Embodiment Construction

[0044] The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings.

[0045] As electronic devices enter the era of full screens, the fingerprint collection area on the front of electronic devices is squeezed by the full screen, so the under-display or under-screen fingerprint recognition technology has attracted more and more attention. The fingerprint recognition technology under the screen refers to installing the fingerprint recognition module (such as the fingerprint recognition module) under the display screen, so as to realize the fingerprint recognition operation in the display area of ​​the display screen. Area Set the fingerprint collection area.

[0046]Optical under-screen fingerprint recognition technology uses light returning from the top surface of the device's display assembly for fingerprint sensing and other sensing operations. The returned light carries information of an object (s...

Abstract

The embodiment of the present invention discloses a fingerprint identification device and an electronic device. The fingerprint identification device is applied to an electronic device having a display screen, the fingerprint recognition device comprising an optical fingerprint sensor module, wherein the optical fingerprint sensor module is configured to be disposed under the display screen such that the fingerprint collection area is at least partially located in the display area of the display screen. The optical fingerprint sensor module comprises a plurality of sensor chips, and the sensing areas of the plurality of sensor chips respectively correspond to a plurality of sub-areas in the fingerprint collection area, wherein each sensor chip is used for detecting optical signals from above their corresponding sub-areas. The technical solution of the embodiment can improve the user experience in the fingerprint identification process and simultaneously improve the security of fingerprint recognition.

Description

technical field [0001] The embodiments of the present application relate to the technical field of fingerprint identification, and more specifically, to 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 fingerprint recognition technology under the optical screen is to use the fingerprint sensor to collect the light emitted by the light source and reflect the reflected light formed by the finger. The reflected light carries the fingerprint information of the finger, so as to realize the fingerprint recognition under the screen. When performing fingerprint identification, a specific guide icon will be displayed on the display screen corresponding to the position where the fingerprint...
