Plasma display apparatus with power recovery circuit

1. A plasma display apparatus comprising:

a plasma display panel including a plurality of scanning electrodes extending in a first direction and a plurality of address electrodes extending in a second direction crossing the first direction;

an address driver to drive the address electrodes;

a power recovery circuit including an inductor and a capacitor;

a switch provided in the address driver to switch connection and disconnection between the address electrodes and the power recovery circuit;

an address driver output stage included in the address driver to supply one of a high-level voltage and a low-level voltage for the address electrodes; and

a control unit to control on-time of the switches based on a switching conversion ratio between the high-level voltage and the low-level voltage,

wherein the address driver includes a plurality of switches corresponding to the plurality of address electrodes;

the power recovery circuit is provided outside the address driver;

the plurality of switches are connected in parallel to the power recovery circuit; and

the control unit shortens the on-time if the switching conversion ratio between the high-level voltage and low-level voltage is small, and lengthens the on-time if the switching conversion ratio between the high-level voltage and low-level voltage is large.

2. The plasma display apparatus as claimed in claim 1 ,

wherein the power recovery corresponding to the address driver is provided.

3. The plasma display apparatus as claimed in claim 1 ,

wherein the power recovery circuit is provided for a plurality of address drivers in common.
