A VIEWING SCREEN AND MASKLESS METHODS FOR MANUFACTURING

摘要

By providing light-directing features, such as grooves or lenses, cut or embossed into one surface of a film substrate intended for a viewing screen, tapered optical waveguides can be fabricated from a monomer mixture layer without the need for a separate mask that must be removed after the photopolymerization process. Alternatively, a gradient-index lens array can be used to concentrate and direct the light to form the waveguides in the monomer mixture layer.
