Abstract

ISO DIS9241 Part 7 describes the requirements of display reflection for CRTs an some flat panels (emissive displays whose colour and luminance contrast do not vary strongly as a function of the viewing direction). The Japanese member body of ISO TC159 SC4 has been contributing to the Part 7 measurements. In 1996, some issues of the reflection measurement were pointed out at the ISO TC159 WG2 meeting and SID conference. The issues are the uncertainty of the evaluation method. It is reported to what degree the issues affect the Part 7 measurement requirement, showing the results of actual experiments for CRTs and LCDs. The goal is to verify that the ISO DIS9241 Part 7 method has an effective certainty from an ergonomic point of view.
