A high-speed driving technology is currently one of the most observed technologies in the driving AC-PDP. This is a required technology that allows a high image quality. In this paper, we will propose the new driving waveform which has varied V scan voltage in the same sub-field for the high-speed driving. Therefore, we were obtained 39.5V as the minimum V data voltage at the scan pulse width of 0.8μs, when the newly proposed driving waveform was applied to a 4-in. test panel. This result was that the minimum V data voltage decreased by 14.5V from the conventional driving waveform.
