Abstract:
1. A method for driving a liquid crystal panel comprising: applying a voltage signal, a polarity of which alternates, to pixel electrodes included in the liquid crystal panel, the voltage signal being applied to liquid crystal cells of the liquid crystal panel to control light transmission, the voltage signal being supplied from a data driving unit; applying a common voltage signal, a polarity of which alternates, to a common electrode included in the liquid crystal panel, the common voltage signal and the voltage signal being out of phase, the common voltage signal being supplied from a common electrode driving circuit; and applying a first signal to a transparent electrode included in the liquid crystal panel whenever the common voltage signal is applied to the common electrode, the first signal having the same frequency and amplitude as the common voltage signal, the first signal and the common voltage signal being out of phase with each other, the first signal being supplied from a first signal driving circuit, wherein the liquid crystal panel comprises:
