36 INTERNATIONAL ELECTROTECHNICAL COMMISSION
37 ____________
39 FLEXIBLE ORGANIC LIGHT EMITTING DIODE (OLED) PANELS
40 FOR GENERAL LIGHTING — PERFORMANCE REQUIREMENTS
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.
76 The text of this standard is based on the following documents:

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.

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.
