Abstract: A display panel includes an array substrate, a protective cover, a fingerprint identification circuit, and an optical structure. The array substrate and the protective cover are disposed oppositely, where the protective cover is located at a light exiting side of the array substrate. The fingerprint identification circuit is located at a side of the array substrate facing away or toward the protective cover and is configured to receive detection light and perform a fingerprint detection according to the detection light. The optical structure is located at a side of the protective cover facing away from the array substrate and is configured to increase a reflection amount of the detection light received by the fingerprint identification circuit.
