摘要： An internal magnetic shield reduced in mistaken landing length due to distorted electron beams by the external magnetic field of geomagnetism or the like, and also reduced in color misregister and color unevenness. The internal magnetic shield is provided with at least one skirt unit (37) in an externally square tube shape having a plurality of side surface and extending from a non-contact portion with a holding member (42) up to the vicinity of a tension member (41), the skirt unit (37) being magnetically coupled with the tension member (41) constituting a mask frame.

摘要： Die Erfindung betrifft eine Farbbildröhre und ein Herstellungsverfahren für eine Farbbildröhre. Die Farbbildröhre enthält eine Schattenmaske (10), die an einem Maskenrahmen befestigt ist. Zur Verbesserung der Abschirmwirkung ist an zumindest einem Längsholm (11) des Maskenrahmens ein Abschirmblech (20;60) befestigt, das äußere Magnetfelder abschirmt. Mit einem solchen Abschirmblech lässt sich die Bildqualität einer Farbbildröhre verbessern und der Herstellungsaufwand gegenüber herkömmlichen Farbbildröhren vereinfachen.

摘要： An image display device comprises a faceplate (10) having an image display surface and a rear plate (12) opposed to the faceplate (10) across a gap and having a plurality of electron sources which excite the image display surface. A grid (24) and a plurality of spacers which maintain the space between the plates are provided between the faceplate (10) and the rear plate (12). A voltage from a voltage supply unit (50a) that is higher than a voltage applied to the faceplate (10) is applied to the grid (24), so that electric discharge can never be caused directly between the faceplate (10) and the rear plate (12).

摘要： A color display tube with an elongated phosphor screen having a pattern of discrete phosphor elements. In order to reduce landing errors of the electron beams (5, 6, 7), in particular in the X direction, and simultaneously minimize the amount of magnetic material used for the internal magnetic shield, the color display tube has an internal magnetic shield (16) consisting of a tub that is deep-drawn from a foil, which tub has a bottom (21) with an aperture (22) for allowing passage of electrons. Material of the bottom adjoining the aperture for allowing passage of electrons has been bent outwards from the plane of the bottom. In this manner, material of the bottom of the tub which would otherwise have been cut away is used to enlarge the 'virtual' height of the magnetic shield.
