[IP2-02] Enhancement of the color uniformity of a VHOE-waveguide-based AR eyewear display through drive signal management scheme

In this paper, we introduce a streamlined approach—using a drive signal management scheme on a micro-display for optical engine—to enhance color uniformity in AR eyewear displays. With VHOEs and a waveguide, our method achieves a full-color display, 30° FOV, and less than 3% ΔELab color non-uniformity, requiring only one waveguide and three RGB gratings.
