Abstract
PURPOSE: To correct a distortion of raster, by providing a protruding piece of magnetic unit, facing the deflecting yoke side, in a position corresponding to the picture tube face diagonal at rear end of the funnel shield plate.
CONSTITUTION: To the funnel of a cathode-ray tube 2, to which a deflecting yoke 3 is mounted, is installed a shield plate 8. In rear end of the shield plate 8, in a position corresponding to the diagonal of the picture tube face, that is, from a position corresponding to four corners of the picture tube face to a position coming near the front portion of the deflecting yoke 3, is constructed a protruding piece 9. The protruding piece 9 is constructed by a magnetic unit. In this way, the protruding piece 9 inducing a magnetic flux generated in the front portion of the deflecting yoke and controlling the magnetic field wholly into the pincushion shape, the raster is made into a barrel shape, and a distortion of the raster can be corrected.
