Modified Driving Waveform for Stable High-Speed Address Discharge in AC PDP under High Xe Gas Mixture

Abstract

For the fast and stable address under the high Xe gas condition of plasma display panels (PDPs), the weak and strong discharge characteristics in both surface-gap and plate-gap discharges were examined for two different Xe gas contents (7 and 20%). It is observed that it is very difficult to produce the strong plate-gap discharge required for the address discharge as the Xe gas content increases from 7 to 20%, thus requiring an additional voltage increase for the strong plate-gap discharge. Based on these experimental observations, the modified driving waveform, featuring being able to produce an intensified address discharge in the plate-gap discharge without a misfiring discharge in the surface-gap discharge, is proposed for the successful high speed address of the high Xe PDP.
