    摘要: A display apparatus includes a cathode ray tube. A deflection yoke is attached to the cathode ray tube. A deflection device serves to generate a sawtooth current in response to an input sync signal, and to feed the sawtooth current to the deflection yoke. A phase difference detector serves to detect a difference between a phase of the sawtooth current generated by the deflection means and a phase of a color pattern signal which represents a start and an end of luminance information in an input luminance signal. A correcting device serves to correct an image-indicated position in response to the phase difference detected by the phase difference detector.
