Samsung to make more energy-efficient LED TVs

Samsung Electronics Co Ltd on Wednesday showed off a new line of high-
end, ultra-slim, energy-efficient televisions and said it planned to
increase the proportion of TVs it makes using LED technology.

I hope they don't look like my LED laptop display. The LED back-light
looks much hotter (very bluish) than my other fluorescent laptops. I had
to fiddle a lot with the colors to reduce the eye strain.

Unfortunately, any random LCD TV BLU (Back Light Unit) is apt to be
using "white light" LEDs and not an array of R-G-B LEDs. White light
LEDs commonly use a blue LED to drive them, and phosphor to
down-convert some of the energy to other colors.

This results in a crappy spectrum that is blue-heavy, and may even be
medically hazardous (just due to blue - not to mention UV). If the TV
maker won't tell you what kind of LED(s) they are using, doesn't
want to talk about the spectral curves, and fails to mention %NTSC,
you may presume the BLU is suboptimal.

LED BLUs, alas, are now trendy due to being "greener" power wise,
and avoiding the politically symbolic but practically inconsequential
amount of unbound Hg in CCFLs. As Apple has already shown with
a low-end LED BLU LCD, LED BLU does not automatically result in
DCI compliance.
