Scope

This part of ISO 9241 aims to help designers measure screen reflections that might affect user comfort and task performance when using display screen equipment. It specifies requirements and methods to measure image quality in lighting environments that can cause specular and diffuse reflections from the screen. The requirements cover: image luminance ratio with reflections; specular reflection luminance ratio; reflection control method and effect on image quality; and the reference luminous environment. The standard includes a detailed section describing how to measure and calculate reflections. The standard also includes four annexes: an alternative, performance-based test method; a graphical report format; a worked example; and a bibliography.

Audience

This is a technical standard that assumes a good working knowledge of light measurement. The main audience is display engineers who want to make sure that anti-reflection treatments do not degrade image quality.
