You're going to need to substantiate your statement about 16-bit color, because I think it's wrong. It may have applied to earlier-generation devices but I find it hard to believe OLED HDTVs are coming to market (Samsung invested US $2.1 billion of a new gen 5.5 factory, and this year is investing US $4.8 billion more for a gen 8 factory for HDTVs up to 55") with less than full color depth. In fact, even 4 years ago OLEDs had greater than 100% NTSC color gamut according to this review of a Sony OLED display:

In addition here's a list of some OLED devices on the market now, with many listing 16 million+ (24-bit) color depth.

I already agreed that OLED is the future. It is improving at a rate faster then LCD. It's potential far exceeds that of LCD. However today it is behind in several critical areas. Most importantly sub-pixel density. The best S-AMOLED screen commercially available today have about 1/3 of the sub-pixel density of current IPS displays. This directly results in noticeably less clear text. Manufacturing processes need to improve before this can be addressed.
Go ahead and and prefer AMOLED if you wish. I'll join you in a few years. For now I just want the sharpest text possible.
Some comments about the OLED screen in the Nexus One (which was basically a rushed prototype):
And those comments above are about an INFERIOR OLED screen - imagine what they're saying about the one in the Samsung Galaxy S and other newer phones...
The overview link below shows that the Nexus One is not what you should be comparing when comparing OLEDs to LCDs, unless of course you have an agenda of dissuading people that OLED is the next generation display of choice.

Not much point to the quote since it's talking about outdated OLED and outdated IPS. (nexus one vs 3gs)
Umm. Who's side are you on? Your link is very critical of the PenTile subpixel layout on the Galaxy S and actually ranked the iPhone4 IPS display as better overall.
interesting that the award given to the OLED was not applicable to the LCD screen, since it's not new tech.
I voted No. Because I believe you cannot increase the screen size without increasing the physical phone size and IMO the iPhone 4 is big enough thank you. I am yet to see any phone with a 4" screen that is not bigger then the iPhone and when it's in your pocket you notice it.
It I could have a 4" screen with the exact same dimensions as the iPhone 4 then fine. I would love it, but I also demand it to have a increase in resolution because Apple have made such a hi-res 3.5" screen they would be going backwards if they didn't increase the resolution along with the size.
As for the screen tech, the retina IPS is more then good enough, it can easily hold it's own against amoled, but the screens need to function in all lighting and the retina is better at this, what's the point in a phone you can't use outdoors?
So I will happily have a 4" screen so long as it does not mean sacrificing screen resolution or phone physical size which I believe is what you would have to do.
A better camera is more important to me.

The title of the thread is "Do you want a 4 inch Super AMOLED 960x640 screen with full RGB subpixels in iPhone 5?"
emphasis mine.
Your statement is irrelevant. No one is arguing in favor of an OLED display with a resolution of 800x480. Both the Motorola Atrix and the PSP2 offer up OLED displays with much higher resolutions near identical to retina resolutions, and Sony's OLED's do use full RGB subpixels so it's likely the PSP2 will as well. A Retina display OLED with full RGB subpixels in an upcoming iPhone is certainly possible. That's the possibility being discussed.
And there isn't a sane reason why anyone with a knowledge of display tech should oppose that.
The thread title is irrelevant if such a display can not be producted in time for the iPhone 5. As for now, the thread title advocates an unproven tech (high density full sub pixel OLED). Every high density OLED display available uses PenTile. When I see a Super AMOLED that is subjectively of the same clarity as the current iPhone, I'll change my mind. I'm not going to vote for a tech that in every publicly available product delivers sub-par clarity.
BTW - The Moto Atrix doesn't even use OLED. It's the worst of both; a PenTile RGBW LCD.
I cant find any information about the PSP2 display, other then some speculation that it is also PenTile. The details may not be quite locked in by Sony. I guess we need to wait and see.
I'll say it again; I like OLED. I really do. I'd be shocked if it hasn't surpassed LCD in every way in time for the iPhone 6. I'm simply skeptical that the tech will be able to produce the same level of clarity in time for a launch this summer.

The PSP2 I believe does indeed use Sony's OLED tech and it's resolution is very close to the retina display
No one thought that the technology for a 320+ dpi resolution on a consumer class device was possible either, until Apple unveiled it. Apple can make a 4 inch 960x640 resolution OLED with full RGB subpixels happen.
Apple was just recently evaluated as the richest company in the world, higher than Exxon! They have billions upon billons of dollars to throw into Research and Development, far far more than Sony does. If Sony can pull it off, so can Apple.

Maybe, that's speculation. But since it's a 5" display, it would actually be a far easier display to produce since the DPI will be lower. Most importantly, even this will not be available in time for summer.
That's simply not true. LCD devices had been at that quality for years. Look at the Xperia X1 with it 331 DPI display from 2008. OLED on the other hand is currently at about 1/3 the sub pixel density required to meet the title specs.
Your suggesting that Apple can create a secret process to improve OLED fidelity by 300%? Only Samsumg and Sony are in a position to make such an advance, and they brag to the press about every jump in quality. Sorry, but I don't buy it.

The Xperia X1 had a resolution of 800x480, not 960x640.
And no it's dpi wasn't 330 either, the iPhone 4 was the first consumer class device with a 330 dpi display.
And lastly, the Xperia X1 had a TFT display capable of only 65k colors, comparing it to the displays on modern smartphones is laughable.
Apple leads the pack in R&D in a number of areas. They led the pack in multi touch capactive display tech with the original iPhone. They led the pack with tablet display tech with the iPad. They also manage to make their devices thinner than their compeitors could ever dream of, while managing to squeeze in larger batteries. They absolutely can keep up with and surpass Sony in terms of R&D.
So let Apple's R&D worry about the technicalities. The thread asks a very simple direct question, mischaracterizing the thread to instead be about 800x480 resolution pentile matrix OLED screens is dishonest.

Lower res, but smaller screen (3"). DPI works out to 331.
OK, look at the Droid. 275 DPI IPS. Your still comparing at 20% improvement in LCD to a t 300% improvement in OLED. My point is that nobody thought the RD display was impossible, where as the OLED for right now, just may be.
In my mind, if your going to ask for unavaible tech, your not thinking big enough! I want the iPhone 5 to have a holographic display with 4k resolution
The question isn't that direct if it can't be done.
To rephrase the question:
Look at this tech. While it has terrible clarity issues right now, imagine if it didn't! Would you want that on your next phone?
My answer is:
Show me the new version of the tech. I want to see that it works well and hasn't introduced any other issues before I vote to have it replace an already excellent display

No it doesn't. Your math is wrong. And also comparing a 65k TFT display to the iPhone 4's display is misleading.
And I'm saying that you have absolutely no basis to say that it can't be done, especially considering that Sony has already demoed full RGB subpixel OLED displays. Hell, not just Sony, some random company, UDC, demoed OLED displays with full RGB subpixels with even one more color added beyond just R, G and B. And they did this an year ago.

Besides, Apple has repeatedly done things over and over again that hadn't been done yet, especially when it comes to display technology in consumer devices. The original iPhone's display was like nothing on the market, same with the iPhone 4's display, and the iPad. With the amount of cash that Apple sinks into R&D, it's not just possible, it's very likely that they are working on OLED tech thats ahead of what's already seen on consumer devices.

As I said IPS displays were already in the ballpark with the Moto Droid being at 275. The 20% jump was not revolutionary.

Yes, do you? 800x480 on a 3" screen is not 331 dpi. Do the math yourself or use a dpi calculator. You claimed the Xperia has a higher dpi than the iPhone 4, and that's factually untrue. And more importantly, comparing a 65k TFT display to the iPhone 4's display is laughable.
Just give it up dude. You're wrong. Multiple companies have already demoed AMOLED screens with full RGB subpixels. And given how much money Apple sinks into R&D, and how many times they've led the pack in terms of displays found in consumer devices, it's not by any means unreasonable that Apple has access to that same tech.
Again with the false statements. Even according to Motorola themselves, the Driod has a DPI or 240, not 275, and certainly no where close to the iPhone 4's 329.6 DPI.

This rumor that we're getting a four inch iPhone now is AWESOME.
I would kill for that design. An iPhone 5 with a 4" screen and the same size, and an iPhone Mini with a 3.5" screen and a smaller size than the current phone.
Is it a coincidence that the front page story on macrumors about the 4" screen reused the exact same picture from the opening post of this thread? That seems unlikely.
This!
