  • Publication number: 20130176518
    Abstract: Two-sided, back-to-back displays are formed by sealing the backplates of two displays against one another. Mechanical parameters of the backplates, e.g., stiffness and strength, do not meet the requirements for standalone one-sided displays which are otherwise similar to the two displays. However, when sealed against one another, the backplates reinforce each other to meet or exceed the requirements for both one-sided and two-sided displays. The presence of backplates on each of the constituent one-sided displays allows one or both of those displays to be individually tested, thereby increasing the production yield of the back-to-back displays. The display elements of the displays can comprise interferometric modulators.

  • Patent number: 8391010
    Abstract: A thin portable electronic device with a display is described. The components of the electronic device can be arranged in stacked layers within an external housing where each of the stacked layers is located at a different height relative to the thickness of the device. One of the stacked layers can be internal metal frame. The internal metal frame can be configured to act as a heat spreader for heat generating components located in layers adjacent to the internal frame. Further, the internal metal frame can be configured to add to the overall structural stiffness of the device. In addition, the internal metal frame can be configured to provide attachment points for device components, such as the display, so that the device components can be coupled to the external housing via the internal metal frame.

  • Patent number: 8362699
    Abstract: Embodiments of the invention provide for large arrays of microcavity plasma devices that can be made inexpensively, and can produce large area but thin displays or lighting sources Interwoven metal wire mesh, such as interwoven Al mesh, consists of two sets of wires which are interwoven in such a way that the two wire sets cross each other, typically at ?ght angles (90 degrees) although other patterns are also available Fabrication is accomplished with a simple and inexpensive wet chemical etching process The wires in each set are spaced from one another such that the finished mesh forms an array of openings that can be, for example, square, rectangular or diamond-shaped The size of the openings or microcavities is a function of the diameter of the wires in the mesh and the spacing between the wires in the mesh used to form the array of microcavity plasma devices.
