Embodiment Construction

[0071] The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings.

[0072] 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.

[0073] 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 (...

Abstract

The invention provides an under-screen biological identification and an electronic device. The under-screen biological identification device comprises: a lens which is disposed under a display screento receive an optical signal returned from the upper portion of the display screen via a human finger, a lens barrel, an optical filter, and a sensing chip wherein the optical signal is used to detectbiological identification information of the finger; the lens is fixed in the lens barrel; the optical filter is located under the lens; the sensing chip is disposed under the lens barrel, and is used for imaging based on an optical signal passing through the lens; and a distance between a photosensitive surface of the sensing chip and an imaging surface of the lens is greater than or equal to apreset value. The under-screen biological identification device and the electronic device provided by the embodiments of the present application can improve the efficiency of under-screen biological identification recognition.

Description

technical field [0001] The present application relates to the field of biometric identification, and more particularly, relates to an off-screen biometric identification device and electronic equipment. Background technique [0002] With the rapid development of the electronic equipment industry, especially the rapid development of mobile communication equipment (such as mobile phones), biometric technology has attracted more and more attention. More convenient off-screen biometric technology, such as off-screen fingerprint recognition technology Practicality has become what the public needs. [0003] At present, the optical fingerprint recognition technology under the screen mainly includes the optical fingerprint recognition technology under the screen based on the periodic microhole array and the optical fingerprint recognition technology under the screen based on the integrated microlens. The former optical fingerprint recognition technology is easily affected by Moiré ...
