Patent ID: 7436374

Claim:
A plasma display panel comprising: a power supply adapted to receive an Alternating Current (AC) power input and to supply power to the plasma display panel; a driving circuit adapted to drive the plasma display panel with voltages and currents supplied from said power supply; a logic unit adapted to output a control signal to control said driving circuit; and a plasma panel adapted to display video data from said logic unit, said plasma panel including a plurality of address electrodes and a plurality of first electrodes and a plurality of second electrodes arranged to intersect said address electrodes; wherein said power supply includes a power off detector adapted to detect an internal voltage of said power supply and to determine if the AC power input to said power supply has been turned off on the basis of the detected internal voltage; wherein said logic unit is adapted to output a control signal to turn off the plasma display panel in response to an output signal from said power off detector indicating that the AC power input has been turned off; and wherein said power off detector includes a discharge voltage detector adapted to detect a voltage for a sustain discharge of the plasma display panel from among the voltages supplied from said power supply and to output a signal corresponding to the detected voltage.
