LIQUID CRYSTAL DISPLAY DEVICE AND PIXEL DRIVING METHOD THEREOF

摘要

A pixel driving method for a liquid crystal display device; the liquid crystal display device comprises first level pixels, second level pixels, a first transistor, a second transistor, a third transistor, a first scanning line, a second scanning line, a plurality of data lines, a primary pixel electrode, a secondary pixel electrode and a shared capacitor. The pixel driving method comprises: in a first enabling period, enabling the first scanning line, and charging the primary pixel electrode and secondary pixel electrode of the first level pixels (S402); in a second enabling period, stopping the enabling of the first scanning line so as to reduce the voltage of the primary pixel electrode and secondary pixel electrode of the first level pixels (S404); in a third enabling period, enabling the second scanning line, and starting the third transistor of the first level pixels (S406); in a forth enabling period, stopping the enabling of the second scanning line; and in a third enabling period and a forth enabling period, utilizing the shared capacitor of the third transistor to reduce the voltage of the secondary pixel electrode of the first level pixels (S408).
