Abstract
A method for cleansing the phosphor screen of a display device comprising the removal of oxygen or sulfur from the surface of the phosphor, and/or its associated binder material, to a depth that prevents oxygen diffusion from the phosphor and/or binder, thereby creating an oxygen deficient surface on the phosphors.
