Embodiment Construction

[0059] As smart terminals enter the era of full screens, the fingerprint collection area on the front of electronic devices is squeezed by the full screen, so under-display or under-screen fingerprint recognition technology has attracted more and more attention. The fingerprint recognition technology under the screen refers to the installation of the fingerprint recognition device under the screen (such as a fingerprint recognition module) under the display screen, so as to realize the fingerprint recognition operation inside the display area of ​​the display screen, and does not need to be on the front of the electronic device except for the display area. Set the fingerprint collection area for the locale.

[0060] The off-screen fingerprint recognition technology may include an off-screen optical fingerprint recognition technology, an off-screen ultrasonic fingerprint recognition technology, or other types of off-screen fingerprint recognition technologies.

[0061] Take the...

Abstract

An embodiment of the invention discloses an under-screen fingerprint identification device and electronic equipment, wherein the device can settle a problem of an influence of an LCD backlight moduleto fingerprint optical imaging and improves fingerprint imaging quality. The under-screen fingerprint identification device is suitable for the electronic equipment with a liquid crystal display screen and comprises the components of a micro-lens array which is used for being arranged below the backlight module of the liquid crystal display screen; at least one light blocking layer which is arranged below the micro-lens array, wherein the light blocking layer has a plurality of light passing small holes; and an optical detecting array which is arranged blow the light blocking layer, wherein the micro-lens array is used for focusing an optical signal in a specific direction of the backlight module to the plurality of light passing small holes and transmits the optical signal in a non-specific direction of the backlight module to the light blocking area of the light blocking layer, wherein the optical signal in the specific direction is transmitted to the optical detecting array throughthe plurality of light passing small holes.

Description

technical field [0001] The present application relates to the field of under-screen fingerprint recognition, and more particularly, relates to an under-screen fingerprint recognition device and electronic equipment. Background technique [0002] With the development of biometric technology, under-screen fingerprint recognition technology is more and more widely used in portable terminals such as mobile phones. Currently, mobile phone screens are mainly classified into liquid crystal display (liquid crystal display, LCD) screens and organic light-emitting diode (organic light-emitting diode, OLED) screens according to types of light sources. Among them, since the OLED screen itself has light-transmitting characteristics, the fingerprint recognition device under the OLED screen can receive the reflected light emitted by the OLED screen itself after being reflected by a finger to detect fingerprints. The LCD screen provides light source through the backlight module, and the va...
