Abstract

The invention discloses a fingerprint identification system and electronic equipment, and the fingerprint identification system is used for the fingerprint identification of a liquid crystal display module with a backlight part. The liquid crystal display module is provided with a fingerprint identification area for placing a finger; the fingerprint identification system comprises an emitter usedfor emitting an optical signal to the fingerprint identification area. The fingerprint identification system comprises: an emitter used for emitting an optical signal to the fingerprint identificationarea, wherein the emitter is not shielded by the backlight component; the wavelength of the light emitted by the emitter is beyond the wavelength range of the light emitted by the backlight component; a receiver, wherein the receiver is used for receiving the fingerprint identification signal, and the receiver is shielded by the backlight component. The fingerprint identification system and the electronic equipment can realize fingerprint identification of the screen liquid crystal display module.

Description

technical field [0001] The present application relates to the field of fingerprint identification, in particular to a fingerprint identification system and electronic equipment. Background technique [0002] With the development of biometric technology, under-screen fingerprint recognition technology has been widely used in portable mobile terminals such as mobile phones. At present, taking mobile phone screens as an example, according to different types of light sources, they are mainly divided into: Liquid Crystal Display (LCM for short) screens and Organic Light-Emitting Diode (OLED for short) screens. [0003] In order to improve screen utilization and pursue a larger screen-to-body ratio, the OLED screen has realized a full-screen fingerprint recognition function. However, for the LCM screen, since the LCM is a passive light emitting mode, a backlight source is required for display. The backlight is a light source located behind the LCD module, its luminous effect wil...
