    • 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.
    • 显示装置包括阴极射线管。 偏转线圈连接到阴极射线管。 偏转装置用于响应于输入同步信号产生锯齿波电流,并将锯齿波电流馈送到偏转线圈。 相位差检测器用于检测由偏转装置产生的锯齿电流的相位与代表输入亮度信号中的亮度信息的开始和结束的彩色图案信号的相位之间的差异。 校正装置用于响应由相位差检测器检测到的相位差校正图像指示位置。
