06 / FAQ
Common questions
What clients and integrators usually ask.
Does a smaller pixel pitch always mean a better image?
Not necessarily. A smaller pixel pitch increases pixel density and can make the image look smoother at close range, but the benefit depends on the viewing distance. At a 10 m viewing distance, the human eye cannot resolve the difference between a 1.2 mm and a 2.6 mm pitch; both will appear sharp. Choosing an unnecessarily small pitch raises cost without a visible improvement. The right pitch is the smallest one that still meets your minimum viewing distance and content requirements, not the smallest available.
How do I balance pixel pitch with budget?
Balance is about matching pitch to the closest viewer and the content type. For a 2 m viewing distance, you need a pitch around 1.2 mm or finer; for 5 m, 2.6 mm may suffice; for 10 m, 4 mm or larger can work. Smaller pitches cost more per square meter and often require more processing power. A practical approach is to select the largest pitch that still delivers acceptable sharpness at the closest viewing distance, then verify with a demo or simulation. This keeps costs in line without sacrificing perceived quality.
Can I use a larger pitch if I only show video or graphics?
Yes, but with caveats. Video and graphics with large text or simple shapes can tolerate a larger pitch because the eye is less likely to notice pixelation. However, if the content includes fine text, detailed maps, or high-frequency patterns, a smaller pitch is safer. The viewing distance remains the primary factor; even with simple content, a viewer at 2 m will see individual pixels on a 2.6 mm pitch. Always test with your actual content at the intended distance.
What is the role of content resolution in choosing pixel pitch?
The source resolution should match the display's native resolution as closely as possible. If the source is lower than the panel's native resolution, the image may appear soft or require scaling. If the source is higher, the display may not show all details. For a given viewing distance, the pixel pitch determines the maximum resolvable detail. For example, a 1.25 mm pitch has a native resolution of 640,000 dots per square meter, which can show fine detail at close range. Matching content resolution to the panel's native resolution helps avoid unnecessary upscaling or downscaling artifacts.
Are there any industry standards for pixel pitch and viewing distance?
There is no universal standard, but many manufacturers provide a "minimum viewing distance" or "best viewing distance" in their specifications. For instance, the manufacturer lists minimum viewing distances for its products: a 1.25 mm pitch has a best viewing distance of about 2.13 m, a 0.9375 mm pitch about 1.875 m, and a 2.976 mm outdoor pitch about 3 m. These figures are based on the pixel pitch and serve as practical guidelines. Always verify with the manufacturer's data for the specific model you are considering.
How does ambient light affect pixel pitch choice?
Ambient light influences brightness and contrast requirements, which can indirectly affect pitch selection. In bright environments, you may need a higher brightness LED, which often comes with a larger pitch. For indoor low-light settings, smaller pitches with lower brightness are common. For example, the manufacturer's indoor GT1.5 has a brightness of 600 nits after calibration, while outdoor UM2.976 offers 4000 nits. The pitch itself is not directly tied to ambient light, but the overall system design must balance brightness, contrast, and pitch to achieve good visibility.
Can I upgrade to a smaller pixel pitch later?
Upgrading to a smaller pitch typically requires replacing the entire LED panel or cabinet, as the pixel pitch is fixed by the physical LED layout. This can be costly and may involve structural changes. It is more economical to choose the right pitch from the start, considering future content and viewing distance needs. If you anticipate closer viewing or higher resolution content in the future, selecting a smaller pitch now can save upgrade costs later.
What are the most common mistakes when choosing pixel pitch?
Common mistakes include: selecting a pitch based on the largest viewing distance only, ignoring the closest viewer; choosing the smallest pitch available without considering budget; overlooking content type and resolution; and not verifying the manufacturer's recommended viewing distance. Another mistake is assuming that a higher pixel density always means better quality, which is not true if the viewing distance is large. Always evaluate the actual viewing environment and content before deciding.
