In general, a screen using an LED is a display device that has excellent resolution and realizes color images of various colors, and is installed in various forms on an exterior wall or inside of a building for advertisement or broadcasting, and is used to implement images or videos.

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

In other words, the LED screen is composed of hundreds of thousands of elements and semiconductor components, and accordingly, there is a high possibility that the display surface will be scratched due to component defects during operation of the LED screen. In this way, if a scratch occurs on the display surface of the LED screen, the defect cannot be resolved until the engineer visits the site and replaces the component block on the display surface.

Accordingly, there is a need for a method that can quickly resolve the defective state of the LED screen, and Patent Registration No. 10-1201294 (information display system) has a plurality of main driving ICs and a plurality of sub driving ICs, and a plurality of main driving ICs are provided. This is a technology for periodically polling the IC to detect a faulty main driving IC among the main driving ICs, replacing it with a sub driving IC, and activating the sub driving IC.

However, the prior art has a disadvantage in that a very complex circuit must be formed between the control unit and the plurality of main driving ICs because the control unit polls each of the plurality of main driving ICs in parallel. In addition, when a failure occurs in the main driving IC, since the sub driving IC is replaced with a sub driving IC, the elements constituting the main driving IC must always pass a current close to the rated current, and thus, there is a problem that the aging phenomenon is intensified.

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

In addition, in the sound system transmitted through the LED screen, sound is transmitted through a speaker through a fixed stand microphone or an individually provided hand microphone.

It can be used safely by connecting it with a hanger, and it has the feature that the LED screen can be conveniently installed using a hanger.

However, the conventional LED display board is a structure in which a plurality of LED modules are combined with a cabinet and the cabinet is conveniently connected with one touch. Since the sound system and the image system must be separately constructed, many people use microphones. In this case, there is a problem in that the LED screen that displays the image between the person using the microphone directly and the person waiting for the microphone is separated, causing an unbalance between the display of the LED screen and the sound. There is also a problem that viewers who watch the LED display screen experience discomfort because they cannot track the creator or the instrument.
