27、rnational 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 elec
28、tronic 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 committe
29、es; 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 S
30、tandardization (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 ha
31、s 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 accura
32、te, 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
33、 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 som
34、e 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 i
35、ncluding 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 r
36、eliance 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 th
37、e 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: Flat panel display devices. The text of this standard is bas
38、ed 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 drafted in accordance with the ISO/IEC Directives, Part 2. A list
39、 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 stability date indicated on the IEC web site under “http:/we
40、bstore.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 indicates that it contains colours which are considered to b
41、e 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 part of IEC 61988 determines the measuring methods for charac
42、terizing 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 indispensable for the application of these standards. For standards wit
