    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.
