Abstract
The present invention is directed to wearable display technologies. More specifically, various embodiments of the present invention provide wearable augmented reality glasses incorporating projection display systems where one or more laser diodes are used as light source for illustrating images with optical delivery to the eye using transparent waveguides. In one set of embodiments, the present invention provides wearable augmented reality glasses incorporating projector systems that utilize transparent waveguides and blue and/or green laser fabricated using gallium nitride containing material. In another set of embodiments, the present invention provides wearable augmented reality glasses incorporating projection systems having digital lighting processing engines illuminated by blue and/or green laser devices with optical delivery to the eye using transparent waveguides. In one embodiment, the present invention provides wearable augmented reality glasses incorporating a 3D display system with optical delivery to the eye using transparent waveguides. There are other embodiments as well.
