Abstract:
A cathode ray tube apparatus comprising:a substantially rectangular face panel having a phosphor screen on the inner surface thereof; a funnel connected to the face panel; an electron gun structure configured to emit electron beams toward the phosphor screen; and a deflection yoke mounted on the outer surface of the funnel and configured to generate a deflecting magnetic field for deflecting the electron beams emitted from the electron gun structure, the deflection yoke including a horizontal deflecting coil for deflecting the electron beams in a horizontal direction, the horizontal deflecting coil having a main coil portion located along the direction of a tube axis, a flange portion located on the phosphor-screen side of the main coil portion, and a bendless flange portion located on the neck side of the main coil portion, the maximum coil thickness of the neck-side flange portion being greater than the maximum coil thickness of the main coil portion near the neck-side flange portion.
