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.
International Standard IEC 61747-2-2 has been prepared by IEC technical committee 110:
Electronic display devices.
This second edition cancels and replaces the first edition published in 2004. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
1) The new edition was editorially changed to follow the current ISO/IEC Directives, for
example
– added the scope;
– re-arranged the numbering scheme;
– added titles to the tables;
– 4 – IEC 61747-2-2:2014  IEC 2014
– added an Annex A , and put some text from Clause 4 and Clause 10 in it;
– removed IECQ reference;
– deleted some unnecessary text.
2) Several words and test conditions were added in Clause 7 and Clause 8.
The text of this standard is based on the following documents:
CDV Report on voting
110/515A/CDV 110/567A/RVC
Full information on the voting for the approval of 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.
A list of all the parts in the IEC 61747 series, under the general title Liquid crystal display
devices, can be found on the IEC website.
The committee has decided that the contents of this publication will remain unchanged until
the stability date indicated on the IEC website 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.
A bilingual version of this publication may be issued at a later date.

3 Guidance for preparation of a detail specification
The front page layout is illustrated. When the detail specifications for customer circuits are not
published, the layout requirements of the blank detail specification are optional. A suggested
front page layout is also illustrated. An example of a customer detail specification (CDS) is
also given.
The numbers between square brackets on the front page of the blank detail specification
illustrated correspond to the following indications which should be given:
[1] The name of the National Standards Organization or NAI (National Authorised Institution)
under whose authority the detail specification is issued.
[2] The number of the detail specification.
[3] The numbers and issue numbers of the generic and sectional specifications.

– 6 – IEC 61747-2-2:2014  IEC 2014
[4] The national number of the detail specification, date of issue and any further information,
if required by the national system.
[5] Type number(s) of device.
[6] Information on typical construction and applications. If a device is designed to satisfy
several applications, this shall be stated here. Characteristics, limits and inspection
requirements for these applications shall be met. If a device is electrostatic sensitive, or
contains hazardous materials, a caution statement shall be added in the detail
specification.
[7] Outline drawing and/or reference to the relevant document for outlines.
[8] Category of assessment level.
[9] Reference data on the most important properties to permit comparison between types.
