The LED display control system is the core component of the LED display. Its main function is to accept the picture and video information from the computer serial port or DVI interface, and put it into the frame memory to display the picture. It mainly has a synchronous control system and an asynchronous control system. The asynchronous control system is also called an offline control system or an offline card, and its function is mainly to display various graphics, animations, characters or symbols. So now, what is the development of asynchronous control systems? At present, the asynchronous control card cannot be compared with the synchronous control card in terms of scale, but the asynchronous control card has its own characteristics, such as a wider application. The synchronous control card is limited by itself and needs to be controlled by a computer room. This makes it impossible to apply in large scale in many fields. For example, in many outdoor unattended places, the synchronous control card cannot be used, but the asynchronous control card can . Asynchronous control cards have a wider range of applications, so it has more room for development. Second, asynchronous control cards have been developed for more than a decade. In the early days, its reliability and security were a prominent problem. However, after many years of development, this is not the core issue for many asynchronous control card manufacturers. The single-and-two-color asynchronous control system has been developed for nearly 20 years, and the performance of all aspects has been very mature. The full-color asynchronous control system has only been applied to the door screen and large screen since 2012. It is still in the early stage of development, with embedded processing. The performance of the device is getting stronger and stronger, and embedded will be the trend in the future. It is possible to replace or integrate with the synchronous control system to create a new control system. At present, the performance of the full-color asynchronous control system can barely meet the market demand. Because it is not used in large quantities, the system is more complicated, and the reliability is worse than that of the single-color asynchronous control system and the full-color synchronous control system. With the continuous development of the LED display industry, more and more small and medium-sized display applications have been applied to industries such as media display, traffic-induced display, commercial chain display, and door sign display. Due to its embeddability, high stability, miniaturization and high mobility, the asynchronous control system is deeply loved by users in the industry. It is also an indispensable product for LED display to be integrated and intelligent. From the perspective of performance, Simple text playback to 480p, 1080p video playback is an inevitable trend of asynchronous systems. With cluster publishing, mobile publishing, and interactive software, the asynchronous control system makes the display smarter. Since the asynchronously controlled display is unattended, stability is a critical factor for asynchronous systems. All in all, intelligence, high performance, and high stability are the future of asynchronous systems. In summary, we can roughly understand that with the development of LED display, the control system will also make new changes and developments. Although the scale of the asynchronous control system is not as good as that of the synchronous control system, due to its own characteristics, stability. And reliability is not the most prominent issue, embedded, intelligent and integrated or its development trend.
