a second screen comprising a multilayer structure configured to diffusely reflect light in a second red wavelength band that does not overlap with the first red wavelength band, a second green wavelength band that does not overlap with the first green wavelength band, and a second blue wavelength band that does not overlap with the first blue wavelength band;
a third screen comprising a multilayer structure configured to diffusely reflect light in a third red wavelength band that does not overlap with the first or second red wavelength bands, a third green wavelength band that does not overlap with the first or second green wavelength bands, and a third blue wavelength band that does not overlap with the first or second blue wavelength bands;
a first projector system configured to project a first video onto the first screen, the first projector system configured to provide light within the first red wavelength band, the first green wavelength band, and the first blue wavelength band;
a second projector system configured to project a second video onto the second screen, the second projector system configured to provide light within the second red wavelength band, the second green wavelength band, and the second blue wavelength band; and
a third projector system configured to project a third video onto the third screen, the third projector system configured to provide light within the third red wavelength band, the third green wavelength band, and the third blue wavelength band,wherein the first screen and the third screen are positioned adjacent to the second screen so that the first video, the second video, and the third video are configured to be simultaneously viewed by a plurality of viewers in an immersive viewing environment.

Abstract
An immersive display system is disclosed that includes screens configured to mitigate reduction in contrast ratio due at least in part to peripheral light incident on the screens. The immersive display system includes at least two screens and at least two projector systems. The screens have a multi-layered structure configured to selectively reflect light in narrow wavelength bands. Each screen is configured to strongly diffusely reflect light in narrow wavelength bands that are different from the wavelength bands reflected by other screens in the immersive display system. Projector systems can be configured to provide light to associated screens in the narrow wavelength bands reflected by those screens.
