Patent ID: 7911413

Claim:
A method for driving a plasma display panel based on a frame having a plurality of sub-fields, the method comprising: applying a scan electrode waveform to a scan electrode during a reset period of at least one sub-field, the scan electrode waveform including a first ramp-up section wherein a first voltage level increases, and a ramp-down section wherein a second voltage level decreases; and applying a sustain electrode waveform to a sustain electrode during the reset period of the at least one sub-field, the sustain electrode waveform including a second ramp-up section wherein a third voltage level increases during the first ramp-up section of the scan electrode waveform, and a first flat section wherein a fourth voltage level is maintained at a constant level during the ramp-down section of the scan electrode waveform, wherein the first voltage level of the scan electrode waveform and the third voltage level of the sustain voltage waveform increase at a starting point of the reset period, at a same time.
