The Three-Dimensional Analysis for the Discharge of Plasma Display Panel by Optical Emission Measurement

초록

We measured 3-dimensional images of the light emitted from plasma display panel(PDP) by using newly proposed scanned point detecting method (SPDM). The SPDM has the point detector with pinhole. The light emitted from PDP cell at the in-focus position can pass through the pinhole and be collected by detector. But the light emitted from PDP cel at the out-of-foucs positions is focused on the front of or the behind of the pinhole. That is, it is intercepted by the pinhole. We could analyze the characteristic of 3-dimensional discharge in PDP cell from the measured 3-dimensional light emission distribution by SPDM.
