Abstract
PURPOSE: To enable to perform stable color synchronism, by making the circuit characteristics, when electron beams scan the horizontal scanning start section and the effective picture section.
CONSTITUTION: The effective picture section 6 is formed by repetitively and sequentially being arranged toward horizontal scanning for the color fluorescent substance stripes R, G and B (red, green and blue) internal the panel, and the index fluorescent substance stripe 11 is arranged toward horizontal scanning over the effective picture section 6 and the horizontal scanning start section 9. Then, the index signal obtained by scanning the stripe 11 is fed to the PLL circuit 40, color synchronism is taken with the output signal of the circuit 40, making different the characteristics of circuit for the scanning of the initiation section 9 and that of the screen section 6 by electron beams. Thus, at the initial of horizontal scanning, the circuit 40 is quickly locked resulting that the circuit 40 does not respond to the frequency variation of index signal of the picture section 6. Thus, stable color synchronism can be performed.
