플라즈마 디스플레이 패널에서 방출되는 광의 3차원 시간 분해 측정

초록

In this paper, we measured 3-dimensional temporal behavior of the light emitted from discharge cell of plasma display panel using the scanned point detecting system. The detected light signa through the PM tube is sent on the oscilloscope and oscilloscope is connected to PC with GPIB. The whole system is controlled by a PC. From the temporal behavior results, we could analyze the discharge behavior of panel with Ne-Xe (4%) mixing gas and 400 torr pressure. The top view of panel shows that discharge moves from inner edge of cathode to outer cathode electrode forming arc type. The side view of panel shows that the light is detected up to 150 um height of barrier rib. After trigger pulse is applied. Peal intensity is detected at 730 ns and peak intensity position is the center of the ITO electrods.
