Abstract:
An apparatus for displaying video images, the apparatus comprising:cathode ray tube means including a electron gun system for producing at least one electron beam, which in response to a magnetic field converges the at least one electron beam onto a display screen causing video images corresponding to the at least one electron beam to be displayed thereon; and deflection yoke means for producing said magnetic field which includes a line deflection component and a field deflection component, the deflection yoke means comprising a plurality of electrical coils arranged such that the line deflection component is formed and the field deflection component is formed transverse to said line deflection component, the deflection yoke means further including at least one conducting plate having a length and having a rear end and a front end wherein said at least one conducting plate further comprises at least one slot oriented transverse to said length of said at least one conducting plate such that, when said at least one conducting plate is electrically energized, the magnetic field is enhanced.
