Abstract: The disclosed technology relates generally to reflective displays, and more particularly to reflective displays configured to display images with customized and improved viewing parameters. In one aspect, a reflective display comprises a plurality of light-reflective microfacets configured to display an image by reflecting light incident thereon from a light source, wherein light rays reflected by different ones of the microfacets are directed in non-parallel directions.

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.

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.

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.

Abstract: Provided herein is a retroreflective article comprising a retroreflective film and a plurality of isosceles triangular pyramid prisms embossed on the back surface of the retroreflective film. The prisms are configured such that the article reflects an incident light beam into two reflected light beams that are offset from and on opposite sides of the incident light beam. The two reflected light beams can provide two viewing zones located at different positions relative to the incident light beam source.

Abstract: The disclosed technology generally relates to displays, and more particularly to display screens configured to display images having a shaped light profile. A display screen comprises a retroreflective display medium configured to display an image by retroreflectively reflecting incident light from a light source. The display screen additionally comprises a light profile shaping medium interposed between the retroreflective display medium and the light source. The light profile shaping medium is configured to shape an intensity distribution of light reflected from the retroreflective display medium prior to displaying the image to a viewer.

Abstract: The present disclosure provides systems and methods to enable significant improvements in display systems utilizing projectors and a retro-reflective (RR) screen through use of transparent or semi-transparent RR material. An aspect of the present disclosure provides methods for optimization of optical properties of the RR material to achieve desired optical transparency parameters. Another aspect of the present disclosure provides methods for specific use cases for flexible, transparent and semi-transparent RR display systems.
