    Abstract: A cathode ray tube having a tensioned shadow mask with elongated holes, i.e. holes with a length longer than 5 mm. The pattern of holes repeats itself after 5 or more rows and the relation between the number of rows after which the pattern repeats itself, the vertical pitch av and the horizontal pitch dh is given by av/dh≦n2≦8av/dh, most preferably n2≈2av/dh.

    Abstract translation: 一种阴极射线管,其具有带有长孔的张力荫罩,即长度大于5mm的孔。 在5行或更多行之后,孔的图案自身重复,并且其中图案重复的行数,垂直间距av和水平间距dh之间的关系由av / dh <= n2 <= 8av / dh给出, 最优选n2≈2av/ dh。
