  • Patent number: 8416359
    Abstract: Array substrates for liquid crystal display (LCD) devices are formed on a substrate with first and second gate lines crossing a data line to define first and second pixel regions. A thin film transistor includes a source electrode and a drain electrode. A metal pattern overlaps a common line and makes up a portion of the drain electrode. A passivation layer is disposed on the source and drain electrodes and on the metal pattern. A first pixel electrode is connected to the metal pattern and a common electrode is connected to the common line. Various repair patterns are formed to define one or more repairing portions that enable connection of the drain electrode or metal pattern to a second pixel electrode of the second pixel region if the cut line is cut in the event the first pixel electrode fails to display an image.

  • Patent number: 8417070
    Abstract: A metal-semiconductor-metal (MSM) device couples light from an optical mode in a waveguide to a surface plasmon polarition (SPP) mode on an electrode surface of the MSM device. Once in an SPP mode, the absorption of light in the semiconductor can take place in a very small area. This may allow for a shrinking of the active detector area and allow for low capacitance, very short transit distance for the electrical carriers and allow for very low voltage devices and/or very high frequency.

  • Patent number: 8376629
    Abstract: A fiber optic connector assembly and method employing one or more fiber movement supports. The one or more fiber movement supports are each disposed around one or more optical fibers and are configured to inhibit kinks or sharp bends from occurring in the one or more optical fibers. The fiber movement support is more rigid than an optical fiber. Thus, when a force is exerted on an optical fiber in a direction angled to the axis of the optical fiber, the force is directed to the fiber movement support. The fiber movement support translates the non-axial force in a direction toward the axis of the optical fiber. This causes the optical fiber to be pushed back towards the fiber optic cable instead of the kinking or bending the optical fiber, thus avoiding or reducing high insertion losses resulting from bending of the optical fiber.

  • Patent number: 8373821
    Abstract: A front light guide panel including a plurality of embedded surface features is provided. The front light panel is configured to deliver uniform illumination from an artificial light source disposed at one side of the font light panel to an array of display elements located behind the front light guide while allowing for the option of illumination from ambient lighting transmitted through the light guide panel. The surface embedded surface relief features create air pockets within the light guide panel. Light incident on the side surface of the light guide propagates though the light guide until it strikes an air/light material guide interface at one on the air pockets. The light is then turned by total internal reflection through a large angle such that it exits an output face disposed in front of the array of display elements.

  • Patent number: 8363174
    Abstract: The present invention relates to the removal of ion contaminations from liquid crystal layers in liquid crystal display devices. The ions are removed by means of so called ion pumping, which utilizes the anisotropic viscosity of liquid crystals. The ions are pumped up and down in the liquid crystal layer by means of an alternating electric filed. The alternating electric field simultaneously alters the alignment of directors in the liquid crystal. The viscosity in the liquid crystal is related to the director directions, and the ions are thereby moved in non-closed trajectories. The inventive ion pumping can be further improved using an asymmetric or biased alternating electric field.
