CEI EN 62341-5-2

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.
