Abstract

Color phosphors have been deposited on indium-tin glasses by utilizing an electrophoretic process for the application to prototype 4-inch full color FED devices. The deposition suspension is prepared with color phosphors of l-3um size, isopropanol, charger and binder. Various parameters, such as deposition time and applied voltages, are systematically performed to this end. As a result, each phosphor exhibited uniform thickness of about 6–10um over the whole plate. Electrical properties of the deposited phosphors are investigated and compared both in the vacuum chamber and in fully-sealed 4” FED conditions. In addition, they are extensively characterized by the SEM and 3-dimentional analysis. Experimental results confirm that the phosphor quality in real FED devices is significantly affected by deposition conditions.
