Abstract: A device for verifying a fingerprint includes: a sensing unit which captures a fingerprint image from a fingerprint of a user; a memory which stores a registered fingerprint image; and a controller which calculates a correlation coefficient between at least one region of the fingerprint image and the registered fingerprint image, and rotation-corrects the fingerprint image by a predetermined angle based on a result of comparing the correlation coefficient and a threshold value, where an area of the at least one region is within a range of about 5% to about 40% of an area of the fingerprint image.

Abstract: A display device includes a sensor, a transparent substrate, and a plurality of light emitters adjacent a first side the transparent substrate. The light emitters emit light in a first direction and a second direction opposing the first direction. The sensor senses reflected light, which is emitted through a second side of the transparent substrate and received by the sensor after being reflected from a location outside the display device.
