Abstract:
1. A device for driving a plasma display panel (PDP), comprising: a transistor having a first main end coupled to a capacitive load, a second main end coupled to a power source, and a control end; a control end voltage control circuit coupled between a control signal voltage source and the control end of the transistor; wherein the control signal voltage source alternately generates a control signal of a first level and a second level, and transmits the control signal to the control end voltage control circuit, wherein the control end voltage control circuit, in response to the control signal of the first level, applies a first voltage to the control end of the transistor to turn on the transistor, and then changes the voltage to the control end of the transistor to a second voltage for turning off the transistor within a predetermined period after the control signal of the first level is applied, and wherein the predetermined period is shorter than a period in which the control signal is maintained at the first level.
