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 a tailored polarization state. Adjacent screens can be configured to selectively reflect light in orthogonal polarization states. The projector systems can be configured to project video onto their respective screens with light in a suitable polarization state. The screens can be further configured to selectively reflect light within a plurality of tailored spectral bands, the spectral bands being different for respective screens.
