LED Display Receiving Card
A receiving card distributes signal data correctly to LED modules for stable mapping and clean screen output.
A receiving card is one of the most important control components inside an LED display cabinet, because it takes signal data from the sender or video processor and distributes that data accurately to the LED modules, driver ICs, and scanning lines. In simple terms, it helps the screen show the right content in the right position, with proper mapping, brightness behavior, and stable image output. Different receiving card models can vary in HUB port type, loading capacity, supported scan modes, grayscale performance, refresh-related capability, and compatibility with specific cabinet or module configurations. That is why choosing the correct receiving card is essential for smooth display performance, clean visuals, easier configuration, and long-term system reliability.

FAQ
Quick answers about receiving card compatibility, HUB interface planning and cabinet mapping support.
Match the receiving card with your controller ecosystem (NovaStar/Huidu/Colorlight), HUB connector type, scan mode, cabinet resolution, and module wiring. Sharing cabinet photos and module details helps ensure correct compatibility.
HUB75 is a common LED module interface standard. Your receiving card, HUB board, and ribbon cable must match the module interface to avoid mapping issues, missing rows, or unstable output.
Yes. Flicker or lines can come from wrong mapping, incompatible scan settings, unstable power, loose ribbon cables, or a receiving card that does not match the module drive requirement. Proper configuration and cabling checks are essential.
Sometimes. If the new module uses different scan mode, pinout, or loading capacity, you may need a compatible receiving card and matching HUB board to keep the cabinet stable and service-friendly.
Yes. We can guide mapping, configuration, and troubleshooting based on controller model, cabinet layout, and photos/videos from the site to speed up commissioning.
Send module front/back photos, HUB connector close-up, pixel pitch and scan rate, cabinet resolution (W x H), and your controller brand/model to confirm compatibility quickly.
