Original Abstract Submitted
An AR or VR display device. First and third input gratings receive light of a first color from first and second projectors, respectively, coupling the light into a first waveguide. Second and fourth input gratings receive light of a second color from the first and second projectors, respectively, coupling the light into a second waveguide. An output diffractive optical element couples light out of the waveguides towards a viewing position. The first and second projectors provide light to the input diffractive optical elements in directions that are at a first and second angle, respectively, to a waveguide normal vector. The output diffractive optical element couples light out of the waveguides in a first range of angles for light from the first projector and in a second range of angles for light from the second projector, the first range of angles and the second range of angles differing but partially overlapping.
