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.
