Abstract:
Examples are disclosed that relate to a display device. One example provides a display device comprising a projector and a pre-expander optic configured to replicate an exit pupil of the projector in at least a first direction, the pre-expander optic comprising a plurality of spectrally-selective pupil-replicating elements to form at least two exit pupils at different spatial locations, each exit pupil being for a different spectral band. The display device further comprises a waveguide comprising at least two incoupling pupils, each incoupling pupil configured to receive light from a corresponding exit pupil of the pre-expander optic, and the waveguide configured to replicate each corresponding exit pupil in at least a second direction and output the light received toward an eyebox.

Claim (Index 17):
A display device, comprising:\n a projector; a first waveguide configured to expand an exit pupil of the projector in at least a first direction, the first waveguide comprising a plurality of spectrally-selective elements configured to form at least two exit pupils at different spatial locations, each exit pupil being for a different spectral band; and a second waveguide configured to output light from the projector toward an eyebox, the second waveguide comprising at least two incoupling pupils each configured to receive light from a corresponding exit pupil of the first waveguide, and the second waveguide also comprising, for each exit pupil of the first waveguide, an expansion structure configured to expand the exit pupil in at least a second direction.
