摘要： An image display system provides a viewer with an experience of three dimensional images by presenting a composite image source. The system includes first and second image sources, a beamcombiner, a lens and a reflective element. The reflective elements reflects the image of the second image source to the beamcombiner. The first and second image sources, the beamcombiner, and the single lens present a foreground image and a background image, with the background image presented at a greater distance from the viewer than the foreground image. The viewer perceives the foreground image and the background image as part of a scene having depth.

摘要： A light valve such as an active matrix LCD between crossed polarizers, utilizing, for instance, individual transistors to control each "pixel area" of the LCD and storage elements to store video signal data for each pixel, with optically shielded "dead spaces" between pixels to eliminate electric field crosstalk and non-information-bearing light bleed through, is illuminated with a bright independent light source which creates a video image projected via specialized projection optics onto an internal or external screen without distortions, regardless of the angle of projection onto the screen. Use of heat sinks, IR reflective coatings, heat absorbing optics, optional fluid and a thermistor controlled pixel transistor bias voltage injection servo circuit stabilizes image performance, maintaining accurate color and contrast levels as the LCD changes temperature. In one embodiment of the invention, use of a multi-color LCD with a stepped cavity, producing different thicknesses of LCD for the different wavelengths that pass through it, allows a linear correspondence between the wavelengths passing through the LCD to produce true black, high contrast and CRT-like color rendition. A dichroic mirror arrangement is used to overlap differently colored pixels in the projected image. Use of lens arrays to expand pixels, where necessary, eliminating spaces between pixels, creating a continuous image with no apparent stripes or dots. A special venetian-blind type of screen is also disclosed and methods for using the system to view three-dimensional video are also explained.

摘要： Improved optical elements having rises and faces, which may have annular or linear grooves, such as Fresnel spherical or cylindrical lenses, and methods of making them, are disclosed wherein an opaque coating is imparted to the rises by methods including positioning pre-printed opaque elements on a substrate such that when the optical element is pressed, stamped, embossed or molded from the substrate, rises of the completed element comprise said pre-printed opaque elements. A reflective element is made by imparting a reflective coating onto a substrate and then a non-reflective coating to the rises, e.g. by applying non-reflective material to the element and selectively cleaning it to leave a coat of non-reflective material adhering to the rises but not the faces. Photoresist, photographic emulsion, or ink may be used as the coating. Unwanted light may also be minimized by using circularly polarized light.

摘要： A large-area display is composed of two or more adjacent panels, in which the overall display provides a consistent perception of depth (and/or other characteristics of the images) in all panels from each viewing position. This is accomplished by generating a first panel having a first repeating pattern in an arrangement of successive segments of the images, and generating a second panel to be displayed adjacent to the first panel, the second panel having a second repeating pattern in an arrangement of successive segments of the images that are in the same order as the first repeating pattern but starting at a different element of the repeating pattern from the first element of the first repeating pattern, and assembling the panels adjacent to each other, thereby allowing corresponding images to be displayed on the adjacent panels when viewed from a range of various view points.
