Overview
IEC 62629-1-2:2021, developed by the International Electrotechnical Commission (IEC), defines the essential terminology and letter symbols for 3D display devices. As part of the IEC 62629 series, this standard establishes a common language for manufacturers, developers, and users of 3D display technologies, covering areas such as stereoscopic, autostereoscopic, volumetric, and holographic displays.
The 2021 edition includes updates such as new terms relating to holographic and light field displays, expanded definitions for performance specifications, and an annex detailing depth perception in 3D displays. This harmonized terminology enables more accurate communication, specification, and measurement across a rapidly developing field.
Key Topics
- Terminology Definitions: Establishes clear definitions for frequently used terms, such as stereoscopic display, autostereoscopic display, volumetric display, light field display, holographic display, and voxel.
- 3D Display Classifications: Clarifies the differences between types of 3D displays, including classifications covered in the IEC 62629 series.
- Performance Specification Terms: Introduces standardized terms for measuring and comparing display characteristics, such as interocular crosstalk, contrast and luminance differences, and ghosting.
- Component Descriptions: Defines components used in 3D displays, including active glasses, passive glasses, parallax barriers, lenticular lenses, and spatial light modulators.
- Depth Perception: Provides detailed explanations of depth perception cues in 3D displays through a newly added annex, addressing binocular parallax, convergence-accommodation conflict, and distinctions between horizontal-parallax-only and full-parallax 3D displays.
- Guidelines for Use of Key Concepts: Offers additional guidance on using terms like "image," "view," and "vision" to ensure consistency and reduce confusion.
Applications
IEC 62629-1-2:2021 is invaluable in several contexts:
- Product Development: Enables display manufacturers and technology developers to ensure consistent terminology when designing, producing, and marketing new 3D display solutions.
- Testing and Measurement: Serves as a reference for laboratories and quality control professionals to align test reports and measurement results across different 3D display technologies.
- Documentation and Communication: Assists technical writers and professionals in preparing precise, unambiguous documentation, user manuals, and marketing material for 3D display products.
- Research and Education: Provides a foundational vocabulary for academic research, presentations, and teaching materials in the field of 3D imaging technologies.
- Standardization and Compliance: Supports regulatory bodies and conformity assessment organizations in creating or referencing clear, internationally recognized definitions during certification, procurement, or interoperability efforts.
