Abstract
An optical fingerprint module comprises: an optical fingerprint sensor, the optical fingerprint sensor having a non-opaque substrate and a device layer located on a surface of the non-opaque substrate, the device layer having a pixel area, the pixel area having a plurality of pixels, each pixel having a non-opaque area and a light blocking area, the light blocking area having a photosensitive element, the non-opaque area enabling lights to transmit through the pixel area of the device layer; a protection layer located above the optical fingerprint sensor; and a backlight source located under the pixel area, an included angle formed between a light emitted from the backlight source and an upper surface of the protection layer being an acute angle. The optical fingerprint module has an improved structure and enhanced performance.
