Abstract:
1. An address driving circuit comprising: a driving device unit configured to drive an address electrode to an address voltage or a reference voltage in response to driving control signals during an address period; and an energy recovery circuit configured to recover a voltage charged to the address electrode in response to switching control signals such that a voltage of the address electrode transitions to the address voltage or the reference voltage through at least two intermediate voltages including a first intermediate voltage and a second intermediate voltage during the address period, wherein the energy recovery circuit comprises: a first switching element, connected to the address electrode, which receives a first switching control signal; a second switching element, connected to the address electrode and to the first switching element in parallel, which receives a second switching control signal; a first energy recovery capacitor, connected to the first switching element, which recovers the voltage charged to the address electrode; and a second energy recovery capacitor, connected to the second switching element, which recovers the voltage charged to the address electrode.
