The present invention relates to display systems that use materials made from various arrangements of lenses and other optical materials. Careful design and use of these materials can be used to achieve display systems with many desirable visual effects having applicability in image and video displays, virtual reality, immersive environments, as well as in architecture, art, entertainment, and interactive systems.

A reflective screen including a lens layer having a Fresnel lens shape with a plurality of unit lenses and a reflective layer formed on the unit lenses to reflect light. The unit lenses protrude from a video source side to a back surface side in the thickness direction of the lens layer, the lens layer has a flat edge section where a portion of the back surface side serves as a flat surface, and h1min-h2 > 0 is satisfied, where h1min is the minimum height distance in the thickness direction of the lens layer from a position of the lens layer most on the video source side to a position of the unit lenses most on the back surface side, and h2 is the height which is the distance from the flat surface of the flat section to the position of the unit lenses most on the back surface side.

A system is provided. The system includes a translucent display positioned such that a first face is a display face and that a second face is a projection face and at least one projector configured to project an image on the second face of the translucent display. The image is displayed on the first face. The system also includes at least one sensor configured to transmit a signal when triggered and a projector controller in communication with the at least one projector and the at least one sensor. The projector controller is programmed to receive a signal from the at least one sensor and instruct the at least one projector to project at least one image on the translucent display in response to the signal from the at least one sensor.

An article used as black or dark-colored front-projection screen includes two distinct diffusely reflecting scattering elements, taking the form of parallel sheets or planes, qualified first and second scattering elements, wherein the first scattering element is translucent or transparent and the second scattering element is of dark color.
