28、 methods Visual quality: Image artifacts 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 qu

29、estions 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 Publicati

30、on(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 co

31、llaborates 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 opinio

32、n 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 ens

33、ure 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 t

34、o 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 certificati

35、on 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 att

36、ach 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 fee

37、s) 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 publicati

38、on. 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 61988-2-4 has been prepared by IEC technical committee 110:

39、Flat panel display devices. The text of this standard is based on the following documents: FDIS Report on voting 110/260/CDV 110/297/RVC Full information on the voting for the approval on this standard can be found in the report on voting indicated in the above table. This publication has been draft

40、ed in accordance with the ISO/IEC Directives, Part 2. A list of all the parts in the IEC 61988 series, under the general title Plasma display panels, can be found on the IEC website. 61988-2-4 IEC:2011 5 The committee has decided that the contents of this publication will remain unchanged until the

41、stability date indicated on the IEC web site 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. IMPORTANT The colour inside logo on the cover page of this publication

42、indicates that it contains colours which are considered to be useful for the correct understanding of its contents. Users should therefore print this document using a colour printer. 6 61988-2-4 IEC:2011 PLASMA DISPLAY PANELS Part 2-4: Measuring methods Visual quality: Image artifacts 1 Scope This p

43、art of IEC 61988 determines the measuring methods for characterizing the performance of plasma display panel (PDP) modules in the following areas: a) viewing angle; b) image streaking; c) flicker; d) moving picture resolution. 2 Normative references The following referenced documents are indispensab
