Are you yellow?

[pixelthis]

Sharp has announced that in a few months they are introducing a monitor with not just
the three primary colors as pixels(red,blue,green) , but four.
The fourth one will be yellow..
Seem to remember sets used to have red, blue, and yellow, way back when.
Anyway, this will give Sharp TV sets the ability to display over a trillion colors.
Anybody want to buy a slightly used Vizio?

Well sharp has been slipping a bit, so maybe this will help them along, but the days of Aquos envy are over, I think.

I don't understand color defintion very well, and don't know what adding yellow would do specifically. However I do know that you can define yellow in terms of red+green+blue.

Thus on you computer in, say, Paint, you'll notice that pure, bright yellow = Red 255 + Green 255 + Blue 0. In this scheme the maximum colours you can define = 256 ^3 = 16,777,216.

I don't know what "32 bit" color means either, although the maximum values that can be defined in 32 bits = 2^32 = 4,294,967,296, (which is also the maximun number of memory locations that can be directly address by a 32 bit O/S).

you can make any color with a combo of the three primaries.
But you can get more accurate color with four primaries.
Some DLP sets have six color wheels to give a better color palete.
Cant wait to see how this one looks.

OK Pix, yuz have to 'splain dis to moi please.

The yellow is a marketing gimmick as we already cannot perceived the all of the colors coming from a simple RGB setup. Don't waste your money on this, unless you are a chump easily affected marketing crap. The color accuracy is in the processing, not in an extra LED.

Anyone heard of product differentation?

Not a "fanboy" really.
Just had a chance to get this player, more "current" than my old Sony.
The menu isnt as pretty, but is faster, and it has more features.
Its the same half chassis as a lot of stuff from China, so it fits into my gear a
lot better.And the pic and sound are great.
Only improvement over my old player, I can discern HD video and HD film a little easier.
Its just a co-inky dink that it was Sharp that came out with this set, and I thought it was
news-worthy, is all.
Unlike Talky, I am keeping an open mind on the subject.
Actually SHARP is on probabtion with me.
True they pioneered modern LCD, but their early projectors had that notorious
"screen door" effect, which, while long gone, has plagued the LCD screen ever since.
And a friend has fond memories of Sharp, bought a Sharp VCR that literally fell apart
right after the warranty expired, although this was a long time ago.
Anyway I really like their player so far, its fast, has great features, and more importantly, accurate picture and sound, and I can tell what kind of sound I am getting.
I consider them "on probation", this is their last chance with me(I gave Toshiba four
chances before I gave up on them)

What point is it to keep your mind open when you already know (and have confirmed) that adding it really does anything. It will not make it any more accurate than a Kuro's running a 12bit RGB, or not even close to the My Sony Trimaster's 16bit RGB processing. You just don't need it, it is all in how the processing handles the balance between the necessary LED's to get a pure yellow, and a properly calibrated plasma or LCD with the necessary processing can do it just fine.

It is a bleedin gimmick!

Thats your opinion, and thats all it is.
Truth is you havent seen one of these sets, you don't know what the execution will
look like.
Of course, if its a roaring success you will be right up there on the bandwagon.
Or maybe not, after all this isnt 20 year old CRT crap that you so blatantly love.
Truth is you havent seen one of these sets, and you may be right.
Or you could be wrong.
Excuse me if I hold out judgement .

Just so you quit your constant yammering about CRT's, I own a 60" Kuro's, a 65" Cell based LCD, a Sony XBR 10, AND a Sony G90, and a few more display devices. So CRT's are not the only viewing device in my hometheaters.

This was tried before by Sony and Panasonic professional division three years ago (and yes I have seen it before), and it was found to be not needed(I wouldn't say so if I didn't have information that told me as much) because good processing mitigated the need for a yellow LED. Pure yellow (red and green) can be acheived with good processing (as many plasma's and LCD already have), so (I repeat) there is no reason in the world to incorporate it unless you are just trying to differentiate your product from your competition.

Everyone now has a edge lit backlighting system, LED backlighting system, 10 bit processing, Sony has the Trimilous, and now you are adding a yellow LED to the RGB LED as a reason to see 1 trillion colors when the eye cannot see 1 billion colors. The best research we have out there on how many colors our eyes can ascertain is 10 million which is well beyond the 16.7 million you get with 24bit.

If we cannot see billions of color, then why go to a trillion?

If you think about this critically(instead of being a known target for marketing depts) it is not needed, and they will just charge top dollar for another unneeded gimmick.

Well, I guess for the same reason people like audio that goes to 20,000 hz,
even though most cant hear much beyond 12,000 or so.
Be interesting to see what the execution is, is all I am saying.

A speaker that goes to 12k may start rolling off around 8 or 10k. A speaker that goes to 20k should be pretty flat around 12k. I'm just sayin'.

An extra color that doesn't add anything that can't already be done is a waste of money. Just extra things that can go wrong. I'd stick with the K.I.S.S. method.

20khz is the limit of the hearing capabilities in humans. While older men generally have a cutoff at 12khz, there is a whole swath of folks (including women) that can hear right up to the 20khz cutoff. My last hearing test showed I can hear solidly up to 16khz, it was down 6db at 17.5khz.

A system that cutoff at 20khz is still within the capabilities of human hearing. But a trillion colors is so far past what we can see, it is a waste of time trying to reproduce it.

It is nothing more than product differentiation, and in the end does nothing to advance the viewing experience. It will allow the manufactuer to charge more for the product, whether you can see the benefit or not.
