PLASMA DISPLAY PANEL APPARATUS DRIVING METHOD AND PLASMA DISPLAY PANEL APPARATUS

摘要

During a former half (T₁₁) of an all-cell initializing period (T₁), the potential at a scan electrode (Scn) is raised from zero volts to Vp volts at a timing t₀, and thereafter, the scan electrode (Scn) is maintained at the positive potential of Vp to Vg volts until a timing t₃ when the former half (T₁₁) terminates. On the other hand, during the same former half (T₁₁), an initializing pulse (Pul.2), which includes a negative ramp waveform portion from zero volts to a potential of Vr volts, is applied to a sustain electrode (Sus). It is arranged that a time period (t₁-t₀) of the negative ramp waveform portion of the pulse (Pul.2) is longer than a time period required for the potential change of the pulse (Pul.1) from P₁ to P₂.
