  • Patent number: 6791570
    Abstract: The invention relates to an autostereoscopic method and a device for the three-dimensional representation of information according to a barrier-, lenticular-, prismatic mask-, or similar method using flat-panel displays (liquid crystal-, plasma-, electroluminescent- or other displays) for use in the computer and video technology, games and advertising, medical engineering, virtual reality applications, and other fields. According to the invention, the image points are proportionally tracked to lateral movement of the observer by shifting, for each colored subpixel, of the intensities of the colored subpixels to horizontally adjacent colored subpixels. The method can be used with known devices. It becomes especially useful when, for each image point, n+1 adjacent colored subpixels are addressed. Observers moving sideways continue to see the image in practically consistently high quality.

  • Patent number: 5774262
    Abstract: An optical system for the two- and three-dimensional representation of information by the use of transmission displays for the computer and video technology, for head-up displays for aviation and space flight, in advertising and presentation, in medical engineering, in the field of virtual reality and in other fields comprises: a light-source arrangement with at least one point or line source of light, a collimating optics for rendering the light parallel, a transmission display, a prism mask with prisms in a matrix arrangement, the prisms having two different prism angles, a field lens as a focussing optics as well as a phase mask. The image can be well seen by several viewers without any aid, the viewers being able to move laterally and vertically as they like. It is possible to offer two different TV programs to two or more persons at the same time. If all the viewers watch the same program, no sequential switching-over is necessary.
