Summary:Embodiments of this application provide an electronic device. The electronic device includes a middle frame, a display, and a fingerprint recognition module. An optical waveguide structure is disposed between the display and the fingerprint recognition module. An optical exit port and at least two optical incident port are formed on the optical waveguide structure. The optical exit port is directly aligned with the fingerprint recognition module. Each optical incident port is directly aligned with a fingerprint recognition area. When a finger touches the fingerprint recognition area to reflect out fingerprint detection light, the fingerprint detection light can be incident into the optical waveguide structure through the optical incident port, and be exported to the fingerprint recognition module through the optical exit port, to implement fingerprint recognition. In this way, there are at least two fingerprint recognition areas of the electronic device. When the electronic device only verifies a fingerprint of one finger to complete the fingerprint recognition, a user can choose to press one area that is easily touched in a plurality of fingerprint recognition areas. This is convenient to operate, and a problem of inconvenient operation caused by that the user can only touch an only fingerprint recognition area is resolved.
