Overview

IEC TR 62715-6-21:2022 is an International Electrotechnical Commission (IEC) technical report that addresses the mechanical durability of foldable display devices. Specifically, this report provides detailed information about various folding methods and hinge structures in foldable products, which play a critical role in the durability and reliability of foldable display panels. It focuses on aspects that directly affect the longevity and mechanical performance of the display component, excluding unrelated parts such as speakers, batteries, or communication ports. As flexible and foldable display technology is increasingly adopted in consumer electronics, this guidance is vital for manufacturers, testers, and quality control professionals.

Key Topics

Folding Types: The report categorizes foldable products based on folding method:

In-folding: The light-emitting surface folds inward, protecting the display but increasing folding stress due to a smaller radius of curvature (R value).
Out-folding: The light-emitting surface folds outward, making the display more vulnerable but experiencing less folding stress.
Multi-folding: Panels that fold at multiple points (e.g., "Z-type" in-out folding or "G-type" in-in folding), anticipated for future product generations.
In and out-folding: Products designed to fold both inward and outward, providing greater flexibility.

Hinge Structures: Comprehensive analysis of hinge designs and their impact on durability:

Constant R type: Maintains a relatively consistent radius of curvature during folding.
Varying R type: Features a changing radius for improved stress distribution and reduced crease formation.
The hinge structure influences product thickness, weight, folding angle, and the unfolding experience.

Durability Testing: Guidance on key parameters influencing mechanical durability:

Angle of folding and unfolding: Consistent maintenance of folding angles (typically 0°–180°, potentially up to 360° for advanced designs) is crucial.
Radius of curvature (R value): Consistent R value ensures reliable durability testing.
Folding angular speed: Speed and intervals of folding directly affect applied mechanical stress and are standardized in durability assessments.

Applications

Consumer Electronics: Manufacturers of foldable smartphones, tablets, and laptops benefit from standardized test methods, ensuring product reliability during real-world handling.

Product Design and Development: Engineers and designers use this report to optimize hinge structures and folding mechanisms, reducing failure rates and improving user experience.

Quality Assurance and Testing: Testing laboratories apply the durability test methods detailed in this report to validate the mechanical integrity of foldable display panels.

Innovation and Future Products: By classifying future folding types (multi-folding and bi-directional folding), the standard supports the development of novel flexible display devices.
