Optical Fingerprint Module

Abstract

An optical fingerprint module, including: an optical fingerprint sensor; a point backlight source; the optical fingerprint sensor includes and only includes a non-opaque substrate; the first surface of the non-opaque substrate being directly used for fingerprinting contact; the second surface of the non-opaque substrate includes a device layer; the device layer includes a pixel area; the pixel area includes a plurality of pixels; each of the pixels includes a non-opaque area and a light-blocking area; and the light-blocking area includes a photosensitive device formed therein; the non-opaque area allows light to pass through the pixel area of the device layer; the point backlight source is disposed below the pixel area, and an angle between the light emitted from the point backlight source and the first surface of the non-opaque substrate is acute. The structure of the optical fingerprint module is simplified and the performance is improved.
