Abstract: The invention is an electronic shelf (eShelf). The eShelf uses highly conductive electrodes to solve the long-line addressing problems using very-simple, low-cost manufacturing processes to build very-long, reflective, “no-power”, full-color, liquid crystal displays (LCDs) with perfect image retention. The electronic shelf is composed of an eSheet cholesteric LCD attached to a shelf product sensor pad that can turn a normal store aisle into an interactive, full-color, fun and informative shopping experience. The eShelf is the next generation of in-store smart technology combining product management with customer interaction and advertising. The true success of the eShelf will depend on the countless apps that will run on or interact with the eShelf to help customers make their purchasing decisions. These software applications will allow the eShelf to interact with the customers smart mobile device, such as, a tablet, smartphone, smartwatch, or Google Glass.

Abstract: eSheets create a multitude of different products. One embodiment is a projected capacitive touch sensor created by embedding orthogonal arrays of coated metal wires into the surface of a polymer sheet or onto the back of a projector screen. To increase the capacitance of the electrodes or pixels in the sensor, transparent conductive electrodes can be electrically connected to the wire electrodes. Another embodiment is a reflective, energy-efficient display formed by sandwiching a reflective cholesteric liquid crystal (Ch. LC) material between electroded sheet substrates. The eSheet Ch. LCD is pressure sensitive and can be written on using a finger or stylus. The eSheet Ch. LCD can then be read using the wire electrodes in the eSheet LCD.

Abstract: A sheet in an electronic display is composed of a substrate containing an array of wire electrodes. The wire electrodes are preferably electrically connected to patterned transparent conductive electrode lines. The wire electrodes are used to carry the bulk of the current. The wire electrodes are capable of being extended away from the substrate and connected directly to the printed circuit board. The transparent conductive electrode (TCE) is used to spread the charge or voltage from the wire electrode across the pixel. The TCE is a patterned film and must be at least 50% transparent, and, for most applications, is preferably over 90% transparent. In most applications, the electroded surface of the electroded sheet has to be flattened. Use of a thin polymer substrate yields a light, flexible, rugged sheet that may be curved, bent or rolled.

Abstract: An effective method to create very large electronic displays forms the structure using fiber or tube arrays or electroded sheets containing wire electrodes. The electroded sheets are formed by embedding wire electrodes into the surface of a polymer substrate and electrically connecting a patterned transparent conductive electrode lines to the wires. The wire electrodes are used to carry the bulk of the current and the transparent conductive electrode is used to spread the charge or voltage from the wire electrode across the line of pixels. In most display applications, the electroded surface of the electroded sheet has to be flattened. The electroded sheets may be used to form many different types of displays.

Abstract: A glass-ceramic material which exhibits extremely low (e.g. less than 100 ppm) shrinkage, when exposed to 900° C. for 6 hours, and methods for making such glass-ceramics. The glass-ceramic is cerammed at a sufficiently high temperature and then cooling in a controlled manner, preferably to below the strain point of the resultant material. Using this technique, glass-ceramic materials were fabricated which exhibited dimensional shrinkage comparable to and in some cases even less than that achieved by fused silica substrates, when exposed to high temperature poly-Si processing temperatures (e.g. 900° C. for 6 hours).

Abstract: The invention relates to improved techniques for manufacturing columnar-grained polycrystalline sheets which have particular utility as substrates or wafers for solar cells. The sheet is made from silicon on a setter material which supports the silicon material. The setter material and silicon are subjected to a thermal profile all of which promote columnar growth. The thermal profile sequentially creates a melt region where a thin-film capping layer grows at the top of the silicon, a nucleation region where preferential nucleation occurs at the capping-layer/molten-silicon interface, and then a growth region where both liquid and a growing polycrystalline sheet layer coexist. An annealing region is created where the temperature of the grown polycrystalline silicon sheet layer is controllably reduced to effect stress relief.

Abstract: Rib structures for containing plasma in electronic displays are formed by redrawing glass preform into fiber-like rib components. The rib components are then assembled to form rib/channel structures suitable for use in flat panel displays, such as plasma emissive displays, field emissive displays and plasma addressed liquid crystal displays.

Abstract: A method for forming top gated TFTs directly on a glass surface, wherein the glass surface is first leached adequately to provide a silica-rich boundary area at the glass surface, after which the source-drain semiconductor region is deposited directly onto the glass surface without a barrier layer.
