The sensor includes a first area and a second area and is configured to sense light transmitted through the display panel. The optical filter is between the display panel and sensor, and overlaps with the first area but not the second area. The optical filter blocks light corresponding to a first wavelength range in a wavelength range of the light. The fingerprint detector determine whether a fingerprint is a fake fingerprint or a pre-registered fingerprint based on a first sensing signal and a second sensing signal. The first sensing signal correspond to an area in contact with a finger in the second area, and the second sensing signal corresponds to an area not in contact with the finger among sensing signals from the sensor."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Fingerprint authentication device, display device including the same, and method of authenticating fingerprint","description":"A display device includes a sensor on a display panel, an optical filter, and a fingerprint detector.
