摘要： A cholesteric liquid crystal writing board display device includes a plurality of cholesteric liquid crystal writing tablets and a front cover layer extending over the cholesteric liquid crystal writing tablets. The cholesteric liquid crystal writing tablets are tiled together by the front cover layer such that the writing board display device appears nearly seamless. Or, the writing tablets can be spaced apart from each other.

摘要： This disclosure features an electronic display with overlayed electronic skin. The display includes an outer transparent display surface and can be placed in a dark state or in a bright state. The skin overlays the outer display surface and includes an electro-optic layer. Transparent electrically conductive layers are disposed on each side of the electro-optic layer. Electronic circuitry applies voltages to the electrically conductive layers enabling the electro-optic material of the electronic skin to be placed into a substantially transparent state and a reflective state. Images or colors can be displayed on the electronic skin while portions of the electronic skin are in the reflective state and light passing through the electronic skin is absorbed by the display in the dark state. When the display is in the bright state images or colors can be displayed on the display that can be seen through the electronic skin.

摘要： One aspect of the invention is a bistable cholesteric writing tablet on which an image is formed by applying a suitable voltage while applying writing pressure, which results in a focal conic texture in a reduced gap region of the active layer while not changing the texture of the unreduced gap region of the active layer (e.g., a written portion being in a focal conic texture on a background in the planar texture). Another aspect of the invention is a multi-color stacked writing tablet in which a color of an image is selected 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 erased and new images written on the tablet. Gray scale achieved by varying the applied voltage during writing or the writing pressure in some cases, enables the writing tablet to produce a broad range of colors. The writing device is suitable for many applications such as a toy, sketch pad, erasable signage, tags or a large writing board without the mess of chalk or ink.

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： Electronic color changing artificial nails comprise a polymer layer in a general shape of a human natural nail, bistable electro-optic material and a ledge on which display electrodes are disposed located at a tip of the artificial nail. Once the artificial nail is attached to the natural nail, the artificial nail can be updated by simply plugging the tip into a separate electronic color changing device which is used to set the color of the nail to whatever the user desires.

摘要： Electrooptical displays require conductors on both sides of the liquid crystal thin film. The two conductors face opposite sides of the display. The cost of electrically connecting to these displays can be decreased by having the conductors of the display all face the same side of the display. This invention includes a technique to allow both conductors to face the same side of the display.
