I've read somewhere that some new LCD monitors got their back-lighting
from LED arrays, rather than the useless fluorescence tube, and the
one uses LED arrays can last longer.

The thing is, when we go to buy LCD monitors, often there is no
indication which brand / model uses the fluorescence tube, and which
brand / model uses LED arrays.

There is an off the wall way to be offered only LED LCD monitors.

The mercury in fluorescence tube are a hazardous material, you can you
can turn green and demand only LED LCD monitors. Or require a MSDS for
each monitor

MSDS for Mercury

I know it's off the wall.
