IEC 62922:2016

Overview

IEC 62922:2016 is an international standard established by the International Electrotechnical Commission (IEC) that specifies performance requirements for organic light emitting diode (OLED) panels and tiles intended for general lighting applications. This standard applies to OLED devices designed for indoor environments powered by DC supplies up to 120 V or AC supplies up to 50 V at 50 Hz or 60 Hz. It provides a framework for testing, characterization, and reliability assessment to ensure high-quality and consistent performance of OLED lighting panels.

As OLED technology continues to revolutionize energy-efficient lighting solutions, IEC 62922:2016 plays a critical role in defining test parameters and performance benchmarks, facilitating the development and adoption of OLED panels in general lighting markets worldwide.
