Abstract
A new sustain driving waveform and its implementation method is proposed to improve the gray scale linearity by applying the sustain waveform for producing the strong and weak discharge in AC plasma display panel. The driving method to express the gray scale of AC PDP is the combination of the several subfield in one TV frame, and the luminance of the each subfield is decided by the number of the sustain pulses. As the same amount of the strong plasma discharge is produced when the sustain pulses are applied during a sustain period, it looks easy to express the linear gray scale ideally. However, it is difficult to express the real linear gray scale due to the production of the address and first sustain discharge irrelevant to gray scale expression in every subfleld. Therefore, a new sustain driving waveformis adopted to produce partially the weak discharge instead of the strong discharge by the modification of the sustain pulses shape during the sustain period and the gray scale expression is close to the linearity.
