Provided is a display device including a substrate including a fingerprint area. The fingerprint area includes a first area and a second area. A light-emitting element layer is disposed on the substrate. The light-emitting element layer includes light-emitting elements. A sensor layer is disposed on the substrate, the sensor layer including photosensors. The light-emitting elements include a first light-emitting element arranged in the first area and a second light-emitting element arranged in the second area. During a fingerprint sensing period, the first light-emitting element emits light and the second light-emitting element does not emit light.

Display device including a fingerprint sensor

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.

Fingerprint sensing method, fingerprint sensor, and display device including the same

A display device includes a display panel including a plurality of pixels configured to display an image, a photo sensor on one surface of the display panel to sense light, and a fingerprint detector configured to control a fake determination image pattern of a fingerprint sensing area of the display panel configured to sense a fingerprint, and to perform fingerprint authentication and fake fingerprint determination, based on a sensing signal supplied from the photo sensor.
