PLASMA DISPLAY DEVICE AND ITS DRIVING METHOD

摘要

PROBLEM TO BE SOLVED: To perform stable address operation even in high-speed driving and to display a high-definition image of high picture quality. SOLUTION: A maintenance pulse is applied to a maintenance electrode 19b in the ending of a maintenance period and then while negative wall electric charges are accumulated on the side of the maintenance electrode 19b in the ending of a discharge period, positive wall electric charges are accumulated on the side of a scanning electrode 19a. In a discharge stop period, an erasure pulse having a ramp waveform whose leading edge has a gradientαe [V/μs] is applied between the scanning electrode and maintenance electrode while the scanning electrode has the positive polarity, and a positive wall voltage is left on the side of the scanning electrode 19a. In an initialization period, positive initialization pulses are applied to scanning electrode groups 19a1 to 19aN. Consequently, an initialization discharge time S becomes long and the discharge probability of address discharge is improved.
