Overview
ISO/TR 9241-309:2008 - Ergonomics of human-system interaction: Organic light-emitting diode (OLED) displays is a Technical Report that introduces OLED display technology and provides guidance for the ergonomic assessment of OLED-based visual displays. Published as part of the ISO 9241 family, this report is informative (not normative) and recommends assessment approaches where specific OLED test methods are not yet standardized.
Key Topics
- OLED technology overview
- Structure of AM‑OLED panels (substrate, organic layers, electrodes).
- Emission types: bottom‑emission vs top‑emission.
- Basic driving circuits (TFT switching, line scanning, memory capacitor).
- Perceptual and optical properties
- High colour gamut potential (chromaticity characteristics).
- Fast response time (typically < 1 ms) leading to improved motion picture quality and reduced motion blur.
- Isotropic optical behaviour across viewing angles (luminance deviation ≤ ~12% up to 40° in reported measurements).
- Assessment guidance & metrology
- Recommends using existing measurement and compliance routes (notably ISO 9241-307 methods for PDP indoor use) as a practical basis for OLED assessment.
- Specific attributes to consider: design viewing distance, pixel faults, luminance, contrast ratios, luminance non‑uniformity, colour non‑uniformity and reflectance.
- Example measurement values given (typical luminance ~200 cd/m²; darkroom contrast > 1000:1; contrast under 600 lx > 50:1).
- Intended contexts of use
- Indoor viewing conditions (design illuminance up to 600 lx), handheld and stationary devices, full‑colour graphics and realistic scene reproduction.
Applications and Who Uses It
ISO/TR 9241-309:2008 is useful for:
- Display engineers and OLED manufacturers - to align product design and metrology with ergonomic considerations.
- Usability and human factors specialists - to evaluate visual comfort, viewing distances, and perceptual performance.
- Test laboratories and quality assurance - to adapt existing ISO 9241-307 test routes for OLED products.
- Product designers, procurement and compliance teams - for specifying ergonomic display requirements in consumer electronics, mobile devices, automotive clusters, medical displays and professional monitors.
Related Standards
- ISO 9241 series (Ergonomics of human‑system interaction) - especially parts in the “300” subseries:
- ISO 9241-307 - Analysis and compliance test methods for electronic visual displays (referenced as a compliance route for OLED).
- ISO 9241-302, -303, -304, -305, -306 - other visual display terminology, requirements and test methods referenced by the series.
ISO/TR 9241-309:2008 provides practical, ergonomics-focused guidance to assess OLED display performance and to adapt existing visual display test methods for emerging emissive technologies.
