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.
