Control system connection diagram
The control systems of LED displays are mainly divided into synchronous control and asynchronous control. They each have unique characteristics and application scenarios
1, The synchronous control system is a control method that synchronizes the LED display screen with the computer monitor.
Features:
a, Real-time: The synchronous control system can map the image on the computer monitor in real time at an update rate of at least 60 frames per second, meeting the application scenarios with high real-time requirements.
b, Rich expression: Due to synchronous control, the display screen can display multiple grayscale colors to achieve multimedia advertising effects.
c, Complex operation: The operation of the synchronous control system is relatively complex and requires professional technicians to set up and maintain.
d, High price: Due to high technical requirements, the cost of the synchronous control system is relatively high.
e, Dependent on the computer: The content of the display screen is completely synchronized with the computer monitor. Once the computer is turned off, the display screen will also stop displaying.
f, Application scenario: The synchronous control system is mainly suitable for places where dynamic video or graphic information needs to be displayed in real time, such as TV stations, large-scale event sites, shopping malls, etc.
2, Asynchronous control system, also known as offline control system or offline card, is mainly used to display text, symbols, graphics or animation.
Features:
a, Simple operation: The operation of the asynchronous control system is relatively simple, and users can easily edit and update the display content.
b, Low price: Due to the low technical requirements, the cost of the asynchronous control system is relatively low.
c, Wide range of use: The asynchronous control system is suitable for a variety of application scenarios, including outdoor advertising screens, information release screens, etc.
d, Regional control: It can realize the control of the display screen content in different regions, with high flexibility.
e, Independent playback: Even if the computer is turned off, the LED display can be displayed independently, but the playback content is limited by the storage capacity of the control card.
f, Application scenario: Suitable for places with low real-time requirements, such as bus stops, shopping mall signs, window displays, etc.
