Description (English):

IEC 62341-5-3:2019 specifies the standard measuring methods for determining the image sticking and lifetime of organic light emitting diode (OLED) display panels and modules, except finalized display products for end customers, such as TV sets, monitor sets and mobile phones. The measuring method for the lifetime mainly applies to modules. This edition includes the following significant technical changes with respect to the previous edition: a) the measurement vehicle for lifetime is only for the module; b) the measurement method for monitor or TV devices is modified; c) the digital signage display is included as an example of OLED devices; d) the measurement method with HDR (high dynamic range) for image sticking is added; e) the analysis method with CIEDE 2000 is added for image sticking; f) the information method for evaluating image sticking is modified.

Abstract

Overview

IEC 62341-5-3:2019 specifies standard measuring methods for determining image sticking and luminance lifetime of organic light emitting diode (OLED) display panels and modules (excluding finalized consumer products such as TV sets, monitor sets and mobile phones). The second edition updates measurement vehicles and analysis methods and adds procedures for HDR displays and CIEDE2000 colour-difference analysis. The lifetime measurement mainly applies to modules, while modified methods address monitor/TV devices and include digital signage examples.

Key topics and technical requirements

Scope and test objects
- Applies to OLED panels and modules (measurement for finalized products is excluded; monitor/TV measurement methods were updated).
- Lifetime measurement is focused on modules.
Measuring configuration and conditions
- Defines the measuring system arrangement, required light measuring device (LMD) characteristics, and standard environmental/darkroom conditions.
- Standard setup covers DUT adjustments, starting conditions, and equipment calibration.
Image sticking measurement
- Procedures for stress patterns, measuring areas, and post-stress evaluation.
- Includes both SDR and HDR test patterns and procedures to reflect modern content (HDR measurement method added in this edition).
- Analysis options include luminance and colour-difference evaluation using CIEDE2000 (newly introduced).
Luminance lifetime measurement
- Specifies equipment, test procedures and lifetime estimation/extrapolation methods.
- Defines equivalent signal level (digital code 0–255 for 8-bit transforms) and equivalent current density concepts to normalize varying dynamic content - see Annex A for calculation methods.
Reporting and analysis
- Standardized reporting formats for image-sticking metrics, target times, and lifetime thresholds.
- Annex B provides the CIEDE2000 colour-difference calculation procedure.

Practical applications and who uses this standard

Display manufacturers and module developers - for product development, benchmarking and quality control of OLED panels and modules.
Test and certification laboratories - to perform repeatable, internationally consistent image-sticking and lifetime tests.
R&D teams and materials suppliers - to evaluate degradation behaviour under controlled stress and to compare materials/process variants.
System integrators and digital signage vendors - to assess module suitability for continuous/static-content applications where image retention or long-term luminance is critical.

Benefits: consistent, repeatable measurements; valid comparisons across suppliers and designs; guidance for new HDR and colour-difference analysis in image-sticking evaluation.
