Full title and description

St IEC 62899-502-1-2017 — Printed electronics — Part 502-1: Quality assessment — Organic light emitting diode (OLED) elements — Mechanical stress testing of OLED elements formed on flexible substrates. This International Standard specifies quality assessment methods, with emphasis on mechanical stress test methods for reliability evaluation of flexible OLED elements produced using printed electronics techniques; it excludes OLED products intended for lighting purposes.

Abstract

This standard defines mechanical stress test procedures and related quality-assessment guidance for flexible OLED elements fabricated on flexible substrates by printed-electronics processes. It aims to provide repeatable methods to evaluate mechanical durability (for example bending, rolling, folding, torsion and related stresses) and to support comparability of reliability data for flexible OLED devices (excluding lighting applications).

Scope

IEC 62899-502-1:2017 applies to OLED elements formed on flexible substrates by printed-electronics technology and specifies mechanical stress test methods and quality-assessment procedures for reliability evaluation. The standard is intended for flexible OLED elements (display/indicator applications) and explicitly excludes OLED products intended primarily for lighting. Test types referenced or used in practice to exercise the scope include bending, folding, rolling, torsion and tension tests commonly applied to flexible electronic devices.

Key topics and requirements

• Definition of the applicability domain: flexible OLED elements on flexible substrates produced by printed electronics.
• Mechanical stress test methods for reliability assessment (bending, folding, rolling, torsion, tension as relevant to flexible substrates).
• General guidance on sample preparation and test conditions to enable reproducible mechanical testing.
• Evaluation and recording of failure modes and degradation after specified stress regimes (cycles, radii, speeds where applicable).
• Recommendations for reporting results to support comparison between laboratories and manufacturers.

Typical use and users

Primary users are manufacturers and designers of flexible OLED displays and elements, independent test laboratories and qualification engineers working on printed-electronics devices, reliability engineers developing durability test programs, and national bodies adopting IEC series requirements into regional/national standards. Test-equipment vendors and R&D groups developing printed OLED processes also use the standard to align mechanical stress testing.
