Abstract
A phosphor screen prepared by the electrophoretic deposition technique, as one of the promising screen processes, was analyzed for plasma display panel (PDP) application with high resolution. The electrophoretic process was systematically described in terms of the process variables based on quantitative analysis, and the optical characteristics of the screen were investigated under vacuum ultraviolet (VUV) excitation. Photoluminescent (PL) intensities of phosphor screens were dependent upon the sustaining voltage, the screen weight, and the contents of the binder with which the phosphors were charged for electrophoretic attraction. The relative PL intensity exhibited a maximum value at the screen weight of under VUV excitation. Also, the analytical equation for expressing the optical performance of phosphor screen has been derived as a function of material properties as well as screen geometry. It could be used to optimize the design parameters of the phosphor screen for PDP application. The theoretical approach from the phosphor screen model is compared with the experimental data. © 2000 The Electrochemical Society. All rights reserved.
