PURPOSE: A device and a method for driving an AC type plasma display panel are provided to reduce power consumption by improving a luminance and realizing a stable reset section and address period. CONSTITUTION: The fifth switching NMOS transistor is turned on, and an electric charge is charged at the first capacitor(651) with 165V. Next, the first switching NMOS transistor is turned on, and an auxiliary sustain voltage(Vp) of 15V is charged at the capacitor according to a characteristic of the capacitor, and the final voltage of the capacitor reaches 180V. At this time, the 180V is the final sustain voltage level. Because the auxiliary sustain voltage(Vp) is 15V and the sustain voltage is 165V, the final sustain voltage level becomes 225V in the case that the first to the fourth switching NMOS transistors are turned on. |
