowing through the light-emitting element in response to a voltage of a first node, and a second transistor connected between the first node and a third line. The sensor pixel includes a light-receiving element connected between a sensor node and the second line, and a first sensor transistor configured to control a current flowing between the third line and a readout line in response to a voltage of the sensor node.

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.
