1. video display deflection device comprises:

  • First deflecting coil of saddle type, described first deflecting coil produces deflection field, so that electron beam is along first scanning of crt display screen, described first deflecting coil comprises a pair of lateral section of formation, rear end wire turn a plurality of winding wire turns partly near described fluoroscopic front end wire turn part and approaching described pipe electron gun, described lateral section is formed in the winding window that does not have lead therebetween, limit the length dimension of this window by the distance between described front end wire turn part and the described rear end wire turn part, at least one described lateral section is useful on first winding space of correcting electronic beam-landing screen error, described first winding space is having first bight from being about near the along slope coordinate of described window first end of described rear end wire turn part and the position of more approaching to select in the along slope coordinate scope between the described fluoroscopic along slope coordinate, the distance of this scope be approximately described window described length 10%;

    Second deflecting coil, be used to make described electron beam along described fluoroscopic second scanning to form grating;

    WithCan ooze the magnetic core of magnetic, constitute deflection system with described first and second deflecting coils.
