International Classification:

G03B 21/14

US Classification:

353 77, 353 98, 353 79

Abstract:

A system for projecting changeable electronic content, such as video or digital still images, onto a curved surface. The system includes a housing, a reflector within the housing, and a projector. The housing has an exterior surface and an interior space. At least a portion of the exterior surface is a curved display surface capable of displaying electronic content projected upon it, and at least one portion of the exterior surface has an aperture through the exterior surface to the interior space. The projector is located proximate the aperture for projecting content through the aperture to the reflector. When the projector receives converted content and projects the converted content through the aperture to the reflector, the curved display surface displays the converted content undistorted to a viewer. The system can also provide for display of branded content on a product container having a shape corresponding with the brand.

US Classification:

359449, 359443, 359457, 359460

Abstract:

A system for projecting content at an angle to a rear projection screen. The system includes a projector configured for projecting changeable electronic content and a rear projection screen for receiving the projected content at an angle and displaying the projected content. The rear projection screen includes a turning film having prisms facing toward or away from the projector. For prisms facing toward the projector, a protective film covers the turning film. When the projected content is displayed on the rear projection screen, the content has a substantially uniform appearance.

International Classification:

H04N 5/74
G03B 21/28

US Classification:

348744, 353 69

Abstract:

A system for projecting changeable electronic content, such as video or digital still images, onto multiple surfaces. The system includes a projector, one or more reflectors, and at least two display surfaces. The projector via a reflector projects content onto one of the display surfaces and either directly or via another reflector projects content onto the other display surface. The display surfaces can be multiple curved surfaces, multiple planar surfaces in different viewing planes, or a curved surface and a planar surface. For the curved surfaces, the projector receives converted content and projects the converted content such that the curved surface displays the converted content undistorted to a viewer. The system can also provide for display of branded content on a product container having a shape corresponding with the brand.

International Classification:

G03B 21/14
G03B 21/62

US Classification:

353 20, 353 69

Abstract:

A system for projecting content onto a shaped screen. The system includes a projector configured for projecting content having a particular shape and a rear projection screen with an optically active light redirecting film, such as Fresnel lenses, for receiving and displaying the projected content. The rear projection screen and the optically active light redirecting film each have a shape substantially conforming to the particular shape of the content. The optically active light redirecting film, such as a Fresnel lens sheet, provides for brightness uniformity and a wide view angle. The rear projection screen can include a turning film for displaying content received from the projector at an angle.

US Classification:

312 101, 312114

Abstract:

A transparent display booth for displaying products and providing product-related information. The display booth includes a bottom panel, a back panel, a transparent front plate opposite the back panel, and a transparent display device located co-extensive with the front plate. The bottom and back panels have reflective inner surfaces. The transparent display device can electronically display product-related information, and products located in an interior of the display booth are viewable through the transparent display device to showcase the products and offer them for sale. Multiple transparent display booths can be combined to form a networked retail system.
