Question

Can the P6 LED display be spliced ​​with other models or brands of display screens?

Answer 1

Regarding whether a P6 LED display can be combined with other models or brands of displays, several key technical points need to be analyzed:

1. Pixel Pitch Matching

P6 indicates a pixel pitch of 6mm.

If the other screen you are combining has a different pixel pitch (such as P4 or P8), the overall image will be inconsistent in detail and clarity.

Result: The image may appear pixelated or uneven; it is not recommended to directly combine screens with different pixel pitches.

2. Driver Chip and Refresh Rate

Different brands or models of LED screens may use different driver chips and refresh rates.

If the refresh rates are inconsistent:

The image may flicker or tear;

Color display may be inaccurate.

For screen splicing, it is best to ensure that the refresh rate, grayscale, brightness, and scanning method are consistent.

3. Control System Compatibility

LED screens are controlled by a control card to output image signals.

If combining screens of different brands:

Does the control card support mixed models?

Can the control software recognize modules with different resolutions?

In most cases, it is difficult for the same control system to drive screens of different brands, which can easily lead to inconsistent colors and display.

4. Physical Size and Splicing

When splicing, module size, bezel thickness, and installation accuracy need to be considered.

Even if the technical parameters match, differences in physical size may lead to noticeable gaps, affecting the overall visual effect.

✅ Summary

It is strongly not recommended to directly combine P6 screens with other models or brands of screens.

If splicing is necessary:

Ensure the same pixel pitch;

Use the same brand or compatible models;

The control system and refresh rate must be consistent;

The physical dimensions should be matched as closely as possible during installation.

Answer 2

Whether a P6 LED display can be combined with other models or brands of displays depends on several factors, primarily panel size, driver board compatibility, hardware parameter consistency, and calibration processing.  A detailed analysis is as follows:

I. Conditions for Successful Splicing

Panel Size and Driver Board Compatibility: If the P6 LED display and other models or brands of displays have the same panel size and compatible driver boards, splicing is theoretically possible. However, this is relatively rare in practice, as different brands and models of displays often have differences in hardware design.

Consistent Hardware Parameters: In addition to panel size and driver board compatibility, it is also necessary to ensure that key parameters such as brightness, contrast, and color temperature are consistent or similar to avoid noticeable color differences or brightness variations after splicing.

II. Situations Where Splicing is Not Possible or the Effect is Poor

Hardware Design Differences: Different brands and models of LED displays may have differences in hardware design, such as LED arrangement and driver circuit design. These differences may lead to uneven display and color distortion after splicing.

Software Compatibility Issues: Different brands of LED displays may use different control software and protocols, which may prevent synchronous control or data transmission during splicing, thus affecting the splicing effect.

Color Difference Issues: Even with consistent hardware parameters, different batches of LED display modules may have color differences due to manufacturing processes and material variations. This color difference may become more pronounced after splicing, affecting the overall display effect.

III. Practical Cases and Solutions

Practical Case: Some users have attempted to splice a P6 LED display with other models of displays, but found that due to hardware design differences and software compatibility issues, uneven display and color distortion occurred after splicing.

Solutions:

Choose Compatible Products: When purchasing LED displays, prioritize products with good compatibility and ease of splicing. This can reduce future splicing problems and costs.

Perform Pixel-by-Pixel Calibration: For different models or brands of LED displays that have already been purchased, if splicing is required, consider performing pixel-by-pixel calibration. Pixel-by-pixel calibration can significantly reduce color differences and improve the display effect after splicing.

However, it should be noted that pixel-by-pixel calibration requires professional equipment and personnel, and may not completely eliminate all color differences. Consult with technical professionals: Before splicing, it is recommended to consult with technical professionals or the original manufacturer to ensure a smooth system transition and optimal display performance.

Answer 3

Combining P6 LED displays with other models or brands typically presents technical challenges, and feasibility highly depends on the consistency of specific specifications.

The feasibility of splicing primarily depends on the matching of key parameters. Splicing may be possible if the target display is completely identical to the P6 model in the following aspects:

- Physical dimensions and structure: Module dimensions (such as the P6's 192mm × 192mm), cabinet structure, and splicing method (such as magnetic or quick-lock) must be compatible; otherwise, it will lead to uneven seams or installation problems.

- Electrical interfaces: The driver board, power interface (such as 5V DC), and signal connectors (such as HUB board pin definitions) must be standardized and matched; otherwise, it may cause short circuits or signal errors.

- Display parameters: Pixel pitch (P6 is 6mm), pixel arrangement, and refresh rate must be the same; otherwise, it will result in display misalignment, uneven color, or gaps.

Splicing across different brands or models carries significant risks. Different brands or non-identical product series usually have differences in module design, driver board protocols, or cabinet manufacturing processes. Direct splicing can easily lead to:

- Excessive or uneven splicing gaps

- Reduced color consistency

- Hardware failures (such as short circuits caused by mismatched interfaces)

For example, P3 modules and P4 modules cannot be directly interchanged due to different pixel pitches (3mm vs. 4mm).

Exceptions and recommendations. Products from the same brand and series that use standardized cabinet designs (such as magnetic structures and universal interfaces) may support modular replacement, but this requires explicit support from the manufacturer. In practical applications, it is recommended to prioritize using the same model or brand of products to ensure compatibility; if mixing is necessary, the consistency of the above parameters must be strictly verified, and a risk assessment should be conducted in consultation with the technical supplier.

Answer 4

Answer: Yes, it can be spliced.

Feasibility of splicing P6 LED displays with other models or brands:

Splicing is possible, but the prerequisite is that multiple screens maintain consistency in key parameters and system architecture, or can be controlled uniformly. P6 only indicates a pixel pitch of 6 mm and does not specify the brand, scanning method, grayscale, refresh rate, cabinet size, etc. These differences will directly affect cross-screen consistency, synchronization, and stability. In engineering, "same brand, same series, same batch" networking is more recommended; cross-brand/cross-model mixing requires checking compatibility item by item and verifying through joint debugging before delivery.

Key Compatibility Conditions Checklist

Pixels and Resolution

Pixel pitch must be consistent (e.g., both P6), otherwise, "physical pixel misalignment," "scaling and stretching," or "black border" problems will occur.

Module/cabinet resolution must be consistent or an integer multiple (e.g., both 192×192 mm modules, or the cabinet resolution is divisible by an integer), facilitating unified splicing and scaling strategies.

Scanning and Driving

Scanning method (e.g., 1/8 scan), driver IC, and grayscale level (e.g., 4096 levels) must be consistent to avoid inconsistencies in brightness, dark field, ghosting, and refresh performance.

Refresh Rate and Grayscale

Refresh rate (e.g., 120/180/≥3840 Hz) and grayscale level must be consistent to ensure smooth, tear-free, and continuous color gradation across screens.

Brightness and Color Gamut

White balance brightness and color temperature adjustable range must be consistent (e.g., 6000 cd/㎡, 3200–9300 K), facilitating unified color calibration and brightness balance for the entire screen.

Cabinet and Installation

Cabinet size and mounting hole positions must be consistent (e.g., 576×576 mm or 480×480 mm) to achieve seamless splicing and flatness control; consistent module masks and optical characteristics can reduce bright and dark lines at the splicing seams.

Control System and Interface

Use the same manufacturer/same generation control system (sending card/receiving card/network cable or fiber optic transmission), with unified resolution, frame rate, and mapping; common interfaces include DVI/HDMI/3G-SDI/SDI, etc. Cross-brand compatibility requires confirmation of protocol and control software compatibility. Situations where mixing different technologies or requiring extra processing is not recommended:

Mixing different technological approaches: For example, LED and LCD video walls use different display technologies, resulting in physical gaps, differences in brightness/color gamut/refresh mechanisms, and are usually not treated as a single logical screen for unified display (unless a super-high-resolution server is used for image splitting and independent output, but the boundaries will still be visible).

Significant parameter differences: Mixing P6 with P8/P10 will lead to scaling and jagged edges due to different pixel densities; inconsistent scanning methods/grayscale/refresh rates will cause inconsistencies in brightness and motion images; different cabinet sizes/mounting hole positions will increase the risk of gaps and unevenness.

Implementation and Acceptance Recommendations:

Planning Stage: Require the manufacturer to provide a key parameter table (pixel pitch, module/cabinet size, scanning, grayscale, refresh rate, brightness, color temperature, interface and control protocol), and create a "mixed-technology compatibility matrix".

Stocking and Commissioning:  Try to obtain all components from the same batch; after delivery, perform parameter verification and initial color gamut/brightness calibration for each cabinet and board; during full-screen commissioning, unify the resolution, frame rate, and mapping, and perform regional brightness and chromaticity fine-tuning if necessary.

Acceptance Criteria: Check for consistent brightness/color across screens, no tearing during refresh, no banding at low grayscale levels, no bright or dark lines at the seams, and ensure flatness and geometric errors are within the manufacturer's specifications; for critical applications, a 24-72 hour continuous operation stability test is recommended.

Answer 5

Answer: It's possible to splice them together, but it's not recommended.

Reasoning:

It's generally not recommended to mix and match P6 LED displays with screens of other models or brands. Although physical connection might be possible under a few specific conditions, consistent display performance cannot be guaranteed.

Background

The "P6" in an LED display refers to its pixel pitch of 6 millimeters, which is the distance between each pixel. This value directly affects the screen's resolution, clarity, and optimal viewing distance. Different models (such as P4, P5, P8) have different pixel pitches, and different brands may use different driver chips, control systems, color calibration algorithms, and signal processing technologies.

When attempting to splice different models or brands of LED screens together, the core challenge is ensuring that the entire large screen displays a uniform image with consistent color, synchronized refresh rate, and no tearing.

Key Limitations and Analysis

The following are the main factors that make mixing and matching difficult:

Resolution and pixel density mismatch: P6 has approximately 27,777 pixels per square meter, while the finer P4 has as many as approximately 42,000 pixels/㎡. Forcing them together will result in localized blurring or stretching of the image.

Differences in control systems: The sending cards, receiving cards, and control software used by different brands are often incompatible. For example, mainstream control systems such as Linsn, NovaStar, and Colorlight are difficult to seamlessly integrate.

Poor color and brightness consistency: Even if they are all full-color screens, LED lamp beads from different batches and manufacturers (such as SMD2727) have differences in white balance, color temperature, and brightness decay characteristics, resulting in a noticeable "patchwork effect" after splicing.

Different refresh rates and grayscale processing: High-end screens support high refresh rates (such as 1920Hz and above) and 16-bit grayscale processing, while lower-end products may only support lower parameters, causing motion blur or a lack of detail in dynamic images. Dimension | P6 Screen Self-Splicing | Mixing Different Models (e.g., P6 + P4) | Mixing Different Brands (e.g., Brand A P6 + Brand B P6)

Physical Splicing Feasibility | ✅ Fully feasible, standard cabinet design | ⚠️ May be limited due to size differences | ⚠️ Depends on universal structure, partially achievable

Resolution Consistency | ✅ Completely consistent | ❌ Significant differences, image distortion | ✅ Basically consistent with the same pixel pitch

Control System Compatibility | ✅ Unified control from the original manufacturer | ❌ Almost impossible to synchronize | ⚠️ Requires a third-party controller or protocol conversion

Color/Brightness Uniformity | ✅ Factory calibrated, good consistency | ❌ Significant differences | ⚠️~❌ Large differences without cross-calibration

Recommended for Actual Application | ✅ Highly recommended | ❌ Not recommended | ⚠️ Use with caution in very specific scenarios

Theoretically, if two P6 screens from different brands use the same driver IC (such as MBI5124), the same scanning method and control protocol, and are controlled by a professional-grade video processor (such as the Novastar VX series) for unified signal distribution and pixel-by-pixel brightness correction, a勉强 splicing might be achievable at extremely high cost and technical investment, but this is not a conventional operation.

✅ Correct Practices and Recommendations

Prioritize using products of the same brand and model for splicing to ensure optimal visual effects and ease of maintenance.

If you need to expand an existing screen, try to contact the original manufacturer or supplier to obtain matching modules.

When it is necessary to integrate old equipment, consider using an independent video wall controller to drive multiple sets of screens separately, managing them as multiple logical partitions rather than seamless physical splicing.

For rental LED display projects or temporary LED display projects, choose brands with strong industry universality (such as Qiangli Jucai, Unilumin, Absen), as their ecosystem compatibility and technical support are more comprehensive.

Answer 6

P6 LED displays can be combined with other models or brands of displays, but certain conditions must be met, as follows:

1. Pixel Pitch Matching: If different models or brands of LED displays have the same pixel pitch (P-value) (e.g., both P6), they can be directly combined. The clarity and uniformity of the combined image will be essentially the same. If the pixel pitch is different (e.g., P6 with P4, P8, etc.), there may be differences in image granularity or boundary inconsistencies after splicing, requiring software or hardware correction to optimize the display effect.

2. Consistent Physical Dimensions and Module Specifications: The module size (e.g., 320mm × 160mm) and cabinet thickness of the displays must be consistent to ensure a flat physical connection during splicing and avoid gaps or height differences. Different brands or models of displays may have different module sizes, which need to be confirmed or adapted in advance.

3. Compatible Signal Transmission and Control System: The displays used for splicing must support the same signal transmission protocol (such as DVI, HDMI, SDI, etc.) and control system to ensure synchronized display and control. Different brands or models of displays may use different control cards or software; compatibility needs to be confirmed or system integration adjustments may be required.

4. Color and Brightness Consistency: Different brands or models of LED displays may have differences in color reproduction and brightness uniformity. Before splicing, the displays need to be color calibrated and brightness matched to ensure consistent color and uniform brightness in the combined image, avoiding color differences or brightness variations.

In summary, splicing P6 LED displays with other models or brands of displays is feasible, but it requires comprehensive consideration of factors such as pixel pitch, physical dimensions, signal transmission, and color brightness, and professional debugging to ensure the splicing effect. It is recommended to communicate with the supplier to confirm compatibility before splicing and have professional technicians perform the installation and debugging.
