  • Patent number: 9436324
    Abstract: A touch-sensitive display includes first electrodes and second electrodes coupled to a first controller to detect touches by self-capacitance touch sensing. The touch-sensitive display also includes third electrodes coupled to a second controller to detect touches by mutual-capacitance touch sensing utilizing the third electrodes and the second electrodes. The first electrodes are different from the third electrodes.

  • Publication number: 20150062130
    Abstract: Devices, methods, and non-transitory media for controlling a microdisplay are described. A device includes a microdisplay; and a display controller for the microdisplay. The display controller includes at least one frame buffer configured to store a multi-frame animation; and control logic configured to control operation of the microdisplay in response to signals generated by a host controller of the mobile electronic device, the control logic comprising executable instructions to display the animation on the microdisplay by: commencing display of the animation when signals representing a start command generated by the host controller are detected, and repeatedly displaying the animation in the absence of detecting further signals representing commands generated by the host controller.

  • Publication number: 20140071384
    Abstract: An electrostatic discharge structure for a light transmissive panel and method of fabricating same. A light transmissive conductive area extends across a light transmissive panel, where the light transmissive conductive area is separate from a static discharge potential. At least one conductive area spark gap point, conductively coupled to an outside perimeter of the light transmissive conductive area. At least one discharge spark gap point is conductively coupled to a static discharge potential, where each discharge spark gap point is located in proximity to a respective conductive area spark gap point so as to support electrostatic breakdown at less than a determined voltage between the each discharge spark gap point and the respective conductive area spark gap point.
