What is the full form of CRT
CRT: Cathode Ray Tube
CRT stands for Cathode Ray Tube. It is a vacuum tube containing one or more electron guns and a phosphorescent screen, which is used in traditional computer's display and in Television. It works by moving electrons from the back of the tube towards the display screen where it collides with the phosphorous. When the electrons hit the phosphorous, they light up and are projected on the screen.
The colour shown on the screen is produced by three lights Red, Green and Blue and often referred to as RGB.
When a speaker or other magnetic devices are kept close to a CRT monitor, interference is produced.
This is due to the Magnetic charges which guides the way of electrons. LCDs and flat screens don't face this problem as they don't use magnetic charges. Tube is also absent, due to which they look much thinner than CRT monitors. LCD display is almost matchable with the quality of CRT monitors which is why they are replacing them from both consumer as well as professional market.
