Abstract
A waveguide display includes a substrate transparent to visible light and a projector configured to generate display light for an image, where the display light includes display light for a first field of view (FOV) of the image and display light for a second FOV of the image. The waveguide display also includes a first input coupler configured to couple the display light for the first FOV into the substrate, a first set of gratings configured to couple the display light for the first FOV out of the substrate at a first two-dimensional array of locations of the substrate, a second input coupler configured to couple the display light for the second FOV into the substrate, and a second set of gratings configured to couple the display light for the second FOV out of the substrate at a second two-dimensional array of locations of the substrate.
