ABSTRACT:
Various forms of light-diffusing screen are disclosed comprising plastics sheets having surface texturing of some kind, adding to or modifying the diffusing effect. The plastics sheets may have bulk diffusing characteristics in addition to the surface texturing. The surface texturing may be produced by, for example, embossing or by molding the plastics against a textured surface such as a "brushed" surface or a ribbed or grooved surface imparting asymmetrical diffusion characteristics to the screen.
