A fine grain low-noise luminescent screen suitable for use in high-resolution image display devices such as cathode-ray tubes, photodisplay tubes, flying spot scanners, etc., is formed on an internal surface of a transparent image display panel by settling agglomerating particles from a carrier solution to form a coating having crevices and spaces between adjacent particle agglomerates and then combining a decanting and rotating process whereby rotational movement of the panel causes the solution to wash the entire surface of the coating throughout the decanting process to deposit finer individual particles in these crevices and spaces whereby the undesirable wave patterns normally obtained during decanting are eliminated and a coating of much improved surface smoothness and uniformity of thickness and density is obtained.
