Title: Translucent projection screen contg a - silicone rubber layer
IPC: G03B21/56
Filed: 1970-04-04
Abstract: New translucent projection screen. Comprises transparent plate with a diffusing face, and a layer of transparent elastic material between it and a second similar transparent plate parallel to the first and close to it, the material being in contact with at least part of each of the faces to permit movement on a closed path of one of the plates in relation to the other in order to suppress scintillation in the projected images. The plates may be of glass with a light diffusing coating having a different refractive index and the elastic material may be a gel, a silicone rubber or a rubbery adhesive which is transparent and of different refractive index from the glass plates. The use of the screen reduces visual fatigue.
