Abstract:
A video display apparatus using a linearity correction coil device, said apparatus comprising:a cathode-ray tube for generating an electron beam;a printed circuit board for said cathode-ray tube;a deflecting yoke for deflecting the electron beam; anda linearity correction coil device for compensating a linearity of the electron beam;wherein said linearity correction coil device exhibiting a central axis is installed on said printed circuit board for said cathode-ray tube, and wherein said axis of said linearity correction coil is equidistant at al points from a surface of said printed circuit board and is essentially parallel to the direction of the electron beam prior to deflection of said electron beam by said deflecting yoke, said linearity correction coil by a vertical length parallel to said axis and a horizontal length, said vertical length being shorter than said horizontal length.
