DEFLECTION YOKE AND CRT DEVICE USING DEFLECTION YOKE

摘要

PURPOSE: A deflection yoke and a CRT device using the deflection yoke are provided to reduce power consumption without sacrifice of convergence performance as much as possible. CONSTITUTION: A deflection yoke(24) mounted around a glass bulb(20) of a CRT covers a predetermined area of the glass bulb, the predetermined area being where an outer shape of the glass bulb smoothly goes from circular to substantially rectangular along a tube axis of the CRT, and comprises a horizontal deflection coil disposed in a shape to fit with the outer shape of the glass bulb, and a funnel-shaped ferrite core disposed to surround the horizontal deflection coil, an inner shape of the ferrite core being circular throughout a length of the ferrite core.
