Overview
IEC 62341-6-1:2022 is an international standard published by the International Electrotechnical Commission (IEC) that specifies measuring methods for optical and electro-optical parameters of organic light emitting diode (OLED) display modules and, where specified, OLED display panels. The standard defines the procedures and conditions necessary to ensure precise, repeatable measurements, ensuring consistency and comparability across the OLED display industry. This third edition introduces important enhancements, including new measuring methods for power consumption in displays with embedded video connection terminals and updates to video signal content descriptions for power assessments.
Key Topics
-
Standardized Measurement Conditions:
The standard outlines environmental, equipment, and setup requirements for accurate measurement of OLED optical and electro-optical characteristics. All measurements are to be performed under controlled conditions, including measurements in a dark room to limit interference from ambient light.
-
Optical and Electro-Optical Parameter Measurement:
Procedures are provided for assessing characteristics such as luminance, color uniformity, color gamut, contrast ratio, and spectral distribution. The methods apply both to full-color high-resolution modules and lower-resolution or segmented OLED displays.
-
Power Consumption Assessment:
The updated edition includes standardized approaches for measuring the power consumption of displays, particularly those incorporating embedded video connection terminals. It also includes modifications to video signal descriptions relevant to power measurements.
-
Use of Reference Test Patterns:
The standard prescribes the use of specific test patterns to evaluate display performance metrics. These patterns help represent real-world usage scenarios and allow for direct comparison between products.
-
Measurement Locations and Equipment Specifications:
Guidelines are given for measurement positions on the display (e.g., 3×3 grid formation) and requirements for light measuring devices, such as photometers, colorimeters, and spectroradiometers.
Applications
IEC 62341-6-1:2022 is integral for organizations involved in the design, manufacturing, quality control, and certification of OLED display technologies. Key applications include:
-
Product Development and Quality Assurance:
Manufacturers utilize the standard to verify the performance of OLED displays during development and pre-market evaluation, ensuring compliance with global benchmarks.
-
Comparative Performance Testing:
Testing laboratories and third-party certifiers rely on the standardized procedures to conduct impartial performance comparisons, enhancing consumer confidence.
-
Regulatory Compliance:
Following IEC 62341-6-1:2022 supports compliance with regulatory requirements and industry certifications for OLED displays destined for international markets.
-
Technical Documentation:
Engineering teams reference the standard for drafting technical documentation, ensuring internal calibration procedures and reporting align with international best practices.
