Abstract
The present invention provides a cinema screen that improves audience perception of brightness at, for example, a premium theater without additional illumination cost. The screen is produced from materials that also help mitigate speckle from laser illumination. The screen has properties and includes structures that may be tuned to the specific capabilities of the projection system, arrangement of the theater, and projector (and angle of projection, angle of viewing). Light reflected from the screen are direct toward audience members and away from walls and ceilings.
Claims13
A cinema screen, comprising:
- reflective structures spaced apart from each other and configured to reflect light projected onto the cinema screen;
- wherein the reflective structures have geometric properties that increase towards at least one edge of the cinema screen in a manner that causes more light reflected from the at least one edge of the cinema screen to be directed away from a side wall, ceiling, or floor of a theater and toward an audience position of the theater.
Dependencies are inferred from the claim text.
