Title: Jong Young Hong and Waveguide Display Innovation

Introduction

Jong Young Hong is an inventor based in Boulder, Colorado, associated with Apple Inc. His patent work includes a waveguide display design intended to improve how different color channels are directed toward an eye box.

Latest Patents

Hong is named on 1 patent: “Waveguide Display with Total Internal Reflection Band Between Color Channels.” The invention describes a display waveguide with a grating medium between two substrates. A cross-coupler directs light toward an output coupler, which may use volume holograms to guide light out of the waveguide and toward an eye box.

The cross-coupler may use a surface relief grating to diffract the fields of view for different color channels across angles on both sides of the waveguide’s total internal reflection transition angle. This approach is designed to reduce dark bands that could otherwise appear in the displayed image.

Career Highlights

The available information identifies Hong as an inventor associated with Apple Inc. and documents his contribution to waveguide display technology through this patent. The invention addresses a specific optical-display challenge: maintaining more consistent color-channel coverage at the eye box.

Collaborations

Hong’s listed coworkers include Friso Schlottau and Byron R. Cocilovo. Their names are provided as collaborators associated with his professional context.

Conclusion

Jong Young Hong’s documented patent contribution focuses on improving waveguide display performance by managing light across color channels and reducing visible dark bands.
