Also referred to as the LED control card or LED display controller, LED control system is responsible to receive pictures and videos from the DVI interface or computer serial port. It displays details present in the frame memory while distinguishes LED display screens on the basis of serial display data driven partitions so as to ensure control over the timing. The system then scans pictures and videos and finally enables the screen to display them.
Based on the functionality and features, LED control systems are divided into two main categories:
Asynchronous LED Control System
Provided with single, double and full-color LED cards, this control system is capable of making its words true. Single color and double color types can only show symbols and texts while full-color LED control systems can even show videos, animation and graphics.
It is also named as offline LED card or offline control system that operates on the memory storage function. It is ideal for graphics or animations, symbols, text or video effects. Its main job is to display information with the help of a serial port or cables, which always has LED display frame memory to ensure quick and easy play. Users can also use its flash memory feature to save programs and sync them with the LED card so that the flash memory can display the respective program automatically.
Features
Asynchronous LED control system is inexpensive, simple and multi-purpose
Its sub-regional control is responsible to display content on the LED screen
This type of control system can only be used for special characters, digital clock and text
It can support tables, animations, countdowns, analog clock and pictures
It can do humidity control, temperature control, timer switch and the likes
Synchronous LED Control System
Designed to display graphics, notifications and videos in real-time, synchronous control system is a perfect choice for indoor as well as outdoor use. The major job of this control system is to manage synchronization of the LED display screen so that it can work at 60 frames per second rate along with dots to dots mapping on the computer monitor. Users are rest assured of getting a multi-gradation color display with amazing multimedia advertising effect. The worth mentioning fact is that its sync LED control card works with the controlling PC, instead of working separately.
Features
Expressive, good effects in real-time
Complicated to operate and expensive as well
Controller includes DVI Graphic card, LED sending card and LED receiving card
Comparison of Top 3 Manufacturers of LED Control System
Novastar LED Control System

colorlight led
Next in the list is ColorLight company that is dedicated to developing and marketing high quality LED control systems. The company has an independent and complete intellectual property rights for a number of technologies, which makes them one of the trusted service providers in the industry. ColorLight is responsible to facilitate LED card engineering as well as the manufacturers of LED display screens.
The company has introduced A8 dual-mode intelligent switching systems, T9 Gigabit NIC, 5A arbitrary module system, LED sending card and heavy duty products in the Q-series. An interesting fact about ColorLigh LED control systems is that they have three major products, namely:
Linsn LED Control System
Equipped with full-color light decoration, double-color and full-color synchronism, and double-color and full-color synchronism, the control system has been serving a number of LED factories in China. Referred to as the full-color LED controller, it has the following LED cards:
LED Sending Card: It is installed in the computer who controls and is connected with the DVI graphics card to send signals to the displays screen. As for laptops, LED sending boxes can be used instead of the LED sending cards.
LED receiving Card: It is installed in the LED display cabinet, where it receives signals from the sending card and transfers to the LED display modules with the help of a hub card.
Users are also satisfied with its matching software i.e. LED studio as it is available in various languages- English, Chinese and French while manufacturers are working to introduce it in Russian and Japanese as well.
