Abstract

The invention discloses an optical fingerprint identification module. The optical fingerprint identification module comprises a circuit board, an optical fingerprint sensor and a light source. An optical fingerprint sensor and a light source are located on the circuit board. The light emitted by the light source is blue and green. A light source is configured to emit light to that optical fingerprint sensor. The optical fingerprint sensor is configured to conduct light emitted from the light source to the outside of the optical fingerprint identification module and to receive light emitted from the light source reflected from the outside of the optical fingerprint identification module. In addition, the invention also discloses an electronic device, which has an optical fingerprint identification module. The optical fingerprint identification module of the embodiment of the invention adopts blue-green light as a sensitive light source, which increases the proportion of blue-green lightin the light received by the optical fingerprint sensor, thereby reducing the interference of ambient light so as to enable the optical fingerprint identification module to obtain a clear fingerprintimage. The optical fingerprint identification module of the embodiment of the invention adopts the blue-green light as a sensitive light source, thereby increasing the proportion of blue-green lightin the light received by the optical fingerprint sensor.

Description

technical field [0001] The invention relates to the technical field of biological identification, in particular to an optical fingerprint identification module and an electronic device. Background technique [0002] Visible light is used as the light source in the optical fingerprint identification module of the related art, and the visible light has a wide wavelength range and can be seen everywhere. The optical fingerprint identification module is easily disturbed by external ambient light during use, so that a clear fingerprint image cannot be obtained, resulting in fingerprint The recognition effect is poor. Contents of the invention [0003] Embodiments of the present invention provide an optical fingerprint identification module and an electronic device.
