Abstract
The present disclosure provides a display system comprising a retro-reflective screen having retro-reflective screen elements that reflect incident light. Each of the retro-reflective screen elements can include three intersecting planes. At least one of the three intersecting planes intersects an adjacent plane at an angle that is 90° with an offset greater than 0°. The display system can further include at least one projector that projects the light onto the retro-reflective, which light characterizes an image or video. The retro-reflective screen having the retro-reflective screen elements can reflect the light at a cross-talk that is decreased by at least 10% and/or an intensity that is increased by at least 5%, as compared to a retro-reflective screen with retro-reflective screen elements having planes that each intersects an adjacent plane at an angle of 90° without the offset.
