IEC 61747-10-1:2013

Overview

IEC 61747-10-1:2013 is an international standard developed by the International Electrotechnical Commission (IEC) for liquid crystal display (LCD) devices. This standard, part of the broader IEC 61747 series, specifies mechanical test methods to evaluate the reliability, durability, and mechanical robustness of LCD devices, including both cells and modules. By referencing proven methodologies such as those from IEC 60068, it promotes uniformity and consistency in assessing LCD mechanical performance globally.

Key Topics

The standard addresses critical aspects of the mechanical testing of LCD devices, including:

• Mechanical Robustness: Guidance on assessing the durability of LCD terminations, such as wire terminations, pins, connectors, and flexible cables.
• Soldering Tests: Application of standardized tests to evaluate solderability and resistance to soldering heat for devices with leads.
• Vibration Testing: Methods for sinusoidal vibration testing to determine an LCD’s ability to withstand mechanical vibrations during operation or transport.
• Shock and Acceleration: Procedures to test resistance to mechanical shock and steady-state acceleration, ensuring LCDs remain operational after exposure to abrupt forces.
• Bond Strength: Test methods for determining the strength and reliability of bonds, especially in devices using flexible flat cable technology.
• Uniform Test Conditions: Establishes preferred values for temperature, humidity, air pressure, and endurance durations to ensure reliable and repeatable results.

Applications

IEC 61747-10-1:2013 delivers practical value for:

• Manufacturers of LCD devices: Ensures that products meet universally recognized levels of mechanical robustness, supporting international market access.
• Quality Assurance and Reliability Engineering: Enables consistent application of mechanical endurance tests during R&D, production, and pre-shipment stages.
• Component Selection and Procurement: Assists purchasers in specifying LCDs with proven mechanical durability, reducing risk in end applications.
• Certification and Regulatory Compliance: Offers the framework for certifying LCD products in line with global standards, simplifying conformity assessments and audits.
• Product Development: Facilitates comparative evaluation of design improvements, material choices, and assembly techniques related to mechanical integrity.
