Abstract:
A method of manufacturing a field emission display comprising;forming an anodic faceplate including depositing a layer of phosphor on a substrate; forming a cathodic baseplate including a plurality of emitter tips; removing oxygen contaminants from a surface of the phosphor layer to a depth of at least approximately 50 to 70 angstroms such that substantially no additional oxygen contaminants will dissociate from the layer of phosphor during subjection of the layer of phosphor to an electron energy at an intended operating level, wherein removing oxygen contaminants includes subjecting the phosphor layer to an electron energy at a voltage less than an intended operating voltage of the display; and sealingly assembling the faceplate and baseplate together subsequent the removal of the oxygen contaminants from the phosphor layer.
