  The control system of the full color LED advertising screen is mainly divided into synchronous control and asynchronous control,both in the control mode,content update,description and use of stability there will be some differences,today follow China Ddon Visual to see,synchronous control system and asynchronous control system of the difference between what are the main performance?

  A、Synchronous Control System:

  1、Real-Time Display:

  Synchronous control provides real-time display of content on the LED screen.It's suitable for applications where immediate updates are required,such as live events,sports broadcasts,and real-time information display.

  2、Complex Content:

  Synchronous control systems can handle complex multimedia content,including videos,animations,and live feeds.They offer high refresh rates and smooth motion,making them ideal for dynamic content.

  3、High Refresh Rates:

  Synchronous control systems can achieve high refresh rates,which means smoother motion and reduced flickering when displaying videos or animations.

  4、Control Complexity:

  Synchronous systems can be more complex to set up and manage,as they require a constant and stable connection to the content source.They may involve more technical equipment and configurations.

  5、Continuous Data Transmission:

  Content is transmitted to the LED screen in real-time or near-real-time,ensuring that the displayed information is always up to date.

  6、Usage Scenarios:

  Synchronous control is commonly used in scenarios where real-time updates and dynamic content are crucial,such as sports stadiums,concert venues,and live news broadcasts.

  B、Asynchronous Control System:

  1、Content Scheduling:

  Asynchronous control allows you to schedule content to be displayed on the LED screen at specific times.Content is preloaded onto the screen's internal memory,allowing the screen to operate independently of a constant data connection.

  2、Simple Content:

  Asynchronous control systems are better suited for static or simple content,such as images,text messages,and basic animations.

  3、Lower Refresh Rates:

  Asynchronous control systems typically have lower refresh rates compared to synchronous systems.This makes them less suitable for displaying fast-moving or high-motion content.

  4、Lower Technical Complexity:

  Asynchronous systems are generally simpler to set up and operate.They don't require a constant connection to a content source and are suitable for applications where immediate updates are not necessary.

  5、Offline Operation:

  Once content is loaded onto the LED screen's internal memory,the screen can operate independently without the need for continuous data transmission.

  6、Usage Scenarios:

  Asynchronous control is often used for applications where content can be preloaded and scheduled in advance,such as retail displays,transportation information boards,and outdoor advertising screens.

  To sum up,the synchronous control system is more suitable for real-time changes in the display of content,such as some concerts,sports events,financial securities industry,etc.,while the asynchronous control system is more suitable for pre-set and regularly updated advertising content,such as building exterior wall advertising,public interest display advertising,shopping mall promotional advertising,etc.,when the user chooses the control system mode,This method must be based on the actual usage requirements of the application scenario.The above is about synchronous control system and asynchronous control system difference analysis,I hope this article can help you.China Ddon Visual focuses on the development,production and sales of high-quality full-color LED display,providing full-color LED display module,LED stage rental screen,LED advertising screen spot wholesale and on-site construction,supporting the customization and development services of shaped LED display,if you need assistance with related projects,welcome to call Ddon.We will provide you with a full range of product solutions and quality service.
