A panel driving apparatus including an address power controller for blocking an address power source of at least two capacitors and coupling the panel capacitors during a period between a scan line signal and a next scan line signal, so that the panel capacitors share electric charges, and an address driver for generating display data in response to an address signal by performing a switching operation. Electric charges that are charged in a previous address electrode line and could be discarded to a ground terminal at a next address electrode line are shared between the panel capacitors, thus reducing power consumption and improving power efficiency during an addressing operation.
