Problems solved by technology

[0003] The fingerprint identification device needs to be installed under the screen to realize the fingerprint detection function, but the distance between the lower surface of the screen and the upper surface of the fingerprint identification device is difficult to test accurately when leaving the factory, that is, the installation position of the fingerprint identification device is difficult to test accurately. The stage can only ensure that the distance is within a certain range through structural processing technology
In addition, when consumers use it, different people press the screen in thousands of ways, and the difference in pressing force will also cause the distance to fluctuate.

Abstract

The embodiments of the present application disclose a method for fingerprint identification, a fingerprint identification device, and an electronic device, which can improve the quality of a fingerprint image. The method is applicable to an electronic device having a display screen and a fingerprint recognition device disposed below the display screen. The method includes: acquiring an original image generated by the fingerprint recognition device according to the received first oblique optical signal, wherein the first oblique optical signal is an oblique optical signal from the light-emitting unit that points to the fingerprint recognition device; acquiring a smear image generated by the fingerprint recognition device according to the received second oblique light signal, wherein secondoblique optical signal is an oblique optical signal emitted by the light-emitting unit and directed to the surface of the fingerprint recognition device, and then reflected by the surface of the fingerprint recognition device and reflected from the lower surface of the display screen to the fingerprint recognition device; according to the distance X between the original image and the smear image,the fingerprint data collected by the fingerprint recognition device is corrected, wherein the corrected fingerprint data is used for fingerprint recognition.

Description

technical field [0001] The embodiments of the present application relate to the field of fingerprint identification, and more specifically, relate to a method for fingerprint identification, a fingerprint identification device and electronic equipment. Background technique [0002] With the rapid development of the mobile phone industry, people pay more and more attention to fingerprint recognition technology, and the practical application of fingerprint recognition technology under the screen has become the demand of the public. The under-screen optical fingerprint recognition technology is most widely used in the under-screen fingerprint recognition technology. The under-screen optical fingerprint recognition technology can use the light emitted by the screen as the light source. The optical signal carrying fingerprint information will be received by the fingerprint identification device for fingerprint identification. [0003] The fingerprint identification device needs ...
