  • Patent number: 5589852
    Abstract: A digital video system including a light source and a spatial light modulator system. Varying intensities of light to achieve gray shades either with a monochrome system or within each color can be accomplished in several ways. The intensity of the light source itself can be modulated to provide variation, the spatial light modulator elements can have their states in which light is directed to a surface to form a pixel modulated, or both.

  • Patent number: 5287096
    Abstract: A digitized video display system has a spatial light modulator which has individual elements which are controllable to produce individual beams which form an image. The individual elements are controllable at a frequency which is less than the critical flicker frequency of the human eye to produce individual beams which form an image. The individual elements are controlled to provide a luminosity control over individual pixels or voxels of the image.

  • Patent number: 5272473
    Abstract: A digitized video system with an increased viewing angle having a light projector and a display screen. The light projector generating a plurality of narrow light beams to impinge on the display screen at a plurality of associated points. The display screen has a transducer generating surface acoustic waves which traverse the associated points. This results in reduced laser speckle.

  • Patent number: 5206629
    Abstract: A digitized video system utilizes a spatial light modulator which has an array of deformable mirror cells with two or more memory cells associated with each mirror cell. A first decoder address one memory cell associated with most of the mirror cells of the array to display an image. A second decoder address one memory cell of each memory cell in the array to allow information to be stored therein. The array could be subdivided into several arrays with its own decoders as desired.
