What is 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 recording to the instructions. So you’re saying, “that’s great so why do we see the stuff we do”. Well, then the electrons hit the screen, they react with a chemical surface made of phosphors. The reaction of the electrons with the phosphors 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.
 
 
 

The disadvantage of Using CRT as Monitor:

With a 100-year head start over competing for screen technologies, the CRT is still a formidable technology. It’s based on universally underscore principles and employs commonly available materials.
The result is cheap-to-make monitors capable of excellent performance, producing stable images in true color at high display resolutions.
 
 
 
However, no matter how good it is, the CRT’s most obvious shortcomings are well known:
  • It Stuck up too much electricity.
  • Its single electron beam design is prone to misfocus.
  • Misconvergence and color variations across the screen.
  • Its clunky high-voltage electric circuits and strong magnetic fields create harmful electromagnetic radiation.
  • It’s simply too big.
