IEC 62715-6-2:2017

Overview

IEC 62715-6-2:2017 is an international standard published by the International Electrotechnical Commission (IEC) that sets forth testing methods for evaluating the environmental endurance of flexible display panels and modules. This standard is crucial for manufacturers and stakeholders involved in the design, production, and quality assurance of flexible display devices, such as liquid crystal displays (LCDs), electronic paper displays (EPDs), and organic light emitting diode (OLED) displays. The scope includes requirements for testing under various storage, use, and transport environments to ensure product performance and longevity.

Key Topics

• Environmental Testing Methods: The standard outlines comprehensive procedures for subjecting flexible display panels and modules to various environmental stress tests, including temperature extremes, humidity, and temperature cycling.
• Applicability: Covers a wide range of flexible display technologies including LCDs, EPDs, OLEDs, and mechanically operable panels or modules.
• Test Conditions: Specifies standard atmospheric conditions for reference measurements, operational tests, and recovery periods.
• Measurement and Analysis: Includes guidance for visual inspection, optical performance, and image quality assessment following environmental testing.
• Cyclic Bending and Mechanical Testing: Emphasizes the necessity of mechanical cycling tests prior to environmental testing to simulate real-world usage.
• Standardized Reporting: Details the requirement to document the specific conditions and durations of each environmental test for uniformity and traceability.

Applications
