Patent ID: 8040296

Claim:
A plasma display device comprising: a plasma display panel having a plurality of first electrodes, a plurality of second electrodes, and a plurality of third electrodes crossing the first and second electrodes; a power supply comprising a first power source for supplying a first voltage and a second power source for supplying a second voltage higher than the first voltage; a driving circuit for driving the first electrodes; and a controller for generating a first signal to control a driving operation of the driving circuit, wherein the driving circuit comprises: a first switch for supplying a third voltage to the first electrodes, the third voltage decreasing over a period of time; a switching controller for controlling the first switch in accordance with the first signal and a second signal; and a feedback signal generator for comparing a fourth voltage proportional to the third voltage with a fifth voltage corresponding to the second voltage, adjusting a level of the second signal according to a result of comparing the fourth voltage with the fifth voltage, and supplying the second signal to the switching controller.
