<p>In a vertical deflection circuit of a display monitor including a vertical deflection coil 41 and a sigmoid correction capacitor 42 connected to the vertical deflection coil 41, a series connection circuit consisting of a resistor 21 and a switch 22 connected in series with each other is connected in parallel with the sigmoid correction capacitor 42. By making the switch 22 on and off in response to a control signal having a period twice as long as a period of the vertical synchronizing signal, a current flowing through the resistor 21 and the switch 22 is periodically added to a vertical deflection current, thereby causing shift of displaying points on a screen to make the moire phenomenon unnoticeable. <IMAGE></p> |
