インデックス型カラーテレビジョン受像機。, a black guard band is formed between at least predetermined phosphors of the three primary color phosphors of red, green, and blue repeatedly arranged in a striped manner on the inner surface of the face plate of the cathode ray tube; When an electron beam emitted by a single electron gun is swept over a surface consisting of a phosphor and index elements repeatedly arranged in a stripe pattern in regular relation to each other, an index signal generated from the index element is used to generate the index element. In a television receiver in which an electron beam impacts a predetermined phosphor, the spot diameter of the electron beam is made larger than the width of one cacodoban, and when reproducing intermediate colors, the triplet of the three primary color phosphors is A beam index type color television receiver that performs lossmask scanning by delaying horizontal scanning in the vicinity of a phosphor necessary for generating intermediate colors using a signal with a frequency corresponding to the repetition frequency.
