Abstract
A screen consists of a clear mechanically stable substrate and a bulk diffuser portion which is as close to the front lenticules as possible. The diffuser may be dispersed within the lenticules or in a separate area immediately adjacent to them. The screen may be a two element screen, either the front or the rear element having the clear substrate. Surface diffusion may be used as an alternative, or in addition to, the bulk diffuser.
