▎ 摘  要

NOVELTY - The device comprises one fingerprint sensing element (20). The fingerprint sensing element is used to collect a users fingerprint. A graphene pressure sensitive layer is located on the side where the sensing surface of the fingerprint sensing element is located, alternatively, it is located on the side of the fingerprint sensing element away from its sensing surface. The graphene pressure-sensitive layer is used to deform under the touch pressure applied by the user. The graphene pressure-sensitive layer has multiple sensing sub-blocks arranged at intervals. Each sensing sub-block corresponds to one fingerprint sensing element. USE - Fingerprint identification device in an electronic device and a shell assembly (all claimed). ADVANTAGE - Reduces the probability of ghost-touching when the electronic apparatus is being used by a user. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) an electronic device that comprises a fingerprint identification device; and (2) a shell assembly that comprises a middleframe and the fingerprint identification device. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of an electronic device that has the fingerprint identification module.
