The present invention is an LED display board that implements the image by connecting a plurality of cabinets connected to a plurality of LED modules, the power supplied to the cabinet is divided into a weak electric power to provide a stable power, in the basic power supply In case of abnormal power supply or short circuit of power supply, the power supply is backed up and can be used safely. It can safely supply power and video signals without wiring to the LED module, greatly improving productivity, and The present invention relates to an LED display board having a launch structure in which a power source can be completely eliminated and a power source capable of preventing physical damage or moisture is prevented from being damaged or damaged.

In general, a screen using an LED is a display device having a high resolution and implementing a color image of various colors, and is used to implement an image or a video by installing in various forms on the exterior wall or inside of a building for advertisement or broadcasting.

The LED screen has a unit pixel composed of LED elements (Light Emitting Diodes) emitting red, green, and blue as basic components, and pixels are arranged in a horizontal and vertical matrix to form a single LED module. Chang's LED modules gather to form an LED screen.

In other words, the LED screen is composed of hundreds of thousands of elements and semiconductor components, and thus the possibility of scratching the display surface due to component failure during the operation of the LED screen is very high. In this way, if a scratch occurs on the display surface of the LED screen, the failure state cannot be cleared until the engineer visits the site and replaces the component block on the display surface.

Accordingly, there is a need for a method for quickly eliminating a defective state of the LED screen, and Patent No. 10-1201294 (Information Display System) includes a plurality of main driving ICs and a plurality of sub driving ICs, and includes a plurality of main driving devices. When the IC is periodically polled to detect a faulty main driving IC among the main driving ICs, the IC is replaced with the sub driving IC and the sub driving IC is activated.

However, the conventional technology has a disadvantage in that a very complicated circuit must be formed between the controller and the plurality of main driver ICs because the controller polls each of the plurality of main driver ICs in parallel. In addition, when a failure occurs in the main driving IC, since the sub-driving IC is replaced, the elements constituting the main driving IC should always flow near the rated current, which causes a problem of aging.

Recently, LED screens are enlarged in order to exhibit the maximum visual effect, and various technologies have been developed and released to install and manufacture them.

Korean Patent No. 10-0948976 "LED display board" is provided on the front and outer frame of the outer frame consisting of a horizontal frame formed in parallel with each other on the upper and lower sides facing each other, a vertical frame coupled to each side of the horizontal frame, respectively It is composed of a main frame, a front side of the main frame, a plurality of LEDs are arranged and the LED board and the background block that is selectively coupled to the main frame to form a spaced vent hole to block the background of the main frame have.
