The invention discloses an optical fingerprint identification assembly, which comprises a light source and a fingerprint module. The fingerprint module comprises a prism, an image sensor and a fingerprint controller, which are packaged together. The prism has a fingerprint contact surface for fingerprint press; the light source is arranged on the outer portion of the fingerprint module; light rays emitted from the light source are irradiated to the fingerprint contact surface pressed by a fingerprint to be identified and have total reflection with the fingerprint to be identified; totally-reflected light rays are incident to the image sensor through the prism; the image sensor obtains a fingerprint image according to the totally-reflected light rays; and the fingerprint controller identifies the fingerprint image sent by the image sensor. The provided optical fingerprint identification assembly has the light source and the fingerprint module, that is, the optical fingerprint identification assembly can emit light independently; and when the optical fingerprint identification assembly is applied to the display device or the mobile terminal, the optical fingerprint identification assembly can emit light independently without help of other devices. The invention also provides the display device and the mobile terminal.
Description
technical field [0001] The invention relates to the field of electronic equipment, in particular to an optical fingerprint identification component, a display device and a mobile terminal. Background technique [0002] With the development of science and technology, at present, mobile phones and tablet computers are mainly unlocked by fingerprints. The existing fingerprint recognition devices are mainly capacitive fingerprint recognition devices, optical fingerprint recognition devices and thermal fingerprint recognition devices, while optical fingerprint recognition devices The device has become the most widely used fingerprint identification device due to factors such as reliable use and low price. [0003] The optical fingerprint identification devices used in mobile terminals in the prior art generally use the organic light-emitting layer of the display screen as light for fingerprint identification. light, its service life is relatively short, which is not conducive to...
