With the increasing functions of mobile phones of terminal equipment, more and more new functions of the terminal equipment bring more convenience to users. At present, the fingerprint recognition function is favored by manufacturers of large terminal devices. At present, when a fingerprint identification function is designed for terminal equipment such as a mobile phone, a tablet personal computer and the like, a physical key is basically adopted to combine the fingerprint identification function, so that the purpose of compatibility of key and fingerprint identification is achieved, when a certain stroke is reached, the physical key 02 is triggered, a system can identify two actions of a fingerprint and a key, and then corresponding actions are extracted according to upper-layer requirements. However, the above structure not only affects the aesthetic appearance of the whole terminal device, but also affects the convenience of user operation. The fingerprint identification device under the screen can be arranged in the display screen of the mobile phone, and can realize large-area fingerprint identification without being limited to a specific size, which is equivalent to increasing the length of a password and improving the safety of fingerprint identification. However, a longer fingerprint matching time is required for large-area fingerprint identification, which causes a larger power consumption of the terminal device and affects user experience.

step 1: acquiring fingerprint information of the user collected by the plurality of fingerprint sensors,
step 2: and determining the effectively pressed fingerprint sensor in the plurality of fingerprint sensors according to the fingerprint information of the user.
And step 3: if the effective fingerprint appears twice or more, the unlocking is successful;
and 4, step 4: if the effective fingerprint does not appear, prompting the user to try again;
and 5: and if the effective fingerprint does not appear after more than three times of attempts, prompting the user to unlock through the password.
In the step 1, each fingerprint sensor corresponds to one induction area, and the induction areas corresponding to the plurality of fingerprint sensors form a fingerprint acquisition area of the under-screen fingerprint acquisition system;
the fingerprint information of the user collected by the effectively pressed fingerprint sensor is used for fingerprint authentication of the user.
