The latest generation of LCD TV technology is a whopping 40% more energy efficient models of recent years. Samsung, Sony and Toshiba have all the TV models that uses LED backlighting, which replaces the more power hungry backlight CCFL used in previous years. To test the power consumption, Techtree.com performed measurements on a 46 “LED TV using a power meter, with different levels of energy savings. The use of power was one of the 72W and 116W depending on the level of energy savings. In contrast, LG 42 “plasma TV consummated between 150W and 255W depending on how Eco.
Samsung, called the technology “LED TV”, was heavily criticized by competitors. The TV is LED backlit, not a real TV LED as the most advanced technology called Organic LED (OLED) TV. An OLED panel is constructed using different materials and no need for backlighting, power therefore very low. The pixels are made of organic compounds that react to electric current that causes the individual pixels to illuminate. Sony has unveiled the first consumer OLED screen last fall, but the display measures just 11 inches and sells for $ 2499. Sony can produce a living size model by the end of the year, but do not expect to be accessible. A large screen OLED TV is several years away from mass production for consumers.
Besides the OLED technology, Sony Bravia LCD TV offering a called. BRAVIA Edge uses LED backlighting, which means that the LEDs are mounted on the side rather than using an array of backlighting. Ensure that the good can get a fairly subtle.
Offer Toshiba LED backlighting in-arena is the REGZA SV670. This model incorporates the company’s TV FocaLight Full Matrix LED with Local dimming, instead of edge LED illumination. This allows individual groups of LEDs to be controlled independently, to achieve deep blacks, without sacrificing the brightness peak. This TV seems to provide a dynamic contrast ratio of 2,000,000:1.
In terms of ecological footprint, there is still some ‘debate on the fact that the LED backlight technology is better. LED-backlit LCD TVs have a longer life and greater efficiency than other screens in high definition. LEDs also do not use mercury, resulting in fewer problems with disposal TV. They use a two undesirable substances, gallium and arsenic in the manufacture of LED emitters.
