Abstract
The present disclosure provides a display system that may comprise a retro-reflective screen configured to reflect incident light along a direction that is opposite to the direction of propagation of the incident light, and a projector that may project light characterizing an image or video to the retro-reflective screen. An array of optical elements or an individual optical element may be positioned between the retro-reflective screen and the projector. The array of optical elements or individual optical element may direct the light from the projector to the retro-reflective screen in a manner such that the image or video is viewable by a user at an observation angle of at least about 2 degrees.
