DRAPABLE LIQUID CRYSTAL TRANSFER DISPLAY FILMS

摘要

The present invention relates to a display film that may be transferred by lamination or otherwise onto a substrate. The display film is formed of a stack of layers that can include different types, arrangements, and functionality within the stack depending upon factors including the characteristics of the substrate (32) (e.g. upper or lower, transparent or opaque, substrates) and addressing of the display (e.g., active or passive matrix, electrical or optical addressing}. The layers of the stacked display film include one or more electrode layers and one or more liquid crystal layers and in addition, may include various combinations of an adhesive layer, preparation layer, casting layer, light absorbing layer (16), insulation layers (22) and protective layers. The liquid crystal layer (18) can include cholesteric or other liquid crystal material. The liquid crystal layer can be a dispersion of liquid crystal in a polymer matrix formed by a variety of techniques.
