Abstract

In this paper, we present an enhanced approach—a drive signal management scheme employed on a micro-display device of optical engine—to retune the color uniformity of an Augmented Reality (AR) eyewear display with a the Volume Holographic Optical Elements (VHOEs)-based waveguide. Our method streamlines multiplexing complexity, necessitating just one optical waveguide and three RGB gratings to attain a full-color eyewear display with nearly a 16° horizontal field of view (FOV) and less than 3% ΔELab color non-uniformity.
