Provided is a curved light guide screen. A plurality of vertically aligned light guides are arranged into light guide magnifying layers. Spacers are disposed between any two adjacent light guide magnifying layers, proximate to the magnifying output ends, to position the magnifying layers and define an orientation for the magnifying output ends. A curved viewing surface is defined having a concave, convex or complex curvature shape depending on the size, shape and positioning of the spacers. The spacers may have a variety of shapes, and may be flexible, semi-rigid or rigid. A case houses the light guide magnifying layers and spacers, as well as an image source and associated lenses. A related method of making a curved light guide screen is also provided.
A circuit for implementing a registration-free, contiguous conductive plane. A circuit may include a plurality of conductive structures in a first plane. The circuit may further include a contiguous conductive equipotential surface in a second plane parallel to the first plane. The circuit may further include activation means configured to adjust an electric field between the first and second planes thereby activating one or more structures in the first plane by increasing a potential difference between the first and second planes to a threshold level deemed to constitute an active state. The circuit may further include deactivation means configured to adjust the electric field between the first and second planes thereby deactivating one or more structures in the first plane by decreasing the potential difference between the first and second planes below a threshold level deemed to constitute a deactivated state.
