Abstract: An apparatus and method for driving a plasma display panel is disclosed. The apparatus includes a level shifting unit for gradually changing a bias level of the scan bias voltage, and a scan driving unit for sequentially applying the scan bias voltage having the changed bias level to the scan electrodes.

Abstract: An apparatus and a method for driving a plasma display panel are disclosed. The driving apparatus includes a voltage source, a capacitor charged with a voltage supplied from the voltage source, or discharging the charged voltage, a first switching unit for performing a switching operation to apply the voltage from the voltage source to the capacitor and a panel, or to apply the charged voltage from the capacitor to the panel, and a second switching unit for performing a switching operation reverse to the switching operation of the first switching unit, to discharge a voltage from the panel and to discharge the charged voltage from the capacitor, or to apply the voltage from the voltage source to the capacitor and to discharge the voltage from the panel.

Abstract: The present invention relates to a plasma display apparatus and a driving method thereof. The present invention can cut off current flowing into the sustain drivers 40, 140, and 240 when the set-up signal R_up or set-down sigal R_dn is applied, even without any other switching elements by using a switching element (path-blocking switch, Sblock) with smaller capacity or by connecting the set-up switch SET_UP and the high switches 31a, 131a and 231a of the scan ICs 31, 131, and 231.

Abstract: There is provided a plasma display apparatus. The plasma display apparatus includes a scan-up switch and a scan-down switch whose one ends are connected to the panel so as to apply a scan signal to a panel; and a scan switch that is connected to a node that is positioned on a path of a resonance current flowing to the panel and the scan-up switch therebetween. Therefore, it is possible to reduce a manufacturing cost of a driving circuit for driving a panel.
