Abstract

PURPOSE: To facilitate an easy chroma scanning action as well as to simplify the circuit constitution by securing the same frequency for the chroma scanning signal at reproduction of the intermediate color as the chroma scanning signal at reproduction of the primary color.
CONSTITUTION: The three primary color fluorescent substances R (red), G (green) and B (blue) are arrayed repetitively in stripes on the inner surface of face plate 2 of CRT1 as if they held guard band 3 of black color between, and then index element 4 is added with a regular relation with R, G and B respectively. The electron beam is swept to plate 2, and the impact of the electron beam is given to R, G and B via the index signal produced from element 4. In such TV picture receiver, the spot diameter of the electron beam is set larger than the width of guard band 3. And the same frequency is secured for the chroma scanning signal to be applied to auxiliary deflecting coil 11 at reproduction of the intermediate color as the chroma scanning signal at reproduction of the primary color. And the horizontal deflecting scanning is retarded for the chroma scanning signal at the part of band 3.
