Overview
IEC 62715-6-42:2026 is an International Electrotechnical Commission (IEC) standard that specifies the mechanical test methods for measuring the flattening force of rollable display devices. This document is a crucial part of the IEC 62715 series focused on flexible displays. It defines standardized measurement conditions and methodologies for evaluating the force required to flatten rollable display panels and modules, which are commonly rolled along a single axis or a double axis.
As the adoption of rollable and flexible display technologies expands, accurate and standardized flattening force measurements are vital for device durability, user experience, and overall product quality. This standard ensures consistency across the industry, supporting both development and quality assurance for manufacturers and suppliers.
Key Topics
IEC 62715-6-42:2026 covers several essential aspects relevant to mechanical testing of flexible, rollable displays:
- Flattening Force Definition: Establishes the force required to unfurl a rollable display into a flat state.
- Device Types: Addresses measurement methods for both Type A and Type B rollable display device designs, applicable to one-axis and double-axis configurations.
- Measurement Procedures: Details step-by-step processes and required equipment for conducting flattening force tests, including the use of tension sensors and height measurement systems.
- Environmental Conditions: Specifies standard atmospheric conditions (temperature, humidity, pressure) for consistent and reliable testing.
- Arching Height Measurement: Describes methods for measuring the arching height of display surfaces under tension using laser scanning technology.
- Analysis and Reporting: Outlines required data recording, such as flattening force applied, number of reel turns, arching height, and equipment configuration.
Applications
IEC 62715-6-42:2026 has direct applications in several areas of the flexible display industry, including:
- Research & Development: Supports the creation and refinement of new rollable display technologies by providing objective, consistent measurement results.
- Product Testing & Quality Control: Helps manufacturers and suppliers verify that rollable displays meet required flattening force specifications, ensuring reliable operation over product life cycles.
- Device Reliability Assessment: Enables assessment of long-term mechanical reliability and resilience to repeated rolling and flattening cycles.
- User Experience Optimization: Guides optimization of device design to balance the user experience (minimal arching, easy flattening) with display durability and product safety.
- Supplier Agreements: Facilitates clear specification and acceptance criteria between component suppliers and device manufacturers.
