Abstract
In this paper, we present a new reset waveform for a large-sustain-gap structure in ac PDPs. In the driving of the large-sustain-gap structure with a conventional ramp reset waveform, we cannot avoid the condition of an address being a cathode, which causes lots of trouble in stabilizing a reset discharge. To solve these problems, we use the square pulse instead of the conventional rising ramp pulse. Before making a strong discharge between the address (cathode) and scan (anode) electrodes, we make a priming discharge between the address (anode) and the scan (cathode) electrodes to stabilize the strong discharge in which the address electrodes are the cathode. With this scheme, we obtained 60V minimum address voltage and 145V maximum address voltage in 250μm and 350μm gap structures.
