In LED display system, receiving card and sending card are indispensable components. They work together to ensure that LED displays accurately and efficiently display various information. This article will provide a detailed introduction to the working principles of the LED display screen receiving card and the sending card, as well as the coordination between the two.
The LED display screen receiving card is mainly responsible for receiving data signals from the sending card, and decoding, brightness adjustment, and other processing of these signals. The following is its specific workflow:
Receiving signal: The receiving card receives data signals from the sending card through specific interfaces (such as USB, Ethernet port, etc.).
Decoding signal: The receiving card decodes the received signal and converts the digital signal into an LED light on/off control command.
Brightness adjustment: The receiving card can adjust the brightness of the LED lights as needed to achieve the best display effect.
Output control signal: The receiving card outputs the processed control signal to the LED display screen, controlling the on/off status of the LED lights.
The main function of the LED display screen sending card is to convert images, text, and other information from computers or other devices into digital signals required by the LED display screen, and transmit them to the receiving card through specific interfaces. The following is its specific workflow:
Input information: The sending card receives information from a computer or other device, such as images, text, etc.
Signal conversion: The sending card converts this information into the digital signal required for the LED display screen.
Transmission signal: Send a card through a specific interface to transmit digital signals to the receiving card.
The combination of LED display screen receiving card and sending card is mainly reflected in the following aspects:
Interface matching: The receiving card and the sending card need to be connected through the same interface, such as a USB interface or network port. Ensuring consistent interface types is the foundation of their collaborative work.
Data transmission protocol: The same data transmission protocol must be followed between the sending card and the receiving card to ensure accurate data transmission. Common protocols include DMX512, RS232, etc.
Display content synchronization: The sending and receiving cards need to maintain display content synchronization. This usually requires setting and adjusting at the software level to ensure consistent data transmission latency and display effects between the sending and receiving cards.
Brightness and color adjustment: The receiving card can adjust the brightness of the LED lights as needed to achieve the best display effect. At the same time, the sending card can also adjust the display color to meet the needs of different scenes.
Troubleshooting and maintenance: When the LED display system malfunctions, it is necessary to check the working status of both the sending and receiving cards simultaneously. Confirm whether the connection between the two is normal and whether data transmission is smooth. In addition, regular maintenance and upgrades of the system are also essential to ensure its stability and reliability.
the combination of the LED display receiving card and the sending card is crucial to ensure the normal operation of the entire LED display system. Understanding and mastering their working principles and usage methods can help to better leverage the performance advantages of LED displays and provide efficient and high-quality visual display services for various application scenarios.
