  • Patent number: 9323041
    Abstract: This disclosure provides systems, methods and apparatus for dissipating charge buildup within a display element with a conductive layer. The conductive layer is maintained in electrical contact with a fluid within the display element. The fluid, in turn, remains in contact with light modulators within the display elements. Any charge buildup that may be caused by the filling of the fluid during fabrication of the display device, or during operation of the light modulators can be dissipated by the conductive layer. Thus, by dissipating the charge buildup, the conductive layer reduces or eliminates electrostatic forces due to the charge buildup that may affect the operability of the light modulators. The display can include conductive spacers in an active display region of the display and a spacer-free region that allows the substrates to deform while retaining an electrical connection between the conductive layer and the spacers in the active display region.

  • Patent number: 9213181
    Abstract: A display apparatus includes a first substrate, a plurality of microelectromechanical systems (MEMS) light modulators formed from a structural material coupled to the first substrate and a second substrate separated from the first substrate. A plurality of spacers extend from the first substrate to keep the second substrate a minimum distance away from the plurality of light modulators. The spacers include a first polymer layer having a surface in contact with the first substrate, a second polymer layer encapsulating the first polymer layer and a layer of the structural material encapsulating the second polymer layer. The spacers can be used as fluid barriers and configured to surround more than one but less than all of the MEMS light modulators in the display apparatus.

  • Patent number: 9140900
    Abstract: A display for imaging includes an aperture layer and a set of light modulators. The aperture layer includes a light absorbing layer disposed over a light reflecting layer, each layer having a set of apertures defined therein. The light absorbing layer includes light absorbing material suspended in a photosensitive resin. The set of light modulators are for modulating light passing through the apertures defined in the aperture layer.

  • Patent number: 9122047
    Abstract: This disclosure provides systems, methods and apparatus for preventing particles from entering electromechanical systems (EMS) display devices. In one aspect, an apparatus includes a plate, a substrate supporting at least one EMS device, a seal joining the plate and the substrate to define a cavity therebetween and at least one port for receiving a fluid, and a filter disposed between the port and the EMS device. The filter includes elements formed on at least one of a surface of the substrate and a surface of the plate, defining a gap sized to allow the received fluid to pass and to inhibit non-fluidic particles carried in the fluid from the EMS device.

  • Patent number: 8891152
    Abstract: This methods and devices described herein relate to displays and methods of manufacturing cold seal fluid-filled displays, including MEMS. The fluid substantially surrounds the moving components of the MEMS display to reduce the effects of stiction and to improve the optical and electromechanical performance of the display. The invention relates to a method for sealing a MEMS display at a lower temperature such that a vapor bubble does not form only at temperatures about 15° C. to about 20° C. below the seal temperature. In some embodiments, the MEMS display apparatus includes a first substrate, a second substrate separated from the first substrate by a gap and supporting an array of light modulators, a fluid substantially filling the gap, a plurality of spacers within the gap, and a sealing material joining the first substrate to the second substrate.

  • Publication number: 20140267314
    Abstract: This disclosure provides systems, methods and apparatus for a display including a fluid-filled cavity. The display can include a plurality of light modulators, and a viewable portion and a non-viewable portion. A bubble generator can be positioned within the non-viewable portion of the cavity and arranged to form a bubble within the non-viewable portion. The non-viewable portion of the display may include a region in which a bubble or bubbles are generated and allowed to move. The display may include a controller arranged to control the operation of the bubble generator. The display also may include a temperature sensor or pressure sensor arranged to measure the temperature or pressure of the display apparatus. The controller may control the operation of the bubble generator in response to a signal from either the temperature sensor, pressure sensor, or both.
