LED backlight - TV is Going Green

LED TV


The latest generation of LCD TV technology is a huge 40% more efficient than last years models. Samsung, Sony and Toshiba have all the lights in the background introduced the TV using LED instead of CCFL backlight power hungry several years used in previous years. To control, energy consumption, measures Techtree.com on a "46 LCD TV with a power meter with power saving settings. The energy consumption measuredranged from 72W and 116W depending on the level of energy savings. In contrast, LG 42 "plasma TV mode consumes between 150W and 255W depending on the Eco.

Samsung, the technology called "LED TV", has been heavily criticized by competitors. The TV is equipped with LED backlighting, LED TV is not real as the most advanced technology called Organic LED (OLED) TV An OLED panel. Using various materials andthere is no need for backlighting, power consumption very low. Pixels are organic compounds, the electric current causes each pixel of light made you react. Sony launches the first consumer OLED screen last fall, but the display measures only 11 inches and sells for $ 2,499. Sony could be a living model enterprises 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 market Production.

In addition to the above OLED technology, Sony has a service named Bravia LCD TV. Use the Bravia Edge LED backlight, so that the LEDs are mounted to the series on the page, instead of a backlight. In this way, the Bravia is a very thin profile to be achieved.

Toshiba offers LED-backlit Arena is the REGZA SV670. The TV model incorporates the company FocaLight Full-matrix> LEDs with local dimming LED backlighting instead of the edge. In this way different groups of LEDs are controlled independently to achieve deep blacks without a peak brightness. This TV is obviously deliver a dynamic contrast ratio of 2,000,000:1.

In view of the ecological footprint, there is still some debate as to 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, thereby reducing the problems with TV are available. But they are two spots with undesirable substances, gallium and arsenic in the manufacture of LEDs.
