At present, asynchronous control card from the scale, and synchronous control card can not be compared, but the asynchronous control card has its own characteristics, such as the application of a wide range. Synchronous control card by their own some restrictions, need to have a room to control, which led to it in many areas can not be large-scale application, such as in many outdoor unattended places, synchronization control card can not, but the asynchronous control card can The Asynchronous control card applications a wider range, so it's more room for development. Second, the asynchronous control card development so far, has been more than a decade. In the early days, its reliability, security is a more prominent problem, but after so many years of development, for many asynchronous control card manufacturers, this is not the core of a problem.
With the continuous development of the LED display industry, more and more small and medium-sized display applications to the media display, traffic-induced display, commercial chain display, the first door signs display and other industries. Asynchronous control system because of its embeddable, high stability, miniaturization, mobility and strong characteristics of the industry by the user's favorite, but also led display to integrated, intelligent indispensable products, from the performance point of view, from the performance point of view Simple text playback to 480p, 1080p video playback is an inevitable trend of asynchronous systems. With the cluster release, mobile publishing, interactive software, asynchronous control system to make the display more intelligent. As the asynchronous control of the display unattended, so for asynchronous systems, stability is a key factor. All in all, intelligent, powerful, and high stability is the future of asynchronous systems.
