ジヨン受像機。 The three primary color phosphors of red, green, and blue are arranged repeatedly in stripes on the inner surface of the panel of the cathode ray tube body, and the index phosphors are arranged repeatedly in stripes in a regular relationship with these three primary color phosphors. When the phosphor screen is swept with an electron beam emitted from a single electron gun, an index signal is extracted from the index phosphor.
LL circuit, and the output of this PLL circuit causes R. G. In a beam index type color television receiver in which a gate circuit for gating the B primary color signal is controlled so that the electron beam stimulates a desired color phosphor with a predetermined beam amount, the output of the PLL circuit is 1. A beam index type color television receiver, characterized in that a sufficient number of start index phosphor stripes for stabilization are provided at a horizontal scanning start portion outside the effective screen area of the phosphor screen.
