摘要： An optical polarization state modulator assembly for use in a stereoscopic three-dimensional image projection system includes a spatial light modulator, a light source emitting multiple wavelength components of light for incidence on the spatial light modulator, and a projection lens. A polarization converter system cooperates with the spatial light modulator to produce in alternating sequence polarized light carrying first and second perspective view images of a scene in different ones of first and second subframes. A polarization modulator, in response to first and second drive signals, imparts to, respectively, the image-carrying polarized light a first output polarization state during the first subframe and to the image-carrying polarized light a second output polarization state during the second subframe. The image-carrying polarized light in the first and second output polarization states propagates through the projection lens for transmission to an observer.

摘要： Self-compensating, quasi-homeotropic liquid crystal devices (100, 200, 300, 400) overcome the contrast reducing effects of smaller pretilt angles. The devices exhibit extremely high contrast ratio but at the same time suppress fringe field-induced disclination lines in high pixel density and small pixel size quasi-homeotropic displays. The surface pretilt (520, 540) and cell twist (570) angles are set at values that, in combination, contribute to establishing a cuspate singularity in the contrast ratio for normally incident light in response to a drive signal switching the liquid crystal device to the OFF director field state that provides nearly 0% optical efficiency. The OFF director field state corresponds to a subthreshold drive level that provides for the liquid crystal device self-compensation for in plane optical retardation. Setting the cell gap (“d”) to provide substantially 100% optical efficiency in response to a value of the drive signal switching the liquid crystal device to the ON director field state achieves optimal dynamic range for the liquid crystal device.

摘要： A method and an apparatus for addressing a liquid crystal display (10) groups together row electrodes (28) and applies the same row addressing signal to all row electrodes in the group (48). The groupings are cyclically changed in successive addressing cycles. An image data conditioner (54) determines for use in calculating the column signals a pixel information value based upon the information values of one or more of the pixels in the selected group of row. Grouping the row electrodes reduces the effective multiplex ratio, thereby increasing the selection ratio and producing a faster responding display having higher contrast and a wider viewing angle.

摘要： A process and apparatus for the production of an orientation layer on a plane surface of a plate, and a liquid crystal substrate plate produced thereby. By the process of evaporation from a source, orientation layers are deposited on the plane surfaces of a plurality of liquid crystal substrate plates used for application in liquid crystal displays. To obtain a uniform orientation of the optic axis of the liquid crystal with regard to the azimuthal alignment by means of the preferred direction caused by the orientation layer on the surface, the plates are moved in a direction crosswise to the evaporation direction during the evaporation process. The field of the particle stream emanating from the source is limited by an aperture in an aperture screen which is introduced between the source and the plates. The plates pass completely through the particle stream during the course of the evaporation operation. The finished plates include an approximately 5 nm thick orientation layer. In the apparatus, the plates are held in a wagon which is moved along rails by means of a toothed rack and a toothed pinion.

摘要： A liquid crystal display based on the bistability effect, wherein the distance between the support plates is smaller than 10 .mu.m and the total twist of the liquid crystal is between 180.degree. and 360.degree., preferably about 270.degree.. Over the entire viewing area of the display, randomly distributed spacers are provided. Because of these measures, the range of the bistable action is so narrowed that the display can be driven with operating voltages outside this range, using conventional multiplexing techniques. A high degree of multiplexing with short switching times and excellent contrast is obtained. The range of viewing angles is very large and independent of the direction of illumination.

摘要： An electro-optical display for the display of dark symbols against a bright background, wherein except for fine separation lines the front and rear cell plates are almost entirely covered with isolated electrode elements. The regions of overlap between these various front and rear electrode elements define the areas of the selectable display segments. The display employs an electro-optic media requiring no polarizers, for example, cholesteric liquid crystals to which has been added pleochroic dyes, or electrophoretic suspensions. The display device is addressed through the application of appropriate signals to the electrodes so that a vanishingly small potential difference lies across the liquid crystal layer in the region of the selected display segments which remain dark. In all the other regions of the display, however, there exists a potential difference which is larger than the transition voltage of the electro-optical medium, and these regions therefore appear as a bright background. The addressing is preferably carried out using unipolar pulsed signals which are applied to the electrode elements of the front and rear cell plates, with those electrodes corresponding to optically selected display segments receiving signals having the same phase and amplitude.
