FINGERPRINT SENSING MODULE
First Claim
1. A fingerprint sensing module, adapted to sense a fingerprint of a finger of a user, the fingerprint sensing module comprising:
- a sensing device, comprising a sensing surface;
an optical-collimating layer, covering the sensing surface, and comprising a plurality of light-blocking areas and a plurality of light-transmitting areas, wherein each of the light-transmitting areas is surrounded by a part of the light-blocking areas; and
an optical cover, disposed on the optical-collimating layer, the optical-collimating layer being disposed between the optical cover and the sensing device, and the optical cover being adapted to contact the finger of the user, wherein the optical cover is adapted to transmit a sensing light from the finger of the user to the optical-collimating layer, and the light-blocking areas are adapted to block a portion of the sensing light, and another portion of the sensing light is transmitted to the sensing surface through the light-transmitting areas.

Abstract
A fingerprint sensing module adapted to sense fingerprint of user'"'"'s finger is provided. The fingerprint sensing module includes a sensing device, an optical cover and an optical-collimating layer located between the sensing device and the optical cover. The sensing device includes a sensing surface, and the optical-collimating layer covers the sensing surface. The optical-collimating layer includes light-blocking areas and light-transmitting areas, and each of the light-transmitting area is surrounded by a part of the light-blocking areas. The optical cover is disposed on the optical-collimating layer, and the optical cover is adapted to contact the user'"'"'s finger, and the optical cover is adapted to transmit a sensing light from the user'"'"'s finger to the optical-collimating layer, and the light-blocking areas are adapted to block a portion of the sensing light, and another portion of the sensing light is transmitted to the sensing surface through the light-transmitting areas.
