A plasma display panel (PDP) consists of more than a thousand very thin parallel electrodes on a glass plate. It is quite probable that a PDP has defects such as midway broken electrodes. Therefore, inspecting defects in PDP electrodes is essential for minimizing the manufacturing costs and improving the product quality. In this paper, a new method for inspecting electrodes in a PDP using frequency domain analysis is presented. The transfer function of a PDP was modeled in the frequency domain, which is based on the lumped transmission line models. The effects of the electrode conditions on the frequency response were then analyzed by using the described model, and experiments were conducted with specimens to confirm the presented inspection method. The experimental results are in good agreement with the analytical results. Therefore, the presented method using frequency domain analysis was confirmed to be a good method for inspecting the electrode conditions in PDPs
