Abstract
A cathode-ray tube has a faceplate panel joined to a funnel thereof along a sidewall of the panel, and has an internal magnetic shield disposed therein proximate an inner surface of the funnel and connected along one end thereof to a back portion of a shadow-mask frame oriented orthogonally to a central axis of the tube and supported adjacent the sidewall. An apertured shadow mask is connected along an edge thereof to a front portion of the shadow-mask frame opposite the back portion. Along the direction of the central axis, the one end of the magnetic shield overlaps the corresponding edge of the shadow mask around substantially all of the shadow-mask frame.
