LED displays have played a vital role in many industries today, from simply advertising successes to massive concerts and festivals. Suffice it to say, that LED screens can be a big help for your business in many ways but it’s up to you to maximize their use. This is why it is important to know everything you can about how it operates, even complex concepts and aspects like the LED control system. 

One of the most complicated aspects when dealing with LED displays is its LED display control system. While it may be easier to just purchase LED screens and use them as they are without knowing how they work technically, it is a good idea to have a basic knowledge of how these screens operate and what LED control systems have to do with them. 

Definition of An LED Control System

Complete LED control system

An LED control system can be regarded in two ways, including the entire LED display ensemble or just the computer to the controller. These two aspects of LED displays are responsible for programming the images and videos you want to show. 

For a standard look of an LED display control system, you will see a computer connected to the LED controller, both are responsible for creating the command on what to display on the LED screen, when to display it, and what the specifications are that they need to be displayed in. The technical definition of the LED control system is the unit that handles and manages the data that needs to be displayed, including storage and the processing of signals to transfer it. 

The LED display control system may also only refer to the LED controller, which is the device responsible for the commands needed to send the necessary signal to display the data programmed to be shown. 

Types of LED Control Systems

LED control systems come in two forms. They can either be synchronous or asynchronous, depending on the control card used in the controller. LED display controllers transmit the necessary signal to the LED screen panel. And you can structure your controllers depending on the control card you choose. 

Synchronous LED Control System

A synchronous LED control system offers a more flexible and versatile functionality since it can be used for all kinds of LED displays and all the modes they can be set in. The important thing is to use good LED control software. You can check this out if you want to use it. 

For this type of LED control system, the following elements are available:

  • LED sending and receiving cards
  • LED hub card
  • Brightness multi-function card (Add-on or optional)
  • Humidity adjustment multi-function card (Add-on or optional

Asynchronous LED Control System

Compared to the other type, the asynchronous LED control system is a bit limited at what it can do. It can only be used for specific types of LED display modes, including the following:

  • Pop-up display
  • Roll-up mobile display
  • Roll-down mobile display

LED Control System Basic Structure

The basic structure of an LED control system with LED video processor

In a standard LED control system, there are three basic components involved, including the computer (main control circuit), the LED controller (data distribution circuit), and the LED screen module (LED drive circuit). 


The computer in the LED display control system is responsible for storing the data that will be displayed on the LED screen but there are also instances where the content to be displayed is stored in other places, including the following:

  • Flash drive
  • TV set
  • Cloud
  • Video Camera

These devices will be connected to the computer, which will then connect to the LED display controller using USB or HDMI/DP/DVI cables. This connection will make it possible for the LED control system to operate effectively, with video signals being sent to the appropriate receiver. 

You will need to download and install the LED control software to effectively manage and operate your content using the computer. To secure everything, set an LED control system password that only you and the people who will operate the displays know. 


The LED controller is part of the LED display control system that acts as the middleman between the computer and the LED screen. Also known as an LED control card, it functions as the receiver and sender of image and video signals from the computer toward the LED modules. It is necessary to choose the ideal controller for your needs, along with the proper number of outputs and loading capacity. 

LED Video Processor

If you’re looking for an LED video processor but can’t seem to find any, you may want to look at other names like the following:

  • Image processor/converter
  • Video controller
  • Video format converter
  • Independent video sources

Whether you decide on an LED control system descargar or not, take the time to consider all the parts that will make up your system. With LED video processors, many love to add this element to the LED control system because of the following features it offers:

Image Zooming

Regardless of the size and resolution of the image, you zoom in or out of the full image. This will help you scale the image properly. With this feature, you can be sure that people will see your content in the way you want them to – not halved or not too small either. 

Resolution Conversion

Using the LED video processor, you can convert the signal resolutions of the images to fit the actually physical resolution of the LED display. It also allows you to switch quickly from one input signal to the other. 

Color Space Conversion

In this feature, the LED video processor in your LED Control system will make sure that the images and videos of your content will show its display effect accordingly. Considering the wide color gamut of LED displays, your images, and videos will be adjusted accordingly and not limited to the small image signals of most content. 

Better Image Quality

Using an LED video processor in your LED display control system will help your display show better-quality images and videos through its image processing and enhancement technology. You can even improve and modify the quality of poor images to fit the high requirements you have for your LED display. This is made possible through advanced algorithms. 

LED Wall Splicing & Multiple Images

An LED video processor has a splicing function that enables you to manage multiple areas and screens of the entire ensemble easily and cost-effectively. The device handles multiple signals, whether similar or different, which allows the processing of multiple images all at the same time. 

LED Display

Even if you use an LED studio when capturing the content you plan to show, it will be worthless if your LED display has horrible specifications. This is why it is necessary to make sure that you’re using high-quality LED panels and cabinets. The LED displays will get the signal from the LED controllers to operate effectively. 

Once you’ve set your sights on LED screens with excellent specifications, you won’t have to worry about preparing an LED studio setup for your content. 

Hardware Needs for the LED Control System Installation

Besides all the basic elements that will make up your LED control system, there are also other components you will need for everything to function and operate effectively. Here are some of the things you will need for the hardware installation of your LED display ensemble.

  • Computer
    • Sending card or sending box (either in computer or LED video processor)
    • DVI signal cable (Two ends towards the graphic card and sending card)
    • Internet cable (RJ45 connector cable)
    • USB control cable
  • Switching power supply (220V or 110V)
  • Transmitting cables 
  • Scanning control board
  • Special video card (connected to the host controller)
  • Multifunction card (from input signals to RGB digital signals)
  • LED display framework (Depends on the type of installation: wall-mount, standing, column-type)


Understanding how the LED control system will help you optimize the function of your LED display’s operation. The basic components include a computer, LED controller, and LED screens, with an LED video processor sometimes included in the package. All the connections, tangible or not, in-between need to be accurate and effective. Make sure that when your ensemble is being set up, everything is connected properly to the right holes and places. 

You’re not required to dive deep into the technicalities that make it possible for your LED screens to work but it is highly recommended, especially if you want to maximize its use. Looking into your LED display control system will give you an inkling of the basic workings of the device and will help you think of other ways you can make use of it.
