Claim 12:
13. A system comprising:
a combiner waveguide having a first side and a second side;
optics on the first side of the combiner waveguide;
an illumination system on the first side of the combiner waveguide to direct a light from one or more light sources to the optics, without passing through the combiner waveguide;
a liquid crystal on silicon display panel (LCOS) on the first side of the combiner waveguide to modulate the light from the optics and to direct the modulated light back to the optics;
an in-coupler to the combiner waveguide to receive the modulated light from the LCOS, after it passes through the optics;
such that the illumination light to the LCOS and the modulated light from the LCOS both pass through a shared subset of the optics, and the optics, the illumination system, and the LCOS are on the first side of the combiner waveguide.
