LED display control system is the core component of the LED display, and its main function is to accept the picture and video information from the computer serial port or DVI interface, into the frame memory to display images. It is mainly synchronous and asynchronous control system control system in which asynchronous control system, also known as off-line or off-line card control system, and its main function is to display a variety of graphics, animation, text or symbols. So now, asynchronous control system development like?
Currently asynchronous control card from the scale, and the synchronization control card can not be compared, but asynchronous control card has its own characteristics, such as the relatively wide range of applications. Synchronization control card itself subject to some restrictions, there is a need to control the engine room, which it can not lead to large-scale applications in many fields, such as in a lot of outdoor unattended places, synchronization control card impossible, but it can be asynchronous control card .
Asynchronous control card broader range of applications, so it is more room for development. Secondly, asynchronous control card developed up to now, more than ten years. When early, its reliability, security is more prominent a problem, but after so many years of development, asynchronous control card for many manufacturers, this is not the core of a problem.?Single-color asynchronous control system has been developed for nearly 20 years, all aspects of performance has been very mature; Asynchronous full-color control system from 2012 began to apply on the door first screen and the stage led display, is currently still in its infancy, with the embedded processing performance getting stronger, the future trend will be embedded, there may be substituted or fused with synchronous control system, the birth of a new control system.?
Currently, full-color asynchronous control system performance barely able to meet the market demand, due to the large quantities have not been used, the system more complex reasons, reliability compared to single-color asynchronous control system, full-color synchronous control system to almost.?With the led display industry continues to develop, more and more small and medium display applications to the media display, traffic guidance display, commercial chains display, the first door signs display industry. Because of its asynchronous control system can be embedded, high stability, small size, mobility and strong features by industry user's favorite, but also led to the display integrated, intelligent indispensable product, from a performance point of view, from simple text playback to 480p, 1080p video playback asynchronous system is an inevitable trend. With cluster release, mobile publishing, interactive software, asynchronous control system allows the display to become more intelligent. Because unattended display asynchronous control, so for asynchronous systems, stability is the key factor.
All in all, intelligent, powerful performance, high stability of the future asynchronous system.?In summary, we can generally understand that with the development of the LED display control system also will make new developments, although the scale of asynchronous control system is not as synchronous control system, but because of its own characteristics, stability and reliability is not the most prominent problem, embedded, intelligent and integrated or but its development trend.
