"Screen for the restitution in relief of cinematographic and fixed views", characterized by being constituted by multiple conjugate concave-convex curvatures, which are confused with each other, so as to constitute a uniform surface, presenting between said curves a parallelism of such kind, that establishes a symmetrical angular restitution in convergent and divergent directions in relation to the visual axis of the screen.
