  • Patent number: 9332408
    Abstract: A method for routing calls between a third party telecommunications device (“TD”) and a subscriber TD associated with a primary service and a second line service (“SLS”) involves associating the SLS number of the subscriber, the primary number of the subscriber and the primary number of a third party via a common relationship number. Calls directed from a third party to the SLS number of a subscriber are routed to an SLS platform and redirected to the subscriber TD. Calls directed from the subscriber TD to the third party use the relationship number to route the call to the SLS platform. The combination of the SLS number and the relationship number identifies the third party calling number for call completion. Calls can be directed to and from an SLS number of a subscriber TD without having to coordinate the provisioning of a call through the subscriber's primary service provider.

  • 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.

  • Publication number: 20160086529
    Abstract: This disclosure provides systems, methods and apparatus for reducing flicker in display devices. In some image formation processes, a controller can form an image by utilizing a set of color subfields in displaying subframes associated with each of the color subfields. In some implementations, the controller may determine whether to divide or split the display of certain subframes based on environmental factors such as ambient light with or without concern for flicker. In some implementations, the controller may determine to divide or split the display of an x-channel subframe based on the ambient light. The controller can monitor the ambient light levels via an ambient light sensor, and compare the ambient light level to an ambient light threshold. If the ambient light levels go below the ambient light threshold, the controller can employ subframe division or splitting.

  • Patent number: 9291813
    Abstract: Systems and methods for a display having an array of pixels, a substrate, and a control matrix formed on the substrate are described. The array of pixels includes mechanical light modulators that can be referred to as micro-electro-mechanical or MEMS light modulators. The MEMS light modulators may be shutter-based light modulators, and an array of apertures may be formed on the substrate corresponding spatially to the shutters in the array of shutter-based light modulators. Each modulator is configured to be driven from a-light-blocking state to a-light-transmissive state through a movement direction. The array of light modulators are arranged to reduce the correlations in movement directions of neighboring pixels, thereby reducing the amplitude of acoustic emissions from the display.

  • Publication number: 20160077329
    Abstract: In one innovative aspect of the disclosure, a method includes patterning a first region and a first portion of a second region of a substrate using a first reticle. The method also includes patterning the second region and a first portion of the first region using a second reticle. The method additionally includes forming a first array of first patterned elements based on the patterning by the first reticle, and forming a second array of second patterned elements based on the patterning by the second reticle. In some implementations, each of the first and the second arrays are incomplete in each of the first portions. However, the first patterned elements in the first portion of the second region are complementary to the second patterned elements in the first portion of the second region. Similarly, the first patterned elements in the first portion of the first region are complementary to the second patterned elements in the first portion of the first region.

  • Publication number: 20160055788
    Abstract: A display includes pixels and a controller. The controller can cause the pixels to generate colors corresponding to an image frame. The controller can cause the display to display the image frame using sets of subframe images corresponding to contributing colors according to a field sequential color (FSC) image formation process. The contributing colors include component colors and at least one composite color, which is substantially a combination of at least two component colors. A greater number of subframe images corresponding to a first component color can be displayed relative to a number of subframe images corresponding to another component color. The display can be configured to output a given luminance of a contributing color for a first pixel by generating a first set of pixel states and output the same luminance of the contributing color for a second pixel by generating a second, different set of pixel states.
