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 for controlled periods of time. Adjacent screens can be configured to selectively reflect light during different periods of time. The projector systems can be configured to project video onto their respective screens while the associated screen is configured to selectively reflect light rather than absorb light.
