  • Patent number: 10185200
    Abstract: A thin border display for an electronic device may comprise an optical assembly that includes a support frame and an electrophoretic display (EPD) structure attached to the support frame in a manner that allows for the display of the electronic device to exhibit a “thin border” or “borderless” look at a periphery of the electronic device. A portion of the EPD structure may at least partly curve around a curved portion of the support frame, the curved portion of the support frame being near the periphery of the support frame. In some embodiments, the EPD structure includes a transparent protective substrate disposed on a rear surface of a flexible backplane substrate within the flat outer region where a driver chip is disposed on a front surface of the flexible backplane substrate. The transparent protective substrate protects the driver chip attachment from being damaged during manufacture.

  • Patent number: 10120515
    Abstract: Electronic devices having a display stack that includes LED light sources combined with at least one other component layer are described. In some instances, the LED light sources are coupled to a dedicated touch sensor circuit layer, which removes an entire layer from the display stack. The touch sensor circuit layer can be installed with an addition portion of flexible printed circuitry extending the length of a lightguide and the LEDs can be installed on that flex. In other instances, particularly when the touch sensor layer is deposited directly on the interior surface of the cover glass, the LEDs can also be mounted to the glass itself, thereby potentially eliminating two layers from the display stack.

  • Publication number: 20170293194
    Abstract: An electronic device with a flexible display subassembly is provided. The display stack may use two layers of adhesives having different elastic properties to improve mechanical impact resistance, with a first adhesive layer made of a viscoelastic material and a second adhesive layer having a low modulus of elasticity. The display stack may also include a hot melt protective sheet (HMPS) covering the display subassembly. The HMPS may be wrapped around the two side edges of a rigid substrate to attach directly to the substrate, thereby aiding in the adhesion of the display stack to the substrate. The display stack may also includes a patterned back protective sheet in which the protective backing layer is removed along the curved portions of the display stack.

  • Patent number: 9773474
    Abstract: A content item to be displayed via a display of an electronic device may be associated with a first set of grey values or a set of color values. The electronic device may generate, maintain, or at least have access to one or more mappings that map the set of color values and/or the first set of grey values to a second set of grey values. Based on the one or more mappings, the electronic device may convert a color value of the set of color values or a first grey value of the first set of grey values to a second grey value of the second set of grey values. The content item may then be displayed utilizing the second grey value.

  • Patent number: 9595240
    Abstract: Techniques for adjusting a brightness of a front that lights a display of an electronic device in response to determining that the display is going to perform an update. Typically, page updates on certain types of displays, such as electronic paper displays, result in a relatively large but rapid change in brightness. Therefore, by increasing the brightness during the relatively dark portion of the update (e.g., when some, a majority, or all of the pixels are in the black state) and then decreasing the brightness back to its initial state upon completion of the update, the overall brightness perceived by the user remains more uniform. Increasing the uniformity of this perceived brightness in turn decreases the jarring affect of the flashing update and increases the experience of the user.

  • Patent number: 9564104
    Abstract: Techniques are presented for adjusting a brightness of a front light that illuminates a display of an electronic device. Typically, page updates on certain types of displays, such as electronic paper displays, result in a relatively large but rapid change in brightness. Therefore, by adjusting the brightness of the front light during the update (e.g., when some, a majority, or all of the pixels are in the white state) and then adjusting the brightness back to another state upon or near completion of the update, the overall brightness perceived by the user remains more uniform. Increasing the uniformity of this perceived brightness in turn decreases the jarring effect of an update and increases the experience of the user.

  • Publication number: 20160261457
    Abstract: Homes, enterprise establishments, and other facilities often have routing devices that route traffic to locally connected client devices. A routing device may be connected to an external network (e.g., the internet) through a bridging device, such as an outdoor unit that receives network connectivity through a cellular backhaul connection. If the bridging device's backhaul connection temporarily fails (e.g., due to radio link failure), a public IP address associated with the bridging device and the routing device may change upon recovery of the backhaul connection. If the routing device is not aware of the changed public IP address, subsequent communications between the routing device and the external network may fail. Disclosed are systems and methods for recovering from connectivity failure when using bridging devices to provide network connectivity.

  • Publication number: 20160192403
    Abstract: A method, an apparatus, and a computer program product for communication in a network. The apparatus sends a multicast message to a network device. The multicast message facilitates discovery of an unknown IP address of the network device. The apparatus determines whether a first response message is received from the network device in response to the multicast message and determines the IP address of the network device from the first response message when the first response message is received from the network device. The apparatus establishes a secure connection with the network device using the determined IP address. The apparatus sends a link status check message to the network device to detect a failed end-to-end link between the apparatus and the network device.

  • Publication number: 20160182683
    Abstract: Homes, enterprises, and other facilities often have routers that receive internet connectivity through wired remote network connections, and this connectivity is provided to locally connected client devices. Smart phones and other wireless devices can serve as mobile access points that receive internet connectivity through different remote network connections (e.g., cellular networks). The mobile access points may also service client devices that may be different from those serviced by the routers. When a mobile access point is placed in a facility having a router, the local networks of the mobile access point and the router may be merged. Disclosed are systems and methods for dynamically selecting from multiple host devices (e.g., the router and the mobile access point) to provide internet connectivity for merged networks.
