Abstract
A fingerprint identifying system includes a light source, a light-transmissive finger press plate, and an image-capturing unit. The light-transmissive finger press plate is disposed to receive light from the light source, and has a top face adapted to contact a finger, a bottom face, and at least one first microstructure layer formed on at least one of the top and bottom faces of the light-transmissive finger press plate for guiding the light received from the light source to uniformly scatter. The image-capturing unit is disposed below the light-transmissive finger press plate.
