I think all the best of current flagships have screens that look pretty good. I don't care that much about the color and viewing angles differences, unless they are way off. I've never had an issue having had phones with both AMOLED and IPS.

But I do like that AMOLED allows the phone to leave a few pixels always on to display a clock and things like that. I miss that feature from my old Nokia N series smartphones, where you don't have to wake the phone or anything to see the time. And it sounds like this is being used in some cool ways for notifications now too. So that feature appeals to me.

For what it's worth, my Nexus One went for years without burn-in. That's not just an AMOLED screen, but an old technology AMOLED screen. I believe that burn-in happens, but I wonder if it's only for the heavist phone users (I'm speculating, I honestly don't know).

As far as sunlight legibility goes, I know that in general IPS is supposed to be better, but Nokia has "ClearBlack" AMOLED screen that they used in the Nokia 808 that just eclipsed every other screen in this regard. Even though it's now a two year old phone with a defunct operating system, it remains well at the top of the chart in GSMArena's test of sunlight contrast ratio. Not just a little bit better, but way better than even the best of other displays (like in the Note 4 and the iPhone 5). I've always wondered, what is it that's so great about this display and why has Nokia never used it again?

(Found this explanation of the Nokia ClearBlack display: http://www.phonearena.com/news/Here-is-how-Nokias-ClearBlack-AMOLED-display-technology-works_id26552 Makes a lot of sense, but still doesn't explain why neither Nokia, nor anyone else, has achieved as good results with any other display in any other phone.)
[Nexus 6  General] msal:
That's rather interesting. I'm not tossing aside your experiences, but I've had a completely different experience.

I guess it might vary from user to user. I'm a "heavy" phone user; I use my phone for several hours a day and I'm not sure anyone who doesn't. I don't know what defines a light user though, lol. I had a rather overwhelming amount of burn-ins on multiple displays. Granted, that was on phones released 2-3 years ago. I'm sure AMOLED technology has advanced since then, but burn-ins are a legit issue that will always be present on AMOLED because of the way they work.

I've been doing some browsing on other forums and I've seen countless threads where people have gotten burn-ins with some of the best phones of 2013 such as the SgS4 and Moto X. Hell, I went to a local carrier store and every AMOLED display had SEVERE burn-in. Of course, those are display phones but that's pretty troubling. If I had to speculate, I would assume that in 1.5-2 years, one would notice a considerable amount of burn-in.

Then again, I'm dead-set on the Nexus 6 because I think it's the best phone available atm. Hopefully Motorola/Google's warranty covers burn-ins.
[Nexus 6  General] Baldilocks:
I would have preferred IPS. The Nexus 5 has one of the better displays I have ever used and I would have liked to continue that with the Nexus 6.

I have used and liked AMOLED screens as well. My only problem with AMOLED screens has been banding issues and white or black lines disappearing when you scroll.
[Nexus 6  General] skibadee:
My note 3 has bad burn in. Google maps navigation bars can be seen easily. Only had this one since April. I'm going to try getting it fixed on warranty before I sell it for my next upgrade.
[Nexus 6  General] Schoat333:
In a phone, I prefer OLED. Its just a better technology for a mobile touch screen device. It allows more flexibility than an IPS.
[Nexus 6  General] shadowcore:
IPS LCD with properly calibrated screen and colors.

OLED screens have less pixels, less detail, burn in, produce oversatured colors(On top of OEM badly calibratiing them), consume more battery in white screens(if you hadnt noticed, most websites have the white color or most PDF,djvu etc- documents have a white backgound) and to top it all off, they break more often.

All this for "Contrast".

Nope. IPS LCD is superior. But then, thats what the LG Nexus 5 is for. Maybe google will relaease an updated nexus 5 2015.

But anyway, probably everyone changes their smartphone every year so, burn in, which is the biggest problem with OLED, dont happen as often.

There are other type of panels based on IPS, such as MVA, PLS, and so on, but you never hear about them in smartphones, only in IPS monitors or TVs.

The major problem with IPS displays is when the OEM screws up, tampers with the gamma, and produces a very low contrast or there is light bleeding out of the edges. So all the handicaps for IPS displays are OEM mistakes.
[Nexus 6  General] Semseddin:
i've used droid razr maxx for 3 years and i am a heavy user. Its oled display never had burn in issues. Amoled all the way, true blacks and vivid colors, none to minor gap between digitizer which provide a realistic screen.
[Nexus 6  General] EniGmA1987:
Same here. Im not sure on the cause but I think it has to do with brightness. Most people I know are pretty much blind (to me at least) and say they can hardly even see my screen. To me it is plenty comfortable brightness and not dim at all. I look at their phone and they run brightness at pretty much 100% at all times, and have terrible burn in on their AMOLED phones. So I suspect they simply have brightness so high all the time that it causes burn in.
[Nexus 6  General] Schoat333:
Yes, brightness can be a factor.

The compounds used in the OLED degrade faster with heat. So the hotter the phone gets, the more chance of the burn in effect happening.
[Nexus 6  General] darkchazz:
There isn't a need for 2k on an LCD panel because you wont notice a difference in sharpness between that and a 1080p LCD.

Notice how LG uses a software sharpness filter on the G3 to give you the illusion of a difference.

On the other hand, AMOLED with its horrible Pentile subpixel arrangement needs ALL the subpixels in can get to match the sharpness of an LCD panel.

I think Google went wrong by following the numbers marketing hype (MOAR resolution is better!).

And now Lollipop comes with bright and colorful UI and many white menus, which means the AMOLED display will consume more battery.
[Nexus 6  General] neyenlives:
Correct me if I'm wrong but the benefit of an AMOLED panel is it has no back light. So side by side, everything else equal, an LCD by design will be burning more power to make a half inch circle white and leaving the rest black(by masking the light behind the black part), vs. the AMOLED only burning enough power to light just the white area and not using power on the rest of the screen..... Hence why you get blacker blacks on an AMOLED display.
[Nexus 6  General] EniGmA1987:
True, however OLED tech requires more power for its brightness so it is offset somewhat.
[Nexus 6  General] neyenlives:
Yeah but without numbers I can't draw any conclusion. If an AMOLED screen takes even double the power per square inch of screen lit white..... It's still going to be more efficient lighting a half inch circle white than lighting the entire screen and wasting all that power to mask out all the remaining screen area.... and I seriously doubt it's a factor of 2 in terms of power difference.
[Nexus 6  General] cb474:
I guess a heavy user would have to be defined by the amount of screen on time in a day. My phone probably really only has about an hour of screen on time per day. Mostly I'm on a computer. But I can imagine some people spend hours surfing the web, playing games, etc. So over a the course of a year they could easily have the sceen on for the equivalent of four or five years of use by another person. That would be true, for example, for a 1 hour a day screen users vs a 4 or 5 hour a day screen user. So one can see how a year of regular use could really be two quite different things.

I suppose it should not be surprising that there are a lot of threads on XDA about burn-in. People tend to talk more about problems than not problems (it's hard to imagine countless threads about how people don't have burn-in). On top of that, XDA users could well on average be much heavier phone users than the general smartphone owning populous. So it's probably hard to conclude too much from the presence of these threads.

I assume that if burn-in was something that was extremely common and happend very quickly to most phones, there would not still be so many phones with AMOLED screens, when there's a prefectly good alternative.

I think there are AMOLED screens that have proper color calibration. I don't know that they are by defintion over-saturated.

And overall I do think that AMOLED screens are more power efficient (though not in every use case scenario), so that is a very tangible benefit. Also I think AMOLED screens are thinner, another potential benefit (though obviously the Nexus 6 is not the thinnest phone).

That aside, how do AMOLED screens have less pixels? Because of pentile?
[Nexus 6  General] neyenlives:
Maybe people could stop using their phones while driving, reduce burn and help save lives too. It's insane these days..... Stop at any red light and every freaking body is looking at their phone.... Light turns green.... Every freaking body has a several second delay to start moving between each other....because they are on their phones..... Nobody uses turn signals anymore.... Because one hand on wheel and one hand on phone......

It's getting out of control. I watched a lady completely total out her car the other day. She was on her phone. Semi stopped in front of her, we were in a construction zone, wasn't his fault..... Traffic just stopped bumper to bumper..... and she just absolutely plowed into his rear-end......
[Nexus 6  General] Droid2drummer:
Used to hate amoled only because pentile. But they've finally gotten away from it. So I think its better for deeper contrast. Thats my opinion.

To display a full white image at maximum brightness, the iPhone 6+'s display consumes 1.53W and the GNote 4's display consumes 1.8W but displaying images or videos, the Note 4's display uses only 0.85W when the iPhone 6+ still consumes 1.53W.
[Nexus 6  General] cb474:
Yeah, I totally agree with you on this. Especially the delay at every green light. I never used to use my horn, ever. Now it's a daily phenomenon. For a while, I also thought I was suddenly seeing drunk drivers on the freeway all the time. Then I realized it's people texting or doing whatever with their phones and not looking at the road.

It amazes me too how there is apparently zero enforcement of the laws against this behavior. I even see cops on the phone in their cars all the time and I really don't believe it's official police business.
[Nexus 6  General] WibblyW:
Well for all but GPS/navigation I agree. That use model should be horrid for AMOLED in the summer months - max brightness, high temp, and some static screen elements....

But... I asked Motorola UK, & they said if this [screen burn] happens then the device will be sent to their repair centre so it can be checked and if it is determined that the screen burned itself or any other fault that does not include physical damage, liquid damage or unauthorised repair the it will be covered by the warranty. Obviously this provides some degree of reassurance for the first year of ownership (in the UK) anyway...
[Nexus 6  General] neyenlives:
Used mine quite frequently in just that way in a windshield mount and never had an issue. For hours on end long trips too.
[Nexus 6  General] shadowcore:
Yes, calibration is a big issue for those that can see it. All phones, be it OLED or IPS LCD are horribly calibrated. OEMS deliberately mess around to achieve punchy colors.

As for OLED, yes they produce oversatured colors by design.

Here is why, check this wikipedia page:

http://en.wikipedia.org/wiki/OLED#Disadvantages

http://en.wikipedia.org/wiki/Comparison_of_CRT,_LCD,_Plasma,_and_OLED

A good read on this matter.

And yes, I meant pentile OLEDs, which have less SUBpixels.

The count may be the same, but less subpixels means less detail. However, given that we are entering "QHD" territory, that probably wont matter.
[Nexus 6  General] darkchazz:
http://www.anandtech.com/show/8687/the-nexus-6-review/3

As suspected. The AMOLED display used in the N6 is the same old display revision by samsung that is used in the 2014 moto x.

The less efficient display combined with lollipop's bright UI elements also equals less battery life.

In my opinion this is a downgrade from the excellent IPS LCD used in the Nexus 5.

And concerning sharpness, the QHD AMOLED actually has less overall subpixels than the 1080p IPS due to the PenTile subpixel arrangement.
[Nexus 6  General] cgulliver:
IPS definitely. Aside from the accuracy issues with the N6 display, moto comprised big time on brightness... kind of a head scratcher. Assuming the display is manufactured by Samsung it is inferior to the superamo tech in their flagships. One would think the n6 display would not have been nerfed to this level.
[Nexus 6  General] Nitemare3219:
That's not confirmed it's the same. They said there are similarities. Also, there is still an increase in subpixels regardless of it being PenTile. It's not nearly as much as if it were RGB, but it is still about a 20% increase.

[Nexus 6  General] RamOdin:
After using the G2 for a year, and getting the G3 (returned because of battery life downgrade), I absolutely LOVE IPS displays. I really don't like the misrepresentation of color Samsung AMOLEDs give.. My 2 highest priorities on a phone are battery, then screen.

It's all preference, but 1080P IPS is my ideal screen. I don't care for 4k resolution, not noticeable for most and draws more power. I'm going to test the N6 and return it if I don't like the screen or battery power - plenty of G2 roms out there for L soon.

Plus, I had a Moto X for a bit and I tend to browse a lot, so the screen will usually be full of white - IPS already has the whole screen backlit, so it doesn't affect battery but AMOLED requires far more juice to constantly power white.

If I don't like the N6, I'll wait for LGs next edition in the G series.
[Nexus 6  General] szucsgf:
No phone in the world has a 4k screen. Why are you comparing 1080p to 4k? The N6 screen is 2.5k, 1080p is 2k.
[Nexus 6  General] RamOdin:
Ok, huge mistake on my part...how about replacing 4k for 2.5k in my post then reread.

My point is, 1080p is the highest resolution I need. I don't care for PPI of 500-600 range.
[Nexus 6  General] dazed1:
PPI on Amoled are VERY important, much more then on IPS, even 4K Amoleds won't have perfect sharpness.
[Nexus 6  General] noobdeagle:
i still find it strange they went with AMOLED considering how much white is actually in Lolipop, if it was a dark theme (or if there was that option) we could get much better battery life
[Nexus 6  General] dcrandon:
AMOLED for the better blacks, but I don't really care, as long as it's calibrated properly. Unfortunately, for the few reviewers who've actually objectively measured the screen, it's color accuracy is relatively poor. Disapointing in that it doesn't have to be that way. It doesn't cost more to calibrate the display properly, you just have to do it, and also disappointing considering the N4 display was very good in this respect.
[Nexus 6  General] Dr Faustus:
You can invert the colours making all the white areas dark. Plus there are already a few people talking about making a dark theme for Stock 5.0 just for this reason.

Its a NEXUS device, the concept why a lot of us here enjoy Nexus devices is because of the Open Development that can be done to improve them from their initial release. Almost any flagship device out there has a Pure AOSP port available but Nexus devices have the most development going for them on every level because of how open the system is. Colour Calibration is small peanuts compared to what we can develop on the Nexus 6. I am still expecting someone to get a true Inspired from internal testing Multi-Screen support for the N6/5.0 and more.

Also when you are talking about the N4, I hope to god you mean the Note 4. Because if you are talking about the Nexus 4, that was by far the worst screen we had in a Nexus with the factory issues it had.
[Nexus 6  General] dcrandon:
Whoops!! Sorry meant N5!
[Nexus 6  General] Evo_Shift:
I'm glad it has amoled because there are apps like led blinker or noled that work with amoled screens for notifications since they decided not to put a notification light on this.
[Nexus 6  General] doitright:
Technically, you are correct.

But I think it is important to acknowledge how RGBG does actually cheat on resolution. If you consider the single color components individually, then you can actually see that an LCD is actually a more dense device, per individual rows.

I.e., for both the R and B components, you are looking at a resolution of just 2560x720 = 1,843,200 pixels. Compared to an LCD 1920x1080 = 2,073,600, which is completely honest in its claims .

---------- Post added at 06:38 PM ---------- Previous post was at 06:27 PM ----------

The problem with these reviews, is that they are using samsung devices as a baseline for "correctness". Samsung devices are responsible for how most objective views on amoled describe them as being massively oversaturated with POOR color accuracy. Based on the specific complaints from samsung lovers, the only conclusion you can really come to is that the N6 may be the most correct amoled anybody has ever seen.

---------- Post added at 06:45 PM ---------- Previous post was at 06:38 PM ----------

It is still not actually confirmed that N6 lacks an LED. It is only confirmed that there is nothing that is MAKING USE of an LED. The N9 *has* an LED, which is not used. Similarly, MotoX has an LED, which is not used.

In any event, you should be reading the thread's question as "AMOLED" or "LCD WITH A NOTIFICATION LED".

It is also worth considering that there is really nothing about the new on-screen notification system that makes it especially amazing with an amoled vs LCD. These notifications don't stay on continually -- they just blink on briefly and then fade off until some event that causes it to briefly show again (bump or timer).
[Nexus 6  General] pedxing:
Have you tried this? I have and it looks horrible.

A Dark theme ROM would be the only way to go.
[Nexus 6  General] letom:
Almost certainly does cost more to calibrate it more.
[Nexus 6  General] ECrispy:
Latest gen Samsung AMOLED panels are the best displays made with zero weaknesses, period. Multiple independent tests have said so.

There is nothing an IPS panel does better. Just look at the Note 4 panel - best display ever made. Of course the Nexus panel is poor - its probably 2 generations old.
[Nexus 6  General] jbdan:
They do have a weakness. They burn-in. All amoled do. At a much higher degree than any LCD. The note 4 at my local store has horrible screen burn I was actually surprised to see how bad it was. Of course this is the worst case scenario where an employee leaves a pop up on screen for days at a retina searing brightness. I'm not disputing the fact that you believe they are the best. I believe you.
[Nexus 6  General] jtwlbz:
Def g3 like LCD period.
[Nexus 6  General] dcrandon:
Umm...no, not really. I said that I was looking at objective tests that measure the color gamut produced, as well as CRI accuracy. It has nothing to do with other phones. Here's a quote from one of the reviews:

To take a look at the characteristics of the Nexus 6's display we turn to SpectraCal's CalMAN 5 software and an X-Rite i1 Pro 2 spectrophotometer for accurate measurements of the display's color. As always, we target the sRGB gamut which is currently the standard for photos on the web and video content.

In our saturation sweep test, the Nexus 6 performs rather poorly. Unlike Samsung's phones which have several display modes with one of them targeting sRGB, the Nexus 6 has only one display setting and it significantly overshoots the sRGB gamut. This does a good job at creating showroom appeal but is not helpful in accurately displaying the color in photos and videos. This is especially disappointing because the Nexus 5 was well calibrated to sRGB and performed much better in this test.

The poor performance in the saturation sweep translates to equally poor performance on the ColorChecker test. The expanded gamut and saturation compression makes it effectively impossible for this display to render any sRGB content accurately. The greyscale performance helps to bring down the overall average, but the large errors with color mixtures prevent any sort of accurate image rendition.

I was highly disappointed by these results. Like I said earlier, we've seen great improvements in the quality of AMOLED displays as of late, and Google took color calibration very seriously with the Nexus 5. The Nexus 6 shows significant regression in color accuracy from the Nexus 5, and the maximum brightness is much lower. It should also be noted that despite its higher resolution, its larger size means that compared to the Nexus 5 the pixel density only increases 12% from 441 PPI to 493 PPI. The use of a PenTile RGBG subpixel layout also means that there is actually an overall decrease in subpixel density.

NoLED has always worked fine on all the LCD and OMOLED phones I've used it on. I can program it to disappear, or stay on forever.

---------- Post added at 05:11 PM ---------- Previous post was at 05:09 PM ----------

How? You mean the extra few labor hours while a programmer measures the output and adjusts the software?
[Nexus 6  General] ECrispy:
I think the burn in is not an issue except for the extreme case you mentioned. The pros are many - infinite blacks, better color accuracy and colors, less power, selective turn on for ambient display. In normal or even extreme use (like playing a movie with overlay for 3hrs) you are not going to get burn in.
[Nexus 6  General] jerrylzy:
Unfortunately Nexus 6 has a poorly performed AMOLED, which results in much worse brightness, color accuracy and battery life compared to Note 4. The display and batterfy life manage to force me to cancel my order.
[Nexus 6  General] alex9898:
IMO, the first problem is that N6 seems to use the same AMOLED Generation that the Note 3. That's not good at all because a 1080p screen of this generation consume way more power than an actual 1440p AMOLED like the Note 4.

The consumption on the N6 screen must be very high.
