PLASMA DISPLAY AND DRIVING METHOD THEREOF

A plasma display apparatus and a driving method thereof are provided to reduce power consumption by varying voltages of scan electrodes using resonance between an inductor and a panel capacitor during an address period. A plasma display apparatus includes scan electrodes, first, second, third, and fourth switching elements, an inductor(L), and a first capacitor(C1). The scan electrodes apply scan pulses having a first voltage and a second voltage lower than the first voltage. A first end of the first switching element is connected to a first voltage source for supplying the first voltage and a second end thereof is connected to the scan electrodes. A first end of the second switching element is connected to a second voltage source for supplying the second voltage and a second end thereof is connected to the scan electrodes. A first end of the inductor is connected to the scan electrodes. The first capacitor connected to a second end of the inductor charges a third voltage between first and second voltages. A first end of the third switching element is connected to the second end of the inductor and a second end thereof is connected to the first capacitor. A first end of the fourth switching element is connected to the second end of the inductor and a second end thereof is connected to the first capacitor. By turning on the first and third switching elements during a first period in the supplement of the first voltage to the scan electrodes, magnetic energy is stored in the inductor. By turning on the second and fourth switching elements during a second period in the supplement of the first voltage to the scan electrodes, magnetic energy is stored in the inductor.
