Don?t be fooled by the terminology that manufacturers are using to describe it. Though there are definite benefits to be had, LED TV is simply an LCD television that uses LEDS as its light source. The LEDs are what have brought about the improvements, replacing the inferior fluorescent lighting that has been used in LCD televisions up to this point.
The use of the phrase LED TV has come under some scrutiny. In the GB the ASA was critical of the use of the phrase and said it was misleading to consumers. It indicates that LEDs are more significant than they actually are. In the end manufacturers agreed that they would make the function of LEDs in these televisions clearer in their advertising. Other makers of TVs indicated a better description would be to call such displays LED lit LCDs.
You will currently find LED televisions and displays being produced by JVC, Samsung, Sony and Philips. They will all claim that LEDs are advancement on previous LCDs. To summarize they allow today?s displays to be manufactured lighter, slimmer, eco-friendlier and of course improved images. Because they are new to the market they are however still quite expensive when compared with standard LCD displays.
In LCDs televisions and displays up to this point, the lighting was provided by fluorescent strips. Replaced by light emitting diodes, screens can now be manufactured to produce some of the slimmest sets we have ever seen. Sony has a model that is a mere 10mm at its thinnest point. Samsungs sets measure about 3cm in thickness. Both a big improvement in what we have seen on the market up to now. With LED TVs individual LEDs can be controlled, we are seeing improved contrast controls meaning the levels of lightness and darkness are much brighter and darker.
The colours are claimed to be further enhanced with LED lighting. This can be explained by the fact that LEDs produce a full spectrum of light when compared to fluorescent lights. The contrast control is also improved.
One major negative with fluorescent lit LCD displays was that over time (typically over 3-5 years) the fluorescent lights would fade. As modern electronics are not design to be repaired, when this occurred there wasn?t much the consumer could do other than buy a new set. This throw away nature is still no different, but the life span of LED TVs has been improved as the fluorescent lights are no longer required and LEDs are more reliable in this respect.
In a world that is becoming ever greener, LED TVs are doing their little bit. They are more eco-friendly than older LCD TVs. This is because of the improved efficiency of LEDs. Manufacturers will claim that LED TVs use up to forty percent less energy than standard LCD displays and even more when it come to plasmas. Another point worth mentioning is that fluorescent lighting contained mercury which has obviously been eliminated.
