摘要： This disclosure relates to a method for driving an AC type plasma display panel. According to this disclosure, an elapse time period between an end time point of ramp-down and a time when a first scan pulse is applied is maintained to be uniform even when a ramp-down slope is different in such a manner that a comparator of a scan electrode driving circuit compares an output voltage with a reference voltage and a logic control circuit outputs a control signal to a logic control circuit when the output voltage is equal to the reference voltage. Accordingly, the method for driving the AC type plasma display panel is capable of improving an address characteristic and a driving margin.

摘要： The number of components forming a scan electrode driver circuit is suppressed. For this purpose, a scan pulse generation circuit includes a first electric power supply for generating a positive voltage to be superimposed on the reference electric potential of the scan pulse generation circuit, high-voltage-side transistors for outputting the high-side voltage of the first electric power supply to scan electrodes, and low-voltage-side transistors for outputting the low-side voltage of the first electric power supply to the scan electrodes. A down-waveform generation circuit includes a second electric power supply for generating a positive voltage to be superimposed on the reference electric potential, and a Miller integration circuit that has one terminal connected to the high-voltage side of the second electric power supply and the other terminal connected to the ground electric potential. The down-waveform generation circuit generates a down-ramp waveform voltage falling to a negative voltage.

摘要： Protective layer (26) of front plate (20) of a plasma display panel has base protective layer (26a) and particle layer (26b). Base protective layer (26a) is formed of a thin film of metal oxide containing at least one of magnesium oxide, strontium oxide, calcium oxide, and barium oxide. Particle layer (26b) is formed by sticking, to base protective layer (26a), single crystal particles (27) of magnesium oxide having an NaCl crystal structure that is surrounded by a specified two-type orientation face formed of (100) face and (111) face or a specified three-type orientation face formed of (100) face, (110) face, and (111) face. The panel driving circuit drives the panel while temporally disposing the subfields so that the luminance weight monotonically decreases from a subfield in which an all-cell initializing operation is performed to the subfield immediately before the subfield in which its next all-cell initializing operation is performed.

摘要： Sustain discharge is stably caused while power consumption is reduced, and image display quality is improved. A plasma display device has a plasma display panel, an electric power recovering circuit for raising or falling a sustain pulse by resonating an inductor and the inter-electrode capacity of a display electrode pair, and a sustain pulse generating circuit for alternately applying, to the display electrode pair, as many sustain pulses as the number corresponding to the luminance weight in the sustain period of a plurality of subfields that are disposed in one field and have initializing, address, and sustain periods. The sustain pulse generating circuit generates at least two kinds of sustain pulses including a first sustain pulse serving as a reference and a second sustain pulse that rises more gently than the first sustain pulse, and generates the first sustain pulse immediately after the second sustain pulse.
