Abstract
A driving circuit for driving a display panel including a plurality of cells arranged in rows. The driving circuit comprises a gate electrode driving circuit to provide a gate voltage to a row of cells, a common electrode driving circuit to provide a common voltage to the row of cells, and an external capacitor coupled to the gate electrode driving circuit and the common electrode driving circuit to provide an additional gate voltage to the row of cells. The external capacitor is charged by a potential difference between the common voltage and the gate voltage.
