IEC 62341-6-3:2017

Overview

IEC 62341-6-3:2017 is an international standard developed by the International Electrotechnical Commission (IEC) under the title "Organic Light Emitting Diode (OLED) Displays – Part 6-3: Measuring Methods of Image Quality". This standard establishes uniform measurement conditions and techniques for evaluating the image quality of OLED display panels and modules. By providing a reliable framework for assessing performance parameters, IEC 62341-6-3:2017 supports manufacturers, testing labs, and developers in ensuring consistency and comparability across OLED display products.

This edition, which supersedes the 2012 version, introduces technical updates such as revised methods for viewing angle analysis, added procedures for color characteristic measurement, more detailed discussion on static image resolution, and an annexed method for measuring moving image resolution. The October 2019 corrigendum has also been incorporated to maintain the standard's accuracy and clarity.

Key Topics

IEC 62341-6-3:2017 covers essential metrics and procedures for the objective and reproducible measurement of OLED display image quality, including:

• Standard Measurement Conditions

  • Definition of environmental factors (temperature, humidity, atmospheric pressure)
  • Warm-up protocols and recommended dark-room conditions for consistent measurement

• Measuring Equipment and Set-up

  • Specification of light measuring devices (LMDs), colorimeters, spectroradiometers, and goniophotometric mechanisms
  • Guidelines for display orientation and device under test (DUT) installation

• Viewing Angle Measurement

  • Methodology to quantify viewing angles, including the half luminance angle
  • Assessment of gamma distortion and directional color variation

• Color Characteristics and Accuracy

  • Measurement of chromaticity coordinates and color fidelity
  • Evaluation of color desaturation and color scale range

• Resolution and Spatial Quality

  • Procedures for static image resolution and crosstalk evaluation
  • Contrast and effective resolution under various conditions

• Temporal Image Quality

  • Techniques for assessing flicker and grey-to-grey response times
  • Moving image resolution evaluation (detailed in Annex B)

Applications

IEC 62341-6-3:2017 applies broadly across the OLED display industry wherever precise, standardized image quality assessment is required. Key applications include:

• Product Development and Manufacturing
  • Ensuring OLED display panels meet consistent quality benchmarks during design and production
• Quality Assurance and Testing
  • Facilitating third-party and in-house verification of OLED display image quality
  • Enabling meaningful, comparable test results between different display models or brands
• Procurement and Specification
  • Supporting procurement teams with technical references for OLED display performance
  • Informing technical specifications and contractual requirements in display supply chains
• Research and Innovation
  • Providing a foundation for performance improvement research and new display technology evaluation

Related Standards

To ensure comprehensive OLED display performance evaluation and terminology clarity, IEC 62341-6-3:2017 should be used alongside related standards, including:

• IEC 62341-1-2: Organic light emitting diode (OLED) displays – Terminology and letter symbols
• Other parts of the IEC 62341 series: Address different aspects of OLED displays, such as performance, environmental considerations, and long-term reliability

Summary

Adopting IEC 62341-6-3:2017 for OLED display image quality measurement enables organizations to benchmark and improve product performance, meet industry expectations, and minimize ambiguity in display assessment. This standard is essential for anyone involved in the design, testing, procurement, or research of OLED display technologies, offering authoritative guidelines for accurate, reproducible measurement of critical image quality attributes such as viewing angle, color fidelity, and resolution.
