Abstract

The embodiment of the invention relates to the technical field of electron, in particular to a method for lighting up a screen and a mobile terminal. The method includes the following steps of: judging whether a fingerprint sensor acquires fingerprint data or not; and if the fingerprint sensor acquires the fingerprint data, lighting up the screen of the mobile terminal. The embodiment of the invention judges whether the fingerprint sensor acquires the fingerprint data or not and lights up the screen of the mobile terminal if the fingerprint sensor acquires the fingerprint data, so that the screen can be lighted up without frequently pressing down a power key, the using times of the power key are reduced and the service life of the power key is prolonged.

Description

technical field [0001] Embodiments of the present invention relate to the field of electronic technology, and in particular, to a method for lighting a screen and a mobile terminal. Background technique [0002] With the development of mobile communication technology, intelligent mobile terminals such as smartphones and tablet computers have developed rapidly, and have become an important part of people's life and entertainment. People generally use these devices to surf the Internet, entertain, communicate, and so on. [0003] In current mobile terminals, the screen is usually turned on by pressing the power button. However, frequently pressing the power button to turn on the screen will easily damage the power button. Contents of the invention [0004] In order to solve the above technical problems, embodiments of the present invention provide a method for lighting up a screen and a mobile terminal. [0005] On the one hand, an embodiment of the present invention provid...
