Abstract: A method of recognizing a fingerprint is implemented by dividing a sensor matrix of a mobile terminal into a plurality of blocks by rows. Each of the blocks is under control of an independent switch terminal. When performing fingerprint unlocking, only an area covered by the fingerprint is being scanned, while an area not covered by the fingerprint is not to be scanned, thereby significantly reducing a scanning area, shortening a scanning time, improving unlocking efficiency, fulfilling fast fingerprint unlocking, and reducing power consumption. A mobile terminal is also provided and includes a multiplexer configured to divide the sensor matrix into a plurality of blocks. Each of the blocks can independently perform fingerprint recognition scanning. When fingerprint unlocking is carried out, there is no need to scan an entire area of the sensor matrix, thereby improving unlocking efficiency and saving electric energy.
