How does CRT work?

The CRT consists of numerous electron beams. Whether interlaced or non-interlaced, they move across the screen. 

There are millions of phosphor dots in a CRT monitor which glow when hit by the electron beams. This clash between the two accelerates deflects and modulates the electron beams on the screen to create visible images.
