摘要： A method for driving a display panel to produce an efficient sustain discharge is provided. In one embodiment, the display panel includes a plurality of scanning electrodes that are driven by a sustain discharge signal. A corresponding plurality of common electrode groups is driven individually by different sustain discharge signals. Sustain discharge is performed by alternately applying high level sustain pulses to each the plurality of scanning electrodes and each the plurality of common electrode groups. Sustain pulses with a high level are applied sequentially to each the plurality of common electrode groups in time intervals between the sustain pulses with the high level applied to the plurality of scanning electrodes. Therefore, it is possible to maintain a duty rate of a sustain discharge signal near 50% while reducing a peak value of currents generated upon sustain discharge driving, thereby achieving stable sustain discharge.

摘要： In a plasma display panel driving method, a final voltage of a falling ramp voltage is reduced to a voltage for firing a discharge at all the discharge cells in a reset period. A difference between a voltage at an address electrode of a discharge cell to be selected and a voltage applied to a scan electrode is established to be greater than a maximum discharge firing voltage in an address period. A voltage greater than a sustain voltage is applied to the scan electrode so as to convert positive wall charges which can be formed on the scan electrode of a discharge cell which is not selected in the address period into negative wall charges.

摘要： A method for driving a plasma display panel having front and rear substrates opposed to and facing each other, X and Y electrode lines between the front and rear substrates and parallel to each other and address electrode lines orthogonal to the X and Y electrode lines, to define corresponding pixels at intersections. In the driving method, a scan pulse is applied to the respective Y electrode lines with a time difference and the corresponding display data signals are simultaneously applied to the respective address electrode lines to form wall charges at pixels where a display discharge is to occur. Pulses for a display discharge are alternately applied to the X and Y electrode lines to cause a display discharge at the pixels where the wall charges have been formed. Also, the pulses for display discharges simultaneously applied to the X electrode lines start after the pulses for display discharges simultaneously applied to the Y electrode lines terminate, and the scan pulses and the corresponding display data signals are applied after the pulses for display discharges simultaneously applied to the X electrode lines terminate and before the pulses for display discharges simultaneously applied to the Y electrode lines start. The power levels of pulses for display discharges simultaneously applied to the Y electrode lines are greater than the power levels of pulses for display discharges simultaneously applied to the X electrode lines.

摘要： A resetting method includes a line discharge step, an erasure step, and an iteration step. The line discharge step is performed during a part of a first pulse width period. During the first pulse width period since a second subfield corresponding to a first XY-electrode line pair starts after a first subfield corresponding to the first XY-electrode line pair ends, a negative voltage of a first level is applied to all X-electrode lines, and simultaneously, a positive voltage of the first level is applied to all Y-electrode lines. In the line discharge step, a negative voltage of a second level higher than the first level is applied to an X-electrode line of the first XY-electrode line pair, and simultaneously, a positive voltage of a third level higher than the first level is applied to a Y-electrode line of the first XY-electrode line pair, thereby provoking discharges in all discharge cells corresponding to the first XY-electrode line pair. In the erasure step, wall charges are erased from all of the discharge cells corresponding to the first XY-electrode line pair. In the iteration step, the line discharge step and the erasure step are repeatedly performed on all XY-electrode line pairs other than the first XY-electrode line pair.

摘要： In an address-while-display (AWD) driving method in which addressing and sustaining are simultaneously performed, a plasma display panel (PDP) is driven with an automatic power control function for reducing power consumption when there are lots of ON pixels over the entire PDP, that is, the brightness of the screen of the PDP is higher than a predetermined level. In the PDP driving method, in order to suppress power consumption for maintaining a bright state of the screen, discharge sustain pulses at respective sub-fields for implementing gray scale display of each frame are invalidated using erase pulses in a constant ratio for each sub-field, while all the video signals applied in the form of the AWD driving waveforms are continuously applied to the respective frame periods in which all the video signals are displayed without interruption, that is, irrespective of whether discharge is performed. Thus, while attaining an improvement in the luminance by applying many discharge sustain pulses based on the AWD driving method, the power consumption at high luminance is automatically reduced.
