LCD :-
It is perhaps the most popular term we see in the market.
LCD stands for Liquid Crystal Display. Usually a standard LCD screen comes with
a fluorescent backlight, which is responsible for illuminating the glass screen
so we can see the content.
The big problem is that the LCD cannot produce perfect
blacks, since the backlight would have to completely shut down to get there.
Moreover, one of the great advantages introduced, was how thin are compared
with older screens
LED :-
This stands for Light Emitting Diode, or Light Emitting
Diode Spanish. Quite the opposite of what people might think, the "LED
screens" are also LCD screens. The difference is that we change the
fluorescent backlight LED backlight.
The great advantages of this technology are its much lower
energy consumption and allowing greater thinness mentioned above. But most
important is that we get much closer to a true black color, because if the LCD
panel is turned off, the LED backlight can obscure the necessary areas to reach
black
