Title
(EN) An optical fingerprint recognition module and an electronic device
(ZH) 光学指纹识别模组及电子设备
Abstract
(EN)
An optical fingerprint recognition module and an electronic device are provided. The optical fingerprint recognition module includes: an optical sensing element (302) and an optical element (301). Theoptical element (301) has a plurality of optical holes (3011) parallel to each other such that refracted light obtained after light reflected by a ginger is refracted by a prism structure of a backlight module (10) can pass through the optical holes (3011) and enter a sensing area of the optical sensing element (302). Through the optical fingerprint recognition module and the electronic device, the imaging field is enlarged, quality of fingerprint imaging is improved, and fingerprint recognition accuracy is higher.
