Abstract :
The address discharge characteristics of the plasma display with a MgO single cathode layer and the one with a MgO-SrO double cathode layer were investigated. In particular, the conventional waveform with a positive-going ramp and the proposed waveform with a negative-going ramp were applied in order to demonstrate that the polarity of the scan electrode during the reset period affects the dynamic voltage margin and the address discharge time lag. It was confirmed that the total address discharge time lag of the plasma display with the MgO-SrO double cathode layer decreased by about 550 ns by applying the proposed waveform with the negative-going ramp.
