  • Patent number: 8098431
    Abstract: Various embodiments of the invention relate to methods and systems for generating the color white in displays created from interferometric modulators and more specifically, to the generation of the color white through the use of reflected light at two wavelengths. In one embodiment, a display device displays the color white. The color white is generated by reflecting light from two pluralities of interferometric modulator types. The first modulator type reflects colored light at a specific wavelength. The second modulator type reflects colored light selected to be at a wavelength complementary to the first. The combined light reflected from the two types appears white in the display.

  • Patent number: 7935555
    Abstract: A method of sealing a microelectromechanical system (MEMS) device from ambient conditions is described. The MEMS device is formed on a substrate and a substantially hermetic seal is formed as part of the MEMS device manufacturing process. The method may include forming a metal seal on the substrate proximate to a perimeter of the MEMS device using a method such as photolithography. The metal seal is formed on the substrate while the MEMS device retains a sacrificial layer between conductive members of MEMS elements, and the sacrificial layer is removed after formation of the seal and prior to attachment of a backplane.

  • Patent number: 7843410
    Abstract: One embodiment includes a display of interferometric modulators having a configurable resolution characteristic. Selected rows and/or columns are interconnected via a switch. The switch can include a fuse, antifuse, transistor, and the like. Depending on a desired resolution for a display, the switches can be placed in an “open” or “closed” state. Advantageously, using the switches, a display can readily be configured for differing modes of resolution. Furthermore, using the switches, a display can be configured to electrically connect certain rows or columns in the display such that the connected rows or columns can be driven simultaneously by a common voltage source.
