摘要： A reimagable medium and a method for “writing” to a reimagable medium are disclosed. The reimagable medium includes a liquid crystal layer, one or more photochromic layers and an electric field generating apparatus. The electric field generating apparatus supplies voltage levels across the liquid crystal layer causing the liquid crystal layer to transfer between a white and a transparent state. The photochromic layers transfer to a colored state when illuminated by ultraviolet light and to a transparent state when illuminated by visible light. Each of the layers maintains their present states when voltage or illumination below corresponding thresholds is supplied. The reimagable medium is flexible and may maintain an image “written” to it until the paper is rewritten. The paper may be attached to a colored substrate if an additional color is to be displayed.

摘要： A cholesteric display including a liquid crystalline mixture having a dipolar dopant dissolved in the liquid crystalline mixture and the resulting mixture is reflecting light in the visible range of the spectrum when in planar state. In accordance with another aspect, a process includes forming a composition with a dipolar molecule to result in a liquid crystal dipolar dopant, and liquid crystal is added to the composition. In accordance with still another aspect, a device includes a liquid crystal composition includes a cholesteric liquid and a dipolar dopant. The liquid crystal composition is switchable between a focal-conic state and a planar state in the presence of an electric field and is stable in the respective state when the electric field is removed.

摘要： A display member having improved optical contrast and brightness. The display member includes bichromal capsules, an absorptive layer, an adhesive layer, a substrate and a top layer. The bichromal capsules form a close-packed monolayer configuration positioned on the absorptive layer. The adhesive layer is adjacent to the absorptive layer. The absorptive layer is formed on the substrate. The top layer is formed adjacent the adhesive layer. A method for producing a display member with high optical contrast and brightness. The method includes forming an absorptive layer on a substrate. A close-packed monolayer configuration of bichromal capsules is formed on the absorptive layer by exposing the absorptive layer to a plurality of bichromal capsules. A top layer is formed adjacent the adhesive layer.

摘要： An image forming method composed of: (a) providing a reimageable medium composed of a substrate and a photochromic material, wherein the medium is capable of exhibiting a color contrast and an absence of the color contrast; (b) exposing the medium to an imaging light corresponding to a predetermined image to result in an exposed region and a non-exposed region, wherein the color contrast is present between the exposed region and the non-exposed region to allow a temporary image corresponding to the predetermined image to be visible for a visible time; (c) subjecting the temporary image to an indoor ambient condition for an image erasing time to change the color contrast to the absence of the color contrast to erase the temporary image without using an image erasure device; and (d) optionally repeating procedures (b) and (c) a number of times to result in the medium undergoing a number of additional cycles of temporary image formation and temporary image erasure.
