Abstract
A display screen is provided, including a display layer and a first light shielding layer. The display layer has a display surface, the first light shielding layer is arranged on the display surface and has a fingerprint recognition area, the fingerprint recognition area includes at least one first through hole sensing signals emitted and received by a fingerprint unit located below the display screen can be transmitted through the first through hole. A display device is provided, including the display screen and an optical fingerprint unit. The optical fingerprint unit is disposed at a side of the display layer away from the first light shielding layer and located at a position corresponding to an optical fingerprint recognition area. The fingerprint unit includes a light emitter and a light inductor, and a light signal emitted by the light emitter is transmitted to a fingerprint and received by the light inductor after being reflected by the fingerprint. A mobile terminal is provided.
