TECHNICAL FIELD

The present disclosure generally relates to a field of electronic device technologies, and particularly to an electronic device, and a method for processing a fingerprint image and related products.

BACKGROUND

With the widespread application of electronic devices (such as mobile phones, tablet computers, etc.), the electronic devices can support more and more applications, with more and more powerful functions. The electronic devices are developing in a diversified and personalized direction and become indispensable to users' lives.

Fingerprint recognition technology has become a standard technology of electronic devices. With the development of fingerprint recognition technology, optical fingerprint identification module is popular currently.

SUMMARY

Embodiments of the present disclosure provide an electronic device. The electronic device includes a screen provided with a first polarizer, a second polarizer and an optical fingerprint identification module, the second polarizer being arranged below the screen, and the optical fingerprint identification module being arranged below the second polarizer. A polarization direction of the first polarizer is the same with the polarization direction of the second polarizer. The first polarizer and the second polarizer are both configured to filter a first optical noise from a screen light of the screen and directing to the optical fingerprint identification module. The second polarizer is configured to filter a second optical noise from screen light of the screen, directing away from the optical fingerprint identification module and reflected by a glass cover on an outer side of the screen.

Embodiments of the present disclosure provide a method for processing a fingerprint image. The method is applied to an electronic device. The electronic device includes a screen provided with a first polarizer, a second polarizer, and an optical fingerprint identification module. The second polarizer is arranged below the screen. The optical fingerprint identification module is arranged below the second polarizer. A polarization direction of the first polarizer is the same with the polarization direction of the second polarizer. The method includes: turning on the screen to emit light and activating the optical fingerprint identification module in response to a fingerprint collection instruction, in which a first optical noise from a screen light of the screen and directing to the optical fingerprint identification module is filtered by both the first polarizer and the second polarizer, a second optical noise from the screen light of the screen, directing away from the optical fingerprint identification module and reflected by a glass cover on an outer side of the screen is filtered by the second polarizer; and collecting a reflected light of the screen light reflected by a user fingerprint through the optical fingerprint identification module and acquiring a fingerprint image after processing the reflected light.

Embodiments of the present disclosure provide an electronic device. The electronic device includes a processor, a memory, a screen provided with a first polarizer, a second polarizer, and an optical fingerprint identification module. The second polarizer is arranged below the screen. The optical fingerprint identification module is arranged below the second polarizer. A polarization direction of the first polarizer is the same with the polarization direction of the second polarizer. The one or more programs are stored in the memory and configured to include instructions for executing a method for processing a fingerprint image. The method includes: turning on the screen to emit light and activating the optical fingerprint identification module in response to a fingerprint collection instruction, in which a first optical noise from a screen light of the screen and directing to the optical fingerprint identification module is filtered by both the first polarizer and the second polarizer, a second optical noise from the screen light of the screen, directing away from the optical fingerprint identification module and reflected by a glass cover on an outer side of the screen is filtered by the second polarizer; and collecting a reflected light of the screen light reflected by a user fingerprint through the optical fingerprint identification module and acquiring a fingerprint image after processing the reflected light.
