Foreword
The text of document 110/349/CDV, future edition 2 of IEC 61747-4, prepared by IEC/TC 110 "Electronic
display devices" was submitted to the IEC-CENELEC parallel vote and approved by CENELEC as
EN 61747-4:2012.

The following dates are fixed:
(dop) 2013-07-31
• latest date by which the document has
to be implemented at national level by
publication of an identical national
standard or by endorsement
• latest date by which the national (dow) 2015-10-31
standards conflicting with the
document have to be withdrawn

This document supersedes EN 61747-4:1998.
EN 61747-4:2012 includes the following significant technical changes with respect to EN 61747-4:1998:
– 2.1 and 3.1 of EN 61747-4:1998 were deleted because these items are defined in EN 61747-1;
– 2.7.6, in 2.7, Supplementary information, of EN 61747-4:1998 was deleted because the scope of this
standard is about passive matrix monochrome liquid crystal display modules;
– the item “Gray scale: digital or analog” in 2.3.1 of EN 61747-4:1998 was changed to “Gray scale:
number” because it is more accurate;
– contrast mode: light symbol on dark background (“LOD” or “positive image”) or dark symbol on light
background (“DOL” or “negative image”) was introduced in this part of EN 61747 to replace the
description in 2.3.1 and 3.3.1 of EN 61747-4:1998.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CENELEC [and/or CEN] shall not be held responsible for identifying any or all such patent
rights.

Endorsement notice
The text of the International Standard IEC 61747-4:2012 was approved by CENELEC as a European
Standard without any modification.

Essential ratings and characteristics

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
...
