Patent ID: 7773050

Claim:
A plasma display device including a plasma display panel, the plasma display panel comprising: a plurality of first electrodes; a plurality of second electrodes disposed in approximately parallel with the plurality of first electrodes, the second electrodes forming display cells with the first electrodes adjacent to the second electrodes and discharge being executed between the first electrodes and the second electrodes forming the display cells; and a plurality of third electrodes formed in a crossing direction with respect to the first electrodes and the second electrodes, wherein during a period in which light emission of the plasma display panel is sustained, a potential of the first electrodes is maintained at a first constant potential, and a first positive voltage for the first electrodes and a second negative voltage for the first electrodes are alternately applied to the second electrodes, and a first driving circuit board for applying a voltage to the second electrodes comprises: a first switch element clamped at a high level for carrying a gas-discharge current with light emission; a second switch element clamped at a low level for carrying a gas-discharge current with light emission; a third switch element for charging and discharging capacitance of the plasma display panel via a coil; and the first, the second, and the third switch elements being IGBTs.
