Abstract
A dual side view display includes a waveguide with an inside transparent layer and an outside transparent layer spaced apart from and parallel to the inside transparent layer, and a plurality of inside view liquid crystal (LC) pixels and a plurality of outside view LC pixels disposed within the waveguide. The plurality of outside view LC pixels are disposed within the waveguide parallel to and in-plane with the plurality of inside view LC pixels. The plurality of inside LC pixels includes 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. Also, the plurality of outside view LC pixels includes 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.
