Title:
FINGERPRINT RECOGNITION MODULE AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/140741
Kind Code:
A1
Abstract:
Disclosed are a fingerprint recognition module and a display device, relating to the technical field of displays. The fingerprint recognition module comprises a first lens set (1), a second lens set (3), a reflector set and a photosensitive element (4), wherein a primary optical axis of the second lens set (3) is arranged non-parallel to a primary optical axis of the first lens set (1); the reflector set comprises a reflector (2) and a rotating shaft (5) connected to the reflector (2), wherein the rotating shaft (5) can drive the reflector (2) to rotate, and the reflector (2) comprises a reflective surface, with the reflective surface being located on a light emergent side of the first lens set (1) and a light incident side of the second lens set (3); and the photosensitive element (4) is located on a light emergent side of the second lens set (3). The first lens set (1) is used for converging fingerprint reflected light and projecting the fingerprint reflected light onto the reflective surface, the reflective surface is used for reflecting the fingerprint reflected light to the second lens set (3), the second lens set (3) is used for converging the fingerprint reflected light on the photosensitive element (4), and the photosensitive element (4) is used for converting the fingerprint reflected light into an electrical signal so as to recognize fingerprint information.
