Abstract

PURPOSE: To ensure the accurate color reproduction even though the index signal stops by holding forcedly the frequency of the output signal of the PLL circuit at the frequency of the time when the index signal stopped for the period when the index signal stops.
CONSTITUTION: Index signal S1 is supplied to PLL circuit 42 while electron beam 14 scans the effective screen part which is formed by arraying the red, green and blue color fluorescent stripes R, G and B in sequence and in the horizontal scanning direction on the panel inner surface of color picture tube 4. The color synchronization is secured by output signal SL of the PLL circuit. In the period when signal S1 is stopped, circuit 42 is locked again after passing instantaneously the state under which circuit 42 oscillates with the self-running frequency. In such way, the correct color reproduction is ensured even after resetting.
