A stiffening strip at selected edges of a screen may enable the use and mounting of a high-elastic modulus substrate screen material. Such screen materials may be engineered to provide polarization-preserving characteristics, and be applied to or part of the high-elastic modulus substrate. Furthermore, the stiffening strip may enable the use of screen vibration techniques to reduce speckle in display applications that use projection screens, particularly those display applications using illumination sources prone to speckle such as laser-based projection. The screen vibration may be provided by a vibrating device attached to the stiffening strip.

A display system comprises a projector combined with a retro reflective screen and a viewer distance from the projector such that the observation angle is less than approximately 2-3 degrees. The brightness of the image on the screen for the proposed display system is increased by a factor of 100-500 as compared to traditional display systems with for an equivalent power/intensity light source.

A special effects system designed to provide a projection surface or screen that can be animated or dynamically altered in its shape and/or size over time while video content is being concurrently projected from a video projector onto the altering projection surface. The video content and projection surface alterations are synchronized in time, e.g., on a pixel basis or other level of precision in some cases, such that the size and/or shape of the projected imagery, e.g., of a character, an animated object, and/or the like, matches that of the size and shape or outline of the present state of the dynamically alterable projection surface.

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.

A three-dimensional screen structure is a three-dimensional screen structure on which image light projected from an image light source is incident. The three-dimensional screen structure includes particles and a bind unit. The particles are three-dimensionally disposed and capable of transmitting or reflecting the image light. The bind unit binds the particles.

A display system configured to provide projection mapped augmentation of mechanically animated objects. These mechanically animated objects may take the form of a screen assembly with a projection surface, and a screen actuator may be included in the display system that is operated by a controller to move, to expand, or other otherwise operate the screen assembly so as to modify or morph the projection surface to move and/or change its shape and/or size. Hence, the screen assembly is animated. The display system further includes a projector operated by the controller, in a synchronized manner with the screen actuator, to project content onto the projection surface as it is moved and/or has its shape and/or size changed over time. The projected content is mapped to the various states and movement of the projection surface to avoid blow-by and to suit the changes of the projection surface.
