摘要： A method of driving a plasma display panel for generating picture or image with high quality while suppressing luminance to a low level in the display in black. One field for image display is composed of at least two different types of subfields first and second subfields. In the first subfield (subfield A), a reset period is provided in which after a priming pulse (Pp) having a voltage value and a pulse width has been applied between X- and Y-row electrodes for causing discharge to occur in all of pixels, then the voltage applied between both the electrodes is set to zero for erasing wall charge after the discharge of all of the pixels, while in the second subfield (subfield B), a reset period is provided in which an erasing pulse (Ep) having a voltage value and a pulse width for causing only the pixels discharged in the preceding subfield to be discharged has been applied for allowing only the pixels discharged in the preceding subfield to be discharged, the wall charge is erased by setting to zero the voltage applied between the X- and Y-row electrodes.

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： 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 wall-voltage generation period is provided once in every several tens or hundreds of frames. A wall voltage (broken line) generated in the wall-voltage generation period does no disappear irrespective of the presence or absence of discharge emission. The presence or absence of discharge emission is controlled by varying the baseline of a voltage across electrodes (solid line) depending on variations in an address voltage (Va) during a display period. The number of priming reset discharges which has been necessary at least once in each frame can be reduced.

摘要： A variable dispersion compensator includes an optical waveguide, a temperature controller. The optical waveguide has a chirped grating having a Bragg wavelength changing along the longitudinal direction of the grating. A temperature distribution T1(x) is applied to a central portion of the grating, defined as a region where a distance x from an end of the grating is a range of 20 % to 80 % of total length of the grating. Temperature distribution T2(x) and T3(x) are applied to end portions of the grating, defined as two regions extending from respective ends of the grating to the central region, respectively. At least one of T2(x) and T3(x) has a distance dependence different from that of the T1(x).
