What is LED display control system?

An LED display control system is a comprehensive setup that manages and showcases videos, animations, images, and textes on an LED screen. Comprising both hardware and software components, this system is integral to the functionality of an LED screen, acting as its "brain." Without this system, the LED screen would be incapable of displaying any content.

Types of LED Display Control Systems

LED display control systems are broadly categorized into two types: Synchronous Control and Asynchronous Control.

Synchronous Control

In a synchronous control system, the content displayed on the LED screen is synchronized in real-time with the content shown on the control computer's monitor or other input devices. This means the LED screen acts as a live mirror of the control computer, displaying exactly what is being shown on the computer screen at the same time.

Asynchronous Control

An asynchronous control system, in contrast, allows content to be pre-loaded onto the LED screen's control card using devices such as computers, laptops, mobile phones, tablets, SD cards, or USB drives. Once the control card (equipped with memory storage) receives and stores the content, it autonomously displays the pre-programmed material in a specified sequence, style, and duration, looping through the content as configured.

5 Differences between Synchronous Control and Asynchronous Control.

1. Storage Memory in Hardware

Asynchronous Control:

• Features built-in storage memory in the control hardware.
• Can store multiple content files and operate independently without needing a constant connection to a computer or laptop.

Synchronous Control:

• Lacks built-in storage memory.
• Requires a continuous connection to a computer or laptop during operation.

2. Operation and Connectivity

Asynchronous Control:

• Does not require a computer or laptop to function after content is uploaded.
• Content can be modified or updated using a computer, laptop, tablet, or mobile phone when needed.

Synchronous Control:

• Must remain connected to a computer or laptop while operating.
• Requires real-time control and management for content playback.

3. Display Modes

Asynchronous Control:

• Offers limited display modes, such as pop-up, slide-screen, roll-up, and roll-down.

Synchronous Control:

• Provides a wide variety of display modes, especially when used with professional software and video processors.
• Enables nearly unlimited creative possibilities for content display.

4. Ease of Operation

Asynchronous Control:

• Simple and user-friendly.
• Once content is sent, the system runs automatically without manual intervention.

Synchronous Control:

• More complex to operate.
• Requires someone to manage and control the content playback in real-time.

5. Cost and Capabilities

Asynchronous Control:

• Generally more cost-effective.
• Suitable for smaller-scale or simpler applications.

Synchronous Control:

• Typically more expensive.
• Capable of controlling a larger number of pixels, making it ideal for advanced and large-scale applications.

How to control LED screen?

We will supply software and instructions for both asynchronous control and synchronous control. Please contact us now. Here are some brief instructions.

Synchronous Control

• First of all, power on, then connect all the cables with screen and computer/laptop.
• Second, please press "WIN" button and "P" button on your keyboard at same time, then choose "duplicate".
• Third, open software to control the screen.
• More details, please check instructions.

Asynchronous Control

• First of all, power on the screen and computer/laptop.
• Second, open software to create contents (videos, pictures, text etc.).
• Third, upload contents to screen.
• More details, please check instructions.

Which one is better?

Typically, we recommend synchronous control for indoor applications and asynchronous control for outdoor applications. However, for event-based applications—whether indoor or outdoor—we generally recommend synchronous control.

Applications for Synchronous Control LED Screens

Synchronous control systems are ideal for scenarios where content needs to be updated in real-time. Common applications include:

Indoor LED screens:

• Meeting rooms, conference rooms, churches, hospitals, offices, cinemas, etc.

Indoor and outdoor rental LED screens:

• Exhibitions, stages, performances, concerts, etc.

Public spaces:

• Airports, train stations, restaurants, etc.

In these settings, content such as videos, images, and text often requires frequent or real-time updates, making synchronous control the preferred choice.

Applications for Asynchronous Control LED Screens

Asynchronous control systems are better suited for scenarios where content does not need to be changed frequently. Common applications include:

Outdoor LED screens:

• Pole or column billboards, building walls, shopping malls, plazas, natural parks, etc.

In these cases, content such as advertisements, images, and text is usually pre-loaded and displayed on a loop, making asynchronous control a cost-effective and efficient solution.
