Are you in the market for a new flat screen television? Maybe your old TV has finally stopped working or perhaps you just decided it is time to upgrade. The first thing you need to know is that flat screen TVs come in three different types: Plasma, LCD and LED. You may not be able to see much of a difference between the three from the outside (when not switched on), but inside they all work very differently.

For example, LCD and Plasma televisions both use a fluorescent system to light the screen. The problem with this is that sometimes light leaks around the crystal diodes inside which turns the blacks on the screen to a dark gray. This effect is caused by the fluorescent tubes always being powered on. The end result is a slightly fuzzy looking image when viewed by the human eye.

The liquid crystal diodes in the tubes are technically capable of producing an unlimited variety of color, however this often does not come through in LCD and Plasma televisions because the fluorescent lights themselves are not of high enough quality. A backlit LED TV is capable of a much wider and richer range of color, this is where LED style televisions have the edge over Plasma and LED.

LED TVs have two different set-ups when it comes to back-lighting. Some LED TVs have a completely back-light behind the screen while others have them placed around the edges. Both of these set-ups consume less electricity than the fluorescent systems used by LCD and Plasma TVS, but they do have their own draw-backs.

LED TVs with edge lighting are light-weight and thin, but the lights are always on just like fluorescent systems and despite the fact they use diodes to create light the black colors on the screen are still not as deep and rich as backlit LED sets. The backlit models have that sharp, rich black color but they are not as thin as the edge lit models. But when it comes to having to absolute best, sharpest image a backlit LED TV is definitely the way to go. It is the prime choice of many serious TV and movie watching consumers.
