要了解彩色电视机怎样工作,就必须回溯到早期颜色的发现上。你知道为了画一幅画你所必需的东西是三原色,即:红、蓝、黄.它们可被混合调制成任何一种其他颜色。同样,如果你用放大镜认真观察杂志上的彩色照片,你就会看到它是由三原色再加点黑色构成的无数小圆点,如果你更近一点观察电视画面,你会看到它也是以同样的方法构成的。只有一点不同——这三种颜色是红、蓝、绿。

If you look closer at the TV screen, you will see that it is the same. The method consists of. Only one difference - the three colors are red, blue, and green.
