A full color eyewear display with over 85% see‐through transmittance and 2500cd/m2 brightness was developed. Very low color crosstalk, less than 0.008 Δu'v' uniformity and 120% NTSC color gamut were achieved. Waveguides with two in‐ and out‐coupling hologram elements enabled simple configuration with side‐mounted microdisplays.

A full‐color eyewear display with over 85% see‐through transmittance with a 16° horizontal field of view was developed. Very low color crosstalk, less than 0.008 Δu′v′ uniformity, and 120% NTSC color gamut were achieved. Waveguides with two in‐ and out‐coupling reflection volume hologram elements enabled a simple configuration that has an optical engine beside the user's temples. The reflection volume hologram elements used on the waveguides realized a small thickness of 1.4 mm for each waveguide, and an out‐coupling reflection volume hologram used as an optical combiner contributed a high see‐through transmittance of 85% due to its wavelength selectivity. However, there are technical challenges in achieving a reasonable screen size and quality color images with optics that utilize holographic waveguides because holograms have large chromatic dispersions compared to conventional optical elements such as lenses and mirrors. Approaches to overcome these issues are described.

High-luminance (~1000cd/m 2 ) and high-uniformity see-through eyewear display has been developed by using two in-coupling and one out-coupling reflection volume holograms on optical waveguide glass. This novel volume hologram design achieves an ideal eyewear display for augmented reality with high transparency, high luminance and low power in various environments.
