Abstract
What is PD IEC TS 62977-3-1 - Electronic displays about?
PD IEC TS 62977-3-1 is the third part of an international standard used for electronic displays. By using PD IEC TS 62977-3-1 you can evaluate the performance of these devices which helps in manufacturing good image quality electronic displays. PD IEC TS 62977-3-1 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 differences. PD IEC TS 62977-3-1 the cross-industry measurement of the viewing direction dependence of colour displays. Several studies have indicated that the contrast ratio ( CR > 10:1) is, from a visual quality point of view, not useful to determine the viewing direction range for matrix displays. When colour differences are included in a viewing direction metric, the correlation between the metric value and a visual assessment value is significantly increased []. A more recent study revealed that a metric, combining viewing-direction related luminance degradation and colour deviation can accurately predict the relative change in the visual assessment value. This information is the basis for the determination of the viewing direction range, which has relevance from a visual quality point of view. Note: This document applies to colour matrix displays, which are based on transmissive or emissive technologies. Note: “ Viewing direction range” is sometimes referred to as “viewing angle”. Although technically incorrect, for legacy reasons the terms is considered equivalent .
