Abstract
A method for forming a cathodoluminescent screen by forming cathodoluminescent films on the inner surface of screen panel for a field emission display by a screen printing, a spray, or an electrodeposition process. The field emission display cathodoluminescent particles for improving a luminescent emission efficiency, wherein the improved cathodoluminescent particles are formed by coating a uniform phosphor material on the surfaces of cathodoluminescent particles by an atomic layer deposition.
