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.
