Film is a whole nother business. You've got a lot less control over
its 'colour settings' than you have with a display screen, and ditto
re optical linearity. The issues with an LCD screen are quite
different.

well in the sense that they all use combinations of RGB (or CYMK) to
produce a 'full colour spectrum'and none succeed perfectly for all
applications, they are considerably identical, actually.

No, they aren't.

Very basically, you have to understand that:

A printed image is sending reflected light to your eye. It can only reflect
some portion of the spectrum of light it has absorbed.

A screen is is sending transmitted light to your eye, which has no
reflective element to speak of.

Put even more simply, a printed image varies dramatically under different
lighting conditions, unlike a screen.

They could hardly be less identical and the analogy with different brands of
film is not applicable at all.

Color transparencies which are used in pro film applications say your
are a liar.

The term printing was highjacked by photography and film - doesn't mean
the same as the original use. Which was transferring dyes from an
impression to paper, etc.

The LCD only filters light from the backlight. If you don't have a full
spectrum white in the first place the you can't expect decent colour.
White LEDs aren't quite there yet are they?

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.

One day we will be like the aliens in the classic Cadburys Smash adverts -

But at least I could understand how it worked (a bit)

If they ever resolve the legal battles over SED technology, we'll be firing
electrons at phosphors again (although not steering them with copper) and at
last, we will be able to return to pictures as good as CRTs produced ...

I find it hard to believe that anyone could think the same controls
were available to them with a paper/transparency process as with a
computer monitor. I cant think of any possible motivation to prove
whats quite obvious to anyone's that done photographic printing.

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.

In a very broad sense, the last thing you want is a "full-spectrum" light.
The standard primaries are diluted with too much white as it is.

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.

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 bollocks 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 standard primaries are diluted with too much white as it is.

I guess it comes down to definitions and how 'full spectrum' is perceived.
Rightly or wrongly, I tend to think of it as a spectrum which contains the
same component colours in the same ratios, as natural daylight, but I guess
even that varies depending on filtering effects of cloud cover and haze and
so on. Even so, I'm sure that there must be some definition of 'average
spectrum daylight', and I would expect that any display technology would aim
to reproduce any colour in as closely exact a way as it would appear if
viewed directly under daylight. I'm sure that the LCD 'primary' filters are
probably not linear in their transmission characteristics, but probably
close enough that you could use a backlight which contained a similar
spectrum to daylight, and filters 'tuned' to the RG and B humps. All pure
guesswork of course, as it's not my field ...

That's a reasonable definition for a video display, but it's not sufficient

TBH I think this is overplaying the significant of daylight. Almost
any monitor is adjustable to suit preferences of anything from 5000K
to 10,000K, and some go lower. None manke any attempt to copy the
colour spectrum of daylight, they merely include the same colour temp
as daylight as one of the options. None of the major display types
have any ability to copy a daylight spectrum, as they're only RGB
displays.

I think you've missed the difference between recreating the original color
(or the illusion of same), and producing a photographically useful
illuminant. These are different.

But take account of the fact that we're talking domestic television sets
here, not computer monitors. For the most part, TV sets do not display the
same type of content as a computer monitor, and do not include user
accessible colour temperature presets or adjustments, which is why I made
the point earlier that in general, LCD TVs are set correctly 'out of the
box'.

As far as overplaying the significance of daylight goes, I'm not sure that I
follow what you mean by that. If I look at my garden, and anything or
anybody in it, the illumination source will be daylight, and the colours
perceived will be directly influenced by that. If I then reproduce that
image on any kind of artificial display, and use a different reference for
the white, then no other colour will be correct either, which was ever the
case when CRTs were set up to give whites which were either too warm or too
cold, even by a fraction. Maybe we're talking at cross purposes here, or I'm
not understanding something properly, but it seems to me that the colour
temperature and CRI of the backlighting on an LCD TV, would be crucially
important to correct reproduction of colours.

All I know is, is that the flesh tones were poor on the example that I saw,
compared to other LCD TVs which were showing the same picture. The
fundamental difference between those sets and the Sammy, was the CCFL vs LED
backlighting, so it seems reasonable to draw from that, the inference that
the backlighting scheme may well be the cause, no ?

But take account of the fact that we're talking domestic television sets
here, not computer monitors. For the most part, TV sets do not display the
same type of content as a computer monitor, and do not include user
accessible colour temperature presets or adjustments, which is why I made
the point earlier that in general, LCD TVs are set correctly 'out of the
box'.

Every lcd TV I have seen has colour temp adjustments.
