  • Publication number: 20160291427
    Abstract: A display device includes: a gate transmission wiring; a gate insulating layer disposed on the gate transmission wiring; and a pixel electrode and a data transmission wiring that are disposed on the gate insulating layer. When a gate signal voltage is applied to the gate transmission wiring, the gate transmission wiring may serve as a gate electrode that activates a semiconductor layer. In addition, when such a gate signal voltage is not applied thereto, the gate transmission wiring may form an electric field by a voltage difference between the gate transmission wiring and the pixel electrode, to thereby control a liquid crystal layer.

  • Publication number: 20160170198
    Abstract: An electrowetting display device includes first and second barrier layers which cover first and second electrodes. The electrowetting display device includes a first base substrate which faces a second base substrate, the first electrode on the first base substrate, the first barrier layer which covers the first electrode, the second electrode on the second base substrate, the second barrier layer which covers the second electrode, a barrier wall between the first base substrate and the second base substrate, and an electrowetting layer between the first base substrate and the second base substrate. The barrier wall defines a pixel area corresponding to the first electrode, and the electrowetting layer is in the pixel area. The electrowetting layer includes a polar fluid and a non-polar fluid which are separated from each other.

  • Patent number: 9128337
    Abstract: A display apparatus includes a display panel, and at least one flexible printed circuit board connected to the display panel. The display panel includes signal lines, pixels connected to the signal lines, and contact pads provided at one end of the signal lines. The flexible printed circuit board includes a fan-out part including a plurality of connection lines corresponding to the contact pads in a one-to-one correspondence, overlapping with the contact pads and connected to the contact pads, and a driving driver connected to the connection lines, the driving driver applying a driving signal to the pixels.

  • Publication number: 20030028503
    Abstract: A spatial knowledge base approach for the automatic extraction of metadata 116 from electronic documents 100. The electronic document 100 is converted to a substantially format invariant data file 104 by an intermediate language conversion element 102. Spatial layout facts 108 are extracted and combined with spatial layout rules 114 from a knowledge engineer 112 in a spatial metadata-reasoning element 110 to provide the metadata 116. The invention is based on mimicking the visual and spatial knowledge that humans make use of when reading a document.
