Abstract
A power circuit of a display panel and a display panel. The power circuit comprises a sensing circuit and a voltage output circuit. The sensing circuit is configured to provide a sensing signal indicative of a type of an image to be displayed by the display panel. The voltage output circuit is electrically connected to common electrodes of the display panel and configured to receive the sensing signal and change potentials of some of the common electrodes in response to a change in the sensing signal.
