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： 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： The production of liquid crystal displays (LCDS) on plastic substrates is desirable over glass substrates so that the finished product is thinner, lighter, and more robust. Plastic substrates can enable the use of new and different processing techniques which are not possible on glass such as roll-to-roll processing. This invention discusses an advancement which is laser cutting a plastic substrate and display layer. One aspect of the invention is laser cutting and welding together two or more plastic substrates and LCD layer therebetween from a larger sheet or roll of plastic LCDs.

摘要： The invention features electronic skin including an active layer formed of bistable cholesteric liquid crystal material and articles comprising the skin, the electronic skin having uniform gray scale reflectivity. Also featured is method for producing suitable reduction pulses that will provide a display (e.g., the electronic skin) with uniform gray scale reflectivity. Reduction pulses of narrow width are used to create uniform levels of gray in the electronic skin to overcome display imperfections that cause discontinuity in the gray scale reflectivity.
