WIPO Patent Application WO/2017/118029
Kind Code:
A1
Abstract:
An optical fingerprint sensor module comprises: a protection layer; an optical fingerprint sensor located under the protection layer, the optical fingerprint sensor having a light transmitting substrate and a device layer, the device layer having a plurality of pixels, each of the pixels 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 device layer; a backlight area light source located under the optical fingerprint sensor, the device layer being located between the backlight area light source and the light transmitting substrate, or the light transmitting substrate being located between the backlight area light source and the device layer; wherein at least one of a light concentrating layer and a light collimating layer is further included between the optical fingerprint sensor and the backlight area light source, the light concentrating layer and the light collimating layer reducing the range of an angle of a transmitted light.
