1. A display system comprising:
illumination optics configured to produce illumination light;
a ferroelectric liquid crystal on silicon (fLCOS) panel configured to produce image light by modulating image data using the illumination light, the fLCOS panel comprising:
a ferroelectric liquid crystal (fLC) layer, and
a planar layer of silver configured to receive the illumination light through the fLC layer and configured to reflect the illumination light, the fLC layer being configured to transmit the illumination light reflected off of the planar layer of silver as the image light; and
a waveguide configured to propagate the image light.
