Abstract
A vertical deflection circuit includes a vertical deflection coil; a vertical deflection circuit for supplying an vertical deflection current to the vertical deflection coil; a current multiplying circuit multiplying a predetermined current upon the current flowing through the vertical deflection coil in an even field or an odd field of a television signal; and the raster of the even field and the raster of the odd field coinciding with each other.
Claims10
A vertical deflection circuit, which comprises:
- a vertical deflection coil;
- vertical deflection current means for supplying a vertical deflection current to the vertical deflection coil;
- and
- current source means for selectively imposing a predetermined current upon the vertical deflection current thereby increasing the current flowing through the vertical deflection coil in either an even field or an odd field of a television signal;
- wherein the raster of the even field and the raster of the odd field coincide with each other by the selective imposition of the predetermined current.
A vertical deflection circuit for conducting a non interlacing scan of a display, causing odd and even fields of the display to coincide, comprising:
- a vertical deflection coil;
- first means for supplying a vertical deflection current to said vertical deflection coil;
- and
- current source means for selectively applying a second current to said vertical deflection coil, said current source means applying said second current to said vertical deflection coil in either said even fields or said odd fields, said second current combining with said vertical deflection current so as to deviate a raster in the fields in which the second current is applied.
