초록

A new reset waveform with negative ramp pulse is proposed. Conventional reset waveform applied to the commercial PDP uses a positive ramp pulse. The reset waveforms, especially focused on ramp area, were examined with 2 dimensional fluid code. The proposed negative reset waveform showed much lower ignition voltage ($\sim$70V) as compared with the conventional reset waveform. When the negative ramp pulse was applied, all of the positive-charged ions are collected on the scan electrode. It is found that the ignition voltage of reset discharge due to the negative ramp pulse became lower than that of positive ramp discharge.
