Difference between LCD and LED TV

When looking for a new TV to buy, it might be confusing to have to decide between an LCD TV and an LED one. The latest TVs in the market have a lot of features that make it really difficult to choose. This article will help you choose between an LCD and LED TV by looking at the differences between these two types.



A LCD TV is a flat-panel TV that uses Liquid Crystal Display technology to display pictures. The liquid crystals are held together by a layer of glass and are responsible for producing images by regulating light from fluorescent lamps at the back of the TV.

A LED TV, on the other hand, is also a flat screened TV working on the same liquid crystal display technology, but instead of the liquid crystals getting their light from fluorescent lamps, they get it from Light Emitting Diodes.

What is the difference between LCD and LED TV? The difference between these two types of televisions is the type of light source used in them.

Both LCD and LED TVs are flat-panel televisions that utilize liquid crystal display technology. The TVs have two layers of glass that are polarized and stuck together. The liquid crystals are sandwiched between one of the layers of glass. When electric current is passed through the liquid crystals, they regulate the light by letting some of the light pass while blocking some of it to produce images.

Since the crystals do not produce light, the light has to have a separate source. This is where the difference between an LED and LCD comes in. For an LCD TV, the light comes from fluorescent lamps at the back of the television, whereas for an LED TV, the light is produced by diodes – hence the name LED (light emitting diodes). An LED TV is an LCD TV since it uses liquid display technology but the difference is in the source of light used. LED TV is the newest technology of the two, with a newer backlight system made from diodes that consume less power. This makes it a little more expensive than an LCD TV.
