摘要： A method and device for driving a plasma display panel are provided that do not cause false lighting even if the all-cell initializing operation becomes unstable. In an initializing period of a subfield, an all-cell initializing operation of causing initializing discharge in all discharge cells or a selective initializing operation of causing initializing discharge in the discharge cell that has caused sustain discharge in the last sustain period is performed. In a field corresponding to an image signal for displaying black on the whole screen, an abnormal charge erasing period for applying rectangular waveform voltage to the scan electrode is disposed after the initializing period in the subfield where the all-cell initializing operation is firstly performed. In a field corresponding to an image signal other than the image signal for displaying black on the whole screen, an abnormal charge erasing period for applying rectangular waveform voltage to the scan electrode is disposed after the initializing period in any subfield after the subfield where the all-cell initializing operation is firstly performed.

摘要： In a circuit driving a capacitive load Cp, current passed through a transistor Q3, a diode D1 and a recovering coil L is passed through lines L1, L2, and the inductance components of the lines L1 and L2, and the drain-source capacitances of the transistors Q1 and Q2 generate LC resonance. Capacitors C1 and C2 are connected in parallel to the drain-source regions of the transistors Q1 and Q2 to increase the total drain-source capacitance and reduce the resonance frequency, so that unwanted electromagnetic wave radiation in a frequency band affecting other electronic devices is suppressed.

摘要： An AC plasma display panel includes a plurality of parallel scan electrodes and a plurality of parallel sustain electrodes. Each of sustain electrodes is extended parallel to scan electrodes. Scan and sustain electrodes are positioned alternately so that each one of scan and sustain electrodes positions adjacent to and paired with the other of scan and sustain electrodes. Also, the panel includes a plurality of parallel data electrodes. The data electrodes extend substantially perpendicular to scan and sustain electrodes. Scan and sustain electrodes are applied with a certain current so that an electromagnetic noise generated in the electrodes can be cancelled by another.
