This part of IEC 62977 specifies the evaluation method of the viewing direction characteristics of electronic display devices under dark-room conditions. More specifically, this document focuses on the evaluation of the viewing direction characteristics based on colour difference.<\/p>\n

This document applies to colour matrix displays, which are based on transmissive or emissive technologies.<\/p>\n
