Embodiment Construction

[0060] When setting the fingerprint identification module on the LCD screen, the setting method can be found in figure 1 As shown, the liquid crystal display includes a protective cover 1 and a liquid crystal display panel. The liquid crystal display panel includes: a color filter substrate, an array substrate 4 and a liquid crystal layer 3 arranged between the color filter substrate and the array substrate 4. The color filter substrate includes a A plurality of filter layers 2 on the substrate and a black matrix 6 separating two adjacent filter layers 2, an opening 7 is opened on the black matrix (Black Matrix, BM) 6, and the opening 7 is arranged directly below Fingerprint recognition module 5, fingerprint recognition module 5 is a plurality, wherein, because fingerprint is made up of crest 9 and trough 8, so part fingerprint recognition module 5 in multiple fingerprint recognition module 5 is mainly used for fingerprint trough 8 position The reflected fingerprint light form...

Abstract

The embodiment of the invention relates to a liquid crystal display screen and electronic equipment, in particular to a liquid crystal display screen with a fingerprint recognition function. A collimation layer located above a fingerprint recognition module is additionally arranged in a liquid crystal display panel; the shading layer and the fingerprint recognition module are respectively positioned on two sides of the collimation layer; therefore, the situation that the fingerprint information received by the single fingerprint recognition module contains trough information and crest information is reduced or even avoided, the fingerprint information received by a single fingerprint recognition module is relatively concentrated, filtering of noise signals is facilitated, the signal-to-noise ratio of the fingerprint recognition module is effectively increased, the recognition performance of the fingerprint recognition module is enhanced, and the problem of poor fingerprint recognitionperformance caused by low signal-to-noise ratio of a single fingerprint recognition module in an existing liquid crystal display device is solved.

Description

technical field [0001] The embodiment of the present application relates to the field of display technology, and in particular to a liquid crystal display and electronic equipment with a fingerprint identification module. Background technique [0002] With the development of biometric technology, more and more terminals are equipped with biometric modules (such as optical fingerprint recognition modules, iris recognition modules or face recognition modules), among which, the specific work of biometric modules The principle is: the sensor in the biometric module receives the light reflected by the living body and forms a skin characteristic image, compares the skin characteristic image with the stored image, and completes functions such as fingerprint recognition and living body detection. [0003] At present, the optical fingerprint identification module is often installed under the Liquid Crystal Display (LCD) or in the LCD display when setting the terminal. For example, th...
