Abstract: A photodisplay device in which an optically addressed image can be viewed indefinitely, erased and readdressed with a new image is disclosed. Optically responsive reversible photochiral materials are incorporated into a bistable cholesteric liquid crystal in an electrooptic display cell. A high resolution image exposed on the cell is fixed by a low voltage pulse to unpatterned electrodes and can be, at a later time, erased with a high voltage pulse.

Abstract: 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 (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, insulation layers, and protective layers. The liquid crystal layer 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.

Abstract: The present invention enables a user of a portable electronic communications device such as a cell phone to view information on a larger remote reflective cholesteric display. The portable communications device may connect with the remote display by wire or wirelessly. The remote display is separate from the portable communications device but can interact with it. The remote display receives and/or receives and sends information relative to the portable communications device. This information can include e-mail text and graphics. The remote display, being a bistable cholesteric liquid crystal display, possesses low power requirements unmatched by other display technologies.

Abstract: A flexible liquid crystal display is provided wherein an addressable liquid crystal layer is disposed on a single flexible substrate so that the display itself will exhibit flexibility. The substrate is preferably a flexible non-transparent material and more preferably a drapable material such as fabric.
