The world of television has began to see the appearance of LED Technology used in lighting LCD displays rather than the traditional fluorescent lighting that has been used up to now. With it, LEDs bring a range of improvements that are enhancing the viewing experience of consumers.
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.
For this reason Britain?s Advertising Standards Authority questioned some of the marketing associated with LED TVs. The ASA pointed out that using LED TV to describe these new models was misleading as they are essentially still LCD TVs. The result of this was clarification was made to point out that LEDs are used to light these screens. Some manufacturers have also pointed out that a more accurate description would be to call them LED-lit LCD TVs.
At this point Samsung, Sony, Philips and LG have their own variations of LED televisions on the market. All have their own unique features and the result is that the new TVs produce a better picture quality, are thinner, lighter and are more energy efficient. On the down side as is to be expected with new technology, they are still more expensive than standard LCD TVs.
The LEDs are used in either side-lit or back-lit arrangements in LED TVs. Edge-lit LED TVs as the name would suggest use LEDs round the side of the LCD display. The TVs can be made much slimmer because LEDs take up less space than the fluorescent lights they replace. Back-lit LED TVs are not quite as thin but have the added benefit that the LEDs can be locally dimmed to produce better contrast with darker blacks. LED TVs can be made as little as 10mm thin.
With LED lighting picture quality is further improved because LEDs have a fuller spectrum range of light than fluorescent lights do. This has the benefit of improved contrast and enhanced color reproduction.
All forms of LED displays that utilize LEDs for lighting also benefit from improved lifespan. Fluorescent lighting does not last as long as LEDs. Over time fluorescent lights degrade and the LCD display becomes duller. Once this happens the lights can?t be replaced, it usually takes 3-4 years to become noticeable.
One last thing, as the marketers will tell you, if you want to do your bit for the planet then buying an LED television will ease your consciousness. The marketers claim they are considerably more power efficient than older LCD sets. Also some of the hazardous materials used in the design of fluorescent lit sets have been eliminated by the introduction of LEDs. - 29854
