Overview
IEC 62341-1-1:2009 is an international standard developed by the International Electrotechnical Commission (IEC) that defines generic specifications for Organic Light Emitting Diode (OLED) displays. This standard provides a comprehensive framework for quality assessment procedures within the IEC Quality Assessment System for Electronic Components (IECQ). It establishes general rules regarding electrical and optical measurement methods, environmental and mechanical testing, and endurance evaluations for OLED display devices.
Aimed at manufacturers, testers, and quality assurance professionals involved in OLED display production and evaluation, IEC 62341-1-1 ensures consistent product reliability and performance across the industry by standardizing measurement and testing processes.
Key Topics
-
Quality Assessment Procedures
The standard details robust quality assessment methods including qualification approvals, commercial confidentiality aspects, inspection lot formation, and subcontracting protocols. It emphasizes stringent quality conformance inspections and outlines statistical sampling plans such as Acceptable Quality Level (AQL) and Lot Tolerance Percentage Defective (LTPD).
-
Measurement Standards
IEC 62341-1-1 specifies standard atmospheric and environmental conditions for testing to ensure repeatable and accurate results. It covers electrical and optical measurement techniques, including visual examination and physical assessments like dimensions and weight.
-
Test Methods
The document details various test procedures:
- Environmental tests simulating real-world operating conditions
- Mechanical tests for durability assessment
- Endurance tests to evaluate long-term device reliability, featuring both general and accelerated test protocols.
-
Marking and Traceability
The standard requires clear device identification markings and traceability coding to link devices back to production or inspection lots, supporting effective quality tracking and recall management.
-
Order of Precedence
It defines a hierarchy for resolving conflicting requirements among related documents, prioritizing detail specifications over generic ones, and including IECQ rules, family specifications, and national standards.
Applications
-
OLED Display Manufacturing
Implementing IEC 62341-1-1 helps manufacturers standardize quality control processes, ensuring OLED displays meet international performance and reliability expectations.
-
