Abstract

The invention provides an under-screen optical fingerprint module and a fingerprint identification mobile terminal, and relates to the technical field of fingerprint identification. The under-screen optical fingerprint module comprises a fixed lens cone, a mobile lens group, a mobile controller and a fingerprint chip attached to a mainboard; the mobile lens group is movably assembled in the fixedlens cone, the fixed lens cone is arranged outside the fingerprint chip in a surrounding manner, the mobile lens group is arranged above the fingerprint chip, and the mobile controller is arranged inthe fixed lens cone, is in transmission connection with the mobile lens group and is used for driving the mobile lens group to move relative to the fingerprint chip. Compared with the prior art, a plurality of devices such as a support, a motor and a conventional lens are omitted, the fixed lens cone is integrated, the structure is simple, and the problems that an original focusing scheme is complex in structure, high in process difficulty, multiple in procedure and the like are solved. A focusing mode can be better realized, the clewest state of the image can be captured, and the fingerprintidentification capability and the safety of safety unlocking can be better improved.

Description

technical field [0001] The invention relates to the technical field of fingerprint identification, in particular to an under-screen optical fingerprint module and a fingerprint identification mobile terminal. Background technique [0002] With the continuous change of mobile phone unlocking methods, from the initial digital password, pattern, to fingerprint, face, iris, biometric unlocking methods are constantly changing. While the technology is constantly breaking through, the convenience of mobile phone unlocking And the security has also been greatly improved. Nowadays, the most attention-grabbing off-screen fingerprints are also constantly updated. The off-screen fingerprints are mainly optical, and the optical fingerprint mode has gradually become the master of the under-screen fingerprint recognition. The optical type is divided into integrated type, separate type and focusing type. At present, the effect of the focusing type has not been significantly improved and imp...
