Abstract
An exemplary liquid crystal display device includes a liquid crystal panel, a common voltage generator and a scanning voltage regenerator. The liquid crystal panel includes a plurality of pixel regions formed in a matrix form. Each pixel region includes a thin-film transistor and a storage capacitor. The storage capacitor includes a pixel electrode and a storage electrode facing the pixel electrode. The common voltage generator is configured for providing a common voltage to the storage electrode. The scanning voltage regenerator is configured for receiving a feedback common voltage from the storage electrode and generating a regenerated scanning voltage for driving the thin-film transistor according to the feedback common voltage.
