OLED???

[ASAAR]

Yes. Mild dyslexia. Bad place for it to happen, though. :-]

You probably need more sleep.

Yes, of the eternal kind.

It is called a color wheel, not a "triangle"--at least it was when I got
my degree in color. White light is a full spectrum.

Pantone Calibration instrument.

I think he is talking the color gamut graph... which is not a wheel, but a
triangle.

Just a suggestion, you need to the loose the attitude and learn to play
nicely with the other children.

 

[Roy L. Fuchs]

Except, LCD displays are not really subtractive color systems. They
have filters to provide primaries, which are then ADDED by the limited
resolution of the human eye (just like the striped color CRTs).

If they were full subtractive color systems with three layers, they
could generate any color at any physical spot on the screen. This could
increase the color resolution.

However, as with the CRT, it doesn't matter, because the color resolution
of the human eye is substantially less than the luminance resolution, so the
effort for increasing color resolution would be essentially wasted.



How about to have a display for portable devices (like cellphones)
that has lower power consumption than backlit displays. Such a device
would not need the high voltage source for the backlight, so would
save some manufacturing cost.

Well I was actually specifically referring to large form factors.

Eventually, it will be the display of choice. The 19 Million pixel
IBM already is in the movie industry.

 

[Paul Hovnanian P.E.]

Try again. Illuminated pixels will always beat backlit filtered
subtractive color mixing schemas.

Always? Then why don't we see more LED based monitors? CRTs aren't bad
for color rendition. We've had years to play around with the phosphors,
and phosphor chemistry is easier to adjust than semiconductor junctions.

Probably the best system, color-wise, is the DLP projection stuff, where
the light source and color filters can be selected separately.

Why do you think there is even a move toward OLED to begin with,
boys?

Not for color rendition.

 

[Roy L. Fuchs]

Aw, don't try to confuse the issue with facts.

Facts?

Three backlit "filtered" light sources ARE subtractive method. The
three together form clear or white, not black.

Opaques are additive color mixing. The three primaries added make
black.

 

[Roy L. Fuchs]

It is called a color wheel, not a "triangle"--at least it was when I got my
degree in color. White light is a full spectrum.

Not in additive mixing.

It is NOT a color wheel. The item I refer to is made by the SMPTE
folks. It is called a CIE Chromaticity chart, and has a triangle like
shape.

You must have been asleep getting your degree when they went over
how to measure color.

 

[Roy L. Fuchs]

People that are as defensive as you usually turn out to be dumbass morons.
You use insults and anger to hide your ignorance.

You're an idiot. You are also guilty of your own bullshit remarks.

 

[Roy L. Fuchs]

For my work I know this: CRT's aren't as sharp or detailed as LCD.

You're an idiot.

 

[Roy L. Fuchs]

As far as practical application--that I use--it is better. I compare my
Viewsonic 19" to my Trinitron CRT. My print match is better and both were
calibrated. The LCD is also sharper.

You're a joke.

Tell us, oh all knowing twit... what are the dot pitch specs on both
devices?

I'll bet the sony tube is a 0.25 or less phosphor pitch.

I'll bet the LCD is a 0.28 or higher.

If it was the defining element back when CRTs were all that were
around, what makes you think that has suddenly changed now?

Sharper indeed... Sure, bub. About as sharp as you are, Oblio.

 

[Roy L. Fuchs]

Why? Ancient history that's why.

You're an idiot. This discussion isn't about what is currently being
marketed to the masses. It is about quality, you retarded sidestep
punk.

CRTs are still king, regardless of what is pushed onto the shelves,
or how bent your fuched in the head logic is.

The ONLY reason CRTs are not being made in today's large form factor
world is that the glass is too hard to make at that span. Otherwise
they would STILL be king, and would STILL be being marketed.

SO the ONLY driving factor here is cost of manufacture, NOT quality,
dipshit.

CRTs are king and would still rule, if one could get a 50" tube
made. One starts running into relativistic problems as well at those
spans, however. That one likely went right over your head as well.

 

[Roy L. Fuchs]

Putting the same image on my trinitron and on the LCD, I will see more
detail in the LCD image. Practical facts.

You're an idiot. Just because you declare that to be what you see,
doesn't make your claim correct, so you cannot call your CRAP "facts",
dumbshit.

 

[Roy L. Fuchs]

Oh and you are right about not knowing what a motion artifact is--on my LCD
I NEVER see them. I watch sports--never see them--action movies--never see
them. Depending on the broadcast I do see when crews aren't using HD
cameras or the really good HD cameras.

More proof that you are too blind to even be in this thread.

You must be trolling.

Additive color adds the primaries {red, green, blue} to make white.

Subtractive color uses {cyan, magenta, yellow} - when all are used
to generate black.

Look it up.

Interesting claim. A bit of google searching found no references to
this 19 million pixel IBM display. Can you provide some pointers or
other information that will allow one to find any more information on
it?

Additive color adds the primaries {red, green, blue} to make white.

Indeed, additive color mixing is used with light sources, you add light of
different colors of light to the dark.

Subtractive color uses {cyan, magenta, yellow} - when all are used
to generate black.

And sbutractive colors are used with ink/paint on white surface, hence you
subtract colors from the white surface.

They made it like two or more years ago. It is not a production
item.

It does 24 Hz at its max res.

What is a backlight?

On a crt, there is no e-beam on a black image. How is black created
on an LCD?

When the light source is white (as with a backlit LCD) then the filters in
front subtract the light and therefore the three primary filters will make
black. Do not confuse this with colour printing.

 

[Meindert Sprang]

When the light source is white (as with a backlit LCD) then the filters in
front subtract the light and therefore the three primary filters will make
black. Do not confuse this with colour printing.

But you should not consider an LCD like this. Otherwise additive colors made
by incansescant lights and R/G/B filters would also be subtractive.

In a backlit LCD, you have a white light source which is regulated from low
to high intensity by the LC and polarizers. After that, each pixel has a
color filter which makes each pixel a light source being either R,G or B.

Additive color mixing is per definition mixing of colored light, emitted
directly from a source before an object reflects the light.

Subtractive color mixing is per definition created by reflected light and
colorants that absorb certain colors.

So per definition, anything that makes colored light by itself, by use of
light sources, is additive mixing.

By dimming the light through the liquid crystal before it hits the color
filters.
