Abstract: A plasma display apparatus has a waveform of a driving voltage supplied from a driver. The waveform has a sustaining period when a sustaining pulse is alternately applied to scanning electrodes and sustain electrodes for keeping discharge. Besides, the waveform has an erasing period when a ramp voltage pulse whose polarity differs from that of a sustaining pulse is applied to an electrode, which differs from an electrode where a last pulse of the sustaining pulse is applied. As a result, false discharge is prevented, and a stable image can be displayed.

Abstract: During a period in which electron beam emission to a photo-emissive screen is inhibited, a heating current is supplied to a cathode. During a period in which electron beam emission to the screen is enabled, the supply of the heating current to the cathode is interrupted and the potential at the cathode is varied with a video signal. During the beam emission enabling period, the interruption of the heating current supply allows the electron beam to be uniform along the cathode, since the heating current would cause a potential gradient or variation along the cathode. In addition, during the beam emission enabling period, since the cathode potential is varied with the video signal, the electron beam is modulated in accordance with the video signal.
