摘要： A light modulating apparatus containing cholesteric liquid crystals capable of indefinite zero field retention of optical images, including full color and complete gray scale capability, is described. This invention is predicated on establishment of zero field multistable liquid crystal domains representing a continuous distribution of states ranging from the highly reflective planar to the light-scattering focal-conic structures. The zero field multistable domain structure stability is achieved by controlling solid surface-liquid crystal boundary interactions to provide essential equalization of the total system energy of each of the domain structures. This is the first time this equalization, and thus zero field multistability, has been achieved without the use of a polymer gel addition to create rigid polydomains in the liquid crystal mix. The establishment of a particular domain structure, and thus the degree of light reflection or scattering by individual display pixels, is controlled using either a single relatively long voltage pulse or a number of shorter duration successive voltage pulses. The zero field multistability achieved is remarkably stable against both mechanical shocks and thermal variations. Because these displays eliminate the need for backlighting and image refreshing energy input, they represent ultra low power consumption devices ideal for use with portable display systems. Because these displays also eliminate the need for polarizers, analyzers, retarder and color filters, they are ultra thin and particularly well suited for use in ultra large (i.e., billboard) displays using a building block approach which retains total spatial integrity. These displays can also be fabricated as flexible all-plastic units again utilizing the overall thinness of these devices.

摘要： A method and system for delivering a television display in a very thin cabinet is presented. The reduction of cabinet depth is achieved by the use of suitable optics to create an image ray that is full screen width but greatly reduced in the vertical direction. This beam is then directed at a very shallow oblique angle into the viewing screen system, which allows the viewer to observe the picture or display in its proper proportions.

摘要： Disclosed are various reverse-mode direct-view liquid crystal displays employing a liquid crystal having a characteristic wavelength in the non-visible spectrum, including reflective, transmissive and reflective-transmissive mode displays. In accordance with the principles disclosed, a direct-view liquid crystal display (LCD) includes a front substantially transparent substrate, a rear substrate, and a controllable cholesteric liquid crystal (CLC) disposed between the front and rear substrates and having a characteristic wavelength to reflect non-visible spectrum; the portions of the controllable CLC can selectively exhibit a planar state or a focal-conic state, the portions of the CLC in the planar state appearing dark, and the portions of the CLC in the focal-conic state appearing bright, to an observer of the LCD. The reflective, transmissive and reflective-transmissive mode displays are derived by further combinations with linear and/or circular polarizers, reflective mirrors and/or transmissive/reflective mirrors, and a source of visible light.
