Embodiment Construction

[0042] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0043] In related technologies, mobile terminals generally have a screen locking function. The user can unlock the screen by inputting a character password or a graphic password. In order to further protect the security of the mobile terminal and maintain the user's personal privacy, the mobile terminal provides a function of unlocking the screen with a fingerprint. Such as figure 1...

Abstract

The present disclosure relates to a device and method for unlocking a screen, which are used to improve the image transmission method, so as to improve the image display effect. The device includes: a fingerprint recognition sensor, a processing module, and a memory; the memory is used to store preset sample fingerprint information; the fingerprint recognition sensor is used to obtain fingerprint information, send an interrupt to the processing module, and send an interrupt to the processing module. The processing module sends the acquired fingerprint information; the processing module is configured to start under the trigger of an interrupt, and compare the received fingerprint information with the stored sample fingerprint information, and compare When matched, light up and unlock the screen.

Description

technical field [0001] The present disclosure relates to the fields of communication and computer processing, and in particular to a device and method for unlocking a screen. Background technique [0002] With the development of electronic technology, mobile terminals have been widely used, and the replacement is very fast. From the initial keyboard input, to touch screen input, to more advanced various sensor controls, the mobile terminal makes the process of unlocking the screen more and more simple and convenient. Mobile terminals provide people with various services, such as taking pictures and playing music. For example, when controlling to take a photo, you can click the photo button to take a photo, or you can use the voice of "photograph" to control the photo. When playing a song, the next song can be controlled by clicking a button, or the next song can be controlled by shaking the mobile terminal (that is, using gravity sensing). [0003] The inventors of the pr...
