Study on the Address Discharge Characteristics for the Analysis of the Unstable Discharge in AC PDP

AC PDP의 오방전 원인 분석을 위한 어드fp스 방전 특성에 관한 연구

Unstable sustain discharges can occur at the bottom cells of the panel at high temperature. To solve this phenomenon, the wall charge variation during an address period was investigated. A test panel of 7.5 inch XGA level was used and one green cell was measured. In order to realize operating condition equal to that of the bottom cells of 50 inch panel, the addressing stress pulses are applied. It seems that the resultant wall charge loss during address period increased with increase of temperature as well as the addressing stress pulse voltage. Therefore it results in unstable discharge during sustain period.
