LED control cards typically have two interface types: 08 and 12. Both interfaces are suitable for single and dual-color LED displays. Specifically, the 08 interface is configured with two sets of red and green signals, while the 12 interface is equipped with only one set of red and green signals. In addition, these interfaces share some key control signals, such as OE (Enable), NC (Always), DR (Data Input), CLK (Clock), STB (Storage), and SC (Scan). These signals play a crucial role in LED control.
The OE signal controls the LED display's on/off state. When the OE signal is high, the LED display functions normally; conversely, when the OE signal is low, the LED display is disabled. The NC signal indicates that the control card is always active, ensuring the stability of the LED display. The DR signal, as a data input signal, is used to transmit data to the LED control card, enabling it to process and display correct information. The CLK signal is the clock signal, used to synchronize data input and output, ensuring the accuracy of data transmission. The STB signal is the storage signal, used to indicate that data is ready to be stored and processed. The SC signal represents the scan signal, used to control different areas of the LED display screen, enabling row-by-row or column-by-column scanning display.
