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.

4 General statement and test conditions
4.1 General statement

The requirements of this document apply in addition to the requirements of IEC 62868.

The requirement applies for 95 % of the population (with a failure margin below 5 %, it is

considered that the product passed the test).

It is understood that reference to an OLED panel also includes reference to OLED tiles in the

requirements and tests of this document.
4.2 General test conditions

Unless otherwise specified, all measurements shall be made in a draught free room at a

temperature of 25 °C with a tolerance of ±5 °C, a relative humidity of 65 % maximum and

steady state operation of the OLED panel. The temperature shall be maintained within ±2 °C

during the test. The temperature shall be measured in the integrating sphere or at the point

within 1,5 m from the OLED panel.

The tests shall be conducted at the rated current or voltage unless otherwise specified in this

document.

The test shall be made with the OLED panel in the horizontal mounting position with the

surface emitting the largest fraction of luminous flux directed upwards, unless specified

otherwise by the manufacturer. The mounting position shall be recorded in the documentation.

If all surfaces are intended to emit the same luminous flux, the orientation is at the discretion

of the test laboratory. The operating position shall be maintained during the entire test.

In the case of constant current operation: The test current, unless otherwise specified, shall

be stable within ±0,5 % during the performance test of an OLED panel. The total harmonic

content of the input shall not exceed 3 %.

In the case of constant voltage operation: The test voltage, unless otherwise specified, shall

be stable within ±0,05 % or 5 mV whichever is greater during the performance test of an

OLED panel. The total harmonic content of the input shall not exceed 3 %. The tolerance of

±0,05 % is applicable for DC supplies only. The tolerance for AC supplies is under

consideration. The test voltage shall be measured at the terminals of the OLED panel.

---------------------- Page: 13 ----------------------
SIST EN 62922:2017
– 8 – IEC 62922:2016 © IEC 2016
The OLED panel shall be mounted in such a way that thermal contact between the

measurement equipment, sample holder and OLED panel is minimal. During stabilization and

measurement, an OLED panel shall only be in contact with the measurement equipment near

its edges and contact ledges. All other parts of the panel, especially the light output surface

and the opposing surface (the back of the OLED panel) shall be open to air, unless otherwise

specified by the manufacturer.

NOTE The harmonic content is understood as the r. m. s. summation of the individual harmonic components using

the fundamental as 100 %.
4.3 Stabilization
4.3.1 General requirements for stabilization

Stabilization is conducted in a draught free room at a temperature of 25 °C ± 5 °C. The

temperature shall be maintained within ±2 °C during stabilization. The temperature shall be

measured in the integrating sphere or the point within 1,5 m from the OLED panel.

If stabilization conditions, according to 4.3.2 or 4.3.3, are not achieved within 60 min, the

measurement may be started and the observed fluctuations shall be reported.
4.3.2 Current-driven stabilization

This method of stabilization is used for OLED panels intended to be operated primarily in

constant current mode and OLED panels for which the selection of the operating mode is left

to the customer.

The OLED panel shall be powered with a constant input current stable within ±0,5 %.

During the stabilization period, measurements of the voltage are made at least at 1 min

intervals. The OLED panel under test may be regarded as stable and suitable for test

purposes if the difference of maximum and minimum readout voltage observed over the last

5 min is less than 0,5 %.
4.3.3 Voltage-driven stabilization

This method of stabilization is used for OLED panels intended to be operated primarily in

constant voltage mode.

The OLED panel shall be powered with a constant input voltage stable within ±0,05 %.

During the stabilization period, measurements of the current are made at least at 1 min

intervals. The OLED panel under test may be regarded as stable and suitable for test

purposes if the difference of maximum and minimum readout current observed over the last

5 min is less than 1 %.
5 Marking

panel is made, unless the connection method is obvious. This information shall include, as

applicable, information on:
