A new driving waveform for stable address discharge in an alternating current plasma display panels

Abstract

Although the selective ramp reset waveform having one reset period during one television (TV)-field has a higher contrast ratio than the conventional ramp reset waveform with eight reset periods, the address discharge using the selective ramp reset waveform in a stripe barrier rib is severely influenced by the crosstalk. This problem of crosstalk among the cells constitutes the main obstacle to the development of high-resolution alternating current plasma display panels (AC-PDPs). In this paper, a new driving waveform is proposed, which renders the address discharge stable by decreasing the crosstalk, in addition to reducing the background luminance. In order to compare the address discharge stability of the proposed waveform with that of the conventional ramp reset waveform, we investigated the address discharge time lag through the photo-waveform measurement of address discharge for three waveforms and measured the dark room contrast ratio. As shown in the results, without decreasing the contrast ratio or the change of the panel structure, the address discharge time lag was considerably improved by the proposed waveform
