The composition and structure of the LED display

Even when we don't realize it, LED display has become a part of our daily lives. There are many different places around us, such as airports, shopping malls, sports fields and billboards, which you can see every day without taking into account the components and structure of the LED display. There are many considerations for designing and building impressive video walls. Here, we will discuss the basic composition and structure of LED displays. They combine engineering and creativity perfectly.

The LED display consists of three parts: the main display LED, the content source, and the controller. The display consists of several LED display unit boards, which are connected to each other to form the main body of the led display. Once connected to all cell boards, content can be displayed seamlessly. The control system can be divided into video processors and video control systems, respectively, hardware and software. Light-emitting diode controllers have different functions, depending on the size of the display, the content of the light source, and the usage requirements. Content sources can be input devices such as computers, cameras, DVD players, and so on.

Screen Structure

The screen contains several different components that work together to bring content to the audience. Like motor vehicles, they come in different shapes and sizes, but all have the same basic components. Both indoors and outdoors, LED displays are made up of separate LED displays. Light-emitting diode panels include racks, power supplies, send and receive cards, and LED modules. Each module includes diodes, drive IC and PCB.

Light-emitting diode panels are connected to each other to produce connected light-emitting diodes. The console receives the content and sends a signal to the LED panel. If the aspect ratio of the source content and display is different, the content needs to be adjusted according to the source and controller. The video wall made up of all these LED displays can be used for a variety of purposes.
