Abstract
A fingerprint identification assembly includes a laminated lens having a first lens, a second lens and a third lens formed together with the first lens and the second lens, each of the first lens, the second lens and the third lens has a dielectric film coated thereon. At least one illuminator is located at a bottom of the laminated lens and a sensor located under the laminated lens for picking up an image of a fingerprint on top of the laminated lens. The dielectric film of the laminated lens allows light from the at least one illuminator to be partially reflected due to the fingerprint on the laminated lens and partially penetrates through the second lens and the third lens to be picked up by the sensor.
