Embodiment Construction

[0016] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0017] The embodiment of the present invention detects the touch operation received on the screen when the mobile terminal is in the off-screen state, and when the number of touch operations detected within the preset time is the same as the number of pre-stored unlock passwords, it is judged that Whether the touch operation matches the password, and if so, perform a screen unlocking operation. Therefore, when the screen of the mobile terminal is in the off-screen state, the unlocking information input by the user is received, so that the unlocking password is not easy to be peeped by others, and t...

Abstract

The invention, which is applicable to the technical field of mobile terminals, provides a screen unlocking method and a screen unlocking device for mobile terminals. The method includes the following steps: when a mobile terminal is in a state that the screen is turned off, touch operation received on the screen is detected; when the frequency of the touch operation detected within preset time is equal to the number of prestored unlocking passwords, whether the touch operation is matched with the unlocking passwords is judged, and if so, the screen unlocking operation is executed. Since the unlocking information inputted by a user is received when the screen of the mobile terminal is turned off, other people cannot easily peep at the unlocking passwords, and thereby the unlocking security is enhanced; the screen does not need to be lit up when the mobile terminal needs to be unlocked, so the unlocking efficiency is increased.

Description

technical field [0001] The invention belongs to the technical field of mobile terminals, and in particular relates to a screen unlocking method and device for a mobile terminal. Background technique [0002] When an existing mobile terminal unlocks the screen, the screen is first lit, and then an unlock password input by the user on the screen in the lit state is received. Since the screen of the mobile terminal is in a lighted state during the unlocking process, the unlocking password input by the user is easy to be seen by people nearby, so that the unlocking password is leaked, resulting in low unlocking security. Contents of the invention [0003] In view of this, embodiments of the present invention provide a method and device for unlocking a screen of a mobile terminal, so as to solve the problems that the unlock password of the existing mobile terminal is easy to be peeped and the unlocking security is low during the screen unlocking process of the existing mobile t...
