LED display control cards are divided into two types: transmitting cards and receiving cards. Each card performs a specific function within the system, working together to ensure the normal operation of the display.
The primary responsibility of the transmitting card is to transmit signals from the video processor to the LED display. It encodes the processed video signal into a format that the display can receive and then transmits these signals to the receiving card via data cables. Therefore, the transmitting card acts as a "bridge" for signal transmission in the LED display system.
The receiving card is responsible for receiving signals from the transmitting card and decoding them for display on the LED display. It converts the received signal into a format that the display can understand and displays it on the corresponding pixels. Therefore, the receiving card ensures effective signal transmission and correct display.
In some modern systems, the functions of the transmitting and receiving cards may be integrated into a single system card. This integrated design simplifies the system configuration and installation process, eliminating the need for users to install a separate transmitting card in the video processor. This two-in-one system card still possesses the functions of sending and receiving signals, providing a more efficient and convenient solution.
In summary, LED display control cards include transmitting cards and receiving cards. The transmitting card is responsible for signal transmission, while the receiving card is responsible for signal reception and display. In some cases, the emergence of system cards simplifies the configuration and use of LED display systems. By understanding the composition and function of LED display control cards, users can better select equipment that suits their needs and ensure the normal operation of the display.
