Abstract: The light valve comprises transparent substrates and a rear plane separated from the substrate by a twisted, nematic liquid crystal (LC) layer with LC molecules with a director axis. The rear plane contains reflecting electrodes with edges parallel, or orthogonal to the director axis of the molecules, when the director axis is projected onto the rear plane surface. The molecules in the twisted, nematic layer are so oriented by transparent substrate rubbing as to bee oriented in a first direction, twisted from horizontal or vertical of the rear plane rubbing. Independent claims are included for a projection system.

Abstract: A two-electrode nematic liquid crystal display (LCD) device with inherent storage effect is described. The device, which can be of either the homogenous or twisted nematic type comprises a liquid crystal material 18 enclosed between two electrodes 12 whose surfaces are treated to set the liquid crystal material to anisotropic surface anchoring force sufficiently weak to prevent the restoration of the device to its quiescent state once it has been driven temporarily to to its active state by application of an electric field to electrodes 12.

Abstract: A method for preparing an alignment layer surface provides a surface on the alignment layer. The surface is bombarded with ions, and reactive gas is introduced to the ion beam to saturate dangling bonds on the surface. Another method for preparing an alignment layer surface provides a surface on the alignment layer. The surface is bombarded with ions and quenched with a reactive component to saturate dangling bonds on the surface.

Abstract: A liquid crystal element, a packaging structure providing thermal and alignment control, a display device including the same, and methods of fabrication and assembly are provided. The liquid crystal element includes: a semiconductor wafer, having microcircuitry and an array of reflective pixels; a layer of electro-optical responsive liquid crystal medium, of uniform thickness, disposed on the reflective pixels; a transparent conductive layer positioned on the liquid crystal, being substantially parallel to the reflective layers, to ensure a uniform thickness of the liquid crystal; and an insulative transparent layer provided on the conductive layer. The liquid crystal element is laminated to an optically flat substrate to limit the out-of-plane distortions thereof. The structure formed by element and substrate are disposed in a substrate holder which is mounted to a wiring board, and coupled to voltage sources for actuating the liquid crystal. During mounting, an aligning fixture is used to ensure proper orientation of the element relative to the related optical elements. Once the element is positioned, a heat sink is coupled to the rear surface of the substrate holder to dissipate heat.

Abstract: ELECTRIC FIELD GRADIENT EXCITED LIQUID CRYSTAL CELL HAVING BISTABILITY A liquid crystal storage device includes a smectic phase liquid crystalline medium in spaced relationship with at least three separated electrodes, the first of which provides a ground plane and is in contact with the liquid crystal medium; a second electrode, spaced from the first electrode, is arranged in a mesh-like or finger electrode configuration, being likewise in contact with the liquid crystal medium; a third electrode is spaced by a dielectric medium from the second electrode, such third electrode being in either orthogonal or parallel relationship with the second electrode. Voltages are selectively applied to each of the second and third electrodes such that the stable state of the liquid crystalline layer is changed from the ordered (homeotropic) or clear state, to the disordered (focal conic) or dark state.
