PLASMA DISPLAY PANEL DEVICE AND DRIVE METHOD THEREOF

摘要

There is provided a PDP device capable of suppressing generation of erroneous discharge during the entire cell initialization period and generation of flickering in a low gradation if the voltage applied to the data electrode is increased for fine resolution when characteristic irregularities are generated in the panel plane or a discharge start voltage lowered area is generated by a long period of drive. A method for driving the PDP device is also disclosed. A pulse Pul.3 to a data electrode Dat is performed at timing t0, i.e., with temporal relationship preceding to timing t1 for increasing the potential of the scan electrode Scn to Vq(V). Accordingly, in this drive method, at timing t0 when voltage Vx(V) is applied to the data electrode Dat to generate discharge Dis.3, no potential difference exists between the scan electrode Scn and the sustain electrode Sus. The discharge Dis.3 generated between the data electrode Dat and the sustain electrode Sus by the lowering of the discharge start voltage serves as a trigger and spreads to the side of the scan electrode Scn without causing erroneous discharge.
