Abstract: The present invention relates to a thin, layered, variable label structure with built-in electronic functionality. The display and/or other functional elements in the structure may be formed by printing processes. The label structure includes a thin, layered structure with an active display, comprising a base layer and a cover layer of material and a display component situated between the base layer and the cover layer. The display is formed with a layer of electrochromic ink and a pair of spaced apart electrodes. The cover layer includes a window to allow for the layer of electrochromic ink to be visible through the cover layer. The label also is configured to respond to an actuating event by completing an electrical connection between a power source and the pair of spaced apart electrodes of the display component, thereby causing the display to change its appearance.

Abstract: The present invention incorporates electronic components into an electronic core structure that may be readily hot laminated by existing processes. The structure may include multiple desired electronic components, such as a display, battery or other power source, integrated circuits, switches, magnetic stripe emulator, antenna, smart chips or other input devices. The structure includes laminated buffer layers to bridge layers and compensate for variation in electronic component dimensions. The structure may also incorporate battery packaging as part of the core layer structure and use printed electronic circuitry as part of the electronic core layers to impart the desired characteristics. A variety of components may be incorporated in the structure.

Abstract: A metal-plated copperless substrate for an electrochromic display. The display includes the substrate in the form of a backplane whereon circuitry of less than about 1 micron in thickness is patterned from the copperless metal. A transparent frontplane is coupled to the substrate with an electro-active ink material therebetween through which pixels may be activated to form an image for the display.

Abstract: The invention is a display device comprising a solid top transparent, charge conducting material, positioned below the transparent solid material is an active layer comprising an electrochromic material and an electrolyte, and positioned below the active layer is a working electrode and a counter-electrode arranged to be isolated from one another, wherein the distance between the working and the counter electrode is greater than two times the thickness of the active layer between the electrode and the conductive material.

Abstract: The present invention relates to a composition and to a display device having the composition positioned between electrodes. The composition contains: (a) a compound that undergoes a reversible redox reaction to generate a pH gradient between the two electrodes, (b) an indicator dye, (c) a charge transport material, and optionally, (d) a matrix material and (e) an opacifier, and (f) secondary redox couple wherein components (a), (b), and (c) are different from one another and the standard reduction potential of component (a) is less than the standard reduction potential for the other components. Depending on the electric field present between the electrodes, a display image may be generated.
