Organization: IEC
Publication Date: 1 April 2016
Status: active
Page Count: 34
ICS Code (Electronic display devices): 31.120
scope:

This part of IEC 62715, which is a technical specification, specifies the general rules and the details of optical measuring methods from a fixed point (the so-called vantage point) for curved emissive and transmissive type displays such as OLED and LCD in dark room conditions. This document focuses on concave shape large screen displays (non-portable) around a horizontal and/or vertical axis with fixed or variable curvature radius.

The measuring method stipulated in this technical specification is applied to the curved display modules under the following states:

• vantage-point luminance variation by viewing angles

• vantage-point contrast ratio variation by viewing angles

• vantage-point chromaticity variation of white colour by viewing angles

• vantage-point colour gamut area variation by viewing angles

• vantage-point chromaticity variation of primary colours by viewing angles

• luminance uniformity and its uniformity variation by viewing angles

• chromaticity uniformity and its uniformity variation by viewing angles

• viewing angle of half-luminance

• viewing angle of half-contrast
