LED Grids 101: Pixel Pitch, Refresh & IP Rating Explained

Meta Description: Match pixel pitch to viewing distance, pick the right IP rating & save up to 23 % on CAPEX. Spec sheet template included.

  1. Why Pixel Pitch Matters Pixel pitch (mm) = center-to-center LED distance. Smaller = higher resolution = higher cost.
  2. Viewing Distance Rule of Thumb | Pitch (mm) | Min Viewing (m) | Typical Use | |————|—————–|————-| | 1.2 | 3 | Indoor selfie wall | | 2.5 | 6 | FEC arena backdrop | | 4.0 | 10 | Outdoor façade |

  1. IP Ratings: Outdoor vs Indoor • Indoor: IP30 (dust only)
    • Covered outdoor: IP54 (rain splash)
    • Full outdoor: IP65 (jet spray) + UV-stable mask
    Cost delta: IP30→IP65 ≈ +28 %.
  2. Refresh Rate & High-Speed Cameras • 1 920 Hz: standard content
    • 3 840 Hz: slow-motion replay & broadcast
    Rule: refresh ≥ 20 × frame rate (e.g., 120 fps × 20 = 2 400 Hz).
  3. Controller Compatibility Matrix | Controller | Max Pixels | HDR | Price | |————|———–|—–|——-| | Novastar MCTRL4K | 4 M | No | US $1 100 | | Brompton Tessera SX40 | 8 M | Yes | US $3 900 | | Colorlight S4 | 2.3 M | No | US $650 |
