Drive waveform for high resolution and high Xe content AC plasma display panels

Abstract

This paper presents a waveform for driving a high-resolution AC plasma display panel (PDP) which uses a gas mixture of high Xe content. This waveform drives the PDP with six selective-write (SW) and six selective-erase (SE) sub-fields. The SW sub-fields are addressed using wall charges formed by a modified twin reset (TR) waveform [J.W. Seo, S.H. Kim, S.Y. Soh, J.Y. Kim, J. H. Ryu, B.K. Kang, Twin voltage-ramp reset for high speed addressing of three-electrode AC plasma display panel, Displays 25(2004)49–56, and the SE sub-fields are addressed using wall charges formed by the preceding sustain discharges. A pre-reset pulse is adopted before the beginning of first SW sub-field to prevent the deteriorating effects of remnant wall charges of OFF cell on the addressing of SW sub-fields. When a 10% Xe 42″ XGA (1024×768) AC PDP was driven using the proposed waveform, the required widths of address pulse for the SW and SE sub-fields were 1.2 and 0.9 μs, respectively, and it was possible to display this PDP with the single-scan method. The measured black luminescence, peak luminescence, and contrast ratio were 0.29, 998 cd/m 2, and 3440:1, respectively. The measured sustain margins were sufficient for driving the panel with the single-scan method.
