Ⅵ. Accuracy Benchmarks
| Parameter | Consumer Grade | Broadcast Grade | Tolerance |
|---|---|---|---|
| Brightness Uniformity | ±15% | ±3% | ±1% (ISO 29113) |
| Color Uniformity (ΔE) | 5.0 | 1.0 | 0.8 (SMPTE RP431-2) |
| White Balance Error | ±500K | ±50K | ±30K (ITU-R BT.1886) |
Ⅶ. Pricing & Recommendations
| Use Case | Recommended Toolkit | Budget |
|---|---|---|
| Virtual Production Stage | Klein K10-A + Tessera BRMT + Radiant Y23 | $45,000+ |
| Outdoor Mesh Façade | Sekonic C-800 + NovaStar AGS Pro + JETI DualPath | $22,000 |
| Retail Transparent Display | Konica CA-410 + Colorlight CL-2000 | $8,000 |
Pro Tips for Mesh Screens
- Calibrate Installed Position
Curvature/tension affects LED angles → Never bench-calibrate flexible mesh. - Black-Level Optimization
Set black output to 0.02 nits max to maintain transparency depth. - Gap Exclusion Protocol
Tag non-LED areas in software to prevent false measurements.
📌 Critical Warning: Using consumer colorimeters (e.g., SpyderX) on LEDs causes >30% error due to non-standard LED spectra. Always use LED-optimized tools.
Where to Rent/Service:
- Rental: VER (Video Equipment Rentals), PRG
- Calibration Services: Leyard OnSite ($15-50/m²), SMS Electronics (UK/EU)
For mission-critical projects, budget 3-5% of screen cost for annual calibration.
