Claim 16:
17. An edge-lit dual side view display comprising:
a waveguide comprising an inside transparent layer and an outside transparent layer spaced apart from and parallel to the inside transparent layer;
a light source attached to an edge of the waveguide and coupled into the edge-lit dual side view display;
a plurality of inside view liquid crystal (LC) pixels disposed within the waveguide and comprising an inside electrode proximal to the inside transparent layer, an outside electrode proximal to the outside transparent layer, a LC material sandwiched between the inside electrode and the outside electrode, and a plurality of outside blocking layers configured to block light scattered in the plurality of inside view LC pixels from propagating through the outside transparent layer, the plurality of outside blocking layers sandwiched between and in direct contact with the outside electrode and the outside transparent layer of the plurality of inside view LC pixels; and
a plurality of outside view LC pixels disposed within the waveguide parallel to and in-plane with the plurality of inside view LC pixels, the plurality of outside view LC pixels comprising an inside electrode proximal to the inside transparent layer, an outside electrode proximal to the outside transparent layer, a LC material sandwiched between the inside electrode and the outside electrode, and a plurality of inside blocking layers configured to block light scattered in the plurality of outside view LC pixels from propagating through the inside transparent layer, the LC material of the plurality of inside view LC pixels and the LC material of the plurality of outside view LC pixels being a polymer stabilized LC material controlled to scatter light by voltage.
