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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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.
International Standard IEC 61966-5 has been prepared by technical area 2: Colour
measurement and management of IEC technical committee 100: Audio, video and multimedia
systems and equipment.
This second edition cancels and replaces the first edition published in 2000. This edition
includes the following significant technical changes with respect to the previous edition:
Annex A has been deleted as it is no longer relevant.

INTRODUCTION
A series of methods and parameters for colour measurements and management for use in
multimedia systems and equipment is applicable to the assessment of colour production and
reproduction. This part of IEC 61966 deals with equipment using plasma display panels (PDP)
to display colour images for use in multimedia applications.
The methods of measurement standardized in this part of IEC 61966 are designed to make
possible the objective performance assessment and characterization of colour reproduction of
PDP displays which accept red – green – blue analogue or digital signals from electrical input
terminals and output colour images on PDP display screens. For PDP displays to which
analogue signals are applicable, the corresponding digital signals are taken into account. The
measured results are intended to be used for the purpose of equipment specific colour control
in order to enable colour management in open multimedia systems.

1 Scope
This part of IEC 61966 defines input test signals, measurement conditions, methods of
measurement and reporting of the measured data, to be used for colour characterization and
colour management of plasma display panels in multimedia systems.
Colour control within equipment is outside the scope of this International Standard. It does not
specify limiting values for various parameters.

5 Conditions
5.1 Environmental conditions
All measurements specified in this standard shall be carried out in a dark room. Particular
attention should be paid to reflected illumination caused by the ambient objects (desktop,
wall, etc.) and to direct illumination from light-emitting indicators of measuring instruments.
A 1 h warm-up time should precede the measurements in 7.2, 9.2, 10.2, 11.2 and 14.2, if not
specified by the manufacturer of the equipment.
The mains voltage and frequency shall be at the rated values specified by the manufacturer of
a PDP display. When the mains voltage fluctuates, a regulated power supply should be used
to maintain the supply voltage within ±5 % of the rated value.
---------------------- Page: 15 ----------------------
SIST EN 61966-5:2009
– 10 – 61966-5 © IEC:2008(E)
Other environmental conditions such as room temperature and relative humidity shall be
reported together with the results of the measurements.
If additional environmental conditions are described in the manufacturer’s specifications,
these should also be taken into account.
5.2 Conditions of measurements
Contrast, brightness and additional adjustments shall be set to the preset positions specified
by the manufacturer of the PDP display under measurement. When the adjustment is set to a
position other than the preset, the position or corresponding value should be reported with the
results of the measurements.
The equipment arrangement for non-contact measurements should be as shown in figure 1. It
incorporates a spectroradiometer or a non-contact colorimeter, depending on the character-
istics to be measured. The instrument optical axis should be normal to the centre of the
surface of the PDP display.
The distance d between the faceplate of the PDP display and the measuring instrument shall
be 4 h or larger, where h is the effective screen height of the display, see Figure 1.
NOTE 1 It is recommended to take precautions so that the measurement is not influenced by vibration and that
there are no missing picture elements within the field of view of the measuring instrument.
NOTE 2 The measurement area in the colour patch should include more than 500 picture elements.
