LCD (Liquid Crystal Display)
LCD refers to a flat panel technology which uses liquid crystals in TVs, computer monitors and other types of displays. This type of panel consists of crystals suspended in liquid which function as an \electronic shutter\, allowing the crystals realign themselves to let light pass through. The amount of power applied determines the amount of realignment and how much light is let through. Unlike OLEDs, which produce their own light, LCD TVs require a light source, such as an edge-lit or full array LED backlight unit to create the light needed to display an image.
