With the deepening of the application of full color LED display screen systems and the continuous development of LED display technology, users have put forward varying degrees of requirements for display effects, display content, display methods, and operating environment. They also have high requirements for system security, fault tolerance, stability, and cost-effectiveness.
The full color LED display screen control system is the core component of the LED display screen, mainly responsible for receiving image and video display information from the computer serial port or DVI interface, placing it in the frame memory, and generating serial display data and scanning control timing that can be recognized by the LED display screen in a partition driven manner.
This system can support various types of monochrome, dual color, and full color LED display screens, supporting multiple regions, multiple display objects, various special effects, and border effect display. It also supports multiple innovative functions such as Windows’s TureType font library, hardware intelligent settings, and real-time monitoring of the display screen.
The full color LED display screen control system is divided into two categories:
Asynchronous led control system
The LED display screen asynchronous control system, also known as the LED display screen offline control system or offline card, supports communication functions such as 3G and GPRS, as well as serial network ports. This system effectively solves the technical weaknesses of the synchronous system that cannot be managed in a cluster or remotely through asynchronous technology; Solved the development confusion of the advertising LED display screen industry in the past few years.
A simple LED display asynchronous control system can only display digital clocks, text, and special characters.
The asynchronous control system of graphic and text LED display screens can control the display of screen content in different regions, support analog clock display, countdown, image, table, and animation display, and have functions such as timed on/off, temperature control, and humidity control.
The system has the advantages of simple operation, low price, and a wide range of applications, widely used in outdoor advertising, traffic guidance, supermarkets, banks, beauty salons, hospitals, and other fields!
Synchronous control system
It mainly works by connecting a computer with an LED display screen, relying on the computer to store data and then sending it to the control card in the screen through a sending card. It cannot be done without the computer;
This system is mainly used for real-time display of videos, graphics, notifications, etc. Its main characteristics are real-time, rich expressive power, complex operation, and high price.
Control card type
There are many types of LED display screen control cards, which can be mainly divided into two categories: synchronous control cards and asynchronous control cards! LED asynchronous control cards can be divided into: 3G control cards (Type A), full color card series (Type M), graphic card series (Type M), and engineering card series (Type G).
A-card:
(Mainly used for 3G/GPRS communication, and can also support USB drive, network port, and serial port communication functions)
1. The best control scheme for outdoor LED display screens, supporting outdoor full color screens, wireless control, group screen control, and remote control.
2. Fast transmission speed, 10-20 times faster than GPRS
3. Through internet operation, there is no distance limit, no distance limit, and it is easy to control LED display screens in different places
4. It supports 3G, GPRS, and the internet, and can be combined with wired and wireless networking.
5. 3G systems use servers to solve cross network issues and overcome interconnection issues with various access methods
6. Not limited by operator restrictions, wireless access methods
7. Display functions: text, images, animations, EXCEL tables, time, temperature, etc.
8. Can be used for traffic information guidance, advertising, in car display, store signage, etc.
