Abstract: MULTICOLOR LIQUID CRYSTAL DISPLAY A liquid crystal display device is described which includes two transparent sheets separated by a given distance, with liquid crystal material being disposed therebetween. Adjacent one transparent sheet is a stack of at least three pleochroic polarizers which act to separately polarize each incoming primary color wavelength. A second stack of at least three pleochroic polarizers are adjacent the second transparent sheet and are oriented to select the primary color polarizations exiting from the liquid crystal structure.

Abstract: MULTIPLE ELECTRON BEAM CATHODE RAY TUBE A multiple electron beam cathode ray tube has a plurality of cathodes in a plane to form an array. Grids on the same substrate are positioned in spaced relation about the cathodes so that a plurality of individually controlled electron beams are formed when appropriate potentials are applied to the cathodes and grids.
