Standards Development

Scope

This part of IEC 62629 specifies the standard measurement conditions and measurement methods for determining the optical properties of autostereoscopic displays under the ambient illumination conditions. Standard illumination/measurement geometries are specified and the reflection properties of autostereoscopic displays under those conditions are determined and apply to estimate the photometric and colorimetric characteristics of autostereoscopic displays under reference illumination levels and spectra.

This document applies to two-view/multi-view displays, integral imaging displays. .

Purpose

1.Purpose: This proposal aims to conduct comprehensive optical measurements of the 3D display characteristics under ambient light for stereoscopic displays. Autostereoscopic displays, commonly known as glasses-free 3D displays, have gained significant interest in recent years due to their potential for providing immersive visual experiences without the need for specialized eyewear. As the market for traditional stereoscopic displays with the glasses continues to fade away, autostereoscopic displays have emerged as a promising alternative, finding applications in various fields such as entertainment, medical visualization, and aerospace displays. The primary objective of this research is to advance the understanding of stereoscopic displays' optical performance under ambient light conditions.

2.Justification: Several reasons warrant the need for this research on optical measurement of 3D display characteristics under ambient light, with a particular focus on auto-stereoscopic displays:

a.Growing Interest in Auto-Stereoscopic Displays: With the decline of traditional stereoscopic displays and the increasing demand for immersive visual experiences, auto-stereoscopic displays have emerged as a potential solution. However, limited research has been conducted to evaluate their performance in real-world lighting conditions, where ambient light can significantly impact the perceived 3D effect and overall image quality; how the additional sensory capabilities, for example, contrast perception from the left and right views is effected by the ambient light.

b.Real-World Applicability: For auto-stereoscopic displays to be widely adopted, they must perform consistently well in diverse real-world environments with varying lighting conditions. Evaluating the displays solely under the darkroom laboratory settings may not reflect their actual performance. Moreover, the existing IEC 62977-2-2 is not suitable for 3D display measurement. This research aims to provide a more accurate representation of their behavior in real-world scenarios, making the findings more relevant to industry and end-users.

c.Industry and Market Relevance: The findings from this research will be of significant interest to display manufacturers, as they strive to develop cutting-edge auto-stereoscopic products that meet consumers' demands for superior 3D viewing experiences.

d.Advancements in Measurement Techniques: With advancements in optical measurement technologies, it is now possible to conduct highly accurate and precise assessments of display characteristics under various lighting conditions. This proposal leverages state-of-the-art measurement techniques and equipment to ensure the reliability and credibility.

In conclusion, this proposal seeks to investigate the optical measurement of 3D display characteristics under ambient light, with a specific focus on auto-stereoscopic displays. The purpose is to identify a reliable and repeatable measurement methods to quantify the optical performance of auto-stereoscopic technology. This standard's outcomes will be valuable for both academic research and practical applications in the display industry
