摘要:
A three-dimensional (3D) display device combining two-dimensional (2D) images from two image sources to create a 3D image. The 3D display device utilizes a beam combining film that includes a prismatic front surface and a planar back surface. The film transmits light striking its back surface at particular incidence angles. A first 2D image source provides a foreground image and a second 2D image source to provide a background image. First and second liquid crystal displays may be arranged with display surfaces proximate to top and bottom edges of the beam combining film and at angular offsets to emit light corresponding with a 2D image stream onto the back surface of the beam combining film at one of the film's incidence angles. The 2D image streams striking the back surface of the film are combined by the film and transmitted from the front surface as a single autostereoscopic video image.

A three-dimensional (3D) display device creating 3D illusions or effects within a contained space or volume. The device includes a front sidewall providing a viewing window to an interior of the display device. The device includes a transparent rear projection screen with a front surface facing the viewing window that is spaced apart a distance from the front sidewall. A media source projects a two dimensional (2D) image onto a back surface of the projection screen in a direction that is oblique to the front sidewall. The projection screen is positioned such that the front surface is angled away from the front sidewall, whereby the front surface is oblique to the viewing window. A leading edge of the projection screen is proximate to the front sidewall and a trailing edge of the projection screen is distal to the front sidewall with the front surface angled away from the front sidewall.

摘要:
A projector for projecting diffracted light in a selectable pattern and/or animation on a display surface. The apparatus includes a light source providing one or more beams of coherent light from one or more lasers. The apparatus includes a diffraction assembly in the path of the light source to generate diffracted light by diffracting the laser light with one, two, or more diffraction grating patterns and, optionally, with a diffraction glass or other material. An active mask is provided with a raster that receives the diffracted light and that includes a plurality of optical shutter elements that are selectively operable to project a portion of the diffracted light from the active mask toward the display surface. In one example, the active mask includes a liquid crystal display panel to provide a grid of addressable programmable pixels that are turned on and off to project portions of the diffracted light.

An apparatus for simulating flames using fabric flame sheets or elements. The apparatus includes a fan or blower for producing a volume of air flow and two or more flame elements positioned in the fan air flow. First and second light sources, such as high powered light emitting diodes (LEDs), are provided to produce light beams having two differing colors such as an amber beam and an orange/red beam. The light beams are directed so as to mix or cross on or near the flame elements when the flame elements extend outward from their mounting location into the fan air flow. Each of the LEDs has a brightness level that can be tuned or adjusted by a controller, which may be manual or may be automated to modify the brightness level of at least one of the LEDs and typically both LEDs during the operation of the flame simulator.
摘要:
An apparatus for generating light sheets useful in flame simulators or other lighting displays. The apparatus includes first and second light strips, which may include light emitting diodes of differing colors. Each of the light strips is mounted on support members that are mounted in the apparatus to rotate such that the orientations of the light strip outputs can be adjusted. The support members are mounted on end plates that can be rotated such that the light strips can be moved to be into a single plane or into differing planes, and the support members may be rotated to set the orientation of the light strips. Positioned over each light strip is an elongate projection lens such as a cylindrical rod. The light generated by the light strips is focused by the projection lenses into a sheet of light by converging and combining the light from the light strips.

An apparatus is provided for generating or creating an autostereoscopic or three-dimensional (3D) display. The apparatus has a foreground display assembly including a display element such as a transparent projection screen film and a projector projecting a first set of two-dimensional (2D) content onto a rear surface viewable by a viewer via a front surface. The apparatus includes a background display assembly including a display element displaying a second set of 2D content. The apparatus includes an intermediate display assembly including a display element, such as an optical shutter window, positioned between the foreground display element and the background display element. This assembly includes a projector projecting a third set of 2D content on the front or rear surface of the optical shutter window. The first, second, and third sets of 2D content are concurrently visible and the use of three spaced apart display planes creates a 3D illusion.
摘要:
An apparatus providing a viewer with a blend of displayed and reflected content. The apparatus includes an emissive display device with a display screen operable providing digital content. The emissive display device includes a light source selectively articulating and transmitting light through the display screen at a particular illumination level to display digital content such as text and graphics. The apparatus includes a thematic overlay positioned over the display screen with a front surface configured to provide diffuse reflection of light striking the front surface from a viewer space such that the front surface appears substantially opaque to the viewer and the viewer cannot see the display screen when the light source is inactive or at low brightness. When the light source is in active mode, the displayed content is visible as emissive display content concurrently with the diffuse reflection content but the display screen remains hidden from view.
