Driving circuit and method for liquid crystal display panel

摘要

A driving circuit and a driving method can drive an LCD panel to display imagines. Storages capacitors of pixels connected with each scanning line are connected with an AC signal source. The AC signal source can vary the potential of its signal in harmony with the polarity inversion of a pixel during a vertical scanning period. Due to a capacitively coupled effect, a coupled voltage induced by the variation in the potential of the signal changes the potential of a pixel electrode so as to speed up the alternation in the electrical field of an LC capacitor.
