Just what role do these sulphides play in this new RCA Color TV Tube which is so markedly superior to older tubes as to constitute a major breakthrough in tube design. The viewing screen of the color tube consists of tiny dots of special sulphide 'phosphors,' arranged in a series of tri angular groups, such as illustrated above. RCA Engineers discovered that use of sulphide phosphors resulted in the viewer seeing pictures of much greater brightness, more definitive sharpness and more natural colors. True, no 'tonnage' of sulphur is involved in this achieve ment and never will be but it does serve to highlight again the important role that Sulphur and its derivatives play in the 'creation of headline products!' Many are in common use in all walks of life. Many more are bound to come from research based on this versatile natural substance.
