The latest generation of LCD television technology is 40% more energy efficient models huge recent years. Samsung, Sony and Toshiba have submitted all models of TV with LED backlighting, instead of more power-hungry backlight CCFL used in previous years. To test the power consumption, Techtree.com made measurements on a 46 "LED TV using a power meter with different levels of energy efficiency. The power usage measuredranged from 72W and 116W depending on the level of energy savings. In contrast, LG 42 "plasma TV consumes between 150W and 255W depending on the Eco mode.

Samsung, calling the technology "LED TV", has been heavily criticized by competitors. The TV is LED backlit, LED TV is not a true as more advanced technology called Organic LED (OLED) TV. An OLED panel is constructed using different materials anddo not need a backlight; .. therefore very low power Pixels are made up of organic compounds that react to electrical current causing individual pixels of light on Sony introduced the first consumer OLED screen last fall, but the display measures only 11 inches and sells for $ 2,499. Sony can produce a model of stay-ups by the end of the year, but do not expect it to be accessible. A large screen OLED TV is several years away from mass consumption production.

In addition to the previously mentioned OLED technology, Sony Bravia LCD TV has an offer called. The Edge uses the Bravia LED backlighting, which means that the LED 's are mounted on the side rather than using an array of backlighting. In this way you get to the Bravia a very thin profile.

Toshiba offers LED-backlit arena is the REGZA SV670. This model includes a television company FocaLight Full Matrix> LEDs with local dimming, instead of the edge of LED lighting. In this way different groups of LEDs to be controlled independently, resulting in deep blacks without sacrificing the brightness peak. This TV seems to deliver a dynamic contrast ratio of 2,000,000:1.

In terms of footprint, there is still debate whether the LED backlight technology is better. LED backlit LCD TVs have a longer life and better efficiency thanother high-definition display. LEDs also do not use mercury, resulting in fewer problems with disposal TV. But they do use two undesirable substances, gallium and arsenic in the manufacture of LED emitters.
