Patent ID: 8553025

Claim:
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.
