摘要： A display screen comprising a phosphor composition which includes a phosphor and a phosphor coating with a group of metal-oxygen compounds, the group of metal-oxygen compounds containing an yttrium-oxygen compound, is characterized by a surprising improvement in picture brightness, color purity and adhesion of the phosphor composition to the glass of the display screen. The phosphor layer exhibits a high packing density of the phosphor material. The phosphor layer further exhibits a good homogeneity and is free from “pinholes”. In addition, the structured phosphor layer shows a high definition.

摘要： A display screen, in particular a color display screen for a cathode ray tube, comprises a phosphor layer which includes a phosphor composition of a phosphor with a coating comprising a water-soluble organic binder, which is selected from the group formed by the polyurethanes, polyacrylamides, polyamide resins, etherified melamine compounds and melamine-formaldehyde compounds, and etherified urea-formaldehyde resins, and comprising oxygen compounds of one or more elements selected from the group formed by the alkaline earth elements and zinc. Important advantages obtained are a substantially improved sieving behavior of the phosphor powder, an increased adhesion of pigment particles to the phosphor grains, an improved suspension stability as well as an improved adhesion of the phosphor to the display screen glass.
