摘要： A color selection apparatus for a cathode ray tube includes an iron mask having a longitudinal axis and a short axis and a frame coupled with the mask and tensing the mask in one direction of the longitudinal and short axes. The mask includes a plurality of strips spaced apart from one another at predetermined intervals and a plurality of electron beam through holes formed by a plurality of real bridges arranged between the respective strips at predetermined pitches, wherein a center point of the mask along the longitudinal axis is A, both end points of the mask along the longitudinal axis are B, a length of a longitudinal side of the mask is 2L, point greater than L/4 from the point A in each direction are C, a tension applied to the strip of the point A is smaller than a tension applied to the strips of the points B and a distribution curve of a tension applied to the strips of the mask along the longitudinal direction satisfies the following equation; |SA-C|
摘要翻译：一种用于阴极射线管的颜色选择装置包括具有纵轴和短轴的铁掩模和与该掩模相结合的框架，并在纵轴和短轴的一个方向上拉紧掩模。掩模包括以预定间隔彼此间隔开的多个条带以及以预定间距布置在相应条之间的多个实桥形成的多个电子束通孔，其中掩模沿着纵轴的中心点是A，掩模沿着纵向轴线的两个端点都是B，掩模的纵向边的长度是2L，大于每个方向的点A的L / 4的点是C，施加到条带上的张力点A小于施加到点B的条带的张力，并且沿着纵向方向施加到掩模条的张力的分布曲线满足以下等式;其中SA-C表示直线的斜率将点A连接到张力分布曲线上的点C之一，并且SC-B表示在张力分布上将一点C连接到对应点B的直线的斜率曲线。
