Abstract
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.
