Abstract: A shadow mask tube having such a distance between the shadow mask and the screen, that at least at the edge of the screen the average of the three distances from the centers of the phosphor dots associated with one mask aperture to the center of gravity of the triangle formed by said centers is at least 10% smaller than one third of the distance between two nearest phosphor dots of the same color.
