What is Pixel Pitch in LED Displays?
Pixel pitch refers to the distance (in millimeters) between the centers of two adjacent LED pixels on a display. It's the primary factor determining image clarity and optimal viewing distance.
Key Details:
1. Measurement
- Expressed in millimeters (e.g., P1.2, P2.5, P4, P10)
- Smaller number tighter pixel spacing higher resolution
2. Viewing Distance Formula
Optimal viewing distance (meters) ≈ Pixel pitch (mm) × 2~3
Example: A P3 screen is best viewed from 6-9 meters away
3. Common Applications by Pitch
Pixel Pitch | Typical Use Case |
| P0.9-P1.5 | Broadcast studios, luxury retail |
| P1.6-P2.5 | Corporate lobbies, control rooms |
| P2.6-P4 | Indoor signage, event venues |
| P5-P10 | Outdoor billboards, stadiums |
4. Trade-offs
- Smaller pitch:
Higher resolution
Higher cost
Increased power consumption
- Larger pitch:
More affordable
Better for long-distance viewing
Lower pixel density
Pro Tip:
For boardroom installations, P1.8-P2.5 balances cost and clarity. Outdoor digital signage typically uses P6-P10 for better visibility at 20+ meters.
Technical Note: Pixel pitch directly affects:
- PPI (pixels per inch)
- Cabinet size (smaller pitch requires more modules for same screen size)
- Content requirements (higher pitch needs simpler graphics)
