  • Patent number: 9343030
    Abstract: A gate driving circuit includes N stages (where N is a natural number greater than or equal to 2). The N stages are cascaded, and each of the N stages has a gate line connected thereto. A first stage group includes k stages of the N stages (where k is a natural number less than N), and the first stage group outputs a first output signal in response to a start signal. A second stage group (including N?k stages) generates a second output signal in response to the first output signal and outputs the second output signal to a corresponding gate line. The first stage group includes a first buffer and a second buffer, each of which receives the start signal. A size of the first buffer is smaller than a size of the second buffer.

  • Publication number: 20150244010
    Abstract: Disclosed is a technique of diagnosing a state of a fuel cell system. The technique includes configuring a processor to calculate a duty ratio and an average output current, based on real-time driving data for a preset driving period, during operation of a fuel cell vehicle; obtain a reference current value from the calculated duty ratio and the calculated average output current; and determine a state of a fuel cell system by choosing a state graph corresponding to the obtained reference current value among a plurality of state graphs which vary depending on each reference current value.

  • Patent number: 8773626
    Abstract: A display substrate includes a gate line, a data line and a pixel electrode. The gate line is extended in a first direction on a base substrate. The data line is extended in a second direction crossing to the first direction. The pixel electrode is disposed on a pixel area of the base substrate. The pixel electrode includes a first sub-electrode and a second sub-electrode spaced apart by an opening portion, and receives a voltage having a same polarity. The opening portion includes a straight line portion extended in the first direction, a diagonal line portion extended in a third direction crossing the first and second directions, and a protrusion portion disposed in a length direction of the straight line portion at a portion of the pixel electrode where the straight line portion and the diagonal line portion meet.

  • Publication number: 20140146254
    Abstract: A display substrate has first and second conductive layers separated from one another by an insulation layer. The first and second conductive layers are used to integrally form on the display substrate, pixel units in a relatively central display area of the substrate and integrated gate driving circuitry as well as associated wirings thereof in one or more peripheral areas. The first and second conductive layers are covered by a first protection layer made of a first electrically insulative material. A second and supplementing protection layer is provided on top of the first protection layer. The supplementing protection layer (buffer layer) is formed of a material different from that of the first protection layer so as to provide supplemental resistance against corrosive chemical agents and supplemental resistance against formation of cracks.
