Abstract
Official abstract text for this publication.
A liquid crystal display having common voltage compensation mechanism includes a liquid-crystal capacitor common electrode for receiving a liquid-crystal capacitor common voltage, a storage capacitor common electrode for receiving a storage capacitor common voltage, a common voltage generator for providing the liquid-crystal capacitor common voltage according to a preliminary common voltage, a common voltage compensation circuit electrically connected to the liquid-crystal capacitor common electrode and the storage capacitor common electrode, and a timing controller electrically connected to the common voltage compensation circuit. The common voltage compensation circuit is utilized for generating the storage capacitor common voltage through performing a ripple inverting operation according to the liquid-crystal capacitor common voltage, the preliminary common voltage and a compensation control signal. The timing controller is employed to analyze an image input signal for generating the compensation control signal.
