Embodiment Construction

[0029] It can be seen from the background art that the fingerprint imaging module in the prior art has the problem of poor concealment setting effect. Now combine the structure of a fingerprint imaging module to analyze the reasons for its poor hidden setting effect:

[0030] The optical fingerprint imaging module mainly includes: protective cover, optical sensor, integrated chip (IC), flexible circuit board (FPC) and electronic devices on the flexible circuit board (including light source LED), light guide plate, upper protective shell and Lower protective shell and other main components. Among them, the optical sensor is made on a glass substrate by using semiconductor technology such as amorphous silicon thin film transistor (a-Si TFT), low temperature polysilicon thin film transistor (LTPS TFT) or oxide semiconductor thin film transistor (OS TFT); after cutting , dispensing, bonding and other processes to achieve packaging.

[0031] refer to figure 1 , shows a schematic...

Abstract

The invention relates to a fingerprint imaging module and electronic equipment. The fingerprint imaging module comprises a light source for generating initial light; a waveguide layer which is arranged at one side of the light source and used for transmitting the initial light and scattering part of the initial light to form incident light; a sensing surface, wherein reflected light carrying fingerprint information is formed on the sensing surface by the incident light; and an image sensor for acquiring the reflected light to obtain a fingerprint image. By adopting the technical scheme, the hidden setting effect of the fingerprint imaging module can be effectively increased, so that benefit is brought to improve the aesthetic degree of the electronic equipment.

Description

technical field [0001] The invention relates to the field of fingerprint imaging, in particular to a fingerprint imaging module and electronic equipment. Background technique [0002] Fingerprint recognition technology collects the fingerprint image of the human body through the fingerprint imaging sensor, and then compares it with the existing fingerprint imaging information in the fingerprint recognition system to realize identity recognition. Due to the convenience of use and the uniqueness of human fingerprints, fingerprint recognition technology has been widely used in various fields, such as: public security bureaus, customs and other security inspection fields, building access control systems, and consumer products such as personal computers and mobile phones, etc. [0003] The imaging methods used in fingerprint identification technology include optical, capacitive, ultrasonic and other technologies. One of them is to collect the fingerprint image of the human body ...
