Overview

EN 62922:2017/A1:2021 (adoption of IEC 62922:2016/AMD1:2021) sets amended performance requirements for OLED panels for general lighting. Published by CENELEC/CEN and adopted as a national standard in Europe, this Amendment A1 updates definitions, test methods, marking requirements and limits for maintained photometric and electrical characteristics of OLED tiles and panels used in general lighting applications.

Key topics and technical requirements

• Definitions added: median useful life, maintained operating voltage, and maintained chromaticity coordinate - used for lifetime, voltage stability and color stability claims.
• Marking / product information (mandatory on packaging or product literature):
  • Rated luminous flux (lm), average luminance (cd/m2), rated chromaticity coordinates (u’v’) and chromaticity range, correlated colour temperature (K), rated colour rendering index, operating temperature range, rated luminous efficacy (lm/W), luminance uniformity (%), luminous intensity distribution, surface chromaticity uniformity and measurement spots, rated light output surface size/location, rated median useful life (h), luminous flux maintenance (%), maintained operating voltage (V), and maintained chromaticity coordinate.
• Chromaticity: colour coordinates must be calculated from spectral distribution using ISO 11664-5/CIE S 014-5/E:2016 (u’v’).
• Luminance:
  • Initial average luminance measured per Annex G.
  • Compliance: initial average luminance must not deviate from rated average luminance by more than ±10%.
  • Annex G specifies measurement methods: imaging luminance measuring device (ILMD) or spot luminance meter; ILMD excludes a 3 mm edge zone.
• Maintained photometric characteristics:
  • Luminous flux maintenance: measured at rated life (or estimated via accelerated life tests with manufacturer-provided method). Compliance requires evaluated flux maintenance at rated life to be ≥ 90% of the rated maintenance factor.
  • Maintained operating voltage: manufacturers must declare values at 2 000 h and the maximum lifetime operating voltage; measured voltage at 2 000 h shall not exceed the declared value.
  • Maintained chromaticity: initial and 2 000 h chromaticity measured; shift can be expressed as Δ(u’,v’). Panels shall not exceed the rated chromaticity shift.
• Environmental stress test:
  • High temperature – high humidity storage: (90 ± 5)% RH at (60 ± 2) °C for 500 h, unpowered, no condensation; measure luminous flux and chromaticity after test.
• Controlgear design: guidance provided in Annex E for compatible drivers/controlgear to ensure proper operation.

Applications and who uses this standard

• OLED panel and tile manufacturers - product design, performance claims, labeling and lifetime statements.
• Luminaire and lighting system designers - component selection, controlgear compatibility and thermal/humidity resilience.
• Test laboratories and conformity assessors - standardized test procedures (flux, luminance, chromaticity, humidity stress).
• Specifiers, purchasers and compliance officers - writing procurement specifications, comparing products, verifying warranty and lifetime claims.

Related standards

• IEC 62922 (base international standard for OLED panels)
• ISO 11664‑5 / CIE S 014‑5 / E:2016 (colourimetry - u’v’)
• IEC 62717 (LED lifetime metrics referenced for guidance)

Keywords: EN 62922:2017/A1:2021, IEC 62922, OLED panels, performance requirements, luminous flux maintenance, chromaticity, luminance uniformity, high temperature high humidity, median useful life, maintained operating voltage.

AMENDMENT 1
FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.
