Patent ID: 7460089

Claim:
A driving apparatus of a plasma display panel having a capacitive load formed by at least two electrodes, comprising: a first transistor having a first main end coupled to a first electrode of the capacitive load; a capacitor having a first end coupled to a second main end of the first transistor and a second end coupled to a first power supplying a first voltage; and a second transistor coupled between the second main end of the first transistor and a second power supplying a second voltage, wherein the capacitor receives charges from the capacitive load when the first transistor turns on; wherein a voltage at the first electrode is reduced by repeating a process of turning on and turning off the first transistor during a reset period; and wherein the first transistor and the second transistor turn on during an address period such that the second voltage is applied to the first electrode via the first transistor and the second transistor.
