FLEXIBLE ORGANIC LIGHT EMITTING DIODE (OLED) PANELS
FOR GENERAL LIGHTING – PERFORMANCE REQUIREMENTS
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 IEC Publication may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.

43 FOREWORD
44 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national
45 electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all
46 questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC
47 publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and
48 Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC
49 National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental
50 and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with
51 the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the
52 two organizations.
53 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus
54 of opinion on the relevant subjects since each technical committee has representation from all interested IEC National
55 Committees.
56 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in
57 that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC
58 cannot be held responsible for the way in which they are used or for any misinterpretation by any end user.
59 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to
60 the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and
61 the corresponding national or regional publication shall be clearly indicated in the latter.
62 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment
63 services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by
64 independent certification bodies.
65 6) All users should ensure that they have the latest edition of this publication.
66 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its
67 technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature
68 whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of,
69 or reliance upon, this IEC Publication or any other IEC Publications.
70 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable
71 for the correct application of this publication.
72 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights.
73 IEC shall not be held responsible for identifying any or all such patent rights.
74 International Standard IEC 63286 has been prepared by subcommittee SC34A: Electric light sources, of
75 IEC technical committee 34: Lighting.

195 The requirements according to IEC 62922:2016, 5.2 apply.
196
197 6 Initial photometric and electrical characteristics
198 6.1 General
199 The initial photometric and electrical measurement of the flexible OLED panel shall be conducted with the rated
200 current at the flat configuration, the maximum bent condition and other configurations if declared according to
201 Table 2.
202 The panel shall be supported by a semi-cylinder of each configuration.
203 In case some measurements cannot be conducted in the maximum bent condition, appropriate conditions shall be
204 declared in the data sheet.
205 The initial values of photometric characteristics shall be measured after stabilization of the flexible OLED panel.
206 For operation, stabilization and test conditions of the flexible OLED panel, 4.2 and 4.3 apply.
207 Unless otherwise specified, for general conditions of photometric and colorimetric measurements, CIE S 025:2015
208 and CIE S 025-SP1:2019 apply.
209 An image luminance measurement device (ILMD) is not recommended to measure luminance of flexible OLED
210 panels in convex or concave configurations, as the distance between the ILMD and the flexible OLED panel does
211 not remain the same due to the curvature.
212 Note : For use of ILMD, see CIE 242:2020, 3.
213
214 6.2 Input power
215 The input power test of the flexible OLED panel shall be conducted with the rated DC current or DC voltage.
216 Compliance:
217 For all the tested samples, the measured input power shall not exceed the rated power by more than 10 % after
218 stabilization.

221 For the measurement of the luminous flux of a flexible OLED panel in the flat configuration, IEC
222 62922:2016, 7.2 applies. For the convex or concave configurations, Annex A applies.
223 Compliance:
224 For all the tested samples, the initial luminous flux (flat), the initial luminous flux (convex) and the initial
225 luminous flux (concave) shall not be less than 90 % of their respective rated initial values.
226
227 6.4 Luminous efficacy
228 Flexible OLED panel efficacy shall be calculated from the measured initial luminous flux of the individual OLED
229 panel, divided by the measured initial input power of the same individual flexible OLED panel in each
230 configuration.
