Overview
IEC 62629-22-1:2013 - "3D display devices - Part 22-1: Measuring methods for autostereoscopic displays - Optical" specifies optical measurement methods for autostereoscopic (glasses-free) 3D displays. The standard defines general procedures to evaluate optical characteristics of two‑view and multi‑view autostereoscopic displays and integral imaging displays, providing a consistent framework for lab testing, quality control and product comparison.
Key Topics
The standard focuses on optical metrology for autostereoscopic systems. Key topics and requirements (high level) include:
- Measurement scope and setup
- Defined test geometries, observer/viewpoint positions and measurement distances to capture autostereoscopic behavior.
- Optical characteristics to evaluate
- Viewing zones / angular distribution - mapping where 3D effect and image separation occur.
- Crosstalk / ghosting - quantifying leakage between stereo views.
- Luminance and brightness uniformity - per‑view and across the panel.
- Contrast and black level - impact on perceived depth and image quality.
- Colorimetric performance - color shifts and consistency across views.
- Spatial resolution / MTF implications - how lenticular/parallax optics affect detail.
- Instrumentation and data capture
- Use of photometers, colorimeters, spectroradiometers and goniometric arrangements for angular measurements.
- Data processing and reporting
- Procedures to derive objective metrics, present angular maps and summarize performance for two‑view, multi‑view and integral imaging displays.
Note: IEC 62629-22-1 establishes measurement principles and procedures rather than application‑specific thresholds. Exact instrument specifications and pass/fail criteria are set by manufacturers, test labs or regulatory contexts.
Applications and Users
Who benefits from applying IEC 62629-22-1:
- Display manufacturers - validate design, optimize lenticular or parallax barrier elements, and benchmark optical performance.
- Test and calibration laboratories - provide repeatable, comparable optical test reports for autostereoscopic products.
- System integrators and OEMs - select displays that meet optical requirements for kiosks, digital signage, automotive HUDs and medical visualization.
- R&D teams and universities - evaluate prototypes, compare rendering algorithms and study perceptual impacts of optical characteristics.
- Procurement and certification bodies - use standardized measurements for supplier evaluation and acceptance testing.
