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

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.

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: 11 ----------------------
– 10 – 61966-5  IEC:2008

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.
