摘要:
A small-thickness low-cost fingerprint recognition apparatus and an electronic terminal are provided. The fingerprint recognition apparatus includes an optical film and an image sensor that are disposed at an interval of a first distance along a first direction. The optical film includes a first area and a second area, transmittances of the first area and the second area are different, the first area and the second area form a first pattern, and when receiving light reflected by a first object, the optical film converts the light into an optical image that has the first pattern and transmits the optical image to the image sensor. The image sensor is configured to receive an optical signal of the optical pattern and convert the optical signal into an electrical signal. The electrical signal is used to construct an image of a surface that is of the first object and that reflects the light. An electronic terminal including the foregoing fingerprint recognition apparatus is provided.
