Title:
FINGERPRINT IDENTIFICATION APPARATUS AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/036102
Kind Code:
A1
Abstract:
Disclosed in embodiments of the present application are a fingerprint identification apparatus and an electronic device, capable of improving the performance of fingerprint identification apparatuses. The fingerprint identification apparatus is suitable for use under a display screen to achieve under-screen optical fingerprint identification. The fingerprint identification apparatus comprises multiple fingerprint identification units. Each fingerprint identification unit comprises: a microlens; at least two light barrier layers, each of which is provided with a light transmitting hole(s) to form three light guide channels in different directions; and three pixel units, respectively located at the bottoms of the three light guide channels. After fingerprint optical signals returned from a finger above the display screen are converged by the microlens, three target fingerprint optical signals in different directions are respectively transmitted to the three pixel units through the three light guide channels. Three pixel units in each of multiple groups in the fingerprint identification apparatus receive three fingerprint optical signals in different directions and convert same to form three fingerprint images, the three fingerprint images are moved and reconstructed into a reconstructed image, and the reconstructed image is used for fingerprint identification.
