  • Patent number: 8786932
    Abstract: The present invention provides for a display device and a method to manufacture the display device. The display device includes: a transparent layer; a coloring electrode; a separator; a second electrode; an electrolyte permeating throughout the display device; and a back layer positioned on the back side of the display. The transparent layer, which has a top surface and a bottom surface, is positioned at the viewer side of the display. The coloring electrode is positioned on the transparent layer bottom surface and includes: a connected conductor system formed from one or more heterogeneous conductive layers and a coloring layer, with the proviso that the heterogeneous conductive layers are not positioned between the transparent layer bottom surface and the coloring layer. The conductor heterogeneity includes variations in one or more of: conductor material composition; conductor layer dimension; conductor layer pattern; conductor layer grid design, and combinations thereof.

  • Publication number: 20110050756
    Abstract: The application describes a device using a display and a method to control the display device in a low power consumption manner. The device may be geared towards disposable use and manufactured using printed electronics techniques. A simple controller system may adapt the state of the device based on type and status of power source(s), or with respect to application specific requirements within the life-cycle of the device.

  • Publication number: 20100220378
    Abstract: A device is disclosed that combines a battery system with an electrochromic system by judicious selection of electrodes and the connection of the appropriate electrodes to generate internal as well as external current flows. This system allows the elimination of a battery component reducing cost and improving manufacturing yield by reduction of the number of parts and number of interconnections. However, the design can be further extended to the combination of a battery system with a sensing system.

  • Publication number: 20100164914
    Abstract: The present invention is a driving circuit for use with reflective display devices. In a preferred embodiment, the display device is a pixilated, active matrix electrochromic device. The inventive circuit includes a sampling capacitor and a plurality of inverters. The sampling circuit quickly stores a data voltage. Addressing of a plurality of electrochromic pixels in an active matrix is thereby accelerated. The inverters are coupled to a relatively high and low power source for quickly driving the electrochromic pixel to the stored data voltage. The circuit of the present invention permits rapid refreshing of electrochromic pixels in an active matrix and achieves color gradients without bleaching and recharging the electrochromic pixel.

  • Publication number: 20080246748
    Abstract: A display having a front plane, a back plane and a border edge. The display includes a color changing cell located behind the front plane of the device and a first and second electrically conducting attachment layer. The color changing cell includes an active color layer having at least one active color area. The active color layer is associated with a first electrically conducting layer which overlaps at least one active color area. The color changing cell also includes a counter layer associated with a second electrically conducting layer. A first electrically conducting attachment layer extends from the active color area and overlaps the first electrically conducting layer. A second electrically conducting attachment layer extends from the counter layer and overlaps the second electrically conducting layer. The display may be coupled to an electronic circuit for use in a variety of applications. The display may also be used to form a device having a plurality of displays.

  • Patent number: 7420727
    Abstract: The present invention is an active matrix electrochromic display architecture where the active components are placed on the backplane of the display, thereby maximizing the viewable pixel area. The cathode of the electrochromic pixel is placed on top of the active components, with respect to the viewer, thereby allowing the active components to be as large as desired while not interfering with the viewable area of the pixel.

  • Patent number: 7403319
    Abstract: An electrochromic device in which specific channel direction for the conduction of ions is implemented. As a result ionic crosstalk between display pixels is greatly reduced and unwanted transient coloration effects are minimized. Further, specific gel, polymer, or ionic liquid solutions can greatly eliminate the corrosive effects associated with the use of electrolyte salt solutions.

  • Publication number: 20070182706
    Abstract: An enhanced reflective layer is described herein for use in a display device. Displays including the enhanced reflective layer are also described. The enhanced reflective layer includes particles that reflect, absorb or emit light with desired properties to enhance the display properties. Use of the enhanced reflective layer in displays allows, among other features, full color active matrix reflective or transflective displays.
