Abstract

The invention relates to the technical field of fingerprint identification, and provides a fingerprint identification module. The fingerprint identification module comprises a backboard, a light source, a photoelectric receptor and a fingerprint identification switch; the light source is arranged on the backboard, the light source can emit infrared light and visible light, and a fingerprint can reflect the infrared light to form infrared reflected light; the photoelectric receptor is arranged on the backboard and used for detecting the luminous intensity distribution of the infrared reflectedlight and identifying a wave peak and wave trough of the fingerprint; and the fingerprint identification switch is arranged on the backboard and used for controlling the light source and the switchingon or switching off of the photoelectric receptor. The fingerprint identification is clearer by using the fingerprint identification module; display and fingerprint identification do not affect eachother and cannot affect the display effect.

Description

technical field [0001] The invention relates to the technical field of fingerprint identification, in particular to a fingerprint identification module and a fingerprint identification device. Background technique [0002] With the development of science and technology, fingerprint recognition technology has been widely used in many fields such as mobile terminals and smart homes. Especially on mobile terminals, in-screen fingerprint recognition methods or comprehensive fingerprint recognition methods have been studied. [0003] At present, the mainstream fingerprint recognition technologies include photoelectric fingerprint recognition, capacitive fingerprint recognition and ultrasonic fingerprint recognition. Capacitive fingerprint recognition uses commonly used capacitive sensors to analyze touch objects, and it is difficult to achieve full-screen fingerprint recognition. Photoelectric fingerprint recognition includes: micro light emitting diode combined with optical se...
