Abstract
The present application relates to the field of biometric identification technologies, and provides an under-screen optical fingerprint identification device and an electronic apparatus with the under-screen optical fingerprint identification device. The under-screen optical fingerprint identification device comprises a reflecting component, a lens and a fingerprint sensor; the reflecting component, the lens and the fingerprint sensor are provided on a fingerprint detection light path of the under-screen optical fingerprint identification device; the lens is provided on a reflection path of the reflecting component, and is configured to converge fingerprint light reflected by the reflecting component to the fingerprint sensor; an incident angle of the fingerprint light on the display screen is greater than or equal to a preset angle, the fingerprint light being reflected by a finger to the display screen and entering the fingerprint sensor through the fingerprint detection light path.
