WG 18 - TC 110/WG 18

IEC 62341-6-1:2025 specifies the standard measurement conditions and measuring methods for determining the optical and electro-optical parameters of organic light emitting diode (OLED) displays. Except for the power consumption method, all methods are intended for unbounded input signals measured in the flat regions of the display in a dark room. This fourth edition cancels and replaces the third edition published in 2022. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
- The standard average picture level (APL) RGBCMY test pattern is modified, and the variable signal loading RGBCMY test pattern is added.
- Chromaticity gamut area and colour gamut volume are modified.

IEC 62341-6-7:2024 specifies the standard measuring conditions and measuring methods for determining the optical characteristics of an OLED display with under-screen camera; other under-screen features, such as under-screen fingerprint or under-screen time of flight (TOF) can also be applied. This document applies to OLED displays such as mobile phone, monitor and TV with under-screen features.
NOTE Under-screen feature will want the display to be partially transparent and partially non-transparent, and this can be achieved only by certain types of display technology, for example OLED. This document mainly focuses on OLED display with under-screen feature.

IEC 62341-6-1:2022 specifies the standard measuring conditions and measuring methods for determining the 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 edition includes the following significant technical changes with respect to the previous edition:
- measuring methods for power consumption of displays that have an embedded video connection terminal are added;
- the contents description including video signal for power consumption is modified.

IEC 62341-5-3:2019 specifies the standard measuring methods for determining the image sticking and lifetime of organic light emitting diode (OLED) display panels and modules, except finalized display products for end customers, such as TV sets, monitor sets and mobile phones. The measuring method for the lifetime mainly applies to modules.
This edition includes the following significant technical changes with respect to the previous edition:
a) the measurement vehicle for lifetime is only for the module;
b) the measurement method for monitor or TV devices is modified;
c) the digital signage display is included as an example of OLED devices;
d) the measurement method with HDR (high dynamic range) for image sticking is added;
e) the analysis method with CIEDE 2000 is added for image sticking;
f) the information method for evaluating image sticking is modified.

IEC TS 62341-6-5:2019 (E) specifies the standard measurement conditions and dynamic range properties for OLED display panels and modules. More precisely, this document focuses on the specific aspects of the dynamic range properties.

IEC 62341-5-2:2019 defines test methods for evaluating the mechanical endurance quality of organic light emitting diode (OLED) display panels and modules or their packaged form for transportation. It takes into account, wherever possible, the environmental test methods outlined in IEC 60068 (all parts). The object of this document is to establish uniform preferred test methods for judging the mechanical endurance properties of OLED display devices.
This edition includes the following significant technical changes with respect to the previous edition:
- Vibration and shock tests for large displays (for example, TVs and monitors) are added.
