IEC 61747-10-2:2014

Overview

IEC 61747-10-2:2014 defines environmental and endurance test methods for liquid crystal display (LCD) devices (cells and modules). It establishes uniform preferred test procedures and stress levels to judge environmental performance, aligning where possible with the IEC 60068 environmental testing series. This edition (2014) adds example test conditions and updates references, and replaces parts of the previous IEC 61747-5 edition.

Key topics and technical requirements

• Scope and purpose
  • Standardizes environmental test methods for LCDs to evaluate durability and reliability under defined stress conditions.
  • In case of conflict, a specific relevant specification takes precedence.
• Standard test atmosphere
  • Default measurement conditions: 15 °C to 35 °C, 25 % to 85 % RH (as applicable), air pressure 86–106 kPa, and absolute humidity limits.
• Temperature tests
  • Rapid change (thermal shock) - two‑chamber method (Na): selectable low/high temperatures from defined tables (e.g., −50 °C to +100 °C entries), exposure durations (10 min–3 h), transition times (examples: 2–3 min, 20–30 s,
