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 61747-3 has been prepared by IEC technical committee 110: Flat
panel display devices.
This second edition cancels and replaces the first edition, published in 1998, and constitutes
a technical revision.
The main changes with regard to the previous edition concern editorial updating in
accordance with current ISO/IEC directives.
This part of IEC 61747 is a sectional specification for liquid crystal display cells. It should be
read together with the generic specification to which it refers.
61747-3 IEC:2006 – 7 –
The text of this standard is based on the following documents:
FDIS Report on voting
110/82/FDIS 110/89/RVD
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.
The QC number that appears on the front cover of this publication is the specification number
in the IECQ Quality Assessment System for Electronic Components (IECQ).
Future standards in this series will carry the new general title as cited above. Titles of existing
standards in this series will be updated at the time of the next edition.
IEC 61747 consists of the following parts, under the general title Liquid crystal display devices:
Part 1: Generic specification;
Part 2: Liquid crystal display modules – Sectional specification
Part 2-1: Passive matrix monochrome LCD modules – Blank detail specification
Part 2-2: Matrix colour LCD modules – Blank detail specification
Part 3: Liquid crystal display (LCD) cells – Sectional specification
Part 3-1: Liquid crystal display (LCD) cells – Blank detail specification
Part 4: Liquid crystal display modules and cells – Essential ratings and characteristics
Part 4-1: Matrix colour LCD modules – Essential ratings and characteristics
Part 5: Environmental, endurance and mechanical test methods
Part 6: Measuring methods for liquid crystal modules – Transmissive type
The committee has decided that the contents of this publication will remain unchanged
