Embodiment 1

[0039] The invention provides a method for unlocking the screen protection lock of a mobile terminal. see figure 1 , figure 1 It is a flow chart of a preferred embodiment of the method for releasing the screen saver lock of the mobile terminal in the present invention. Such as figure 1 As shown, a method for unlocking the screen saver of a mobile terminal comprises the following steps:

[0040] Step S10, detecting whether the mobile terminal is connected to a charging device.

[0041] In the example of the present invention, the mobile terminal is a terminal with a display screen (screen) as an external input and output device, such as a liquid crystal computer; the display screen can be a CRT display screen, an LCD liquid crystal screen, an LED screen, a projection screen, 3D display screen, etc.; the charging device can be a seat charger, such as a USB charger, a wire charger, such as direct charging of a mobile terminal, emergency charging of a dry battery, etc.

Embodiment 2

[0078] The present invention also provides a system for releasing the screen saver lock of the mobile terminal, such as image 3 as shown, image 3 It is a structural block diagram of the system for unlocking the screen saver of a mobile terminal in the present invention, the system includes a first detection unit 210 , a second detection unit 220 , a comparison unit (not shown in the figure) and a setting unit 230 . Wherein, the first detection unit 210 is connected in parallel to the setting unit 230, and connected in series to the second detection unit 220 to form a closed circuit, one end of the closed circuit is connected to the screen 300, and the other end is connected to the charging device interface 100; One end of the second detection unit 220 is connected to a comparison unit (not shown in the figure), and the first detection unit 210 is connected to the charging device interface 100 , that is, connected to the charging device.

[0079] Further, the setting unit 23...

Embodiment 3

[0084] The present invention also provides a storage medium. The storage medium stores a program for unlocking the screen saver of the mobile terminal. When the program for unlocking the screen saver of the mobile terminal is executed by a processor, it is used to realize the unlocking of the mobile terminal. Method of screen saver lock; specific as above.

Abstract

The invention discloses a method, a system and a storage medium for unlocking a screen saver of a mobile terminal. The method comprises the following steps: detecting whether the mobile terminal is connected with a charging device; after connecting the charging device, detecting a power supply voltage V of a screen, and comparing with a preset threshold V1; if V is smaller than V1, setting an unlocking voltage V2 of the screen, and setting an unlocking current I; setting I as 0, and detecting the power supply voltage V of the screen, and comparing with the preset threshold V1; if V is smallerthan V1, adding a certain value to the unlocking voltage V2 of the screen, until I is set as 0, and the power supply voltage V of the screen is greater than V1. The method is capable of continuously charging the screen unlocking protection voltage through connecting the charging device, enabling the screen power supply voltage to exceed the preset threshold, realizing the automatic unlocking of the screen saver without detaching the screen, and overcoming a problem that the screen overcurrent protection and the disassembly of the mobile terminal with the non-removable screen are inconvenient,and convenient for a user.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to a method, system and storage medium for unlocking a screen protection lock of a mobile terminal. Background technique [0002] Mobile terminals generally use display screens as the main input device. Therefore, the excellent performance of the display screen and the accuracy of data transmission are very important, which will directly affect the user experience. However, in order to adapt to the thinner and thinner mobile terminals As required, accessory screens of mobile terminals also tend to be non-detachable. [0003] However, during the daily use of the mobile terminal, it is inevitable that the mobile terminal will be short-circuited (over-current) due to static electricity, falling, extrusion, etc. Since the screen is also connected to the mobile terminal circuit board, the screen will also be short-circuited instantaneously. At this time, For protection ...
