[複製網址]
Display technology is different
LCD: A display screen consisting of liquid crystals.
LED: A display screen consisting of light-emitting diodes.

Display effect is different
LCD: Due to the backlight layer,lcd manufacturers, it emits light by refracting light, the color saturation is not so high, the display effect is more natural, and it is not easy to be tired after long-term viewing.
LED: It can emit light by itself, and each pixel can project the light of three primary colors of red, green and blue, so the display effect is more vivid and full.

different power consumption
  LCD: Turn on means that the entire backlight layer is turned on, and can only be turned on or off completely, which consumes a lot of power.
  LED: Each pixel works independently and can light up some of the pixels individually, so the power consumption of the LED will be lower.

different screen materials
LCD: Inorganic material, slow aging speed and long service life.
LED: Using organic materials, the life of the LED screen is not as good as that of the LCD screen.
