Document Type and Number:
WIPO Patent Application WO/2017/118030
Kind Code:
A1
Abstract:
An optical fingerprint sensor module comprises: an optical fingerprint sensor (320), the optical fingerprint sensor (320) having a light transmitting substrate (322) and a device layer located on a surface of the light transmitting substrate (322), the device layer having a pixel area (321), the pixel area (321) having a plurality of pixels, each pixel having a light transmitting area and a non-light-transmitting area, the non-light-transmitting area having a photosensitive element, the light transmitting area enabling lights to transmit through the pixel area (321) of the device layer; a protection layer (310) located above the entire optical fingerprint sensor (320); and a backlight source (330) located right under the pixel area (321), the backlight source (330) and the optical fingerprint sensor (320) being spaced apart with an interval, an included angle formed between a light emitted from the backlight source (330) and an upper surface of the protection layer (310) being mainly a right angle or approximately a right angle. The optical fingerprint sensor module has an improved structure and enhanced performance.
