ABSTRACT:
A method of manufacturing a phosphor screen (22) on an interior surface (23) of a faceplate panel (12) is characterized by the steps of: forming a light-absorbing matrix (24) on an interior surface (23) of the faceplate panel (12); applying an aqueous surfactant solution thereto to solubilize oily contaminants and emulsify undissolved oily contaminants of the matrix (24); and serially applying three light-emitting phosphors (G, B, R) to the interior surface (23) of the faceplate panel (12) to form the phosphor screen (22).
