It turns out HDTVs are a bit hazardous to our health, well eventually. Actually, it turns out, all flat-panel displays aren't so great.
LCD panels actually use a deadly gas called Nitrogen Trifluoride when in production. When inhaled the gas is extremely harmful to your kidneys and liver.
When it starts being released into the environment is about 17,200 times worse than carbon dioxide. Which means it will end up trapping heat into our atmosphere over a hundred year period. Hopefully they will fix this issue so I can have an HDTV at least mostly guilt free.
