LED screens have established an incredible reputation in the market as one of the best and most advanced marketing tools offered today. People are more inclined to look at images and videos for marketing since the content is more instant and easier to digest. In fact, according to a study, over 59% of people are more inclined to be interested in a brand or product displayed on a screen. 

With LED screens becoming increasingly popular, it is understandable that you would want to take this opportunity and use it to your advantage too. From how to build LED screen to their maintenance, it’s understandable that you would want to learn more about this device. 

There are /many things to learn about when dealing with this device but it’s important to know the basics. And if you want to save some cash and control your LED screen better, building it might be a good option. Of course, you need to learn first how to build LED screen. And depending on the type of display you’re thinking of building, you also need a crash course on how to make flexible LED screen and how to make an RGB LED screen. 

Basic Steps How To Build LED Screen

LED display refers to a visual device powered by light-emitting diodes. They are then arranged in a way that can produce images just with the LED’s illumination. While the technology seems complex, you can build your LED screen. It’s possible if you know how to make LED display board at home. This way, you can save so much and escape from paying charges from manufacturers and vendors. 

To help you create your masterpiece, here is a simple step-by-step guide on how to build LED screen. 

Step 1: Gather The Materials You Will Need

The first step when building your LED screen is gathering all the components that you will need in the project. The materials can vary depending on your budget, requirements, and preferences. Just to give you a look at the basic items you need to look into, here are some that you will need. 

  • LEDs: LED lamp beads are light-emitting diodes, which form LED modules with PCBs, plastic kits, PCBs, etc.

  • LED display modules
  • Power Supply
  • Control System
    • Controller 
    • Sending card 
    • Receiving card
  • Cabling
    • Data cable 
    • Power cable
  • Cabinet or chosen mounting hardware
    • Mounting bracket 
    • Finished cabinet frame
  • Building Tools
    • Screwdriver
    • Multi-meter

Before you go out and complete this first step on how to build LED screen, make sure that you decide on the specifics of the components. These are some of the aspects you need to work on first:

  1. LED modules – Choose the module that will be ideal for your needs and consider the size, resolution, brightness, and pixel pitch you require for your LED screen. 
  2. Power supply – Search for a power supply with small and simple to look at. You can choose either UL- or CE-approved.
  3. Control system – For the controller box, your chosen pixel pitch will be taken into account. Look into the cards, especially since there’s a maximum loading LED quantity they can power. The quantity of your cards depends on the card’s loading capacity and the pixel density of your LED display. 
  4. Cables – You will need both data and power cables to make sure you have enough meters of these cables. 
  5. Cabinets – If you choose to use a cabinet for your LED screen, you can either go for the standard iron sheet built into a simple cabinet or an aluminum cabinet. 

When understanding how to build LED screen, make sure that you have a basic understanding of how the different components function and how they contribute to the operation of the LED screen. 

Step 2: Connect All Parts

The second step in this guide on how to build LED screen is to connect all the necessary parts. Start with the LED modules and properly connect them to the controller since it is responsible for what is shown on the screen. Check the cabling that connects both components, as well as the cabling that connects them to the power supply. Look into the cables and check out if you’re using the data cable or power cable.

Step 3: Mount The LED Screen

After everything is connected, the next step of how to build LED screen is to position the LED screen. You can mount them on the wall or use a cabinet to protect your LED screen from possible elements that can damage it. Your mount or cabinet choice can depend on the following factors:

  • Screen size and weight 
  • Indoor or outdoor application
  • Budget 
  • Type of LED screen

Step 4: Config The LED Screen

After setting everything up, the final step in this how-to-build LED screen guide is to configure the LED screen and check if it is properly working. Connect your laptop to the LED screen after putting together everything. You can either display a test pattern or the content you’re planning to show on the LED display in the first place. Check for possible errors, including the following common issues:

  • Blank screen
  • Static lines on the screen
  • No signal detected

Practical Tips On How To Build LED Screen

If you choose to learn how to build LED screen, you have the freedom to customize it the way you think will benefit you the most. In building your custom-made LED screen, here are some practical tips worth looking into. 

1. Gather all the components in one location

Before starting to assemble the LED display, gather all components, materials, and tools you will use in one location to have a more convenient building. You can place them in an assembly line to make it more accessible. Preparing beforehand can help you save time and at the same time be more efficient in your build. 

2. Choose the right type of LED module

While you can also learn how to make LED display board circuit, there are LED modules readily available that you can use. Indoor LED modules are different from outdoor LED modules so take that into account when choosing the right type of LED module. The former has a regular brightness while the latter needs to have high brightness to operate under direct sunlight. 

Another factor to consider when choosing an LED module is the size of your LED display. This will tell how many LED modules you will need for your project. 

3. Make sure to order spare parts

Another practical tip to follow when learning how to build LED screen is to always order spare parts. While you don’t want to hope that the items you ordered have been damaged, you don’t know what may happen so it’s best to be safe. Some of the LED panel modules may have issues or some cables are not working. 


If you want to learn how to build LED screen, start with the basics. Be familiar with the step-by-step guide that goes with creating an LED display. Make sure to apply some practical tips that can help you be more economical and efficient when doing this project. Bear in mind though that you don’t have to force yourself to create one if you don’t want to deal with all the technical aspects that come with it. You can also ask for the help of experts and purchase a ready-made LED display to avoid wasting time.
