Abstract
A method of operating an eyepiece waveguide having a first region and a second region includes directing light from a first projector to impinge on a first incoupling grating (ICG) and light from a second projector to impinge on a second ICG. Light from the first projector is diffracted into a first portion and a second portion of the first region of the eyepiece waveguide and out of the eyepiece waveguide. Light from the second projector is diffracted into a first portion and a second portion of the second region of the eyepiece waveguide and out of the eyepiece waveguide.
