Шаг пикселя в наружных светодиодных светильниках: от P4 до P10, назначение каждого класса.

The Formula That Answers Every Pitch Question

Outdoor pixel pitch selection starts from one number you already have: the Минимальное расстояние просмотра — how close the nearest person will stand to the screen. The rule of thumb used across the industry is simple:

This is a conservative guideline, not a hard law — it already builds in a margin so the pixel structure is genuinely invisible at that distance. Reversed, it tells you what a given pitch buys: P10 resolves cleanly from about 10 metres, P6 from 6 metres, P4 from 4 metres.

P10 to P4: Matching Each Pitch to Its Scene

Here is how the standard outdoor pitch grades map to real installations. The “sweet spot” column is the scene each grade is genuinely built for — not a marketing tier.

The question is not “what is the best pitch?” but “how close can someone get?” Answer that, and the pitch grades sort themselves out in under a minute.

Fine Pitch Outdoor: The FO Series and the Semi-Outdoor Edge Case

Outdoor LED used to mean “big pitch, far away.” That changed with semi-outdoor environments — covered transit concourses, retail canopies, and kiosk-scale screens where people stand within two metres. At that distance, P4 or P6 shows visible pixel structure, and you need fine pitch.

The FO Series covers P1.2 to P2.5 for exactly these situations. Because it is viewed up close, it pairs fine pitch with IP66 protection on both faces — these screens get cleaned and touched far more than a billboard thirty metres up. The trade-off is brightness: FO runs at 3,500–4,000 nits, which is correct for covered or semi-outdoor light but not for direct midday sun.

Pitch Is Not Resolution — Don’t Confuse Them

A common mistake is treating pixel pitch as a quality score, where a smaller number is always better. Pitch is a плотность, not a total. Resolution is the product of pitch and physical size, and a large P10 wall can carry more total pixels than a small P4 wall.

Two consequences follow. First, finer pitch drives up processor and cabling cost — more pixels per cabinet means more receiving cards and more data. Second, a billboard viewed from 30 metres shows нет visible difference between P6 and P4, yet P4 costs noticeably more per square metre and needs more processing. That is wasted budget.

The Cost Curve: Why Finer Pitch Costs More Than You Think

Finer pitch raises cost in three compounding ways, and the third is the one most buyers miss:

1. More LEDs per square metre. Halving the pitch quadruples the LED count. A P4 panel carries roughly six times the LEDs of a P10 panel of the same size.
2. More receiving cards and processing. Each card drives a fixed pixel budget. Finer pitch means more cards per wall and a higher-spec video processor.
3. Higher mounting and structural cost. Finer-pitch cabinets are denser and often heavier per square metre, which affects the steel structure and installation labour.

This is why the honest recommendation is the coarsest pitch that still resolves cleanly at your minimum viewing distance — not the finest one you can afford. See how all these variables stack into the final figure in our cost-composition guide.

Two Numbers, and an Engineer Hands You the Spec

You do not need to become a pixel-pitch expert. You need two numbers, and a supplier who can turn them into a recommendation in the same day:
