Abstract: A method for driving a display device is performed by the display device. The method includes: displaying a first image including user convenience information through a display panel; generating sensing data corresponding to a fingerprint sensing area by using a photoelectric sensor; and determining whether a sensed fingerprint corresponding to the sensing data is a fake fingerprint by comparing expected sensing light illuminance information based on the first image with sensed light illuminance information of the sensing data. The first image includes a first color pattern in the fingerprint sensing area of the display panel. A fake-determination image pattern includes the first color pattern and a second color pattern different from the first color pattern.

Abstract: A display device includes a display panel and a fingerprint authentication device disposed under the display panel. The fingerprint authentication device includes a sensor device and an optical filter. The sensor device includes a first area and a second area in a plan view and sensing light passing through the display panel. The optical filter is disposed between the display panel and the sensor device, overlaps the first area and does not overlap the second area in the plan view, and blocks the light of a certain wavelength range.

Abstract: A fingerprint authentication device includes a biometric sensor configured to generate a sensing signal by sensing biometric information, an image processor configured to generate a fingerprint image based on the sensing signal, a singular point determiner circuit configured to select at least one fingerprint piece based on the fingerprint image or the sensing signal, and determine a singular point of the fingerprint image by analyzing the selected at least one fingerprint piece, and an authenticator circuit. The image processor is further configured to extract an interest region including the singular point from the fingerprint image based on a coordinate of the singular point, and the authenticator circuit is configured to perform fingerprint authentication by comparing the interest region with registered fingerprint information.
