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 61988-4 has been prepared by IEC technical committee 110: Flat
panel display devices.
The text of this standard is based on the following documents:
FDIS Report on voting
110/107/FDIS 110/110/RVD

Full information on the voting for the approval on this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.

can be found on the IEC website.
The committee has decided that the contents of this publication will remain unchanged until
the maintenance result date indicated on the IEC web site under "http://webstore.iec.ch" in
the data related to the specific publication. At this date, the publication will be
• reconfirmed;
• withdrawn;
• replaced by a revised edition, or
• amended.

3 Terms, definitions and letter symbols
For the purposes of this document, most of the definitions used in this standard comply with
IEC 60068-1 and IEC 61988-1. The following symbols are used in addition to those defined in
IEC 61988-1.

air pressure at which the PDP module is operated during the tests
3.2
P
st
air pressure at which the PDP module is stored in a non-operating state during the tests
4 Structure of testing equipment
The system diagrams and/or driving conditions of the testing equipment shall comply with the
structure specified in each item.
5 Standard conditions
5.1 Standard reference atmosphere
Temperature: 25 °C
Air pressure: 101,3 kPa
NOTE No requirement for relative humidity is given because correction by calculation is generally not possible.
If the parameters to be measured depend on temperature and/or pressure and the law of
dependence is known, the values shall be measured in the conditions specified in 5.3 and,
if necessary, be corrected by calculation to the standard reference atmospheric conditions
above.
5.2 Standard atmospheric conditions for reference measurements and tests
If the parameters to be measured depend on temperature, pressure and humidity and the law
of dependence is unknown, the atmospheric conditions to be specified shall be selected from
the following values, as shown in Table 1.
