Introduction
The LED display is a new type of information display media that developed rapidly in the late 1980s all over the world. As the core component of the LED display screen, the LED control system also appeared at the same time. With the rapid development of the times, LED display screens from monochrome to full color, from simple text play, to now 4K, and 8K video play, this intermediate conversion can not be separated from the work of the control system.
As a user of LED display screens, it is essential to understand the working principle of LED control systems and how to use them. This article will take you through the control system of the LED display screen, making it more convenient for you to use.
1. What is an LED display control system?
LED control system, also known as LED display controller, or LED Display Control Card, is LED display peripheral equipment, mainly responsible for processing from PC to LED display data conversion and receiving video transmission by the PC source. It is an LED display screen that can display the core of the content components.
2.Control method of LED display screen control system
As mentioned above, the control system of LED display screens mainly controls the content played on the screen and receives and processes video sources. So where did the video source come from? Video sources are generally transmitted from computers, cameras, recording devices, etc. According to transmission methods, they can be divided into the following 2 categories:
- Synchronous play
1). What is synchronous play？
Synchronous play refers to the connection between the play device and the LED display screen through a data transmission cable. The content played is real-time, synchronized, and always connected to the video source device during use. For example, if the device of the video source is playing a certain photo, the LED display screen will also play that photo. If the video source device experiences a power outage or disconnection, the LED display screen will also display a black screen. This play style is commonly used for real-time monitoring of cities or stage performances.
- Method of synchronous play
2.1). Single video source: A single video source can only be connected to one video source, which can be a computer, camera, or recording device. It is connected to the LED control system’s receiving card through a data transmission cable and then transmitted to the LED display screen to achieve synchronization.
2.2) Multiple video sources: From the name, it can be seen that this control system can connect multiple video sources for transmission. Unlike a single video source, it needs to first transmit the transmitted video to the video processor, process it, and then transmit it to the receiving card and finally to the LED display screen.
- Asynchronous play
1). What is asynchronous play
Asynchronous play, also known as offline play, refers to a play method that can be played asynchronously with the device of the video source, and can even directly implement loop play; For example, if you use a computer to transmit several videos to the control system of an LED display screen after the transmission is completed, you can directly exit, and the LED display screen will cycle through the content you have transmitted. This playing method is commonly used in advertising LED displays to loop through advertisements.
2). Asynchronous play method
The LED display screen that can achieve asynchronous play needs to have an SD storage card, 4G network module, or WIFI, and your PC needs to download dedicated software or have a dedicated website, all of which are necessary requirements for asynchronous play.
Because asynchronous play is transmitted by the network, there is no need to use a transmission line. If the distance is close, you can directly connect to the hotspot of the LED display screen for video transmission. If the distance is far, such as across regions or countries, log in to a dedicated website on your computer and enter your LED display screen account and password. Click on the video management center to upload and manage the video source.
3. How to choose the control system for LED display screens?
Before making a choice, you have a clear understanding of the following:
What do you buy LED displays for? Is it simply playing advertisements or what should be played in real-time?
Do you need to access multiple video sources simultaneously?
Do you have situations where you need to control the LED display screen for ultra-long distances? For example, across regions, cities, and even across borders
Think this through and you’ll know what kind of control system to buy for your LED display.
4. List of Excellent Manufacturers of LED Display Control Systems
With the development of LED display screens, many companies that produce LED display control systems have emerged, as there are many production companies, making it difficult for consumers to choose. I have listed some reliable and professional LED display control system manufacturers for your reference.
