Liquid crystal display devices - Part 10-1: Environmental, endurance and mechanical test methods – Mechanical

IEC 61747-10-1:2013 lists test methods applicable to liquid crystal display devices. It takes into account, wherever possible, the mechanical robustness test methods as outlined in IEC 60068. The object of this standard is to establish uniform preferred test methods with preferred values for stress levels for judging the mechanical properties of liquid crystal display devices. This first edition of IEC 61747-10-1 cancels and replaces Clauses 1 and 2 of the first edition of IEC 61747-5 published in 1998. This edition constitutes a technical revision.

La CEI 61747-10-1:2013 répertorie les méthodes d'essais applicables aux dispositifs d'affichage à cristaux liquides. Elle prend en compte, dans la mesure du possible, les méthodes d'essais de robustesse mécanique telles qu'elles sont indiquées dans la CEI 60068. L'objet de la présente norme est d'établir des méthodes d'essais préférentielles uniformes indiquant des valeurs préférentielles pour les niveaux de contraintes, permettant d'estimer les propriétés mécaniques des dispositifs d'affichage à cristaux liquides. Cette première édition de la CEI 61747-10-1 annule et remplace les Articles 1 et 2 de la première édition de la CEI 61747-5 parue en 1998. Cette édition constitue une révision technique.

Prikazovalniki s tekočimi kristali - 10-1. del: Mehanske preskusne metode

Overview

EN 61747-10-1:2013 (IEC 61747-10-1:2013) defines mechanical test methods for liquid crystal display devices (cells and modules). Its objective is to establish uniform, preferred test procedures and stress-level values for judging the mechanical robustness and endurance of LCDs. Where possible, it adopts and references mechanical test methods from the IEC 60068 environmental testing series. This edition replaces Clauses 1 and 2 of EN 61747-5:1998 and constitutes a technical revision within the IEC 61747 series.

Key topics and requirements

• Scope and purpose: Provides standard mechanical test methods for LCD devices to enable consistent qualification and comparison.
• Standard atmospheric conditions for measurements and tests:
  • Temperature: 15 °C to 35 °C
  • Relative humidity: 25 % to 85 % RH
  • Air pressure: 86 kPa to 106 kPa
  • Absolute humidity: ≤ 22 g/m³
• Mechanical test methods covered (high-level):
  • Robustness of terminations (wire terminations, pins, flexible terminations)
  • Solderability and resistance to soldering heat
  • Vibration testing (sinusoidal, Test Fc) - frequency ranges, amplitudes, severities and duration guidance; includes transverse motion and distortion considerations
  • Shock testing (impulse/shock conditions and acceptance criteria)
  • Steady-state acceleration testing
  • Bond strength tests - preconditioning, initial measurements, test setup and data to be recorded
• Supplementary content: The standard includes tables for frequency ranges, recommended vibration amplitudes, shock and acceleration conditions, and illustrative figures (e.g., bond strength test examples).
• Normative precedence: In case of conflict between this standard and a device-specific specification, the device specification takes precedence.

Applications and who uses it

EN 61747-10-1 is used by:

• LCD manufacturers for design validation, qualification and production testing
• Test laboratories performing standardized mechanical and reliability tests
• Quality assurance and reliability engineers for establishing acceptance criteria
• R&D teams evaluating mechanical robustness during product development
• Procurement and compliance teams for supplier qualification and contract specifications

Practical uses include vibration and shock qualification for portable and automotive displays, verification of solder and termination robustness for module assembly, and bond strength assessment for long-term reliability.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accur
