ABSTRACT:
A method of manufacturing phosphor screens is disclosed. The method uses "sol-gel" for disposing a thin film of phosphor on a transparent substrate. The thin film of phosphor is applied in continuous form or in the form of an accurate dot pattern. The rastering of said dot pattern is performed either by screen printing before annealing the sol-gel, or by selective laser curing of a continuous thin film and washing off the non-cured portions. The phosphor screens are useful as monochrome or as full-color faceplates of field emission displays or cathode ray tubes.
