  • Publication number: 20080074379
    Abstract: A gate drive circuit of a display device includes a plurality of stages, each stage being coupled to at least one other stage. A current stage among the stages includes a gate section, a carry section, a buffer section, and a reset section. The gate section generates a current gate signal and the carry section generates a current carry signal. The buffer section receives a previous carry signal from a previous stage, and then turns on the gate section and the carry section. The reset section receives a next carry signal from next stages, and then turns off the gate section and the carry section. As the current stage is reset in response to the next carry signal, the function of the gate drive circuit is increased.

  • Publication number: 20070038909
    Abstract: A scan driver drives a display device having a plurality of gate lines transferring scan signals, and a plurality of source lines transferring data signals. The scan driver includes a shift register and a multiple signal applying unit. The shift register includes a plurality of cascade-connected stages, each stage having an output terminal electrically connected to a respective one of the plurality of gate lines. The multiple signal applying unit applies a sub scan signal and a main scan signal. The sub scan signal and the main scan signal sequentially activate each of the plurality of gate lines. Therefore, the scan lines receive the scan signal twice, so that the liquid crystal capacitors electrically connected to the gate lines receive the data voltage twice. As a result, even though the time for charging the liquid crystal capacitors may be reduced, the liquid crystal capacitors may be fully charged to enhance display quality.
