摘要： A PDP drive method capable of restraining the generation of contour noise and making to be high a brightness level. In the PDP drive method, discharging cells on the plasma display panel start simultaneously on a radio frequency discharge by row lines. Next, the radio frequency discharge, which is caused in each discharging cell on the row line, is erased by applying an erasing pulse corresponding to a brightness level of video to the discharging cells on a row line.

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.
