Flexible displays - Part 6-22: Mechanical test methods - Crease and waviness measurement methods for foldable displays

This document establishes a specific methodology for evaluating the mechanical performance of flexible display panels, with a particular focus on the assessment of creases and wave height in foldable configurations. It outlines the procedural steps required to measure surface irregularities that occur when such devices undergo repeated bending cycles. The standard defines the necessary equipment, test conditions, and measurement techniques to ensure consistency and reproducibility across different laboratories and manufacturers. By providing a unified approach, it facilitates the comparison of results regarding the durability and structural integrity of the display surface after folding operations. This technical specification is intended to support the development and quality assurance processes for flexible electronic components, ensuring that manufacturers can reliably quantify the extent of deformation and surface roughness. It serves as a reference for testing the physical limits and mechanical resilience of advanced display technologies without mandating specific performance thresholds for acceptance.
