Abstract
The present disclosure provides a display system that may comprise a retro-reflective screen having retro-reflective screen elements that reflect incident light and comprising at least one projector that (i) generates light characterizing an image or video and (ii) projects the light on the retro-reflective screen, wherein the projected light has a nominal profile. Additionally, the retro-reflective screen may reflect the light characterizing the image or video to a viewer in a manner such that an intensity profile of the light is offset away from the projector and has a uniform brightness profile within a field of view of the viewer with respect to the retro-reflective screen. The projected light may have an intensity drop-off that has at least a 200% or 2×, or at least a 500% or 5× intensity reduction per 0.5 degrees outside of the nominal region.
