Problems solved by technology

There are three main ways to realize fingerprint recognition: capacitive, optical and ultrasonic. The capacitive signal is very small when the distance between the finger and the sensor electrode is more than 300 μm, and the signal cannot be read. The solid capacitive fingerprint recognition is generally used In the home button, such as the non-display area, there is no good solution for ultrasonic waves due to the excessive media in the display area. Optical fingerprint recognition is a solution that is better integrated in the display.

Abstract

The invention relates to the field of display, and provides a full screen fingerprint identification OLED module group and fingerprint identification method and a display device. The full screen fingerprint identification OLED module group comprises an array substrate which comprises a switch array and a light-emitting unit array which is arranged on the switch array; multiple point light sourceswhich are arranged on the array substrate and used for emitting light to different areas of the fingers at different time to be reflected by the fingers; and a photosensitive sensor which is arrangedin the array substrate and used for receiving the light reflected by the fingers so as to identify the fingerprints. According to the full screen fingerprint identification OLED module group, acquisition of the whole fingerprint information is realized through time-sharing and partitioning control of the light sources in the effective display area; and the point light sources are used as the lightsources without confusion of the light so that the valley ridge can be clearly distinguished and the fingerprint identification efficiency and accuracy can be enhanced.

Description

technical field [0001] The present disclosure relates to the display field, and in particular to a full-screen fingerprint recognition OLED module, a method for identifying fingerprints using the full-screen fingerprint recognition OLED module, and a display device including the full-screen fingerprint recognition OLED module. Background technique [0002] Fingerprint identification refers to identity identification by comparing the detailed feature points of different fingerprints. Because everyone's fingerprints are different, even between the ten fingers of the same person, there are obvious differences in fingerprints, so fingerprints can be used for identification. There are three main ways to realize fingerprint recognition: capacitive, optical and ultrasonic. The capacitive signal is very small when the distance between the finger and the sensor electrode is more than 300 μm, and the signal cannot be read. The solid capacitive fingerprint recognition is generally used...
