Abstract:
The present application relates to a fingerprint identification module and a display device. The fingerprint identification module includes: a first lens assembly; a second lens assembly with a primary optical axis not parallel to a primary optical axis of the first lens assembly; a reflecting mirror assembly, including a reflecting mirror and a rotating shaft coupled to the reflecting mirror, wherein the rotating shaft can drive the reflecting mirror to rotate, and the reflecting mirror includes a reflecting surface; and a light-sensitive element located at a light exiting side of the second lens assembly. The first lens assembly converges fingerprint-reflected light and projects the fingerprint-reflected light onto the reflecting surface, the reflecting surface reflects the fingerprint-reflected light to the second lens assembly, the second lens assembly converges the fingerprint-reflected light to the light-sensitive element, the light-sensitive element converts the fingerprint-reflected light into an electrical signal to identify fingerprint information.
