Abstract: A driving circuit for a display panel includes a common voltage generating circuit. The common voltage generating circuit is coupled to multiple common electrodes of the display panel and configured to provide multiple common voltages respectively to the common electrodes. During a frame period, the common voltage generating circuit respectively changes a voltage level of the common voltages at different time.
