Apparatus for displaying video images

摘要

An apparatus for displaying video images. A video image display apparatus including a cathode ray tube device for producing a plurality of electron beams each corresponding to a respective color and, in response to a magnetic field, for converging the electron beams onto a screen of the cathode ray tube device so as to cause video images corresponding to the converged electron beams to be displayed thereon. The apparatus further includes a deflection yoke device for producing the magnetic field. The deflection yoke device is arranged such that an inner surface thereof is adjacent to an outer surface of the cathode ray tube device. The inner surface of the deflection yoke device has a predetermined contour such that a distance between the outer surface of the cathode ray tube device and the inner surface of a middle portion of the deflection yoke device is substantially larger than each respective distance between the inner surface of both end portions of the deflection yoke device and respective adjacent parts of the outer surface of the cathode ray tube device.
