Abstract

PURPOSE: To obtain correct index information, by dividing the index signal with the density modulation signal of electron beam and performing color selection with the output.
CONSTITUTION: The color fluorescent substance stripes R, G and B (red, green and blue) are sequentially and repetitively arranged internal the panel toward horizontal scanning, and also, the index fluorescent stripe is arranged toward horizontal scanning. The index signal obtained by scanning the flourescent substance stripes by the electron beams 12 of the receiving tube 11 is divided 22 with the density modulation signal, and color selection can be made with the control from the divided index signal. Thus, the index signal corrected, which is obtained from the division circuit 22, has almost a constant level because of removal of the effect by the density modulation signal, and correct index information can be obtained.
