一、色纯余量的概念 我们在前面已经介绍过,对于任何类型的彩显管而言,色纯问题是第一重要的。只有达到了彩色纯净,才奶说明该管选色机构的作用是充分准确的,才能谈得到彩显管其它性能指标的考核。 通过“光透”的介绍,我们得到了一个概念,即要达到满屏色纯,关键是光透的设计和制作,要使得屏各处光线的入射方向与电子束的入射方向完全一致,粗看起来,似乎只要光透的制作符合要求,那么荫罩的色纯问题就介决了。因为静态色纯反正是可以调节的。然而问题并非如此简单。 First, the concept of color pure margin We have already introduced before, for any type of color tube, the color of the pure problem is the first important. Only reached a pure color, milk only shows that the role of tube color selection mechanism is fully accurate, can we talk about color tube performance indicators of other tests. Through the introduction of “light through”, we get a concept that to achieve full screen color purity, the key is the design and production of light through, so that the screen around the incident direction of light and electron beam incident exactly the same direction, thick It seems that as long as the production of light through to meet the requirements, then the shadow of the color of the pure problem solved. Because static color is pure anyway, can be adjusted. However, the problem is not so simple.
