Questions about Waveguide-Based Near-Eye Display Systems: 1. How do waveguide-based near-eye display systems differ from traditional display technologies?
- Waveguide-based systems use mirrors to reflect light into the user's eyes, resulting in a more compact and lightweight design compared to traditional displays.
2. What are the key advantages of using 3-D k-vectors in analyzing waveguide-based near-eye display systems?
- 3-D k-vectors allow for a comprehensive analysis of light propagation within the waveguide, leading to optimized display performance and image quality.
Original Abstract Submitted
Techniques disclosed herein relate to waveguide-based near-eye display systems and techniques for analyzing the waveguide-based near-eye display systems using three-dimensional (3-D) k-vectors (wave vectors) in 3-D k-sphere. In one example, a geometrical waveguide display may include a substrate and a first plurality of transflective mirrors in the substrate, the first plurality of transflective mirrors characterized by a tilt angle of n×180°/N with respect to a surface of the substrate, where N is an odd number and n is an integer smaller than N.
