Abstract
A common voltage modification circuit and a method thereof are provided. The present invention is characterized in that an output voltage is provided to a storage capacitor in each of the pixels in a thin-film transistor liquid crystal display (TFT LCD) based on a predetermined voltage and a common voltage. Wherein a liquid crystal capacitor of each pixel is electrically connected to the common voltage. In addition, the phase and amplitude of the output voltage are same as the phase and amplitude of the common voltage. Finally, the result of subtracting the output voltage from the common voltage is equal to the absolute value of the predetermined voltage.
