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

I know it's off the wall.

Not that off the wall though! All electronic equipment now has to ship
with a RoHS or WEE declaration, check it for the presence of mercury (Hg)
and if it's present, it's got a fluorescent backlight, if not then it's
another technology, almost certainly LED (although there are some TFT
panels with electroluminescent backlights, not sure how big they get
though).

Heh - Got news for you - 99% of ALL LCD monitors shipping today
(worldwide)
are RoHS compliant, have WEE declarations.... AND use CCFL backlights. Less
than 1% currently use LED technology.

The only way to check on backlight technology is looking for specifics by
the
monitor manufacturer. LED backlights are NOT common yet. If they are used,
it is more typically for performance reasons, such as wider color gamut, and
the extended life just happens to be an additional benefit.

I speak from experience.
