Problems solved by technology

However, when the contact between the finger and the display screen is not ideal, the difference between the reflectance of the ridges illuminated by light and the reflectance of the valleys illuminated by light is not very large, resulting in inaccurate fingerprint recognition and reducing the fingerprint recognition rate.

Embodiment Construction

[0024] The technical solutions of the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0025] The embodiment of the present application provides a fingerprint processing method electronic device. The electronic device may be a mobile phone, a tablet computer, a notebook computer, a media player, etc., or a financial terminal device such as an automated teller machine (ATM).

[0026] See figure 1 with figure 2 The present application provides an electronic device 200, which includes a display screen 100 and a fingerprint sensor module 40. The display screen 100 has a front 101 facing the user and a back 102 opposite to the front 101. The fingerprint sensor module 40 is fixed on the back 102 of the display screen 100. The fingerprint sensor module 40 obtains a user fingerprint detection signal through the display screen 100.

[0027] The present application also pro...

Abstract

The invention provides a fingerprint processing method and electronic equipment, and the method comprises the steps: determining a pressing region of a user finger when a fingerprint collection request is detected; determining a signal receiving area of the fingerprint sensing module according to the pressing area; receiving a fingerprint detection signal through the signal receiving area; the fingerprint sensing module collecting a specific angle signal in the fingerprint detection signal and shielding a non-specific angle signal, forming a fingerprint image through processing; wherein the fingerprint detection signal is formed by entering a finger of a user through an initial detection signal and emitting the initial detection signal through an area where the finger is in contact with the electronic device, the specific angle signal is formed by emitting a fingerprint ridge area, and the non-specific angle signal is formed by emitting a fingerprint valley area. The fingerprint sensing module only collects the signal of the fingerprint ridge area, so that the information of the fingerprint ridge can still be accurately identified under the condition that the difference between the semaphore of the fingerprint ridge area and the semaphore of the valley area is small, and the fingerprint identification rate is improved.

Description

Technical field [0001] This application relates to the technical field of fingerprint identification, and specifically relates to fingerprint processing methods and electronic equipment. Background technique [0002] At present, the mobile phone collects fingerprints by comparing the area where the ridge of the fingerprint is illuminated by light and the area where the display is in contact with the display, and the valley where the fingerprint illuminates is opposite to the display. Compare the reflectivity of the ridge and the valley where the light illuminates. Identify user fingerprints. However, when the contact between the finger and the display screen is not ideal, the difference between the reflectance at the ridge of the light and the valley where the light is irradiated is not very large, which leads to inaccurate fingerprint recognition and reduces the fingerprint recognition rate. Summary of the invention [0003] This application provides a fingerprint processing met...
