摘要： The invention comprises a stacked color photodisplay apparatus using a photosensitive cholesteric liquid crystalline material on which an image can be optically addressed, retained without degradation for an indefinite period of time, electrically erased and a new image addressed. This is similar to a photographic film except that the photodisplay film can be used over and over again similar to digital display but without the cost of addressing electronics. Included is a device for enhancing the brightness of the image and electrooptical devices for optically writing digital images on the photodisplay. Each cell in the stack can be selectively addressed with a different optical image such as the red, green and blue components of a color digital image.

摘要： 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.

摘要： An electronic writing tablet is composed of one or more layers on which an image is formed and can be selectively erased. One aspect of the invention is a bistable cholesteric writing tablet on which an image is formed while applying writing pressure. The image can be fully erased and new images written on the tablet. In addition, one can selectively erase any or all portions of the written image to restore the original background color. Another aspect of the invention is a multi-color stacked writing tablet in which a color of an image is selected (usually by applying a suitable voltage) while applying writing pressure using an instrument such as an untethered stylus on the surface of the tablet. The writing tablet includes at least two or three stacked layers of bistable cholesteric liquid crystal material. Selected colors can be additively mixed to achieve intermediate colors as desired. The image can be fully erased and new images written on the tablet. In addition, one can selectively erase any or all portions of the written image to restore the original background color.

摘要： The present invention is directed to a cholesteric liquid crystal display that includes a homogeneous alignment surface effective to provide increased brightness, low focal conic reflectance and/or reflected light treat is to a significant degree circularly polarized. The homogeneous alignment surface substantially homogeneously aligns the liquid crystal director adjacent thereto. The homogeneous alignment surface may be disposed on one or both sides of a cell of the display. In the case of a cell in which the homogeneous alignment surface is disposed on only one side, the substrate with the inhomogeneous alignment surface may be upstream or downstream of the substrate with the homogeneous alignment surface relative to a direction of incident light. Also included especially in the case of a cell that has the homogeneous alignment surface on both sides is the use of a polarizer to provide very good brightness and low focal conic reflectance. Such a cell may employ an alignment layer material with a high pretilt angle. A stacked display may be produced including at least one cell with at least one homogeneous alignment surface. In particular, a stacked cell display may include a lower cell with two homogeneous alignment surfaces and an upper cell in which the top side has an inhomogeneous alignment surface and the bottom side has a homogeneous alignment surface. The present invention achieves any one or combinations of the above features through the use of the homogeneous alignment surface produced with a predetermined alignment layer material and predetermined alignment conditions. The invention also includes a method of making the inventive display and the stacked inventive display.

摘要： A display device includes a piezoelectric layer. First electrically conductive electrodes are disposed on both sides of the piezoelectric layer. A bistable liquid crystal layer is disposed adjacent the piezoelectric layer. Second electrically conductive electrodes are disposed on both sides of the liquid crystal layer. The liquid crystal layer can be addressed by electrically addressing the piezoelectric layer causing the piezoelectric layer to move into contact with the liquid crystal layer, changing the brightness of pixels of the liquid crystal layer.

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 (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. The display film may interact with components mounted on or laminated to the substrate, including a solar cell, active matrix backplane and electrodes. The display film may be mounted onto flexible or drapable substrates such as fabric and can itself be drapable. Thus, the invention offers substantial flexibility in fabrication and design that has not been previously possible in the display industry.
