Organic light emitting diode (OLED) displays - Part 5-2: Mechanical endurance test methods
This part of IEC 62341 defines testing methods for evaluating mechanical endurance quality of Organic Light Emitting Diode (OLED) display panels and modules or their packaged form for transportation. It takes into account, wherever possible, the environmental testing methods outlined in specific parts of IEC 60068. The object of this standard is to establish uniform preferred test methods for judging the mechanical endurance properties of OLED display devices. There are generally two categories of mechanical endurance tests: those relating to the product usage environment and those relating to the transportation environment in packaged form. Vibration, shock, quasistatic strength, four-point bending test and peel strength test are introduced here for usage environment, while transportation drop test is applicable to the transportation environment. Mechanical endurance tests may also be categorized into mobile application, notebook computer or monitor application and large size TV application. Special considerations or limitations of test methods according to the size or application of the specimen will be noted.

Afficheurs à diodes électroluminescentes organiques (OLED) - Partie 5-2: Méthodes d’essais d'endurance mécanique
La CEI 62341-5-2:2013 définit des méthodes d'essais pour évaluer la qualité de l'endurance mécanique de modules et de panneaux d'affichage à diodes électroluminescentes organiques (OLED) ou de leur emballage d'expédition. Elle tient compte, dans la mesure du possible, des méthodes d'essais d'environnement indiquées dans des parties spécifiques de la CEI 60068. La présente norme a pour objet d'établir des méthodes d'essais préférentielles uniformes pour juger les propriétés d'endurance mécanique des dispositifs d'affichage OLED.
Prikazovalniki z organskimi svetlečimi diodami (OLED) - 5-2. del: Metode za preskušanje mehanske zdržljivosti (IEC 62341-5-2:2013)
Ta del standarda IEC 62341 določa metode za preskušanje kakovosti mehanske vzdržljivosti plošč in modulov prikazovalnikov z organskimi svetlečimi diodami (OLED) ali transportne embalaže le-teh. Kadar je to mogoče, upošteva metode okoljskega preskušanja, kot je navedeno v določenih delih standarda IEC 60068. Cilj tega standarda je vzpostaviti enotne priporočene preskusne metode za ocenjevanje lastnosti mehanske vzdržljivosti prikazovalnikov z organskimi svetlečimi diodami (OLED). Običajno obstajata dve kategoriji preskusov mehanske vzdržljivosti: tista, ki se nanaša na okolje uporabe izdelka, in tista, ki se nanaša na transportno okolje izdelka v pakirani obliki. Vibracije, udarci, kvazistatična moč, štiritočkovni upogibni preskus in preskus odpornosti proti luščenju so tukaj določene za okolje uporabe, medtem ko se za transportno okolje uporablja preskus s padcem med transportom. Preskusi mehanske vzdržljivosti se lahko razvrstijo tudi tako: preskusi za mobilne telefone, prenosne računalnike ali monitorje in velike televizorje. Upoštevajo se posebne zahteve ali omejitve metod za preskušanje glede na velikost ali uporabo preskusnega vzorca.

Part 5-2: Mechanical endurance testing methods
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 of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 62341-5-2 has been prepared by IEC technical committee 110: Electronic display devices. The text of this standard is based on the following documents: FDIS Report on voting 110/472/FDIS 110/486/RVD

1 Scope This part of IEC 62341 defines testing methods for evaluating mechanical endurance quality of Organic Light Emitting Diode (OLED) display panels and modules or their packaged form for transportation. It takes into account, wherever possible, the environmental testing methods outlined in specific parts of IEC 60068. The object of this standard is to establish uniform preferred test methods for judging the mechanical endurance properties of OLED display devices. There are generally two categories of mechanical endurance tests: those relating to the product usage environment and those relating to the transportation environment in packaged form. Vibration, shock, quasistatic strength, four-point bending test and peel strength test are introduced here for usage environment, while transportation drop test is applicable to the transportation environment. Mechanical endurance tests may also be categorized into mobile application, notebook computer or monitor application and large size TV application. Special considerations or limitations of test methods according to the size or application of the specimen will be noted. NOTE This standard is established separately from IEC 61747-5-3, because the technology of organic light emitting diodes is considerably different from that of liquid crystal devices in such matters as: – used materials and structure; – operation principles; – measuring methods. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
