Abstract:
Provided is an optical fingerprint recognition assembly, comprising: a light source and a fingerprint module, wherein the fingerprint module comprises a prism, an image sensor and a fingerprint controller which are packaged together; the prism is provided with a fingerprint contact face for fingerprint pressing; a light source is arranged outside the fingerprint module; light rays emitted from the light source irradiate the fingerprint contact face, on which a fingerprint to be recognized is pressed, and make total reflection with the fingerprint to be recognized; the totally reflected light rays are incident to the image sensor by means of the prism; the image sensor acquires, according to the totally reflected light rays, a fingerprint image; and the fingerprint controller recognizes the fingerprint image sent by the image sensor. The optical fingerprint recognition assembly provided in the present application is provided with the light source and the fingerprint module, that is to say, the optical fingerprint recognition assembly can emit light independently, and when applied to a display apparatus or a mobile terminal, the optical fingerprint recognition assembly emits light by itself rather than emitting light by means of other devices. Also provided is a display apparatus and a mobile terminal.
