22、 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

23、 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

24、 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

25、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

26、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 misinterpr

27、etation 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

28、 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

29、 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 Commit

30、tees 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

31、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 he

32、ld responsible for identifying any or all such patent rights. International Standard IEC 61747-1-1 was prepared by IEC technical committee 110: Electronic display devices. This Part 1-1 forms the generic specification for liquid crystal display devices. This first edition cancels and replaces the fi

33、rst edition of IEC 61747-1 published in 1998 and Amendment 1:2003. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) IEC 61747-1, has been divided into IEC 61747-1-1, Liquid crystal display device

34、s Part 1- 1: Generic Generic specification and IEC 61747-1-2, Liquid crystal display devices Part 1-2: Generic Terminology and letter symbols; b) the contents of the terminology have been transferred to IEC 61747-1-2; IEC 61747-1-1:2014 IEC 2014 5 c) Annex C has been changed from normative to inform

35、ative, because Tables C.1 and C.2 mismatch some of the large scale production practices of recent date; d) References cited have been updated. The text of this standard is based on the following documents: CDV Report on voting 110/527/CDV 110/563/RVC Full information on the voting for the approval o

36、f 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 web

37、site. NOTE The structure of the IEC 61747 series and the changes in the numbering are shown in Annex D of IEC 61747-30-1:2012. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site under “http:/webstore.iec.ch“ in

38、 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. 6 IEC 61747-1-1:2014 IEC 2014 LIQUID CRYSTAL DISPLAY DEVICES Part 11: Generic
