Abstract: A method of filming a luminescent screen is disclosed which improves the light output of CRTs that contain printed phosphor lines. The method incorporates both the application and film formulation requirements and optionally includes in-line diagnostic techniques. The novel film formulation contains a lacquer and solvents, wherein one of the solvents is a non-solvent for the lacquer. The optional diagnostic technique include surface gloss measurements to characterize and monitor the process and provide predictive capability of CRT performance with respect to light output.

Abstract: A method of manufacturing a luminescent screen assembly for a color cathode-ray tube (CRT) is disclosed. The luminescent screen assembly is formed on an interior surface of a faceplate panel of the CRT. The luminescent screen assembly includes a light-absorbing matrix having a plurality of substantially equally sized openings formed therein. The matrix is formed by applying one or more light sensitive layers on the interior surface of the faceplate panel of the CRT tube. The one or more light sensitive layers includes a photoresist material. Also, the one or more light sensitive layers includes a contrast enhancing material. The one or more light sensitive layers are selectively exposed to actinic radiation projected through openings in a shadow mask, positioned a fixed distance from the screen assembly.
