When the fingerprint pattern is matched with the pre-stored fingerprint pattern, first information for indicating successful identification is generated. When the fingerprint pattern is compared with the pre-stored fingerprint pattern, When the pre-stored fingerprint pattern does not match, second information is generated to indicate that the recognition has failed.
The fingerprint recognition method according to claim 8, wherein:

When the fill light includes a plurality of light emitting diodes, the step of controlling the fill light to be turned on includes:

And controlling a part of the plurality of light emitting diodes to light up.
A terminal device, comprising a processor, a memory, and a computer program stored on the memory and executable on the processor, and when the computer program is executed by the processor, the method according to claim 8 or 9 is implemented. The steps of the fingerprint identification method.
A computer-readable storage medium having stored thereon a computer program, wherein when the computer program is executed by a processor, the steps of the fingerprint recognition method according to claim 8 or 9 are implemented.
