CRT Monitors
This is a typical CRT monitor.
CRT or Cathode Ray Tube monitors are composed of an "electron gun"
and a specially coated screen. When the monitor receives the instruction
from the video adapter, the electron gun "shoots electrons" onto the screen
according to the instructions. So your saying, "that’s great so why do
we see the stuff we do". Well, when the electrons hit the screen, they
react with a chemical surface made of phosphors. The reaction of the electrons
with the phosphors produces a small glow. The combined glow of the entire
screen produces the visible image. The beams of electrons generally travel
across the screen in a vertical manner.
