    摘要: A gate driving circuit for driving plural scan lines of a liquid crystal display includes N driving circuit units and a control unit. Each of the N driving circuit units sequentially outputs a driving signal to drive a corresponding scan line of the scan lines. The control unit outputs a positive-phase and an opposite-phase clock signal to control the N driving circuit units. After an Nth driving circuit unit of the N driving circuit units outputs the driving signal, the control unit transmits a control signal to at least one of the N driving circuit units. A method for driving the foregoing gate driving circuit is also disclosed.

    摘要: A common-voltage compensation circuit functions to provide a crosstalk interference suppressing mechanism for use in a liquid crystal display having a liquid-crystal capacitor and a storage capacitor. The compensation circuit includes a buffer for receiving a preliminary common voltage, a current/voltage converter, a high-pass filter and a ripple-voltage inverter. The current/voltage converter is utilized for generating a liquid-crystal capacitor common voltage furnished to the liquid-crystal capacitor according to an output current of the buffer. The high-pass filter performs a high-pass filtering operation on the liquid-crystal capacitor common voltage for extracting a ripple voltage. The ripple-voltage inverter is employed to generate a storage capacitor common voltage furnished to the storage capacitor through performing an inverting operation on the ripple voltage based on the preliminary common voltage. The ripple voltage of the storage capacitor common voltage has a phase opposite to that of the liquid-crystal capacitor common voltage for suppressing crosstalk interference.
