Frequently Asked Questions

PIF-S modules use standard flexible SMD technology and are a practical choice for general curved indoor displays where mature performance, flexible configuration, and project cost are important. PIF-G modules combine flexible SMD LEDs with a GOB protective surface layer, providing improved resistance to accidental contact, dust, static exposure, and routine handling.

PIF-C modules use flexible COB technology and are designed for fine-pitch and ultra-fine-pitch applications requiring higher pixel density, strong contrast, close-viewing detail, and premium visual performance. The appropriate platform should be selected according to pixel pitch, viewing distance, protection requirements, curvature, supporting structure, and project budget.

The PIF Series currently covers pixel pitches from P0.9375 to P4. Available module formats include 240×120mm, 256×128mm, 320×160mm, and 300×168.75mm.

Smaller pixel pitches provide higher pixel density and finer image detail for close-viewing applications, while larger pixel pitches provide practical coverage and better cost efficiency for larger indoor displays. Module size should be selected according to the screen dimensions, required native resolution, curvature, supporting structure, installation layout, and maintenance method rather than pixel pitch alone.

Yes. PIF Series modules can be used for compatible concave, convex, cylindrical, wave-shaped, ribbon-style, and other custom indoor LED structures.

However, the allowable bending direction, bending angle, and minimum installation diameter vary by module model, pixel pitch, PCB design, and rear housing. Flexible modules must be installed on an accurately engineered support structure with suitable curvature, flatness, magnetic attachment, load capacity, ventilation, grounding, cable routing, and maintenance access. Confirm the model-specific curvature requirements before designing or manufacturing the structure.

Matching the module size and pixel pitch does not guarantee direct compatibility with an existing flexible LED display. Before replacement, expansion, or mixed installation, confirm the mounting structure, magnet layout, bending direction, signal interface and pinout, scan rate, driver IC, DC power connector and polarity, receiving-card configuration, firmware, and calibration data.

Modules from different manufacturers, product models, technology platforms, or production batches should not be mixed unless their mechanical, electrical, signal, control, and calibration compatibility has been verified. For consistent brightness and color performance, modules installed within the same screen should use the same product configuration and production batch whenever possible.

Most PIF Series modules use magnetic mounting and can support front-access installation and maintenance on compatible engineered structures. This can simplify module positioning, removal, replacement, and maintenance in curved installations or locations with limited rear access.

However, magnetic mounting does not mean that the modules can be installed without structural support. The actual installation and maintenance method depends on the module model, magnet layout, supporting frame, cable routing, removal clearance, and overall display design. Confirm the complete mechanical and electrical structure before installation.

Yes, POF Series modules are designed for outdoor LED display projects, but the protection configuration varies by model. POF-S models use an all-in-one silicone flexible structure with the module-level protection stated on each product page. POF-SR models provide IP65-rated front protection and IP54-rated rear-cover protection, so the rear side should not remain openly exposed to long-term rain or water ingress.

The module’s IP rating does not automatically define the protection rating of the completed display. Long-term outdoor reliability also depends on the supporting frame or enclosure, module seams, connectors, cable entries, drainage, ventilation, grounding, lightning protection, power equipment, and installation workmanship. Always confirm the selected model and complete system design for the intended environment.

POF-S modules use an all-in-one silicone flexible back structure with magnetic alignment and M3 mechanical fixing. They are available in pixel pitches from P2.5 to P10 and support a broad range of curved outdoor displays, including detailed architectural features and larger-format advertising installations.

POF-SR modules combine a flexible PCB, silicone bottom case, protective rear cover, magnetic positioning, front installation, and front-service maintenance. They are available in P2.5, P3.076, and P4, with IP65-rated front protection and IP54-rated rear-cover protection.

Both platforms support controlled curved structures, but their protection ratings, brightness, LED packages, fixing methods, bending limits, service configurations, and minimum order quantities vary by model. Selection should be based on the project structure and the corresponding product specification.

POF Series modules can be integrated with compatible LED display control systems, but compatibility cannot be determined from the HUB75 interface or module dimensions alone. The data interface and pinout, scan rate, driver IC, receiving-card loading capacity, firmware, configuration file, signal routing, power connection, and calibration data must all be confirmed.

Before replacing modules or integrating them into an existing display, provide the receiving-card model, original configuration file, module label, PCB markings, connector photographs, scan configuration, and relevant system information for review. Modules from different models, manufacturers, configurations, or production batches should not be mixed unless mechanical, electrical, control, and calibration compatibility has been fully verified.

Concave or convex bending availability depends on the selected model, flexible PCB design, rear structure, permitted bending direction, included-angle definition, and minimum installation radius. A module should not be assumed to support bending equally in both directions.

Do not fold, twist, reverse-bend, sharply bend, or repeatedly flex a module unless the corresponding product specification explicitly permits it. The supporting frame should be fabricated to the required curvature before installation so the modules are not forced beyond their documented limit. Contact us with the required curve, screen dimensions, or cylinder diameter before finalizing the structure.

POF Series modules are suitable for engineered outdoor curved and cylindrical displays, media façades, architectural LED features, outdoor advertising screens, branded installations, public information displays, and other concave, convex, wave-shaped, or custom structures within the selected model’s documented limits.

Temporary outdoor event installations require suitable rain protection, wind-load resistance, structural reinforcement, grounding, drainage, protected electrical equipment, and safe service access. POF-SR models have IP54-rated rear-cover protection and should not be treated as suitable for unrestricted, permanently exposed rear-side installation without additional enclosure protection.

For elevated, overhead, façade, or publicly accessible installations, magnets should be used only for positioning and alignment. Project-appropriate mechanical fixing, safety restraints, and anti-fall measures must be incorporated into the engineered support structure.

The PI Series includes four indoor LED module platforms. PI-S uses conventional SMD technology and offers a practical balance of image quality, serviceability, and project cost. PI-G adds GOB surface protection to improve resistance to accidental impact, dust, static contact, and routine handling. PI-GI combines three 320×160mm GOB modules into one factory-integrated 320×480mm unit with a power supply, receiving card, daisy-chain cables, and mounting magnets for faster installation. PI-C uses Flip-Chip COB technology for higher contrast, improved surface uniformity, and premium close-viewing performance.

Selected PI-S and PI-G models are available as 1-piece sample packs for evaluation and replacement checks, with larger pack options available for project procurement. PI-GI and PI-C models are primarily supplied for bulk and project orders and may require a minimum order quantity. Available package quantities vary by model, so please check the product page or contact us before ordering. For replacement projects, compatibility and production-batch consistency should be confirmed before purchase.

Not necessarily. Matching the module size and pixel pitch alone does not guarantee compatibility. Cabinet dimensions, mounting points, magnet positions, power and signal connectors, scan configuration, driver ICs, receiving-card settings, calibration data, and production batch must also be checked. Before replacing modules or expanding an existing screen, please contact us with photos of the existing module and cabinet, the module label, control-system information, connector details, and the required quantity.

PI-S, PI-G, and PI-C are standard individual LED modules designed for integration with compatible cabinets, power supplies, receiving cards, and control systems. PI-GI is a factory-integrated 320×480mm GOB module assembled from three 320×160mm display sections and supplied with an integrated power supply, receiving card, daisy-chain cables, and mounting magnets. This reduces on-site wiring and assembly work, but a sending controller, supporting structure, power distribution, and project-specific cabling may still be required to build a complete LED display.

For close-viewing applications, begin with P2.0 or a smaller pixel pitch, such as P1.86, P1.53, or P1.25. PI-C is recommended for premium projects that prioritize high contrast, surface uniformity, and fine image detail. PI-G is suitable when close-viewing performance and additional surface protection are both important. PI-S is a cost-effective option for projects requiring fine pixel pitches with conventional SMD serviceability. The final choice should also consider viewing distance, content type, ambient lighting, camera use, installation structure, and budget.

The PO-S Series includes standard outdoor SMD modules for general fixed outdoor LED displays. The PO-G Series uses GOB-protected SMD technology to improve protection of the LED-facing surface. The PO-SR Series features an integrated rear-cover structure with IP65 front and IP54 rear protection and supports front and rear service. The PO-SD Series uses a double-sided IP65-rated structure with front-service access, while the PO-GD Series is designed for fine-pitch, high-density outdoor display applications. The most suitable series depends on pixel pitch, viewing distance, cabinet structure, protection requirements, and maintenance access.

PO Series modules are designed for outdoor applications, but protection ratings vary by model. Available structures include IP65-rated standard modules, IP65 front and IP54 rear-cover modules, and double-sided IP65-rated modules. A module-level IP rating does not automatically determine the protection level of the completed LED display. The cabinet, seals, connectors, cable entries, drainage, ventilation, grounding, and installation workmanship must also be properly designed for the operating environment.

A smaller pixel pitch provides higher pixel density and better image detail at closer viewing distances, while a larger pixel pitch is generally more economical for larger screens viewed from farther away. P1.53–P3 models are suitable for close-viewing outdoor information and commercial displays, while P4–P16 models are commonly selected for signage, façades, highways, stadiums, and large-format billboards. Required brightness depends on screen orientation, ambient light, installation location, viewing distance, and operating schedule. Always confirm the specifications of the selected model before ordering.

Not necessarily. Matching the module size and pixel pitch does not guarantee direct compatibility. Before replacement or expansion, confirm the cabinet opening, mounting points, screw or magnet positions, module thickness, power connector and polarity, data-interface type and pinout, scan configuration, driver IC, receiving-card settings, firmware, and calibration data. For the best brightness and color consistency, replacement modules should use the same confirmed configuration and, whenever possible, the same production batch as the existing screen.

Service access depends on the selected product. PO Series options include rear-service, front-service, and combined front-and-rear-service structures. Remote content updates, playback scheduling, system monitoring, and automatic brightness adjustment are functions of the complete LED display control system rather than the LED module alone. These functions require compatible receiving cards, controllers, communication hardware, sensors, software, and system configuration.

A small pixel pitch LED module has a very short distance between individual pixels (typically under 2.5 mm), resulting in a higher pixel density and finer image detail than standard modules. This makes it ideal for close-range viewing with smooth, high-resolution visuals.

Yes. Their fine pixel pitch and high resolution make small pixel modules ideal for close-range viewing environments such as meeting rooms, control rooms, or broadcast studios.

Yes. With high pixel density, small pixel pitch modules can achieve high or ultra-high resolutions such as 4K and even 8K in compact display sizes.

Yes. Fine pixel pitch LED modules are typically compatible with mainstream LED controllers and support common video input formats for easy system integration.

Yes. High-end NovaStar controllers such as the NovaStar VX1000 or TU4K Pro support 4K and higher pixel loading with HDR, making them suitable for large-scale high-resolution LED walls.

The controller sends video signals to receiving cards via sender boxes (such as MCTRL series), and the receiving cards drive the LED modules. Common connection interfaces include HUB75 and Ethernet.

Yes. With Nova Cloud or related software, NovaStar systems can support remote content updates, preview, and monitoring—ideal for distributed installations.

The sending card receives video input and transmits it to the receiving cards, which then send the data to the LED modules to display the image. Both are required for full LED display control.

A-series cards feature HDR optimization, high-load capacity, and support for advanced functions like calibration, smart module management, and 5G transmission readiness.

Yes. When choosing a controller, consider the total pixel count, resolution, and screen layout. Larger or high-resolution screens need controllers with higher pixel loading capacity to ensure stable performance and support for multiple inputs and screen splicing.

Colorlight controllers typically support interface inputs like HDMI, DVI, and SDI, and some also support USB or network inputs, making them compatible with computers, media players, and cameras.

The controller (or sending box) transmits processed video data via network cable or fiber optic to the receiving card, which then distributes it to LED modules, ensuring stable long-distance transmission and display.

Yes. With Colorlight Cloud or compatible software, users can remotely monitor display status (temperature, voltage, signal strength) and push content updates, making central management easier.

Yes. Combined with receiving cards, Colorlight controllers support multi-screen splicing, segmented display, and expanded layouts, suitable for large video walls and custom display configurations.

Yes. Mooncell systems support irregular screen structures, allowing module-level cropping and pixel extraction for seamless display on irregular shapes like circles, rings, or custom designs.

Yes. Using dedicated software or cloud platforms, remote monitoring and display content scheduling/updates are supported, helping centralized management of distributed screens.

The controller (e.g., Mooncell MVB10 2-in-1 LED Screen Video Controller) receives and processes input signals into display-ready data, while the receiving card (e.g., Mooncell A708 Receiving Card) takes that data and drives the LED modules. Both are required for the LED screen to operate.

Synchronous control displays content in real time, ideal for live video and large LED displays. Asynchronous control downloads content to the controller before playback, suitable for non-real-time ad loops or scheduled playback. Both are supported by Mooncell systems.

Yes. Mooncell offers dedicated setup and calibration software, such as AutoLED, for screen configuration, splicing adjustment, brightness and color calibration, and content import.

Huidu supports asynchronous playback (offline via USB/embedded storage) and cloud-scheduled playback, making it ideal for timed loops and remote content updates.

Key factors include screen resolution, total pixel count, and content demands. Smaller displays may be fine with lower-capacity models like A3L, while larger or more complex screens benefit from higher-capacity models such as A5L or A6L.

Yes. With Huidu’s cloud platform (e.g., XiaoHui Cloud) or software tools, users can remotely update content, schedule playback, and monitor device status, improving centralized management efficiency.

Yes. Huidu supports multi-screen synchronized playback, allowing the same or coordinated content to display across multiple screens for enhanced visual impact.

Huidu control systems are versatile and suitable for commercial advertising screens, corporate information displays, retail signage, outdoor billboards, and both standalone and multi-screen deployments.

The number of LED modules controlled by a receiving card depends on its pixel loading capacity. Typical receiving cards support around 256×256 to 512×512 pixels, which usually corresponds to multiple LED modules within a cabinet. Larger LED walls often use multiple receiving cards working together to control different sections of the screen.

A sending card is installed in the control computer or video processor and transmits video data to the LED display. The receiving card, installed inside each cabinet, receives that data and converts it into signals that drive the LED pixels. Together they form the core communication system of an LED display.

When selecting a receiving card, consider these key factors:

• Maximum pixel loading capacity
  
• Compatibility with LED control systems (NovaStar, Colorlight, Huidu, etc.)
  
• Number of RGB data groups or HUB ports
  
• Supported scan modes and driver IC types
  
• Refresh rate and grayscale performance
  

Choosing a card that matches your module specifications ensures stable performance and optimal image quality.

Yes. Most modern LED receiving cards support multiple scan modes such as static, 1/8 scan, 1/16 scan, or even higher scan ratios, allowing them to work with different LED module designs and driver ICs.

LED receiving cards are widely used in various LED display installations, including:

• Indoor LED video walls
• Outdoor advertising billboards
• Stage and rental LED screens
• Retail digital signage
• Control room display walls

These cards ensure accurate signal processing and stable image output across all LED panels.

Key factors include maximum pixel capacity, interface types, supported input formats (HDMI/DVI/DP/SDI, etc.), and compatibility with the control system, ensuring the model meets the display’s resolution and refresh requirements.

Yes. The processing capabilities of the sending card influence signal transmission. High-performance sending cards support higher refresh rates and more stable dynamic output, reducing flicker and dropped frames.

Most sending cards do not support hot swapping. Power should be off before inserting or removing cards to prevent damage or instability. Sending boxes may vary by design—refer to the manufacturer’s documentation.

Most sending cards support mainstream inputs such as HDMI, DVI, DisplayPort (DP), SDI, etc., and can receive signals from computers, media players, cameras, or image processors.

When selecting a sending card or sending box, consider the LED screen pixel requirements, input signal types, control system brand, and interface compatibility. High-performance sending cards also help improve refresh rate and dynamic image performance.

An LED video processor receives multiple signal sources (such as HDMI, DP, SDI, VGA), performs image scaling, splicing, and signal optimization, and outputs to the sending card/controller. This ensures the video matches the LED display’s resolution and layout.

Modern video processors typically support mainstream inputs such as HDMI, DisplayPort (DP), SDI, DVI, and VGA, and are compatible with signals from computers, media players, and cameras.

Screen resolution determines the number of pixels the video processor must handle. When selecting, ensure the processor’s maximum output capability is equal to or greater than the display’s resolution to prevent downsampling or distortion.

Yes. High-performance video processors better handle high-speed signals and high refresh rate outputs, reducing lag or flicker and enabling smooth dynamic visuals.

Ensure that the processor’s connections to the signal source, sending card, and display are secure, interfaces match correctly, and avoid long unamplified signal runs that can degrade quality. Also ensure stable power and proper cooling.
