Embodiment Construction

[0032] It can be seen from the background art that in the prior art, after the electronic equipment is equipped with a fingerprint imaging module, the stability, waterproof, dustproof and antistatic performance of the electronic equipment need to be improved. Combining with the schematic diagram of the structure of the electronic equipment, the reason why it is difficult to realize the hidden setting problem is analyzed:

[0033] refer to figure 1 , shows a schematic cross-sectional structure diagram of an electronic device with a fingerprint imaging function.

[0034] The electronic device includes: a protective cover 10 for isolating the hardware of the electronic device from the external environment for protection; a fingerprint optical image sensor 11 located below the protective cover 10 for collecting fingerprint images .

[0035] The fingerprint optical image sensor 11 is a capacitive fingerprint optical image sensor, so in order to reduce the distance between the fin...

Abstract

A fingerprint imaging module and electronic equipment, the fingerprint imaging module includes: a light source for generating incident light, the light source has a light-emitting surface; an optical image sensor located on the light-emitting surface of the light source for transmitting the Incident light; sensing surface, the incident light transmitted through the optical image sensor is reflected on the sensing surface to form reflected light carrying fingerprint information; the optical image sensor is also used to collect the reflected light to obtain fingerprint image. The technical scheme of the invention can realize the concealed setting of the fingerprint imaging module, and is beneficial to improving the waterproof, dustproof and antistatic performance of the electronic equipment equipped with the fingerprint imaging module.

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] The fingerprint identification technology collects the fingerprint image of the human body through the fingerprint imaging module, and then compares it with the existing fingerprint imaging information in the fingerprint identification system to realize identity identification. 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] One of the fingerprint imaging modules used in fingerprint identification technology collects fingerprint images of the human body through optical fingerprint imaging modules: the inci...
