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 one screen having an array of micro-lenses, a light polarization layer on top of the array of micro-lenses, a polarization rotation layer, a light reflection layer, and a section of non-polarizing light scattering material for individual micro-lenses in the array of micro-lenses. In use, light from a projector associated with the screen is substantially scattered by the non-polarizing light scattering material and light from a projector associated with a different screen in the immersive display system is substantially absorbed by the polarization layer.
