Even when we are not aware of it, LED display has become a part of our daily life. There are many different places around us, such as airports, large shopping malls, sports fields and billboards. You can see them every day, regardless of the components and structure of the LED display. There are many considerations for designing and building an impressive video wall. Here, we will discuss the basic composition and structure of LED displays. They perfectly combine engineering and creativity.

The LED display includes three parts: the main display LED, content source and controller. The display includes several LED display unit boards, which are connected to each other to form the main body of the LED display. After connecting to all unit boards, the content can be displayed seamlessly. The control system can be divided into two parts: the video processor and the video control system, which are hardware and software. The LED controller has different functions, depending on the size of the display, the content of the light source and the requirements for use. The content source can be input devices such as computers, camcorders, and DVD players.

Screen structure

This screen contains several different components that work together to bring content to the audience. Like motor vehicles, they have different shapes and sizes, but they all have the same basic components. Whether indoor or outdoor, the LED display is composed of an independent LED display. The light-emitting diode panel includes a rack, a power supply, a transceiver card and an LED module. Each module includes diode, driver IC and PCB.

The light-emitting diode panels are connected to each other to produce mutually connected light-emitting diodes. The console receives the content and sends a signal to the LED panel. If the source content and the displayed aspect ratio are different, you need to adjust the content according to the source and controller. The video wall composed of all these LED displays can be used for multiple purposes.
