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.
