Differnt LED display control systems

What is LED display control system?

LED display control system is a system that controls and displays videos, animations, pictures, texts etc. on LED screen. It includes hardware and software. It plays a very important role in LED screen. It looks like the brain of LED screen. Without this system, you can’t display anything on the LED screen.

There are 2 kinds of LED display control systems, Synchronous Control and Asynchronous Control.

Synchronous Control

Synchronization system means that the displaying content of the LED screen can display the content on the control computer monitor/DV in real time and synchronously. The LED screen is synchronize with the control computer, what the computer monitor displays is what the LED screen displays.

Asynchronous Control

Asynchronous display means send the edited contents in advance to the control card of the LED screen through computer, laptop, mobile phone, Tablet, SD card, USB flash drive, etc. After the control card (with memory storage) accepts the contents, it will display the edited contents in order, displaying mode, dwell time then display in a loop.

Differences between Synchronous Control and Asynchronous Control.

The main difference is: With or without storage memory in hardware.

The asynchronous control system does not need to be connected to a computer or laptop while working. The built-in storage memory in control hardware can store multiple contents and can run independently. When you need to modify the contents inside control system, you can modify it through your computer, laptop, tablet or mobile phone.

But synchronous control requires a computer or laptop while it is working because it doesn’t have storage memory.

Asynchronous control LED screens have fewer display modes. There are pop-up, slide-screen, roll-up, and roll-down display modes, etc.

But synchronous control LED screens have a variety of display modes (if you use professional software and video processor to produce and play programs, there are unlimited display modes).

Asynchronous control LED screens are easy to operate. You only need to send the contents. Then the screen will auto run. But synchronous control LED screens require someone to operate.

Generally, the price of synchronous control system is more expensive than asynchronous control system, and it can control more pixels.

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?

Normally we recommend synchronous control for indoor applications, and asynchronous control for outdoor applications. But we will recommend synchronous control for events application no matter indoor or outdoor.

Here are some installation applications for synchronous control LED screen. Most indoor LED screen, indoor and outdoor rental LED screen. Such as meeting room, conference room, church, hospital, Station, Airport, Restaurant, Office, Cinema, Exhibitions, Stage, Performance, etc. The contents such as videos, pictures, text, etc. need to be updated in real time, using synchronous control system.

Here are some installation applications for asynchronous control LED screen. Most outdoor LED screen. Such as Pole or Column Billboard, Shopping Mall, Plaza, Natural Park, Building Wall, etc. Contents such as advertising videos, pictures, text, etc. do not need to change frequently, using asynchronous control system.
