摘要： In a reset period, through applying a rectangular pulse (Pya) of positive polarity to an electrode (Y) and applying a CR pulse (Pxa) of negative polarity to an electrode X, a full lighting pulse is applied between the electrodes (X and Y). The application of the voltage is stopped before a CR pulse (Pxc) reaches a final potential, to generate the pulse (Pxa). A full erase pulse (Pxb) made of a CR pulse having a polarity reverse to that of the pulse (Pxa) is applied to the electrode (X). An erase operation reverses the polarity of wall charges accumulated by a full lighting to effectively perform a potential control operation. The potential control pulse (Pxc) is applied to the electrode (X) to generate a discharge, and the state of the wall charges in a discharge cell is controlled by the discharge to generate an optimal amount of wall charges for a subsequent addressing discharge. The final voltage of the pulse (Pxc) is set equal to a voltage (−Vxg) of an address pulse (Pa). Thus, it is possible to generate a plurality of pulses and stabilize an operation of a PDP with a simple constitution.

摘要： A synthetic round pulse generation circuit can output constant currents (i1, i2). By charging a capacitance element (CP) with the constant currents (i1, i2), a ramp pulse (10a) having a rate of voltage change of i1/CP and a ramp pulse (10b) having a rate of voltage change of i2/CP are applied to the capacitance element (CP). A synthetic round pulse (11) consists of the ramp pulse (10a) and the ramp pulse (10b). In the synthetic round pulse (11), the lengths of application time periods (T10a, T10b) are set so that a discharge is started with the ramp pulse (10a). Further, the rate of voltage change (i1/CP) of the ramp pulse (10a) is set to a small value so that the intensity of the discharge at a discharge starting time (t11f) in the application time period (T10a) may be sufficiently weak. When a PDP is driven with the synthetic round pulse, it is thereby possible to reduce an application time of the round waveform.

摘要： Charge accumulated in a capacitor is used to provide a processing current flow between a target and an electrode. When a diode is turned on, a first dc power supply is used to provide the processing current flow between the target and the electrode. In this state, after a lapse of a predetermined time, the current supply using the first dc power supply is stopped, and an induced electromotive voltage, induced by two floating reactors, is used to rapidly drop the processing current flowing between the target and the electrode, while charging the capacitor.
