LED HD TV

By Paul Harrison

LED TVs and displays employ a new technology which a have improved the viewing experience. They have now been made thinner, lighter and have a better picture quality than their conventional LCD counterparts. The advances in this area resulted in Samsung selling approx one million LED TVs worldwide in the first six months.

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.

The use of LEDs is to provide the lighting which was formerly provided by fluorescent lights. They can be side or back lit. Side lit LED TVs can be made to be very thin, the thinnest on the market are only 1cm thick. Back lit displays aren?t far behind and have the advantage of improved contrast level. This because the LEDs which are situated behind the display can be individually controlled, this enables the TVs to produce very dark blacks by turning off the corresponding back-light LEDs.

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.

LED monitors as well as TVs have extended life expectancy with the introduction of LEDs technology. LEDs have a longer lifespan than fluorescent lights and, as LCD TVs are not designed to have the fluorescent lighting replaced when the backlight begins to dim or fails then there is little that can be done.

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. - 32388
