Fingerprint identification device, fingerprint identification module and control method of fingerprint identification device

A fingerprint identification module, comprising:

• a substrate;
• a fingerprint identification sensor, disposed on the substrate and configured to receive fingerprint information about a finger of a user;
• and
• a driving assembly, disposed on the substrate;
• wherein when the finger is placed on the fingerprint identification module, the driving assembly is configured to deform according to a control signal to drive the fingerprint identification sensor so that the fingerprint identification sensor is sequentially moved relative to the substrate in different directions.

A control method of a fingerprint identification device, comprising:

• when a user's a finger is placed on the fingerprint identification device, receiving, by a fingerprint identification sensor, fingerprint information about the finger, wherein the fingerprint identification sensor is in an initial position;
• outputting, by a control circuit, a control signal to a driving assembly;
• driving, by the driving assembly, the fingerprint identification sensor to sequentially move relative to the initial position according to the control signal;
• and
• receiving, by the fingerprint identification sensor, other pieces of fingerprint information about the finger when the fingerprint identification sensor sequentially moves relative to the initial position;
• wherein the step of driving, by the driving assembly, the fingerprint identification sensor to sequentially move relative to the initial position according to the control signal comprises driving the fingerprint identification sensor by the driving assembly to move relative to the initial position in a first axis and a second axis.
