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： Before applying a pulse (Vp) of the first voltage for uniforming charges between each of the first electrodes X and each of the second electrode Y1 to Yn which are adjacent to each other, a pulse (Vpp) of the fifth voltage which has a reverse polarity to that of the pulse of the first voltage and is lower than the pulse of the first voltage and higher than the pulse of the fourth voltage for sustaining a discharge is applied between the first and second electrodes. Thus, in a method for driving a plasma display in which cells are provided at intersections of a plurality of electrodes, a full write discharge is surely caused even if residual wall charges are left, and luminous efficiency is increased.

摘要： A control circuit performs ON/OFF control for a switching element so that LED current flowing in an LED unit is within a rated current range. In the case where the LED unit is lit, a voltage applied between both ends of series connection of a reactor and the LED unit becomes a first bus voltage, when the switching element is ON, and becomes a voltage lower than the first bus voltage, that is determined based on the first bus voltage and a second bus voltage, when a switching element is OFF.

摘要： A switching element operates to be turned on or off at a frequency in the order of megahertz. A reactor supplies a resonance current generated by resonance of the reactor with a floating capacitance between electrodes to between the electrodes. The resonance current does not flow in a direct-current power supply. By turning a capacitor and a floating inductance into a serial resonant state, the reactor ideally supplies the resonance current to between the electrodes without influence of the floating inductance. A high-frequency voltage asymmetric in positive and negative polarities is applied to between the electrodes and a current pulse can be made into a short pulse. Therefore, finish machining with high surface roughness can be performed.
