The meaning of LCD is “liquid crystal display” and Led is “light emitting diodes” . Technically, both “LED” and “LCD” are liquid crystal displays because  technology is the same in that both display  types have two layers of polarized glass through which the liquid crystals both block and pass light. So we can say that, LED  are a subset of LCD. LCD’s use CCFL (fluorescent) light source as their back light. LED LCD’s uses LED light source as their back light. CCFL (fluorescent) provides the LED LCD set better blacks, colors, contrast, and more even image across the panel.

The crystals do not produce any light as the light comes from a series of lamps at the back of the screen.

LED provide a better picture for two basic reasons. First, LED TVs work with a color wheel or distinct RGB colored lights (red, green, blue) to produce more realistic and sharper colors.

 The dimming capability on the back lighting in an LED allows the picture to display with a truer black by darkening the lights and blocking more light from passing through the panel. It has also meant that LED run with greater energy efficiency and can provide a clearer, better picture than the general LCD.
