Full title and description

Liquid crystal display devices - Part 10-2: Environmental, endurance and mechanical test methods - Environmental and endurance. This IEC International Standard specifies preferred environmental and endurance test methods (with example test conditions and preferred stress levels) for judging the environmental properties of liquid crystal display (LCD) devices, taking into account, wherever possible, the environmental test methods of IEC 60068.

Abstract

IEC 61747-10-2:2014 lists and defines environmental and endurance test methods applicable to LCD devices, provides example test conditions and preferred stress levels, and updates and replaces certain clauses from earlier IEC 61747 documents. The standard is intended to establish uniform test procedures for assessing environmental performance of LCD devices.

Scope

The standard specifies environmental, endurance and related mechanical test methods to be used when assessing liquid crystal display devices. It describes standard atmospheric conditions for measurements and tests, and gives examples of test conditions for environmental stress tests (humidity, temperature cycling, thermal shock, vibration and related endurance tests) while aligning where possible with IEC 60068 environmental test procedures. IEC 61747-10-2 is focused on providing uniform preferred methods and preferred values for stress levels used to judge environmental performance of LCD devices.

Key topics and requirements

• Defined environmental and endurance test methods applicable to LCD devices (temperature, humidity, thermal cycling, thermal shock, salt mist where applicable, etc.).
• Reference to and alignment with IEC 60068 environmental test procedures and terminology.
• Standard atmospheric conditions for measurements and tests.
• Examples of test conditions added to each test method to improve clarity and reproducibility.
• Preferred stress levels and guidance for judging environmental properties of LCD devices.

Typical use and users

Used by LCD manufacturers, component and module suppliers, test laboratories, quality and reliability engineers, and procurement/specification writers to define and perform environmental and endurance testing on LCD devices and modules. Also used by standards committees and product development teams that need consistent test methods for qualification and comparative assessment.

Related standards

IEC 61747-10-2 is part of the IEC 61747 series covering LCD devices and relates to other parts such as IEC 61747-1-1 (generic specification), IEC 61747-2 and 2-2 (module and blank detail specifications), IEC 61747-3 series, and visual inspection parts (for example parts in the 20-x series). It also references IEC 60068 (environmental testing) as a source of environmental test methods.
