LED displays have become a massive part of the global market, with the industry expecting to grow up to 19.5 billion USD by 2026, which is a 21 percent increase from the numbers reported in 2022. These screens have become a part of people’s daily lives, whether they’re on the billboards of massive highways to the ones found on the exterior of the malls and other commercial buildings. This is how important an LED screen structure is.
An LED display or screen is a visual device that uses light-emitting diodes in order to produce colors that can form text, images, and videos. The LED module is wrapped by an LED display structure, along with its components that can protect the entire ensemble.
If you’re planning on investing in LED displays, learning about the LED screen structure is one of the tasks you need to include in your to-do list. You need to look at all the components and the possible issues you might encounter with the LED display. Does it simply refer to steel structure for LED screens or does it mean more? Start with the fundamentals, from definitions and basic compositions.
What Is An LED Screen Structure?
An LED screen structure refers to the entire ensemble that makes up the LED display. Most of the time, it refers to the outer cover of the LED display that can support it wherever you plan to install the screens. Technically, it is the realization of practical engineering and boundless creativity. Ultimately, the key to understanding an LED display structure relies on what kind of LED display you’re looking at.
For an impressively massive video wall, the durable skeleton that holds all the screens together may be considered as the structure. Whether it’s a frame, a cabinet, or a mount, all of these elements can be identified as LED screen structures. In general and to have an all-encompassing definition, the structure refers to all the elements that allow the LED screens to operate. The term is not only limited to the steel structure for LED screens.
Three Basic Components of An LED Screen Structure
LED displays can be one solid LED screen or an ensemble of several LED modules put together to form an entirely new LED display, regardless of the shapes and sizes. One of the vital topics you have to learn in an LED display structure is the basic components that comprise the ensemble. With the LED display, there are three basic components to look at:
The LED panel is also known as the LED cabinet, it is the main hardware of the LED screen structure. Multiple panels can be used to construct a single LED display showing unified content and connected to one controller. Here are some of the elements that often make up an LED panel:
- LED modules (Diodes, PCB, and IC drivers)
- LED frame or cabinet
- Power supply
- Sending and receiving cards
- Flat cables
- DC5v cables for LED module
- DC5V cable for receiving card
These LED modules are designed to be scalable, which means that there are only very few elements that can hinder you from creating a massive LED screen for full audience impact – budget and creativity.
Despite having multiple screens, the entire ensemble can operate as one or show different content unified to a single cause.
In the LED screen structure, the LED panel is wired to the LED controller. The controller is responsible for managing all the LED modules that will be used. It often has two parts, which are the following:
- Control Board (Video Processor) – This is the hardware component of an LED controller, which often includes a computer and sending and receiving cards. It receives the signal from the content source to show the right videos and images.
- Video Control System – This is the software component of the LED control, which helps the video processor function effectively.
The features and functions of LED controllers rely heavily on the content, size of the LED display, and the application specifications.
Similar to the LED display, the content source is also wired to the LED controller. It is the component of the LED screen structure responsible for carrying the content that needs to be shown. It can be stored in a camera, PC, or DVD player. The content source sends out the signal to the controller so that the correct content will be used.
Computers and DVD players can show prepared content like images and video clips. If it’s real-time and live content (like in concerts or sports events), cameras are often needed.
Detailed Structure of An LED Screen
If you want a detailed look at all the elements that make up the components of an LED screen structure, here is a summary you can look at.
The LED modules make up the entire LED display unit. It is considered a small drive light circuit that is supported by LED lights, PDB boards, and drive ICs. They are responsible for producing light that can recreate images to be displayed on the screen.
LED Display Frame
The LED display frame is often confused with the LED screen structure. The frame is responsible for making sure that the LED modules are stable and fixed in the area where they’re supposed to stay put. Most often, it is the steel structure for LED screens. While stainless steel is popular, the frame can also be made from other materials like iron, plastic board, or AI alloy.
LED Controller (Control System)
The LED controller is the central control system of the entire ensemble. It can also be called the scanning control board since it is responsible for processing the signals it receives from the content source and sending the processed data to the LED modules.
The content source is one of the key components of the LED screen structure, which can come in the form of devices like computers and cameras. The content can be stored as a file in other places like Blu-ray discs and flash drives. If an internet connection is on, you can also get the content and run it from the cloud or other online storage like OneDrive or Google Drive.
LED display structure often uses a switching power supply that helps regulate and convert the voltage. It can easily convert 110V or 220V to other kinds of direct current needed for the LED display to operate and function even when using other types of circuits.
Cables & Connections
There are several types of cables and connections used in the LED screen structure, including the following:
- DC5v cable: which is used to power LED modules;
- Flat cable: which transmits the signal from the receiving card to the LED module;
- Ethernet cable uses a computer to transmit to the sending box, and then the sending box transmits to the cabinet, and the signal is transmitted between the cabinet and the cabinet;
- AC cable: For AC power supply
Sending box or card: It receives signals from computers, cameras, DVDs, etc., processes and transmits them to the box;
Receiving card: It is a signal transmission component installed in the box
How to Choose the Right LED Screen Structure
When choosing the ideal LED screen structure, it is necessary to consider all three components that make up the ensemble and all the other elements under these components. Here are some useful tips you can follow to choose the right one.
- Make sure that all these components are compatible with each other, especially when dealing with cables and cards
- Choose a well-balanced, safe, and durable LED framework for the display’s foundation
- Consider the LED display’s size and shape when choosing a cabinet or mount
- Check on the cables if they are in good condition and if possible choose shorter cables to guarantee seamless operation
- Look into your content and check if the resolution of the image or video will match the resolution and size of the LED screen
LED screen structures can be associated in two ways – it can either be the entire ensemble of the LED display or it can be the framework that holds all the LED panels in position. The LED display structure has three major components that make it possible for the LED screen to operate and function. Under these components, other elements support them. Missing just one component can be a total disaster and hinder the display screen from operating.
The steel structure for LED screens is only a part of the entire LED screen structure. The frame can come as a mount, a cabinet, or an entire screen skeletal framework, depending on the LED display. Make sure that you know the difference between these two types of LED display structures.
