摘要： A reflective cholesteric display that may be viewed under a wide range of ambient lighting conditions, ranging from complete darkness to bright sunlight. The display includes a chiral nematic liquid crystal material located between first and second substrates, an ambidextrous or bi-directional circular polarizer, a partial mirror, also referred to as a transflector, and a light source. The liquid crystal material includes focal conic and planar textures that are stable in the absence of an electric field. The ambidextrous circular polarizer is located adjacent to one of the substrates that constrain the liquid crystal material. The chiral nematic liquid crystal display may be operated in both a transmissive mode and a reflective mode.

摘要： In order to maintain adequate bond strength of a composite in which a gas barrier coating comprising a clay dispersion and a polymer solution or dispersion of a PVA and/or EVA is positioned between two flexible plastics films using an adhesive, it is necessary that the clay dispersion and the polymer solution or dispersion should be kept separate until shortly before they are to be applied.

摘要： A stacked color liquid crystal display uses shared electrode addressing including a plurality of liquid crystal layers each sandwiched between electrically conductive layers. Adjacent liquid crystal layers share one or two electrode layers located between the adjacent liquid crystal layers. A driving scheme is provided that allows the display to be driven by updating the liquid crystal layers sequentially, concurrently, or some combination of the two. Further, a method of manufacturing the display using a deposition process is also disclosed.

摘要： A liquid crystal display device includes cell wall structure and a chiral nematic liquid crystal material. The cell wall structure and the liquid crystal cooperate to form focal conic and twisted planar textures that are stable in the absence of a field. A device applies an electric field to the liquid crystal for transforming at least a portion of the material to at least one of the focal conic and twisted planar textures. The liquid crystal material has a pitch length effective to reflect radiation having a wavelength in both the visible and the infrared ranges of the electromagnetic spectrum at intensity that is sufficient for viewing by an observer. One liquid crystal material may be disposed in a single region or two or more liquid crystal materials may be used, each in separate regions even without the infrared reflecting layer. One aspect of the invention is directed to a photolithography method for patterning a substrate of the display. The display may also have multicolor capabilities by including separate layers of at least two or three liquid crystal materials that reflect visible light. A full color stacked display may be produced with grey scale capabilities.

摘要： An electronic display includes electrically conductive layers. At least one active layer is disposed between adjacent electrically conductive layers. The active layer includes cholesteric liquid crystal material. The display includes a front transparent substrate behind which the electrically conductive layers are disposed. A back component is disposed at a back of the display below the active layer. At least one patterned layer is disposed at at least one of the following locations: on, in or near the front substrate and as an interlayer between the front substrate and the back component. The patterned layer is opaque or semitransparent. Electronic circuitry applies a voltage to the conductive layers that enables at least one of erasing or writing of the active layer. The active layer and the patterned layer cooperate to produce an image on the display.

摘要： A unique class of chiral additive materials is disclosed for use in cholesteric displays that possess a helical twist power substantially independent of temperature. The additives have a solubility and a helical twist power large enough to be used as a single chiral component with little dilution of the physical properties of the nematic liquid crystal host mixture. The chiral additives may be used in combination with non-chiral additives to provide a helical twisting power substantially independent of temperature suitable for cholesteric displays.

摘要： An electronic display includes electrically conductive layers. An active layer is disposed between adjacent electrically conductive layers. The active layer includes cholesteric liquid crystal material. At least one transparent front substrate is disposed adjacent one of the electrically conductive layers near a front of the display. A semitransparent back layer absorbs light that passes through the active layer, reflects grey light or light of a color and is light transmitting. Electronic circuitry applies a voltage to the conductive layers that enables at least one of erasing or writing of the active layer.
