  • Patent number: 9450106
    Abstract: Disclosed is a thin film transistor (TFT) of a display apparatus which reduces a leakage current caused by a hump and decreases screen defects. The TFT includes an active layer and a first gate electrode with a gate insulator therebetween, and a source electrode and a drain electrode respectively disposed at both ends of the active layer. The gate electrode branches as a plurality of lines and overlaps the active layer. The active layer includes one or more channel areas between the source electrode and the drain electrode, one or more dummy areas, and a plurality of link areas between the one or more channel areas to connect the one or more channel areas in one pattern. A length of each of the one or more dummy areas extends from an edge of a corresponding channel area.

  • Patent number: 8902210
    Abstract: An LCD device includes dual gate transistors provided to an output portion of the shift register for outputting a gate voltage. As such, the charge/discharge time of the output portion is reduced so the response time of liquid crystal is improved.

  • Patent number: 8879012
    Abstract: An array substrate for a liquid crystal display device and a fabrication method thereof, and a liquid crystal display device having the same are disclosed. The array substrate for a liquid crystal display device and a fabrication method thereof, and a liquid crystal display device having the same according to the present disclosure eliminate optical loss by use of a shielding film that can decrease the optic leakage current to minimize the optic leakage loss, thus it is possible to improve the picture quality.

  • Publication number: 20130177780
    Abstract: Provided is a hot dip plated steel sheet used in automotive materials and a method of manufacturing the same, and more particularly, to a hot dip plated steel sheet having excellent platability and plating adhesiveness in which a steel sheet containing alloying elements forming oxides on a surface of the steel sheet at high temperatures is used as an underlying steel sheet, and a method of manufacturing the same. According to the present invention, a hot dip plated steel sheet having excellent platability and plating adhesiveness is provided, in which a steel sheet containing alloying elements forming oxides on a surface of the steel sheet at high temperatures is used as an underlying steel sheet, and thus, limitations in added amounts of silicon (Si), manganese (Mn), or aluminum (Al) may be mitigated. Therefore, development of new steels may be accelerated.
