Absolutely true, except that this particular TV doesn't use white LEDs in
its 'revolutionary' backlighting scheme. It uses small RGB arrays, which is
why I was questioning whether there was any control over the individual
elements in each array, such that the colour temperature of the nominally
white light that they produce, could be varied. Which would then, of course,
have a corresponding effect on the displayed colour balance. It just seemed
to me that given they have gone to the trouble of using RGB arrays, rather
than white LEDs, the reason for that might have been to get a full(er)
spectrum white.

colour temp can be controlled using the LEDs or the LCD, I'm not sure
it makes any big difference which one.

RGB LEDs would give the same white as a triphosphor&uv white LED, but
with more colour control. The standard 2 colour white LED would be
useless on a 3 channel display. And fwiw bichromic white LEDs have
huge colour balance variation, way outside of whats acceptable for a
display.

The Holy Quran



Please forgive us for any disturbance, but we have an important
subject to address to you regarding FAITH, and we Don’t intend to
overload your email with unnecessary messages…

Quran Means "Recitation"

The word "Quran" means "that which is recited; or that which is
dictated in memory form." As such, it is not a book, nor is it
something that reaches us only in written form.

The documentation in writting about the Quran has been preserved in
museums thoughout the world, including the Topekopi Palace in
Istanbul, Turkey, the museum in Tashkent, Uzbekistan and also in
England. Keep in mind also, the Quran is only considered "Quran" while
it is in the recitation form, not in the written or the book form. The
word for what is written and held in the hand to be read by the eye is
called "mus-haf" (meaning script or that which is written down).

Only One Version - Arabic

There are no different versions of the Quran in the Arabic language,
only different translations and of course, none of these would be
considered to hold the value and authenticity of the original Arabic
Recitation. The Quran is divided up into 30 equal parts, called
"Juz’" (parts) in the Arabic language. These are learned by Muslims
from their very early beginnings as children.

21. If WE had sent down this Qur’an on a mountain, thou wouldst,
certainly, have seen it humbled and rent asunder for fear of ALLAH .
And these are similitudes that WE set forth for mankind that they may
reflect.
22. HE is ALLAH and there is no god beside HIM, the Knower of the
unseen and the seen. HE is the Gracious, the Merciful.
23. HE is ALLAH and there is no god beside HIM, the Sovereign, the
Holy One, the Source of peace, the Bestower of security, the
Protector, the Mighty, the Subduer, the Exalted. Holy is ALLAH, far
above that which they associate with HIM.
24. HE is ALLAH, the creator, the Maker, the Fashioner. HIS are the
most beautiful names. All that is in the heavens and the earth
glorifies HIM, and HE is the Mighty, the Wise.

(Alhashr 21-24)

Which is why, given that they've put these LEDs under at least some kind of
control in order to implement their (claimed) enhanced black reproduction
scheme, that I was questioning whether the scheme maybe allowed for a degree
of user intervention under the guise of "tint" or whatever, and which might
have accounted for why on this particular TV - the only example that I've
seen on and working so far - the flesh tones were so poor compared to Pan
and Sony offerings in the same display stack, showing the same picture. I'm
trying to get a handle on why a company with the products and reputation of
Sammy, are a) using advertising terminology that appears to be questionable
in the context that it appears, and b) producing a set, claiming it to be
the dog's ******** of display technology, which does not appear - to my eye
at least - to be as good as their traditionally CCFL backlit offerings, or
those of other manufacturers.

I saw the latest all singing and dancing LCD HD Pan, just released, in my
friend's shop yesterday. Uses conventional CCFL backlighting. Not as thin as
the Sammy, but getting there. Apart from the usual slight gripes that you
could direct at any LCD panel when examined closely, the picture was quite
stunning, and the colour rendition was as close to 'perfect' as you could
reasonably expect. Certainly, flesh tones *appeared* accurate, but I accept
that is subjective. Anyway, whichever-whatever, more accurate than they
appeared on the LED backlit Sammy ...

The why is pretty clear. Samsung is a whore, like all of the other vendors,
only a little more so than some others. They are interested in market share
and will create whatever hype they think will help them sell sets. The
degree to which it is actually better only has to matter up to the point
that too many people figure it out and it hurts sales. As we get better at
quantifying why the sets look a little weird on certain colors they will
improve the spectrum of the backlighting and improve the color decoding to
compensate. It won't happen if people keep spewing the nonsense that all
you have to do is hit the primary and secondary colorimetry targets to get
perfect color. That is just a starting point, and for some sets that do not
have proper color decoding or gamut, may actually be the wrong compromise.
