text: LCD uses a liquid crystal to produce a visible image.
text: LCDs use liquid crystals that twist and untwist in response to an electric charge and are lit by a backlight.
text: LCD (liquid-crystal displays), OLED (organic light emitting diode) and MicroLED displays are not quite the same, since LCD uses a liquid crystal that reacts to an electric current blocking light or allowing it to pass through the panel, whereas OLED/microLED displays consists of electroluminescent organic materials (that include carbon, thus the name

text: One of the major difference between the LED and the LCD is that the LED uses the PN-Junction diode which emits light when the current passing through it, whereas LCD uses liquid crystal or plasma for visible light emission.
text: The LED uses gallium arsenides which when heated emits light whereas LCD uses liquid crystals which are energised and provides light.
text: LCDs use these liquid crystals because they react predictably to electric current in such a way as to control light passage.
