1. A display system comprising:
a frame;
a display module configured to generate main image light;
a waveguide having a lateral periphery mounted to the frame, wherein the waveguide is configured to form an optical combiner that combines the main image light with real world light;
an output coupler on the waveguide, wherein the output coupler is configured to transmit the real world light in a first direction and is configured to redirect the main image light within a field of view;
a substrate having a lateral periphery mounted to the frame, wherein the substrate overlaps the waveguide in a second direction parallel to the first direction; and
peripheral light sources mounted to the substrate, wherein the peripheral light sources are configured to emit peripheral image light at a periphery of the field of view, wherein the peripheral light sources comprise a first set of light sources and a second set of light sources, wherein the first set of light sources faces a third direction, and wherein the second set of light sources faces a fourth direction opposite the third direction.
