LCD (Liquid Crystal Display) is a thin and flat display device made up of a number of color or monochrome pixels arrayed in front of a light source or reflector. Recently, this LCD technology has become a widely used method in the manufacturing of television. Over 45% of televisions sold around the world so far in 2008 have been plasma and LCD TVs. However, scientists are ready to ring warning bells that this boom can be a serious problem for the environment.
Factor That Makes LCDs Eco-Enemies:
A gas used in making of flat screen televisions, Nitrogen Trifluoride (NF3) is 17000 times as powerful as Carbon Dioxide. NF3 is not covered by the Kyoto protocol because it was only produced in small amounts in 1997. Professor Michael Prather from the University of California has highlighted this issue in an article for the magazine ‘New Scientist’.
Studies Say:
Professor Michael Prather estimates 4,000 tons of NF3 will be produced in 2008 and that number is likely to double in 2009. Dr Paul Fraser, the chief research scientist at the CSIRO’s marine and atmospheric research centre and an IPCC author, says without measuring the quantity of Nitrogen Trifluoride in the atmosphere it is unclear what impact it will have on the climate. He explained further, that they haven’t observed NF3 in the atmosphere or probably it’s in very low concentrations. Dr Fraser concluded, the key to whether it is a problem or not depends on how much NF3 is released into the atmosphere.
LCD televisions and computer monitors are widely used by which the emission of dangerous gases into the atmosphere is also being increased. We only hope the best that these LCDs choose an alternative for the NF3 used to design flat screen televisions.

Its cool article. I think writer selected a good topic. Nice work work done.
