Abstract:
1. A plasma display apparatus comprising: a plasma display panel in which a capacitive load is formed by a plurality of electrodes; and a circuit part which applies a drive voltage to the electrodes, wherein the circuit part has a ramp output device which outputs a ramp wave of an applied voltage which gradually increases or gradually decreases along with time as the voltage applied to the electrodes; the ramp output device comprises: a ramp generator which generates and outputs a first ramp wave and electrically changes the inclination of the first ramp wave which is an output of the circuit; an impedance conversion circuit which receives the first ramp wave as input and outputs a second ramp wave produced by impedance conversion; and a feedback circuit which receives the second ramp wave as input and feeds it back to an input of the ramp wave generating circuit, and the second ramp wave is outputted as the ramp wave applied to the electrodes.
