PROBLEM TO BE SOLVED: To provide a display correction device for detecting high voltage fluctuation in full-white display and full-black display, making the phase of horizontal drive output signals fluctuate and correcting the fluctuation of the horizontal position of display as well. SOLUTION: Horizontal amplitudes in the full-white display and the full-black display are made the same by a horizontal amplitude correction circuit 5 for correcting the horizontal amplitude by the information of the detection signals of a high voltage fluctuation detection circuit 4 for detecting the fluctuation of a high voltage. Further, horizontal phases are corrected by a horizontal phase correction circuit 6 for correcting the phase of the horizontal drive output signals by the detection information of the high voltage fluctuation detection circuit 4 and the horizontal positions are made the same in the full-white display and the full-black display. |
