IEC 62341-2-1:2015

Overview

IEC 62341-2-1:2015 defines the essential ratings and characteristics of OLED display modules. It is part of the IEC 62341 series on organic light emitting diode (OLED) displays and sets out the parameters manufacturers and users should specify for OLED modules - including limiting values, electrical and optical characteristics, mechanical outlines and supplementary handling and testing information. The standard guides consistent datasheet content and test-condition description for passive and active matrix OLED modules (monochrome and colour).

Key topics and requirements

• Types and structure: covers passive-matrix monochrome, passive-matrix colour and active-matrix colour OLED display modules; describes panel, circuit and bezel composition.
• Modes of operation: addressing modes (passive, active) and optical modes (top-/bottom-emission, number of colours/grey scales).
• Outline and connections: material/mechanical descriptions, connector types (connectors, flex cables, pins), outline drawings, active area and bezel dimensions.
• Limiting values (absolute maximum ratings): operating and storage temperature and humidity ranges, and supply and input signal voltage limits - specified as required fields for module specifications.
• Electrical characteristics: supply voltages for logic and EL drives, input signal voltage levels, operating and frame frequencies, supply currents and input currents.
• Optical characteristics: luminance, luminance uniformity, dark-room and ambient contrast ratios, viewing angle definitions, chromaticity (white, R/G/B), reflectance, and half-luminance lifetime (T50).
• Performance and reliability items: image sticking, power consumption and lifetime metrics.
• Supplementary information: timing characteristics, voltage sequencing, temperature-dependant operating ranges, handling/ESD precautions, installation and safety guidance, and reflectance characterization.

Applications and who uses it

• OLED module manufacturers use IEC 62341-2-1 to produce consistent datasheets and to define module acceptance criteria.
• Product designers and system integrators (OEMs) reference the standard when selecting modules to ensure compatibility and to specify environmental and electrical requirements.
• Test laboratories and quality assurance teams use the listed characteristics to design measurements and report test results consistently.
• Procurement and compliance engineers rely on the defined parameters when comparing suppliers and validating performance claims.

Practical uses include defining supplier datasheets, specifying test conditions for qualification, and ensuring interoperability between displays and host electronics.
