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: ?C used materials and structure; ?C operation principles; ?C measuring methods.
