Advantages of Selecting Kystar Receiving Cards
Rock-Solid Reliability
The KRx and Hxs LED receiving card series are built for mission-critical displays and offer a dependable base for your LED display control system. They include loop backup and firmware protection to keep signals running smoothly. The KRx series allows for quick repairs without any downtime. For environments where failure is not an option, the Hxs series offers extra features like dual power and card backups, along with advanced EMC.Future-Proof Scalability
Keep your hardware investment safe with high load capacities and support for up to 32 parallel data groups in both LED receiving card series. The KRx and Hxs series cards work well with the latest driver ICs and higher-density pixel pitches. You can upgrade firmware online, so your LED screen receiver cards stay useful during future expansions. This helps cut down on downtime and replacement costs.Precise Color Control
Address mixed-batch module discrepancies with independent RGB adjustment and dedicated Gamma control. Engineers can fine-tune red, green, and blue curves non-linearly while maintaining grayscale depth. This ensures uniform white balance and accurate color reproduction across your entire LED screen control system, even at low brightness levels.Exceptional Image Quality
Enhance your display’s visual performance with Kystar’s proprietary image enhancement algorithms. Both series support pixel-by-pixel brightness and chroma calibration. The Hxs series receiving cards offer up to 22-bit Xbits processing, full-grayscale calibration to eliminate color banding, and native HDR10/HLG support, delivering deep contrast and clarity for studios and commercial spaces.Creative Flexibility
Kystar systems support seamless, arbitrary-angle rotation, accommodating curved, irregular, and complex spatial LED configurations. Each receiving card has a built-in 3D display feature that works at half the usual load capacity. This allows for immersive visual effects and XR stage use without the need for extra 3D processors.Intelligent Maintenance
Kystar receiving cards include fast seam correction to remove visible lines between cabinets and module batch calibration for consistent visual performance across mixed-batch screens. The system provides comprehensive diagnostics such as network communication monitoring, parameter readback, and data encryption. The Hxs series also offers precise voltage and external module monitoring, giving integrators better insight into system health and reducing maintenance needs.Which LED Receiving Card Is Right For You?

Kystar LED Receiving Card FAQ
1. How do I know if the receiving card is compatible with my specific LED modules?
Kystar receiving cards are adaptable and natively support a wide range of mainstream and advanced PWM driver ICs. Supporting up to 32 parallel data groups, both the KRx and Hxs series accommodate various pixel pitches, ensuring seamless integration with your LED modules.
2. What happens to the LED screen if a network cable fails during operation?
To ensure uninterrupted performance, every Kystar LED receiving card has built-in Loop Backup technology. If a primary network cable disconnects or fails, the signal instantly switches to the backup loop without visible flicker or blackout. For mission-critical setups, the Hxs series also supports dual-card and dual-power backups.
3. Can the receiving card fix the visible bright and dark lines between LED cabinets?
Yes. Mechanical misalignment often causes bright or dark lines between cabinets. Kystar LED screen receiver cards feature proprietary Fast Seam Correction and module batch calibration algorithms. Engineers can quickly fine-tune edge pixel brightness via software, eliminating visible seams and delivering a uniform visual canvas.
4. Do I need to power down the entire LED wall to replace a faulty receiving card?
It depends on the series. While standard maintenance often requires powering down, the Kystar KRx series (Gold Cards) is engineered to support maintenance without shutdown. This hot-swappable design lets technicians replace a faulty card on the fly, enabling rapid on-site troubleshooting and reducing downtime during live events.
5. Why should I choose a 22-bit+ processing card (Hxs series) over a standard 18-bit card?
While 18-bit processing works well for general commercial displays, low-brightness environments often reveal color banding and detail loss. The Hxs premium LED display receiving card uses up to 22-bit+ Xbits processing and full-grayscale calibration. This preserves deep color depth and contrast even at very low brightness, making it the industry standard for XR studios, TV broadcasts, and high-end indoor installations.
