LED receiving card is another important component in LED display systems. It is a device used to receive data signals sent by the LED sending card and control the display of the LED display screen. The receiving card is responsible for converting the received data signal into a format that is compatible with the LED display screen, and then transmitting the converted signal to the display screen through a data cable. LED receiving cards are available in various specifications and can support different display resolutions and refresh rates. They play a crucial role in ensuring the synchronization and stability of LED display screens.
