IEC 61747-6-3:2011

Liquid crystal display devices - Part 6-3: Measuring methods for liquid crystal display modules - Motion artifact measurement of active matrix liquid crystal display modules

IEC 61747-6-3:2011 applies to transmissive type active matrix liquid crystal displays. This standard defines general procedures for quality assessment related to the motion performance of LCDs. It defines artifacts in the motion contents and methods for motion artifact measurement. NOTE: Motion blur measurement methods and analysis methods introduced in this standard could not be universal tools for all different LCD motion enhancement technologies due to its complexity. Users shall be notified of these circumstances.

Dispositifs d'affichage à cristaux liquides - Partie 6-3: Méthodes de mesure pour les modules d'affichage à cristaux liquides - Mesure de l'artefact de mouvement dans les modules d'affichage à cristaux liquides à matrice active

La CEI 61747-6-3:2011 s'applique aux afficheurs à cristaux liquides à matrice active de type transmissifs. Cette norme définit les procédures générales pour l'évaluation de la qualité en ce qui concerne les performances du mouvement des afficheurs LCD. Elle définit les artefacts dans les contenus en mouvement et les méthodes de mesure de l'artefact de mouvement. NOTE: Les méthodes de mesure du flou de mouvement et les méthodes d'analyse introduites dans la présente norme ne sauraient être des outils universels pour toutes les différentes technologies de mesure de l'amélioration du mouvement LCD en raison de sa complexité. Les utilisateurs doivent être informés de ces circonstances.

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
