IEC/TS 62715-5-2 Ed. 1.0现行

IEC TS 62715-5-2:2016(E) 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.
