The invention provides an unlocking control method and a relevant product. The relevant product comprises a mobile terminal. The mobile terminal comprises an application processor (AP), a touch display screen and a fingerprint recognition device. The touch display screen is used for acquiring a touch parameter set when it is detected that a user performs sliding operation on the touch display screen, notifying the fingerprint recognition device of carrying out fingerprint acquisition and transmitting the touch parameter set to the AP. The fingerprint recognition device is used for acquiring N fingerprint images and transmitting the N fingerprint images to the AP, wherein N is a positive integer. The AP is used for verifying the touch parameter set and the N fingerprint images and carrying out unlocking operation when verification of the touch parameter set and the N fingerprint images passes. By the adoption of the unlocking control method and the relevant product, the fingerprint images and the touch parameter set can be acquired in the sliding process, the unlocking operation can be carried out only when matching of the fingerprint images and matching of the touch parameter set are achieved, and the security of full-screen fingerprints is improved.

The invention provides a screen backlight adjustment method and a mobile terminal. The screen backlight adjustment method comprises the following steps of: when the mobile terminal opens a fingerprintacquisition function, displaying a mask with a preset color on other areas except a fingerprint recognition area in a display screen; and when the mobile terminal closes the fingerprint acquisition function, controlling the mask to be hidden. According to the screen backlight adjustment method, lights transmitted from other areas except the fingerprint recognition area are weakened through the mask, so that the backlight brightness of the other areas except the fingerprint recognition area is reduced, the area of a high-brightness area on the display screen is reduced, local backlight adjustment of the screen is realized, the optical fingerprint recognition rate is ensured and the problem of dazzling caused by high brightness of the whole display screen is lightened. Moreover, when the fingerprint acquisition function is closed, the mask is controlled to be hidden, so that the mask is prevented from influencing the normal display of the display screen.

The invention provides a fingerprint identification method and a mobile terminal. The method comprises the following steps: if a touch operation on the screen of the mobile terminal is detected, identifying the touch area of the touch operation on the screen of the mobile terminal; if a detection result shows that the mobile terminal is under a state that a fingerprint is to be authenticated, controlling the luminance value of the touch area to be greater than or equal to a first preset luminance value, and controlling the luminance value of the display area except the touch area on the screenof the mobile terminal to be smaller than the first preset luminance value; utilizing a fingerprint identification module to collect and identify the fingerprint information of the touch area. Through the fingerprint identification method provided by the invention, the power consumption of the mobile terminal can be lowered while a high fingerprint identification rate is guaranteed, and the endurance time of the mobile terminal is prolonged.
