Title: Plasma display apparatus

Abstract: A PDP apparatus comprises, in a circuit part, a ramp output device which outputs a ramp wave to electrodes of a PDP. The ramp output device has a ramp generator which generates and outputs a first ramp wave of which inclination is variable, 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 the input of the ramp generator. The ramp generator outputs the second ramp wave as a ramp wave (output voltage). Techniques to realize output of stabilized ramp wave in a PDP apparatus so as to stabilize PDP display operations are provided.
