There are very good reasons why Apple has not done OLED for iPhone. Its not like OLED is top secret hard to get tech. Even cheap POS China brands have OLED screens. Its more about quality control.
The short life of Blue OLED pixels is horrible. With quick dimming of Blue OLED your screen will never have color accuracy except for the first few months. The only way to correct this is with monthly calibration with expensive equipment done by experienced image engineers.
Second problem is OLED battery drain from displaying white. Most websites, spreadsheets, apps, and docs use white as a background. That is why OLED phones have much larger batteries.
If OLED can fix these two problems then iPhone may get OLED. But until then I'd rather have a phone with very good black levels (not as good as OLED) but with great color accuracy for the life of the phone.
And those test by Andantech and Displaymate don't mean crap because those are new phones. Lets see them test those OLED phones after 12 months.
You are hard to take. Even in a thread where I have provided photographic proof of an OLED screen with 6 years of daily use, displaying an image with bright and vibrant blue hues, you still spout your baseless absolute garbage troll-vomit about 'quick dimming Blue OLEDs'. You are either trolling or are of low intellect.
I debunked that bigger battery nonsense you parroted from macpluplus.
No, Samsung stopped because they had production issues, not because there are better technologies. The large panel OLEDs are notoriously difficult to make with terrible yields. LG's production process is obviously superior.
I read that Samsung had to license LG's technology and patents for OLED. Probably not cost effective.
The problem with whites in oled is not what color they are but how much energy they consume. White oled consumes more energy than white LCD. Apple's use of oled in Apple Watch can only confirm that: All Apple Watch interface is white on black background.
This is why iPhone SE easily beats Galaxy S7 in battery life. Thirteen hours compared to only ten hours.
Actually, the 4" vs 5.5" display and the 640 x 1136 pixels vs 1440 x 2560 pixels is far more likely to be the source of any difference. And you are just wrong about the batter life anyway. GSM Arena which have a standardised battery testing protocol rate the iPhone SE at 73hrs, the Samsung S7 at 80 hrs and the Samsung S7 Edge at 98 hrs - try again.
Burn-in is always an issue in those colored molecules excited to emit light. LCD molecules are colored but not excited. Light is provided via backlighting. But when you continuously excite a molecule to emit light, some workout will happen and the substrate will deteriorate as a result of continuous excitement. So, burn-in. All LEDs and light bulbs have a finite life, which is shorter if you use it continuously.
Yes, but TV is the least likeliest scenario for burn-in to happen especially in an enthusiast market that Plasma played in. Where the users would be the most likely to be knowledgeable, yes, a non-issue.
But as you took it to the logical conclusion, EVERY display requires regular calibration due to back-light degradation over time as well
The display getting dimmer and the display shifting colors are not the same thing. If one day backlight LEDs don't fire up then you just replace the screen. The reason for oled is not that, the reason to remove one plane is to make it cheaper. Cheap tech...
So people should be knowledgeable as to not play video games continuously for two hours but that didn't happen and plasma died.
That article says nothing about LGs panels' oled resolution... What about 5K? Apple has such an iMac...
Unlike backlighting LEDs, those are tiny tiny tiny pixel size diodes which get submitted to electricity, ie. excited to emit light. As the pixel size gets smaller and smaller it is obvious that the production defects will increase as well as deterioration speed. A 5K oled iMac is beyond even your imagination...

The hours I quoted is WSJ real life test not this theoretical testing.
Why LCD may get dimmer (the backlight) that just means the image won't be as bright. When OLED blue pixels get dimmer the color is thrown off completely.
Here is an example of an 18 month old phone vs a lightly used OLED phone. Exact same model.
This test was done in Jan 2015, so I don't want to hear any excuses that new OLED is much better.
having blue pixels dim before red and green wrecks havoc on OLED screens.
I have seen that page. There are a couple of problems I have with that. Without before/after photos it isn't really possible to tell if that is actual panel aging or sample variation. Given the two phones were made for different markets and are internally different and are running different OS versions, I'm not sure we can even say the panels would even have the same part number or that the beta OS one of them was running might be causing an issue.
My 15" RMBP has a Samsung made LCD panel. Some panels in exactly the same model bought at exactly the same time had LG panels. Most of those developed serious issues and I suspect most such machines had to be replaced by Apple. There was quite a stink about it at the time. So it is clear that devices do not always have the same parts in them even if they are the same model and made in the same time frame.
But there is another possibility the author of that piece doesn't even mention. These images are of my Nokia 720, which has an LCD. The camera was set to daylight colour balance and the exposure parameters were locked between shots:
Looks a bit like the variation the author of that piece has noted and is getting blog clicks from. Has the LCD aged between photos - of course not. In Windows Phone OS you can adjust and calibrate the colour profile, and that's what you get if you go from warm to cool and adjust the colour temperature of the display:
Heres a picture of a recent Samsung OLED with burn in. This is white screen but notice how there is a ghost of the tool bar.
This type of crap is unacceptable for an iPhone.
Could you please give me the link for the page that image came from. I read somewhere someone playing some stupid game managed to screen burn his S6 by leaving it on the same screen for 3 months. As I said elsewhere, if Apple go AMOLED and they think it might be an issue, expect to find a screen saver in the accompanying version of iOS.
It isn't a problem, actually, because everything that isn't white, especially black, consumes less energy so the overall energy consumption works out to be less in total. You seem to have a fixed notion that iOS can only always have a white background theme. Has it occurred to you that Apple could provide the option of a dark background? I'm sure if Microsoft can manage it with Windows Phone OS, that Apple could too.
Again showing your complete ignorance on readability and usability. Yes it's easy to reverse the color schemes, but it's HARDER ON THE EYES. This has been documented way back since the 80's (when monitors were green on black) through numerous studies on the readability of text.
There's a very simple reason why we use black text on a white (or off-white) background. It's EASIER TO READ. Although there are certain circumstances where white text on a black background is better, these cases are in the minority.
You'd have to be a complete idiot to switch to a color scheme that's less readable and harder on your eyes just to save a bit of battery power.
You don't read the OS. I find the dark theme easier on the eyes as I often use the phone in dim lighting. It's an LCD so I don't have it set that way to save power. In browsers and such you get black text on a white background, as you would expect. I have a nice e-book reading app where the page is slightly beige, which is a lot easier on the eyes than stark white. The greater energy usage OLED has displaying white is more than compensated for by the lower energy use involved in displaying everything that isn't white.
Hopefully there will be wireless charging... I'd think this could be one of major reasons for ditching metal back.
I know many (who don't use wireless charging) are downplaying this feature, but man is it convenient. I keep one charging pad on my nightstand where I normally keep phone over night, it is habit and I don't even think of it anymore - I just put phone there before going to bed, and it is fully charged in the morning. It is convenient to a degree that I don't even think of my phone's battery life any more - it almost feels like it goes on forever and does not need to be recharged.

Of course they won't ditch metal back even for wireless charging. That would reduce the color options to only black and white and would be a stupid business decision in every aspect. It took a few years to provide these color options and they cannot step back.
There is nothing to discuss, it's true and common knowledge. Open a full screen black image on your iPhone, iPad or iMac and turn the lights off. In complete dark you will see the screen, and that's because it's not black but grey. Do the same on the Apple Watch and you can't see the display. Even if part of it contains text you won't see the edges. OLED blacks are real blacks.
There is no "real black" in the nature, at least in the close one. Real black is the ultimate lack of energy, which is only possible in the underground, several kilometers underwater and alike. So what will you represent with the "real black" since there is practically no such object or scene in our daily life? Even the darkest night sky is "gray". So that black fetishism is just a marketing gimmick. Avoiding 100% black and 100% white is the basic rule of graphic arts so don't try to present a defect as a feature...
You cannot even shoot real black, there will be always a bunch of stray photons that will come up to ruin your screen experiment. So discussing how to display something you cannot shoot makes no sense...
Oh my GOD. Can you be more ridiculous and play more on words? It's black, deep black, it emits no color or light visible with the naked eye.
And actually what you are saying is utterly false. The black on an OLED screen is as black as the black in the deepest parts of the Earth. If you could go there and turn an OLED display, it will all remain BLACK.
And of course what you are saying is also false in that if you go underwater or underground there are still tons of photons flying everywhere, especially infrared. So if you want to go with that definition of black, yes, perfect black doesn't exist. The closest body that emits no radiation is a black hole, and even there x-ray is emitted all the time.
But we are among reasonable people, and I thought that when talking about BLACK it would be clear that we would be talking about perfect pitch black for human eyes. I guess I was wrong thinking you would be a reasonable person. Blocked.
All Glass. All black. Rounded edges. Seamless OLED display. A rounded glass dark monolith. Subscreen fingerprint sensor. Subscreen speaker and camera.
One can dream.
The bolded part is obviously where Apple (or Sir Jony) intends to go but I have to question the italic part. Where in the screen will you put finger print sensor that will be more natural than now? And what'll happen when software fails and you need to do a hard reset? Also, how to take a screenshot?
I just don't see a more benefit for Home-button-less iPhone, apart from aesthetic, and I hope Apple won't ditch a very important feature (physical button) just for the sake of aesthetic. I hope Apple is smarter than that. ..unless of course Apple has some smart tricks in mind...
I agree, removing the home button would be the hardest part. And I also agree that we still need to ask : do we need to remove it? But a part of me thinks that we are going in that direction. I don't know how exactly, but I have some ideas, some which a lot of people wouldn't like.
I believe that for example what Android does with the three buttons is just perfect. Sure it's not as simple as a single one, but is one button that does 4 or 5 different things better than three buttons? I don't think so.
iOS 9 introduced back buttons on the top of the screen... the top! Why not put them in the lower left part of the screen ? Put the home button in the middle with the fingerprint sensor right under the screen. Put the multitasking button on the right. People would say iOS has copied Android but who cares? It's the best way to do it, I'm convinced of it.
About the reset... keep the power button longer than usual.

Please explain how having one botton to go back on the lower left side is a worse experience than having it on the upper left side far from the thumb, small, and hiding the network icons.
Please explain how having to double click one button is better than pressing a single one.
Please show how much of an expert on user experience you are.

The Samsung S6 and 7 have glass backs. That has not limited colour choice.

As the pixel size gets smaller and smaller it is obvious that the production defects will increase as well as deterioration speed. A 5K oled iMac is beyond even your imagination...
The Samsung S7 display is 1440 x 2560 pixels (~534 ppi pixel density). The 27" 5K iMac is 2880 x 5120 with a ppi of 218.
That means that if Samsung could scale the S7 panel to iMac 27 dimensions, it would have 7055 x 12542 pixels. Sharp's 8K TV is 4,320 x 7,680 pixels.
So no, a 5K OLED panel is not beyond my imagination, only your's.

Because the way you hold the phone the lower left side is touched inadvertently all the time.

What are you talking about? How do YOU hold your phone that you touch the lower left side all the time. Or even the lower right side for that matter?
