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 system for inspecting thin glass includes: a housing including a body and a cover; a first shuttle which fixes an edge portion of the thin glass and reciprocates in a first axis direction; a first inspection part disposed on the body and which measures a position of a defect formed in the thin glass by taking a picture of the thin glass; a transport shuttle which separates the thin glass from the first shuttle, a second shuttle which separates the thin glass from the transport shuttle, fixes the thin glass, and reciprocates the upper surface of the body; and a second inspection part disposed on the body and spaced apart from the first inspection part and which inspects the position of the defect by taking an enlarged picture of the position of the defect. The first shuttle tensions and fixes the thin glass.

Abstract: A method for restoring an image of a fingerprint sensor is described. The method includes capturing, by the fingerprint sensor, a fake fingerprint image from a fake fingerprint; calculating a phase of the fake fingerprint from the fake fingerprint image; capturing a plurality of target fingerprint images at measurement times by a fingerprint sensor disposed on a rear side of a display panel; applying the calculated phase to each of the acquired target fingerprint images; and combining information from each of the plurality of target fingerprint images to generate a final fingerprint image.
