Abstract
A display panel is provided and includes a display unit and a control unit. The display unit is coupled to a data line and a first scan line. In the display unit, a liquid crystal capacitor is coupled between a pixel electrode and a first common line, and a storage capacitor is coupled between the pixel electrode and a second common line. The control unit receives first and second common voltages and is controlled by first and second control voltage signals and first and second scan signals which are respectively on the first scan line and a second scan line and driven sequentially. The control unit changes the voltage level of the second common line by a two-step manner according to the first and second common voltages. Through feed-through effect of the storage capacitor, the voltage level of the pixel electrode is changed to a desired level.
