LCD
a) LCD stands for Liquid Crystal
Display which is a thin, flat display
screen made up of any number of
color or monochrome pixels
arrayed in front of a light source
or reflector.
b) It is often used in electronic
Devices because it uses very small amounts of electric power.
LED
a) LED stands for Light
Emitting Diode which is a semiconductordiode that
emits incoherent narrow-
spectrum light when
electrically biased in the
forward direction of the p-n junction. This effect is a
form of electroluminescence.
b) It can be used as a
regular household light
source.
CRT
a) CRT stands for Cathode
Ray Tube which is a tube
coated with phosphorous in
inner surface. When electrons
produced by e-gun come in
contact with phosphorous
wall, light is produced by
virtue of which we can see.
b) It is generally used
in TV scrreens, monitors, etc

LED stand for Light Emitting Diode. It is the most modern type of monitor.
LDC stands for Liquid Crystal Display. It is relatively older than LED.
CRT stands for Cathode Ray Tube. It is the oldest type of Monitors.
please mark me as the brainliest!!!
