  • SOURCE DRIVING CIRCUIT, DISPLAYER AND CONTROL METHOD THEREOF
    Publication number: 20100001987
    Abstract: A source driving circuit is suitable for a display panel. The source driving circuit of the present invention has a plurality of latches and a plurality of output buffers. Each of the latches is used for respectively receiving a data signal. In addition, all of the latches output the corresponding data signals at different time intervals according to a data output signal. After all of the latches have output the data signals to the corresponding output buffers, all output buffers transmit the data signals to the display panel synchronously.

  • Liquid crystal display device and driving method of the same
    Patent number: 7471275
    Abstract: The invention is directed to a driving method for an LCD device, including conducting two of the gate driving lines respectively controlled by different gate integrated circuits. Then, it is determined that one of the two conducted gate driving lines is applied with the scan signal, according to a first output enabling signal and a second output enabling signal being received. A latch signal is received, wherein during a period at a high logic level of the latch signal, the adjacent source driving lines are shorted.
