Colour cathode-ray tube

本发明提供一种彩色阴极射线管。其中,荫罩(5)的多个孔列(15)的每一个具有:在垂直方向宽度较长的开孔(16)、在垂直方向宽度较短的开孔(17)、和在这些开孔之间的桥接部分(14)。在各孔列(15)中,交替配置1个长开孔(16)、和1或2个以上短开孔(17),短开孔(17)的水平方向最大宽度H#-[Smax]比长开孔(16)的水平方向基本宽度H#-[L]大。因此,不会产生莫尔条纹和颜色偏差、以及荫罩的断裂和颜色纯度偏差,可以提供辉度得到提高的彩色阴极射线管。 Each of a plurality of arrays of apertures 15 of a shadow mask 5 has...

Summary:本发明提供一种彩色阴极射线管。其中,荫罩(5)的多个孔列(15)的每一个具有:在垂直方向宽度较长的开孔(16)、在垂直方向宽度较短的开孔(17)、和在这些开孔之间的桥接部分(14)。在各孔列(15)中,交替配置1个长开孔(16)、和1或2个以上短开孔(17),短开孔(17)的水平方向最大宽度H#-[Smax]比长开孔(16)的水平方向基本宽度H#-[L]大。因此,不会产生莫尔条纹和颜色偏差、以及荫罩的断裂和颜色纯度偏差,可以提供辉度得到提高的彩色阴极射线管。 Each of a plurality of arrays of apertures 15 of a shadow mask 5 has a vertically long aperture 16, a vertically short aperture 17 and a bridge 14 between these apertures. In each of the arrays of apertures 15, one long aperture 16 and one or more short apertures 17 are arranged alternately, and a horizontal maximum width H Smax of the short aperture 17 is larger than a horizontal basic width H L of the long aperture 16. This makes it possible to provide a color cathode ray tube having an improved brightness without causing moiré fringes, color displacement, breaking of the shadow mask or variation in color purity.
