The latest generation of LCD TV technology is the energy of a whopping 40% more than last year, one of the efficient models. Samsung, Sony and Toshiba have introduced all models of TV use LED backlighting instead of the more power hungry backlight CCFL used in previous years. To test the power consumption, Techtree.com measurements made on a 46 "TV with a LED power meter, with different levels of energy saving. The power dissipation of 72W and116W, depending on the level of energy. In contrast, LG 42 "plasma TV consumes between 150W and 255W depending on how Eco.

Samsung, called LED technology, "TV", was heavily criticized by competitors. The TV is equipped with LED backlighting, not a real TV LED as the most advanced technology called Organic LED (OLED) TV. An OLED panel is constructed with different materials and there is no need for backlighting, power consumption in very low. The Pixels are organic compounds, causes electrical current to illuminate each pixel. Sony made the first response of consumers OLED display was introduced last fall, but the screen measures just 11 inches and sells for $ 2499 Sony can produce a model of lifetime this year, but do not expect them to be accessible. A large screen OLED TV is several years from mass production for consumers.

In addition to the above OLED technology, Sony has a LCD --> Offer named Bravia TV. The Edge LED-backlit Bravia set, which means that the LEDs are mounted on the side and not with an array of backlighting. Otherwise, the good you can get a fairly thin.

Offer Toshiba LED-backlit display in the arena is the REGZA SV670. The model includes TV FocaLight company Full Matrix LED local dimming LED backlighting instead of onboard. This allows different groups of LEDs are controlled individually,without depth of blacks to reach peak brightness. Television is, of course, provide a dynamic contrast ratio of 2,000,000:1.

In view of the ecological footprint, we are still debating whether the technology of LED backlighting is better. LED-backlit LCD TVs have a longer life and greater efficiency than other screens in high definition. LEDs do not use too much, not mercury, the problems with less TV. But they do it with two undesirableMaterials, gallium and arsenic in the manufacture of LED emitters.
