					                        Why LED TV’s are better

The LCD TVs have CCFL (Cold Cathode Fluorescent Light) system which is not very energy efficient.
A single standard tube is used for backlighting in LCD displays and therefore you cannot control every
individual pixel. Consequently, the color and the contrast levels are somewhat affected. With LED
technology, the images literally dazzle with light and color. LEDs are quite different to standard
fluorescent backlight technology and they can even be turned on and off on an individual basis. But this
can prove to be a costly affair. But the fact remains that this technology can be used if the need arises.
Another major feature in LED TV's is the lack of mercury in the backlight. The LED technology TVs come
mainly in two styles, The dynamic RGB LED televisions that can be positioned right behind the panel, or
the others are white edge LED Televisions set around the outside of the screen which use special
diffusion panels to spread the light right across the screen evenly from behind the screen. LED TVs offer
a brighter picture while at the same time being able to produce a better contrast ratio. The result is a TV
that is slimmer with a picture that is brighter and darker at the same time. Clusters of LED lights can be
dimmed for an incredibly responsive display. But on the other hand, LED TVs are generally more
expensive than LCD TVs. In the end choose what, remains to be seen how much value your TV picture
quality.
