Power supply control method and device of display screen and storage medium

Abstract

The invention discloses a power supply control method and device of a display screen and a storage medium. The power supply control method and device is applied to a mobile terminal. The mobile terminal comprises the display screen and a power supply, wherein the display screen is provided with a signal input end, the power supply is electrically connected with the signal input end so as to provide a driving voltage to the display screen, whether an input current exceeds a preset current threshold or not is judged by determining an input current at the signal input end, the continuous time when the input current exceeds the preset current threshold is detected if the input current exceeds the preset current threshold, electrical connection between the power supply and the signal input endis cut off when the continuous time is larger preset time, so that the power supply can be timely cut off according to an abnormal phenomenon of a power supply current of the display screen, the display screen is effectively prevented from being circuit-shorted, and the damage rate of the display screen is reduced. The method is simple and is high in practical.

Description

technical field [0001] The present application relates to the field of communication technology, and in particular to a method, device and storage medium for controlling power supply of a display screen. Background technique [0002] With the development of mobile communication, the popularity of smart phones is getting higher and higher, and their functions are becoming more and more powerful. However, with the powerful functions of mobile phones, the requirements for the performance of the mobile phone display and the motherboard are also getting higher and higher. [0003] In order to achieve the best display effect, existing smartphones use large-size, high-definition, high-resolution display screens, and the control logic for controlling the display screens in the motherboard is relatively complicated, which is prone to control logic errors. When the control logic of the display screen is wrong, the driving voltage and current received by the display screen will be inco...

[0003] In order to achieve the best display effect, existing smartphones use large-size, high-definition, high-resolution display screens, and the control logic for controlling the display screens in the motherboard is relatively complicated, which is prone to control logic errors. When the control logic of the display screen is wrong, the driving voltage and current received by the display screen will be incorrect. After a long time, it will easily lead to a short circuit of the peripheral control circuit attached to the display screen, and eventually this part of the display screen will be damaged and cannot be displayed.
