Embodiment Construction
[0050] figure 1 A schematic diagram and partially enlarged schematic diagram of a fingerprint sensing module according to the first embodiment of the present invention. Please refer to figure 1 , the fingerprint sensing module 100 is suitable for sensing the fingerprint 60 of the finger of the subject 50, and the fingerprint sensing module 100 includes a sensing element 110, an optical cover 130, and is disposed between the optical cover 130 and the sensing element 110. The optical alignment layer 120. The sensing element 110 includes a sensing surface 111 , and the optical alignment layer 120 covers the sensing surface 111 . In other words, in the fingerprint sensing module 100 of this embodiment, the light beam is suitable for passing from the optical cover 130 to the sensing element 110 , and the light beam needs to pass through the optical collimation layer 120 before being passed to the sensing element 110 .
[0051] The optical alignment layer 120 of this embodiment i...
