Overview
IEC 62629-1-2:2013 is an international standard developed by the International Electrotechnical Commission (IEC), focusing on the terminology and letter symbols for 3D display devices. This standard provides a comprehensive glossary of terms frequently used to describe various 3D display technologies within the IEC 62629 series, aiding in the harmonization and clarity of technical communication. It covers terminology relevant to stereoscopic, autostereoscopic, volumetric, and holographic displays, supporting widespread understanding and interoperability in the 3D display technology industry.
Key Topics
- Standardized Terminology: IEC 62629-1-2:2013 includes essential terms and definitions pertaining to the core concepts of 3D display devices. These terms encompass general definitions, component-related terminology, and performance specification terms.
- 3D Display Types:
- Stereoscopic Displays – Provide binocular parallax using viewing aids (e.g., glasses)
- Autostereoscopic Displays – Deliver stereoscopic effect without special viewing aids, in formats such as two-view, multi-view, and integral imaging
- Volumetric and Holographic Displays – Advanced 3D displays, offering depth perception through different technical approaches
- Component Terms: The standard defines key device elements such as active and passive glasses, parallax barriers, lenticular and fly-eye lenses, and display-specific structures (e.g., patterned retarders).
- Performance Specification: Terminology covers interocular luminance, chromatic and contrast differences, interocular crosstalk, designed viewing distance, and 3D crosstalk-parameters essential for evaluating and comparing 3D display performance.
- Clarifications on "Image," "View," and "Vision": The standard provides guidelines and definitions distinguishing between an “image” (as output from a device) and a “view” (as input to the human eye), mitigating potential confusion in technical descriptions.
Applications
- Product Development: Manufacturers use the IEC 62629-1-2:2013 terminology to describe technical specifications and features of 3D display products, from televisions and projectors to head-mounted displays and public signage.
- Testing and Certification: Testing laboratories and quality assurance teams rely on the standardized terms to ensure consistent evaluation methods and reporting of 3D display characteristics.
- Technical Documentation: Engineers and technical writers leverage the glossary to create user manuals, datasheets, and design documentation with unified language, facilitating clear communication across international teams.
- Research and Innovation: Academic and industrial research on next-generation 3D display technology utilize these standard definitions to document findings, publish papers, and collaborate on new developments.
- Regulatory Compliance: Adopting the IEC standardized terminology helps manufacturers demonstrate conformity with international requirements, smoothing market entry and opportunity for global trade.
