摘要： Provided are a method and apparatus for driving a PDP for widening a driving margin and improving contrast. The method for driving a PDP includes a first step of forming wall charges in cells with a set-up discharge using a set-up signal in a first sub-field and erasing the wall charges with a set-down discharge using a first set-down signal to initialize the cells, and a second step of erasing the wall charges with a set-down discharge generated using a second set-down signal different from the first set-down signal in a second sub-field, to initialize the cells. The method and apparatus for driving a PDP uniformly initialize sub-fields to widen the driving margin of PDP and remove a set-up discharge in at least one sub-field to improve the contrast of PDP.

摘要： A plasma display panel that minimizes the power consumption required for driving the PDP is disclosed. A reset pulse of a ramp-down waveform supplied in a reset period goes down to a voltage level higher than a negative scan reference voltage, and is kept for a specified period. Also, a sustain pulse voltage level of a selective erase type sub-field is provided with a voltage level relatively higher than the sustain pulse provided from the selective write type sub-field, or a reset pulse of a ramp-up waveform that goes from a maximum voltage level of the ramp-up waveform down to a ground voltage level or more is supplied to a scan electrode as well as a selective erase scan pulse descends from a predetermined selective erase scan voltage level to the ground level or more. Therefore, the data driving voltage is minimized, and the display state is stabilized.

摘要： A plasma display panel drive art capable of restraining a contour noise in a picture displayed on a PDP and reducing a maximum power consumption. The drive art allows one frame to be consisted of a plurality of sub fields each having a different weighting value for brightness so as to display a video signal of gray scale. The plurality of the sub fields are differently arranged along with a distribution of logical values in the video data for one frame, thereby dividing the one frame into a display interval and a non-display interval. Also, the plurality of the sub fields are equal to sub fields without a sub field having a least weighting value for the brightness.
