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 cell at the out‐of‐focus 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 distributionbySPDM. From 3‐dimensional measurement, we know that as the sustain voltage increases, the intensity of detected light increases and the position of the maximum intensity moves to the outside from the electrode gap. The emitted light distributions on the ITO electrode show the stronger light intensity at the near to the electrode gap than at the outside. Also, we know that 2‐dimensional simulations under the assumption that neglects the variation of parallel direction with electrode do not agree with 3‐dimensional experiment results that consider the variation of parallel direction with electrode.
