The 3- dimensional analysis for the discharge of PDP according to the pulse width of voltage applied to the address electrode during sustain period

Sustain 구간중 Address 전극에 인가되는 전압 펄스 폭에 따른 3차원 방전형상 분석

We measured 3-dimensional temporal behavior of the light emitted from AC plasma display panel(PDP) at various auxiliary voltage pulse width supplied to the address electrode in sustain period using scanned point detecting system. In the case of applying an auxiliary address voltage pulse, the light emission starts at the inner edges of the cathode so the larger discharge volume toward address electrode can be obtained compared with the normal sustain discharge. Especially, when the auxiliary voltage pulse width is the $2{\mu}s$, the maximum luminance and long emission time can be obtained.
