Title:
OPTICAL FINGERPRINT IDENTIFICATION MODULE AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/133479
Kind Code:
A1
Abstract:
The present application provides an optical fingerprint identification module and an electronic device. The optical fingerprint identification module comprises: an optical sensor element (302) and an optical element (301), wherein the optical element (301) is provided with a plurality of parallel optical holes (3011), such that a portion of light reflected by a finger is refracted by a prism structure of a backlight module (10), passes through the optical holes (3011), and enters a sensing region of the optical sensor element (302). The invention enlarges the field of view and improves the quality of fingerprint imaging, thereby improving the precision of fingerprint identification.
