    摘要: A 3-D display including a light source which emit lights in a flat plate shape, a liquid crystal panel for color images which displays left eye images and right eye images respectively with left eye pixels and right eye pixels, and color filters each being formed for pixels of a number of the observing positions of 3-D images, which convert emitted lights from the light source into very small luminescences of red, green and blue being aligned in a predetermined order. The traveling direction of the emitted lights from the light source and given to a observer is decided depending on each color.

    摘要: A three-dimensional display device comprising an evacuated enclosure (45). A phosphor coated screen (44), means to rotate the phosphor coated screen, one or more electron gun (41-43) and control means to drive the one or more electron gun. Sequential image Frames (FIGS. 2b-2f) are written to the rotating phosphor coated screen (44) by the one or more electron gun (41-43) for a number of image sectors. Provided the screen rotates sufficiently rapidly and the phosphor coating has the required persistence the human eye will perceive a three-dimensional image within the display volume swept out by the phosphor coated screen. In the preferred embodiment the planar screen (44) rotates about a vertical axis with three electron guns (41-43) located below the display volume directed upwardly towards the center of the display volume. In another embodiment the display screen is in the form of a helix (51) with the electron gun (52) being aligned substantially along the axis of rotation of the helix.

    摘要: Three-dimensional objects are displayed in real time within a solid volume of optically transparent material by utilizing two infrared laser beams of different wavelengths to create visible light inside the display material via a two-photon upconversion process. Objects comprising points, lines, surfaces, and volumes are drawn by decomposing them into a set of small three-dimensional cells or "voxels" located at specific coordinates inside the display medium. Individual voxels are addressed and activated by intersecting the two invisible infrared laser beams at the appropriate coordinate locations. The display material is tailored to provide efficient upconversion in the region of intersection, with minimal visible light generated outside this region by either one of the infrared beams alone. Typical media are rare-earth-doped glasses or crystals having low phonon energies. The general methods for selecting and producing the display material, along with a plurality of system configurations for addressing the display, are disclosed.

    摘要: A projection system is constructed using a field emission device 10. A single monochrome FED 10 can be used with projection system electronics 40 and lens 20 to create a monochrome picture on screen 30. Alternatively, a single monochrome FED 10 can project the proper image through color wheel 150 to create a color image which is projected by a lens 20 onto a separate surface 30. In yet another embodiment, a first FED 10 which projects a red image, a second FED 10 which projects a green image, and a third FED 10 which projects a blue image, and three clear focusing lenses 20 create a full color image on screen 30. In this configuration, if the three lenses 20 are colored red, green and blue, then the three FEDs 10 need only present the image data for each color in black, grey, and white. The FED projection system could also utilize a color FED 10 and a clear focusing lens 20 to create a full color image on screen 30. This full color FED 10 could create its color image by using red, green, and blue phosphor stripes 90 which are energized by its cathode 80 configured with full pixels or sub pixels 160. In another embodiment the FED projection system provides a three-dimensional display image on screen 30. The use of FED 10 facilitates a projection system which has low power consumption, reliable electronics, consumes less space, and interfaces to multimedia input signals 50.

    摘要: Apparatus for masking a displayed image by mixing the image with a secondary image that is electronically generated to be related to the primary image that when combined with the primary image obscures viewing of the primary image. The primary image is generated in the form of a first set of wavelength bands and the secondary image is a second set of related wavelength bands. A filter is provided to absorb the second set of wavelength bands to permit secure viewing of the primary image.
