ABSTRACT:
A cathode-ray tube has a faceplate panel joined to a funnel. An internal magnetic shield is disposed within the tube and is connected to a bottom surface of a flange of a shadow mask frame. The flange of the shadow mask frame has a plurality of integral shield-retaining clips formed therein. Each of the clips overlaps at least a portion of the shield, to retain it in contact with the flange of the frame.
