US Patent 10142620 Methods for optimizing retro-reflective display systems

Systems and methods provide a retro-reflective screen covered with a screen material. The retro-reflective screen has a plurality of retro-reflective screen elements positioned within the screen material. At least one of the plurality of retro-reflective screen elements is oriented so as to have an incident angle that is less than 45 degrees. Additionally, a portion of the screen material that corresponds to the at least one screen element has an incident angle that is greater than the incident angle of the at least one screen element. Additionally, the system also comprises at least one projector that (i) generates light characterizing an image or video and (ii) projects the light onto the retro-reflective screen.
