25、g methods Image quality: defects and degradation 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 o
26、n 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 P
27、ublication(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 preparatio
28、n. 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
29、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 ma
30、de 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 transp
31、arently 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 provides no marking procedure to indicate its approval and cannot be
32、rendered responsible for any equipment declared to be in conformity with an IEC Publication. 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
33、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 an
34、y 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 b
35、e the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 61988-2-3 has been prepared by IEC technical committee 110: Flat panel display devices. The text of this standard is based on the following documents: FDIS Repo
36、rt on voting 110/180/FDIS 110/188/RVD 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 of all the parts in the IEC 61988 seri

At this date, the publication will be reconfirmed; withdrawn; replaced by a revised edition, or amended. 6 61988-2-3 IEC:2009 PLASMA DISPLAY PANELS Part 2-3: Measuring methods Image quality: defects and degradation 1 Scope This part of IEC 61988 determines the measu
39、ring methods for defects and degradation of colour plasma display (PDP) module in the following areas: a) cell defects; b) image sticking; c) luminance lifetime. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, on
40、ly the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

42、definitions For the purposes of this document, most of the terms and definitions used, comply with IEC 61988-1, IEC 60068-1 and IEC 60107-1, and the followings apply. 3.1 cell defect cell showing a dark defect or a bright defect, or an unstable cell 3.2 defect luminance ratio percentage of luminance
43、 difference from the full screen white-level luminance of each colour 3.3 unstable cell cell that changes luminance in an uncontrollable way 61988-2-3 IEC:2009 7 4 Standard measuring conditions 4.1 Environmental conditions Measurements shall be carried out under the standard environmental conditions
44、, e.g. at a temperature of 25 C 3 C, a relative humidity of 25 % to 85 % and pressure of 86 kPa to 106 kPa. When different environmental conditions are used, it shall be noted on the report. 4.2 Lighting conditions The following dark-room conditions shall be used for all measurements. Illuminance sh
45、all be less than 1 lx anywhere on the screen of the PDP module. When this illuminance significantly affects the measurement of the black level, the background subtraction method shall be used. In case of a different illuminance or if the background subtraction method is used, it shall be noted on th
46、e report. 4.3 Set-up conditions Standard set-up conditions are given below. Each condition shall be noted on the specification form whenever any measurement is carried out under conditions that differ from the standard set-up conditions. 4.3.1 Adjustment of PDP modules For contrast adjustable PDP mo
