But, they use raster scanning too, updating the brightness of little tiny red, green and blue pixels many times a second.

但是，他们也使用光栅扫描，每秒多次更新微小的红色、绿色和蓝色像素的亮度。

If the graphics card saw the 8-bit code for the letter " K" , then it would raster scan the 2D pattern for the letter K onto the screen, in the appropriate position.

如果显卡看到字母“K”的 8 位代码，它就会将字母 K 的 2D 图案光栅扫描到屏幕上的适当位置。
