Abstract

The present application provides a fingerprint module and an electronic device. The fingerprint module includes a casing, a reflection unit, a transmission unit and a sensor module; the reflection unit, the transmission unit and the sensor module are located in the casing; the reflection surface of the reflection unit reflects the light incident through the light inlet hole on the casing to the Transmission unit; the sensor module receives the light signal passing through the transmission unit, and performs fingerprint identification according to the light signal. The present application can improve the accuracy of fingerprint identification.

Description

technical field [0001] The embodiments of the present application relate to fingerprint identification technology, and in particular, to a fingerprint module and an electronic device. Background technique [0002] With the development of fingerprint recognition technology, the traditional physical capacitive fingerprint recognition is gradually replaced, and screen fingerprint recognition has become a technical trend. At the same time, the higher and higher screen ratio can also improve the appearance of electronic devices and the user's visual experience. . [0003] In the screen optical fingerprint identification scheme, the emitted light of the light source is emitted to the finger, and the peaks and valleys of the fingerprint on the finger form light and dark stripes with different brightness on the fingerprint sensor due to the difference in the absorption of the emitted light, that is, the fingerprint image. At present, the optical fingerprint identification scheme ba...
