IEC 62715-6-23:2024

Overview

IEC 62715-6-23:2024 is an international standard developed by the International Electrotechnical Commission (IEC) for evaluating the mechanical durability of foldable display modules. This part, titled Flexible display devices – Part 6-23: Mechanical test methods – Mechanical misaligned folding test method, provides standardized test methods that simulate real-world conditions where foldable display devices, such as smartphones, tablets, and laptops, undergo repeated folding and occasional shocks. The standard covers procedures to assess device robustness against misalignment caused by repeated use and impact, ensuring product reliability and quality in practical applications.

Keywords: IEC 62715-6-23:2024, flexible displays, foldable devices, mechanical durability, misaligned folding, mechanical test methods, display robustness, foldable display testing.

Key Topics

• Mechanical Misaligned Folding Testing:
  Defines procedures to simulate real-life stresses on foldable displays, focusing on conditions that represent typical user interactions and accidental impacts.

• Cyclic Folding Test:
  Outlines the method to repetitively fold and unfold display panels, measuring the endurance and identifying the onset of mechanical or visual defects.

• Drop Test (Ball/Pen Drop):
  Describes testing under impact conditions, such as dropping or pressing, to check for damage or misalignment after cyclic folding. The test uses different sized and weighted objects to simulate varying forms of physical shock.

• Test Sample Preparation and Visual Inspection:
  Details methods for preparing test samples and conducting initial visual inspections to establish baseline quality before testing.

• Environmental Test Conditions:
  Specifies standard atmospheric conditions (temperature, humidity, and pressure) under which durability tests are performed to ensure consistency.

• Reporting and Documentation:
  Provides guidance on reporting test parameters and results, essential for meaningful data comparison and product qualification.

Applications

IEC 62715-6-23:2024 delivers practical value for manufacturers, quality assurance teams, and research labs involved in the development and qualification of foldable electronic displays. Key applications include:

• Product Development:
  Supports the design of foldable smartphones, tablets, and laptops by providing robust test methods to evaluate the durability of new materials and hinge mechanisms.
• Quality Assurance and Certification:
  Enables manufacturers to reliably assess product performance under normal and extreme usage scenarios, ensuring customer satisfaction and reducing returns due to mechanical failure.
• Comparative Benchmarking:
  Facilitates transparent comparison among products or design iterations by using consistent, repeatable test methods for mechanical durability.
• Supply Chain Collaboration:
  Establishes a common reference point for manufacturers and suppliers to align on mechanical performance criteria for foldable displays.
