With the continuous progress and development of society, led display has made great progress in control technology. The development of grayscale control technology, the display of true color images, the flexibility and high efficiency of the drive circuit, and the improvement of control system technology all reflect the rapid development of LED industry technology.

Moreover, the current information technology is also constantly developing. In the information display system composed of multimedia and various display devices, the LED display adopts intelligent network control, and the network control multi-screen technology has also been widely used. And people also have high requirements on the quality of LED display screens. While obtaining information, they also have higher requirements for information acquisition methods and information quality.

Ordinary information display methods are gradually being replaced by LED displays, and some have even been eliminated. Then how we develop a flexible and efficient control system is a very meaningful research topic. This requires starting from the actual engineering and working hard on the design of the LED display to develop an efficient control system software, from information editing, extraction, Research on display and control, and develop a general control system, which provides a good foundation for the application of led display. The led display control system mainly realizes the initialization, display and control functions of the led advertising screen information through the graphic controller, which is specifically explained from the aspect of target design.

1. Support the initialization setting and video wall price loading of display parameter software;

2. Support Chinese and English clock editing and display;

3. Support roaming subtitle editing and display;

4. Support multi-region screen editing and display;

5. Support screen display special effects;

6. Support software automatic switch;

Seven, support temperature, humidity and other sensor information editing and display;

8. Powerful hypertext editor (RTF format);

9. Support editing, browsing and playing of picture information;

10. The display mode, running speed and dwell time of each page can be adjusted by software;

11. Preview and send display information;

The above eleven points show that in order to achieve flexible and efficient control system development for led display, we must start from the target design, so as to realize the rapid development of led display in society!
