Patent ID: 7379033

Claim:
A plasma display device, which includes a plurality of first electrodes and a plurality of second electrodes, and a panel capacitor being formed by a first electrode and a second electrode, the plasma display device comprising: a first driver including a first inductor having a first end coupled to the first electrode and a second inductor having a first end coupled to the first electrode, and to apply a first voltage and a second voltage to the first electrode in turn; and a controller to calculate a load ratio from video signals and to control an operation of the first driver, wherein the first driver applies the first voltage to the first electrode after raising the voltage of the first electrode through the first inductor, supplies energy to the second inductor during a first time period while maintaining the first electrode at the first voltage, and applies the second voltage to the first electrode after reducing the voltage of the first electrode through the second inductor, and the first time period has a first duration if the load ratio is less than a predetermined value and a second duration if the load ratio is greater than the predetermined value, the first duration being shorter than the second duration.
