Paper Abstract

DigiLens Switchable Bragg Grating (SBG) waveguide technology for transportation AR HUD consumer products enables switchable, tunable and digitally reconfigurable color HUDs with a field of view, brightness and form factor surpassing those of competing technologies. DigiLens waveguide gratings are printed into a proprietary polymer and liquid crystal mixture that can provide any required combination of diffraction efficiency and angular bandwidth in a thin waveguide with high transparency and very low haze. DigiLens waveguides can be laminated to integrate multiple optical functions into a thin transparent device. Our current reference designs for dashboard mounted and wearable ARHUDs will be presented.
