Abstract: A ferroelectric liquid crystal-based light valve system with contrast control and a method for controlling contrast in a ferroelectric liquid crystal-based light valve system. The light valve system includes a light input, a ferroelectric liquid crystal-based spatial light modulator, an analyzer, and a voltage controller. The ferroelectric liquid crystal-based spatial light modulator includes signal processing electronics and an array of pixels. The array of pixels is configured to receive light from the light input and includes an array of pixel electrodes, a transparent electrode, and a layer of ferroelectric liquid crystal material. Each pixel electrode is independently switchable between a first voltage level and a second voltage level by the signal processing electronics. One of these levels may be a variable input voltage level. The analyzer has orthogonal directions of maximum transmissivity and minimum transmissivity.

Abstract: The display device includes a spatial modulator having a plurality of pixels and a periodical structural body having condenser elements corresponding to the pixels of the spatial modulator. Each of the pixels of the spatial modulator includes a plurality of color dots arranged in a first direction. A length of a peripheral region of the respective pixel encircling the plurality of color dots, measured in the first direction, is longer than a length of the condenser element of the periodical structural body, measured in the first direction. In addition, combinations of the pixels in the square, delta or mosaic arrangement with the condenser elements in the square, delta or mosaic arrangement are disclosed.

Abstract: In a suggested process for the transmission of a light bundle which is provided for illuminating picture points of a video picture and has a divergence angle and beam diameter determined by the way in which the light bundle is generated, the light bundle being coupled into a light guide and coupled out with an optical system for bundling a transmitted light bundle exiting the light guide, a divergence angle for the light bundle exiting the light guide is adjusted, by means of the optical system, proportionally to the divergence angle given by the manner in which the light bundle is generated, wherein the proportionality factor is the ratio of the given beam diameter before being coupled into the light guide to the beam diameter of the light bundle emerging from the optical system. A video system for carrying out the process has a suitably dimensioned optical system.

Abstract: A liquid crystal light valve includes a transparent substrate having a transparent electrode, a photoconducting layer and a dielectric mirror layer including a plurality of dielectric films formed in this order on a surface thereof, a transparent substrate having a transparent electrode formed on a surface thereof, and a liquid crystal layer held between the transparent substrates. The dielectric mirror layer includes a high packing density portion as the outermost layer on the liquid crystal layer side, and a low packing density portion with a packing density lower than that of the high packing density portion. This structure improves the optical characteristic and the manufacturing efficiency of the liquid crystal light valve.

Abstract: A liquid crystal light valve is provided with an array of photoconductive pedestals surrounded by a dielectric matrix material. Metal mirror pads are formed on top of each pedestal to form a high resolution metal matrix mirror, with each pedestal/mirror combination servicing one image pixel. The dielectric matrix forms a potential barrier between the individual photoconductive pedestals which prevents lateral charge migration between pedestals. The metal matrix mirror also shields the underlying photoconductive pedestal from photoactivation by the readout beam. The dielectric matrix material has a lower dielectric constant than the photoconductive pedestals, allowing the impedance of the photoconductive pedestals to match the impedance of the liquid crystal layer with a much thinner layer of photoconductive material than in prior LCLVs using a continuous photoconductive layer.
