Embodiment Construction

[0029] It can be seen from the background technology that the existing fingerprint imaging module is prone to the problem of difficulty in finding the position of the module in a dark environment. Now combine the structure of a fingerprint imaging module to analyze the reasons why it is difficult to locate in a dark environment:

[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 achi...

Abstract

The invention provides a fingerprint imaging module group and electronic equipment. The fingerprint imaging module group comprises a light source which is used for producing incident light; a light-emitting layer which is used for transmission of the incident light and storing the luminous energy of a part of the incident light and also used for producing indicating light according to the stored luminous energy; a sensing surface on which the reflected light carrying the fingerprint information is formed through the incident light transmitting through the light-emitting layer; and an image sensor which is used for acquiring the reflected light so as to acquire the fingerprint image. According to the technical scheme, when fingerprint sensing is not performed, the fingerprint imaging modulegroup is enabled to emit light by the light-emitting layer so that the indicating light can realize the indicating effect under the dark condition and realize the function of indicating the positionof the fingerprint imaging module group, and thus the user experience can be improved.

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] The imaging methods of the imaging module used in the fingerprint identification technology include optical, capacitive, ultrasonic and other technologies. One of them is to collect t...
