Abstract

The invention discloses an LED display screen power supply control circuit and a control method thereof. The LED display screen power supply control circuit comprises a central processing unit, a power supply management module, a power supply assembly, an LED driving module, LED fault detection modules and an LED display screen assembly, wherein the power supply assembly is separately connected with the central processing unit, the LED display screen assembly and the power supply management module through wires. According to the invention, the LED driving module is controlled through the central processing unit; the running state of an LED display screen unit can be independently controlled through each LED driving unit; the picture display of each independent component of the LED displayscreen assembly is effectively realized such that a plurality of pictures can be displayed at the same time and abundant display content is achieved; the LED display unit and a power supply unit whichare associated with each other can be timely monitored in real time through the power supply management module and each LED fault detection unit, and the associated abnormal LED driving unit, LED display screen unit and power supply unit are disconnected, so that the normal operation of other parts is not influenced.

Description

technical field [0001] The invention belongs to the technical field of power supply control, and in particular relates to a LED display screen power supply control circuit and a control method thereof. Background technique [0002] The LED display is a flat panel display consisting of small LED module panels. During the display process of the LED display, usually a display can only display one picture, which is powered by a power control circuit, and when an abnormality occurs in a certain area, it will affect the display of the overall content, and it is also impossible to judge the abnormal part , which brings great troubles to equipment maintenance. Contents of the invention [0003] The object of the present invention is to provide a LED display power supply control circuit and a control method thereof, so as to solve the problems raised in the above-mentioned background technology. [0004] To achieve the above object, the present invention provides the following te...
