Embodiment Construction

[0036] It can be seen from the background art that the fingerprint imaging module with touch function in the prior art has the problem of unstable trigger success rate.

[0037] refer to figure 1 , shows a schematic cross-sectional structure of a fingerprint imaging module.

[0038] Such as figure 1 As shown, the fingerprint imaging module is an ultra-thin optical fingerprint imaging module. The fingerprint imaging module realizes fingerprint imaging through the principle of photoelectric conversion, including: a light source 11 , an optical area sensor 12 located on the light source 11 , and a protective layer 13 located on the optical area sensor 12 .

[0039] When collecting fingerprints, the finger 10 is pressed on the protective layer 13; the incident light generated by the light source 11 is reflected and transmitted at the contact interface between the finger 10 and the protective layer 13; the formed reflected light passes through the protective layer 13 and is proje...

Abstract

The invention relates to a fingerprint imaging module and electronic equipment. The fingerprint imaging module comprises an image sensor for obtaining fingerprint images; a touch light source which isarranged on the image sensor and used for generating touch detection light; a waveguide layer which is arranged at one side of the touch light source and on the image sensor and used for transmittingthe touch detection light; and a touch detector which is arranged at the other side of the waveguide layer and opposite to the touch light source and used for detecting the light intensity of the touch detection light transmitted through the waveguide layer and controlling the image sensor to obtain the fingerprint images when the light intensity of the touch detection light is reduced. Accordingto the technical scheme, the module disclosed by the invention has the advantages that the success rate of finger detection can be effectively increased and benefit is brought to improve the successrate of triggering a touch function; and the false touch phenomenon can be effectively reduced and benefit is brought to improve the performance of 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] 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 ...
