What is the actual difference among CRT, LCD, LED?

CRT:

Pros: Extremely good color and great refresh rates.
Cons: Health (radioactive, Harmful), Expensive to work (draws a lot of power), Bulky.
Note: From various sources a lot of persons agree that the Sony SW900 is one of the best CRT and monitors of all time particularly for gaming. Even to this day, CRT definitely has it's play in many popular hearts.
Extra: For myself I never had a problem with CRT when playing games at a earlier age, in fact I hated the switch the LCD everywhere my teens and to me the image was poorer. Also in the last two years I feel my eyesight has somewhat reduced using LCDs. On the other hands it's the opposite for a lot of people, getting eyestrain and headache from CRT but this is mostly likely due to lambent or screen tearing since they run too low Mhz on the display frequency.

LCD ;
Pros: Cheap, Flexible, Reliable (lots of years put into change), Brighter then CRT (the lights might be what my eyes don't like, typically have the brightness unhappy to 0 depending on LCD).
Cons: i.e. hours in front of the desktop or going afk with the screen on (I guess sleep-mode prevents that), Not a very pleasant or realistic picture compared to good CRT or other monitors.
IPS: Extra mouth for LCD (don't exist on LED to my knowledge). Not sure how it works but has somewhat to do with switches and eventually gives a strikingly better image.

CRT: -
Pros:- Backlit (can eyestrain some individuals). Less control consumption then LCDs (credit to - amk-aka-phantom).
Cons: -Unlike a LCD your background can't get burnt into the screen BUT small adverts on the LED can die out giving you red or black marks at random spaces on the screen as it breaks down over time.
CCFL - Feature of LED.

Side note: Neither LCD or LED can burn a still image into the screen, that is only plasma TVs (credit to - cat’s-paw).

Will edit ANY CORRECTION on  this post and given credit for your contribution like I did to gold chain.
Btw, you don't have to reply to all of this, but causal what you can will make it a decent yarn over time.

As always, thanks in advance.
