Overview
IEC 62629-12-1:2014 specifies standardized optical measuring methods for characterizing the performance of 3D stereoscopic display devices that require glasses, covering both active and passive types. Published by the International Electrotechnical Commission (IEC), this standard addresses key optical measurement practices and conditions needed to independently and objectively assess stereoscopic (3D) display quality when using specialized glasses.
This international standard applies to various categories of stereoscopic displays:
- Displays using active glasses (shutter glasses) for temporally interlaced (high frame rate) images,
- Displays using passive glasses (linear or circular polarizers) for temporally interlaced images with a front screen switchable polarizer,
- Displays with patterned retarders and passive glasses for spatially interlaced images.
Some measurement methods within this standard may be adapted for other types of stereoscopic displays using glasses.
Key Topics
IEC 62629-12-1:2014 focuses on the following core areas:
-
Performance Measurements for 3D Displays with Glasses:
- Luminance and luminance uniformity
- Interocular luminance and contrast differences
- Dark-room contrast ratio
- Colour gamut and chromaticity
- Uniformity, crosstalk, and their position dependencies (e.g., interocular crosstalk uniformity)
- Viewing direction, distance, and angle dependencies
-
Measurement Procedures for 3D Glasses:
- Transmittance and extinction ratio
- Colour shift and chromaticity difference between eyes
- Response time for active glasses (open/closed lens states)
- Angular and temperature dependencies
- Lens uniformity
-
Measurement Conditions and Layouts:
- Standardized measuring equipment
- Measuring setups simulating realistic viewing situations (viewing distance, angle, and environmental conditions)
Applications
IEC 62629-12-1:2014 delivers practical value for manufacturers, quality assurance professionals, engineers, and testing laboratories working with 3D displays and accompanying glasses. Its standardized methods help to:
- Ensure Consistent Quality: By defining clear test procedures, manufacturers can deliver reliable and repeatable data on key optical performance indicators for 3D display devices.
- Facilitate Comparison: Common measurement methods improve comparability between different devices and brands, supporting market transparency.
- Support R&D and Product Development: Engineers and designers can use the standard’s methods to optimize display and glasses parameters for enhanced 3D viewing experiences.
- Assist Testing and Certification: Testing laboratories and certification bodies use the standard as a reference to verify product compliance and performance claims.
Industries and use-cases include:
- Consumer electronics (televisions, monitors)
- Professional visualization (medical imaging, simulation)
- Digital cinema and entertainment
- 3D display research and development
