IEC 62906-5-3:2021

Overview

IEC 62906-5-3:2021 is an international standard that defines measuring methods of image quality for full‑frame laser projection displays (LPDs). It specifies standard measurement conditions, test patterns, and procedures to determine key image quality parameters for laser display devices that integrate projector and screen (front and rear projection). The standard explicitly excludes raster‑scanned (flying‑spot) projection devices.

Key topics and technical requirements

The standard covers practical test methods and required conditions to ensure repeatable, comparable image quality measurements for laser projection displays:

• Scope and exclusions: applies to full‑frame laser projection displays (front and rear screens included); flying‑spot projectors excluded.
• Standard measuring conditions:
  • Environmental: temperature 25 °C ± 3 °C; relative humidity 25–85 % RH; atmospheric pressure 86–106 kPa.
  • Power supply: rated voltage ± 0.5 % and frequency ± 0.2 %.
  • Warm‑up time: measure after light output stabilizes - defined as when repeated 1‑minute‑interval measurements over ten minutes show
