IEC 62341-6-1:2017 RLV contains both the official IEC International Standard and its Redline version. The Redline version is not an official document, it is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition.

IEC 62341-6-1:2017(E) specifies the standard measurement conditions and measuring methods for determining optical and electro-optical parameters of organic light-emitting diode (OLED) display modules and, where specified, OLED display panels. These methods are limited to flat displays measured in a dark room.
This second edition cancels and replaces the first edition published in 2009. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a)  extends the applicability of the measuring methods to include OLED displays that have multi-primary or red, green, blue and white sub-pixels,
b)  adds a method to characterize how the luminance is affected by the amount of content on the screen,
c)  adds a method to determine the dark room colour gamut volume in the CIELAB colour space.
