LCD TV technology is miles ahead of typical box sets. They offer picture in high definition settings of both 720 and 1080 pixels and cost about 20 per cent less than competing LED flat-screen television sets, as of 2010. However, while these television sets enhance one's home entertainment, they do present certain health and environmental hazards.

LCD television sets contain mercury. This can lead to health risks if the unit is dropped and breaks open. Mercury and its components are toxic and can enter the body through the skin or through inhalation, states the Global Healing Center website. Exposure to the element can lead to mercury poisoning, which can lead to kidney, spleen, brain and liver damage. It can also be harmful to developing foetuses.
In April 2009, the U.S. Consumer Product Safety Commission (CPSC), along with the retailer, announced that certain models of Insignia LCD sets were recalled and taken off store shelves. The televisions' power supply was prone to failing and shutting off, causing fire and burn hazard to consumers.
LCD TVs have proved to contain nitrogen trifluoride, or NF3. According to Greenzer, an environmental awareness website, this is a pollutant that was originally created to eliminate the use of ozone-damaging fluorocarbons. However, this turned out to be 17,200 times worse to the environment than carbon dioxide. Although some manufacturers have adjusted their methods, NF3 is still a key component in creating LCD sets for many companies.
