IEC 61747-2-1:2013

Overview

IEC 61747-2-1:2013 is an international standard published by the International Electrotechnical Commission (IEC) that defines a Blank Detail Specification (BDS) for passive matrix monochrome liquid crystal display (LCD) modules. This standard is part 2-1 of the IEC 61747 series focused on liquid crystal display devices and provides the framework for creating detailed specifications used in high-quality approval and certification systems.

The 2013 edition is a technical revision that replaces the first edition from 1998, incorporating updated test conditions, editorial changes aligned with ISO/IEC Directives, and clarifications to improve usability. It establishes the style, layout, and minimum content requirements for detail specifications of passive matrix monochrome LCD modules, which are important for manufacturers, testers, and suppliers aiming for consistent product quality and reliability.

Key Topics

• Scope and Purpose: Defines requirements for a blank detail specification serving as a template for product-specific detail documents targeting passive matrix monochrome LCD modules.

• Specification Layout: Specifies the standardized front page layout including:

  • National Standards Organization details
  • IECQ number and issue date
  • Product type numbers and construction info
  • Outline drawings and electrical specifications
  • Category of assessment quality and reference data for comparison

• Marking Requirements: Information to be marked on LCD devices ensuring traceability and conformance.

• Ordering Information: Minimum order details such as precise type reference, IECQ reference number with issue date, quality category, and screening information.

• Limiting Values and Operating Conditions: Defines absolute maximum ratings and recommended operational parameters for electrical and optical characteristics, ensuring safe device operation within specified environments.

• Test Conditions and Qualification: Provides standardized test protocols and inspection requirements to qualify product batches, including lot-by-lot and periodic tests.

• Normative References: Refers to related IEC standards essential for applying this specification, e.g., IEC 61747-1:2003 for generic specifications and IEC 61747-5:1998 for environmental and mechanical tests.

Applications

IEC 61747-2-1:2013 is vital for manufacturers and quality assurance teams involved in the design, production, and certification of passive matrix monochrome LCD modules. Its applications include:

• Product Development: Ensuring new monochrome LCD modules meet internationally recognized criteria before market release.

• Quality Control: Establishing standardized inspection, testing, and approval workflows to maintain product consistency and reliability.

• Procurement and Compliance: Helping buyers specify and order LCD modules that comply with globally accepted standards, facilitating international trade.

• Certification Bodies: Providing a consistent framework for evaluating products against IEC quality levels and issuing certification.

• OEM Integration: Assisting original equipment manufacturers to select compliant passive matrix LCD modules for consumer electronics, industrial equipment, and automotive displays.

Related Standards

• IEC 61747-1:2003 – Generic Specification for liquid crystal and solid-state display devices: Provides foundational guidelines integrated into the 2-1 part for common terms, test methods, and quality categories.

• IEC 61747-2:1998 – Sectional Specification for LCD modules: Complements this part by addressing sectional details relevant to LCD module design and testing.

• IEC 61747-5:1998 – Environmental, Endurance, and Mechanical Test Methods: Specifies durability and environmental test procedures that are referenced for qualification approval.

Summary

IEC 61747-2-1:2013 offers a structured and internationally accepted blank detail specification template tailored specifically for passive matrix monochrome LCD modules. By standardizing layout, content, and testing protocols, it supports manufacturers and stakeholders in achieving high-quality production standards, facilitating clearer communication, easier market acceptance, and improved product reliability in the field of liquid crystal display technology.
