Abstract
A plasma display panel apparatus includes a pair of discharge sustaining electrodes, a panel capacitor to supply charged voltage alternately to each electrode of the pair of discharge sustaining electrodes, a switching device for discharge that is turned on when the panel capacitor is discharged, to thereby pass through discharged current of the panel capacitor, a current sensing part to sense the current passed through by the switching device for discharge, and an over-current controlling part that turns off the switching device for discharge when the current sensed in the current sensing part is at or above a predetermined reference value. With this configuration, the plasma display panel apparatus protects the switching device from over-current generated during an abnormal driving of the discharge sustaining electrode driving circuit.
