Abstract

The invention discloses a fingerprint unlocking method and a related device, and the method comprises the steps: when a first touch operation of a finger for a fingerprint collection area is detected,a TP sends a first interrupt request to an under-screen fingerprint sensor, and sends a second interrupt request to a processor; after the first interrupt request is received, the under-screen fingerprint sensor performs a fingerprint acquisition operation and sends an acquired first fingerprint image to the processor for a fingerprint identification operation; after the second interrupt requestis received, the processor executes a screen awakening operation, and the screen awakening operation adopts a parallel execution mode to shorten the duration required by the screen awakening operation; after the screen awakening operation is completed, the processor controls the touch screen to display a screen locking interface; and when the fingerprint identification is successful, the processorperforms an unlocking operation, and after the unlocking operation is completed, the processor controls the touch screen to display the main interface. By adopting the embodiment of the invention, the problem of splash screen can be solved.

Description

technical field [0001] The present application relates to the field of electronic technology, in particular to a fingerprint unlocking method and related equipment. Background technique [0002] The fingerprint under the area screen is to place the fingerprint sensor under the fingerprint collection area of ​​the touch screen of the mobile terminal (such as smart phone, tablet computer, etc.). At present, in some fingerprint unlocking processes, the time interval between displaying the lock screen interface and displaying the main interface is relatively short, resulting in the problem of flickering screens. Therefore, how to solve the problem of flickering screens is a technical problem that needs to be solved. Contents of the invention [0003] Embodiments of the present application provide a fingerprint unlocking method and related equipment for solving the flickering screen problem. [0004] In the first aspect, an embodiment of the present application provides a fing...
