IPS display - Nexus 7 Q&A, Help & Troubleshooting

is it good? I'm only used to OLED.

The IPS display on the Nexus 7 looks good from what I've seen. IPS is known for decent viewing angles.

it depends on the OLED screen you're comparing it to.
the galaxy s2 has super amoled plus, which has a full rgb subpixel matrix, but only a resolution of 800x480. the full rgb subpixel matrix makes everything look clearer and sharper.
the galaxy nexus, galaxy note, and galaxy s3 use a pentile subpixel matrix. its something like rgbg, which makes the display look greenish. its not as sharp as a full rgb matrix, and the colours arent as vivid due to the lack of subpixels (ends up being around 66% less subpixels).
however, the main advantage of the oled displays is that their pixels can be turned off. this means that in movies and games, you have a 'true' black, whereas in led backlit LCD displays (unless it has full led backlight with local dimming) blacks will always seem greyish. oled displays also tend to oversaturate the colours. the other advantage is that since black means the led/pixel is turned off, it means that using a black wallpaper on oled displays will reduce power consumption and improve battery life.
the nexus 7 uses an IPS panel. the general idea is that all the pixels are aligned/parallel, which leads to the image looking sharper compared to TFT and TN panels. the nexus 7 also has a full RGB subpixel matrix which makes it much sharper, and in combination with the IPS setup, it leads to more accurate colour representation. however, as it is not an oled display and it does not have local dimming with a full led backlight (having such a setup would make the device much thicker), it is unable to render 'true' black and as a result, blacks end up looking a bit grey.
cant really say much about which one is better as it is a personal preference thing. some like the oversaturated colours of OLED as it seems more vivid, whereas others prefer the accuracy of IPS panels and sharpness.
at the moment, i own a galaxy note with a pentile amoled display, and i use a 37inch Panasonic TV for my PC display, which uses an IPS panel. i'd say both are pretty good in their own way, but i prefer the IPS panel simply because of the full set of subpixels and colour accuracy.

Waiting to see how hard I rage about the non-black backgrounds.
anandtech measured nexus 7 black at 0.37 nits, whatever that means.

as souai said, it really depends.
generally OLEDs have much better colors and look better, IPS is much better in sunlight though because it's brighter and has insanely good viewing angles up to 178 degrees.
I have a first gen asus transformer which uses and IPS screen and though it's not as impressive color/quality wise as the Galaxy S III and even my Galaxy Nexus (sometimes) it's still excellent and i've never been bothered by it.
and given the fact that the N7 has such a high pixel density it should look great, and the reviews have backed this up.

This isn't apples to apples here but comparing the gnex to the one x I say I definitely prefer the IPS display. Now this is the best version possible probably of its type but I'm happy for the n7 to get an IPS screen. Almost all reviews have talked about how nice it is, only complaint being a little warm and a little dim compared to some other IPS displays. I like my oled screen but since good IPS high res screens have come out, they seem to be superior to oled at the moment. Oled uses up lots of battery in anything other than very black biased setups. IPS has that slight gray to the black but most people are used to their computer monitors and TVs having this as well. I think we won't have to sorry as much about color uniformity as much either with IPS.

Screens: LCD vs AMOLED

The one thing I wish the EVO had going for it is an AMOLED screen. I'm coming from a Nexus one with said screen, and it's gorgeous. Almost useless in direct sunlight, but gorgeous. Now their was an early Sprint ?Coming Soon site claiming the phone had an AMOLED screen http://www.androidguys.com/2010/03/28/sprints-htc-evo-4git-sizzles/ ---but this was prob an error. My question is: is their a huge, noticeable, difference in the two types of screens? EVO owners, give me your opinions!

Just had a live evo in my hands, and the screen is a beaut. I wouldnt worry about it not being AMOLED at all.
The screen is really a great screen.
I really don't notice much of a difference in colors / contrast / etc when compared to the ZuneHD, maybe it's the higher resolution / size that makes it look just as good.
meh, on the whole, AMOLED is all hype no show
AMOLED is trash I have a Nexus and an Evo and in direct sunlight my EVO is noticeable, AMOLED drains battery, LCD saves, colors are sharper but not brighter on AMOLED, brightness all the way up they both match up but the nexus(AMOLED) has a sharper scene
all in all not a big differ and Evo screen (IMO) has a better screen
1- colors are the same but sharper in AMOLED
2- direct sunlight LCD wins
3- colors are both bright
4- LCD battery saver
just a few details!
I thought that the amoled was more efficient.. so better than lcd

Phone Scoop comparesEvo screen to Nexus One Amoled

Screen
The screen on the HTC Evo 4G was, at times, a bit disappointing. Under medium indoor light, the screen is crisp and clear. Text looks sharp and legible and the dark, contrasty interface looks polished. Outside, the Evo 4G couldn't hold up to bright daylight. This made it tough to use for normal email and calling tasks, and nearly impossible to use the camera, since you have to tap an onscreen button to take a shot. In almost every way, the screen fared better than the AMOLED display on the smaller Nexus One. It was a bit brighter with warmer colors and much better outdoor performance. But it could still stand some improvement.

Incorrect, AMOLED has no back light and consumes roughly the same power that a TFT LCD uses just on the TFT portion of the screen. The TFT Portion of a Active Matrix OLED screen controls light on a PerPixel basis, illuminating each OLED pixel at whatever color is required vs LCD where the current is constantly on(except in a pure 0 0 0 black pixel) and controlling the Liquid Crystal portion rotating the LC to whatever degree to allow the backlight(A large % of the consumption) to shine through at a given color. And because of AMOLEDs aforementioned lack of back light it uses significantly less power.
I'm also confused as to what you mean by "color sharpness" Are you talking about the actual edge sharpness of an image or the color reproduction.
In which case the color reproduction on a AMOLED is more SATURATED not specifically more accurate, though the increased saturation makes the image appear better on average because most people enjoy over saturated images. The contrast ratio, which is the ratio of black to white, e.g. when a TV says it has a 3,500:1 contrast ratio then the luminance of a pure white pixel 255,255,255 is 3,500 times higher than that of a pure black 0,0,0 pixel. AMOLED displayes typically have a much higher contrast ratio due to the lack of a back light and the fact they can produce much "deeper" black pixels.
AMOLED actually bugs me, not only are they useless in direct sunlight(which I find myself under quite often) but it feels like colors are often OVER saturated, like the reds and oranges on my friend's Incredible look awful while I've never had that with my Hero, some colors on mine might be washed out but I'd rather have that than have a giant hodgepodge of colors on an AMOLED.
Another thing to consider is AMOLEDs "burn in". That means that pixels that do not change on the screen for a long time tend to burn in and show permanent shadows. This happens on the status bar a lot since it is nearly always displayed and unchanging.
Here is a thread of NexusOne owners documenting it.
http://forum.xda-developers.com/showthread.php?t=673513
As of last week I just switch over from At&t to Sprint wireless. I had two lines on my contract, wifey with the Samsung Moment and myself with the HTC Hero just to hold me off until the Evo release.
From what I thought isn't the Samsung Moment screen also uses the Amoled technology and the Hero is LCD?
Side by side comparison from low brightness to 100 percent, the Hero display looks so much better quality wise compare to the Moment. Hero seem more saturated and crisp whereas the Moment IMO seem much more dulled. Especially in the setting menu with the black background, the Moment is kind of like greenish black whereas the Hero is spot on black. Outside I'm having a very difficulty time navigating around Moment (brightness all the way up) whereas the Hero is still manageable.
By any mean I'm no expert in this display stuff but this is just my own little comparison of what I've seen between the two display.
Anyone know if the Evo screen is transreflective? A related question would be, is it even possible for AMOLED to be transreflective?
I compared my Evo screen with my old Hero screen and the Hero was a little brighter and with darker blacks. Even between LCDs there are differences.

Pentile Matrix reloaded

Most reasonable people viewing the GNote pentile screen say it is bright, has high contrast, deep blacks and a sharp image.
It is a 24bit Millions of colours screen.
So why the hatred of pentile?
It's got me f#^ked.
Maybe it is due to old arguments that date back years.
There is an old controversy going around between pentile and LCD proponents, which is apples vs oranges because there are pentile lcd's and rgb oled's.
The controversy is, that pentiles use less sub-pixels and therefore should be rated as such in lower pixel density.
This ignores how vision works, which essentially is an illusion.
To disagree is to dismiss basic Buddhism and modern psychology as well as film theory on visual perception.
At the level of pixels, the illusion of vision breaks down for lcd as well as pentile screens.
So while looking at a pentile screen with a magnifying glass can be scary, it is the same for rgb's.
So why did Samsung go back to using the pentile matrix instead of RGB for the Note?
Only guessing, but some of the advantages of pentile are;
Cuts power consumption in half for equivalent brightness, or
Doubles screen brightness for equivalent power
Achieves higher resolution
Provides flexible settings for color control and power savings
Increases cost savings potential and yield for manufacturers
Accelerates adoption of next-generation devices
Makes text easier to read
nuvoyance.com
Contrary to the hype, pentiles allow higher resolution, all the while using much less power. Talk about a no-brainer.
One of the limitations of the pentile is a cross hatched pattern seen on the edge of some images, like a border between red and white, when seen up close(with a magnifying glass). This is so at lower pixel densities but "for higher pixel densities you stand to gain from PenTile" ; is the PenTile matrix bad for you?

Achieve higher resolution - yes, but already given a 1280 x800 resolution, would you prefer it to be pentile or RGB?
No one is complaining about pentile can give higher resolution, its not like we want 800x480 RGB over 1280x800 pentile. But already given the phone is 1280x800, people would rather it be super amoled plus instead of pentile super amoled.
While pentile consumes less power, super amoled screens sucks power like crazy. It is a fact. But that said, i still think the screen is gorgreous. however if you let me choose - RGB over pentile any day.

Well if you are not talking about super amoled, then yes a pentile layout consumes theoretically 33% less power.
If you are strictly comparing pentile RGBG/RGBW to RGB, pentile looks like sh*t i gotta say. At least my atrix did.
Pentile also ages better than sRGB amoled, because the lifespan of the organic amoled subpixels are different from color to color. The pentile ages better because there are simply more subpixels of the color which has the lowest lifespan.

The color which has the lowest lifespan is blue, from what i can recall)
How does RGBG or RGBW have more blue subpixels than RGB? (I am only asking just wanted to know.)

Actually I gotta agree with you on that. My gf had a SGS II and that blue tint bugged the hell outta me. I dont know what they done to it, but i dont think it was a problem with it being RGB.
Pentile suffers from strange color tints on whites.
Hard time rendering shades of gray.
Strange artifacts in low-light conditions.
Ofc all noise is camouflaged by the high resolution.
I would trade for the S-LCD screen of the Rezound any-day,
the only problem with that screen is that it could use abit deeper blacks.

I think this is related to OLED and not Pentile.
The Note screen does seem bluish to me when seen from an angle.
I don't see problems with grey on the Note.
I have view gradients to test the 24bit resolution and if viewed in a 24bit app, 24bit images look fine, otherwise not, but this is not an intrinsic fault of the Note's screen, only of the low res images or apps.
I'm not going to go back through and quote people, but some people said some things that are downright incorrect. Pentile does NOT "increase the resolution." It does exactly the opposite, decreasing it. Pentile has half the red subpixels and half the blue subpixels that RGB does; that means overall, pentile only has 2/3 the pixel elements that an RGB screen has. You can't display more information with fewer pixel elements.
The unpleasant artifacts I notice on pentile screens are small text, lines, graphics, appear fuzzy and sometimes colored on the edges, and when I look at solid colors that use red and blue (i.e.just about everything but solid green) especially white, I get this screen door effect. It's almost like there's a bit of checkerboard pattern to the solid color rather than being uniform. Hold your phone closer to your face and look at a solid white area, especially try to find a solid white area that is next to a solid green area with the brightness turned up all the way and you'll really see what I'm talking about.
Pentile doesn't necessarily use less energy than RGB. There are fewer subpixels, but they're twice as large and put out twice as much light. Energy in = light out. So in theory, the energy should be exactly the same. Perhaps they've found some way to do pentile a little more efficiently on some phones, but it's not an overall rule at all.
Pentile is used because it allows them to make the blues twice as big. Since they had a problem with short life span on those, making them twice as big made them hardier, longer lived, and higher yields in the manufacturing process. That's the ONLY reason for pentile. You could say this allows manufacturers to build higher resolution displays than they otherwise would be capable of (since they're cheating and using larger blues than an RGB would have) but a 1280x800 pentile is NOT "higher resolution" than a 1280x800 RGB! According to definition, they're the exact same resolution, but in reality, the pentile is lower in resolution.
RGB is ALWAYS better than pentile as far as image quality. The reason the Note's screen looks better than the SGSII, even though the SGSII had RGB, is simply because it has a much higher resolution. The benefits from that outweigh the negatives of pentile.
Here's a pic I put together showing the differences, even though you can find the same thing elsewhere on the net:
Thanks for summing that up =) Can we go on now and accept Sammy's gone cheap on us?
I really am not too bothered about what screen the phone uses as long as it looks good, i do think to me it looks fantastic. Lovely and bright and it displays a fantastic picture. If people dont like a particular screen a phone uses then they have the choice not to buy it. Some posts in here are very informative so in that respect thanks. However people that ***** about the phones screen (not necessarily in this thread) have the choice to return it and wait for the screen of their choice to come out.

The general public isn't noticing these artifacts, which makes me think they made the right decision on this one. After all, the General public would definitely notice a higher battery drain. I won't pretend to know the technical details about why Pentile battery usage < RGB.

Probably - but it's not interesting if that's not how you generally use your phone.
I wish I could find the interview, but they interviewed a samsung executive who was quite candid about the whole thing. He said quite clearly that Amoled + is sharper than Pentile. But he said that they went Pentile because in terms of sharpness, Amoled is good enough (i.e. still fantastic) - production is better (i.e. it's cheaper to make) and uses less battery power.
And they are correct. I've watched/read many many reviews of the GNote. For the most part, they all rave about the Screen, complain about the price, and are happy with the battery.
It would have been a mistake to put AMOLED+ in, and have the reviews (still) rave about the Screen, be even more turned off by the price, and only be 'okay' with the battery. (perhaps even complaining about it, saying 'Luckily it has a huge battery, because otherwise you'd be toast)
The GNote is already a niche device - you want to widen its appeal as much as possible.
- Frank
Don't get me wrong, I'm very happy with my Note, including the screen. Search my posts and you'll see me say that several times. I'm a long time pentile hater from the day I first powered on my nexus one and started wondering what was wrong with the screen. Yet I've said several times that the Note's so awesome and the screen otherwise so beautiful that I'm able to overlook the pentile layout.
However I'm not going to read people claiming that pentile is better than RGB without speaking up, because it's not.

(This isn't meant to be a hostile response, I apologise if it comes across that way - it's absolutely not intended)
It doesn't directly, no. But you then go on to point out exactly how it enables much higher pixel densities - in an RGB layout each sub-pixel is the same size, so they need to make the blue sub-pixel at a viable size (as you said,) then make green and red sub-pixels that are the same size again.
On a PenTile screen, they can print the blue sub-pixel at it's required size, but the green component can be much smaller - and as a result, you can fit more pixels into the same space. If you compare the Galaxy Nexus's 316ppi PenTile screen to the S2's 216ppi RGB screen, you'll find that the blue and red sub-pixels are actually of a comparable width.
Sure RGBRGB is technically superior to RGBG in terms of image quality, but after a certain pixel-density:distance ratio, it just doesn't matter anymore, and allows for a greater pixel density regardless of display technology.
As a point of curiosity (I know you gave this first point, I'm just elaborating,) resolution is a measure of the number of horizontal or vertical alternating black and white lines a display can produce while maintaining a certain level of contrast. PenTile screens actually are their advertised resolution. However low-density RGBG will lose some detail in reds, but greens are still fine, and the human eye can't see enough detail in blue to tell a difference there. That's in general though - obviously there are biological differences in people, and that is where the legitimate complaints come from - not from holding a phone 3 inches from your face.
As for whether RGB or PenTile is better - consider that the Galaxy Nexus's 4.65" screen could fit either 1280x720 RG/BG pixels, or 960x540 RGB pixels, and it's too dense to be able to tell the difference in sub-pixel arrangement. I think PenTile actually is better in that case.
small dots and big dots
okay so everyone is forgetting that not so long ago printers used to print using
only one size dot of ink. well the picture from same size dots looked grainy. so the print people came up with different size dots of ink to make the pictures look
amazing. i look at the pentile displays the same way. in comparison the
screens on rgb screens look blocky to me and those on pentile look smoother and
less grainy. iphone just shrank the dots to where the human eye can't detect
them. but i believe to acheive the same thing on a larger screen isn't very
pratical. that's where different size pixels will make images appear smooth.
Some great info that dispels some pentile myths can be found here - http://pentileblog.com/uncategorized/pentile-for-720-hd-oled-smartphones/.
Put simply, a lot of the criticisms of pentile displays are only relevant to particular implementations, and not necessarily to the technology.

I looked at the Note screen under a loupe and I could see a serrated edge along the top of white text on a black bacground. If I looked at it normally I couldn't tell. In this case the pentile doesn't bug me.
What DOES bug me is the low color depth that the Note displays. It is odd as it is inconsistant. If I look at photos it is fine. Some apps though look like the color depth is drastically reduced. Two apps to test are Angry birds Rio, and Google Sky. In AB look at the sky and clouds on the title screen, the shades all blend smooth on other devices (checked on an Infuse). On the Note there is severe color loss and much banding evident. Same with google sky There are these sky gradients, smoother on other OLED screens like the Infuse, much more bandy on the Note. I don't know why on some things like photos the note looks fine, but in many apps color loss and banding is evident. Maybe it is some weird incompatibility of the apps? Maybe they mis-read the screen capability and drop to low color mode? I don't know but it is weird and bothers me much more than the pentile matrix.

Screen?

Coming from a Galaxy Nexus, my main concern is - How are the black levels gonna be? I absolutely LOVE SuperAMOLED - Mainly, the blacks - I LOVE THEM and I'm sure many other users do. I don't know if the LG's black levels are gonna be as good or better? Does anything know that?
I have a choice to jump from the Gnex to the Nex4 but if the screen's black levels aren't as good - I probably won't.
What's your opinion about the screen?
Go look at a One X, it'll be similar to that (which is SO much better than the GNex screen - IPS ftw!!)
Yeah but the black levels
It definitely won't be as good. The question is, will it be good enough.
The apparent high end screen on my laptop has a rubbish black level. So I'm also hoping the Nexus 10 has good blacks, so I can use that for media instead.
But did you look at the Htc One X screen, or atleast youtube it?
Sent from my R800x
Yeah I've used the One X a lot of times and I'm not impressed at all. The color reproduction is good but the black levels don't amaze me, at all. I feel that my nexus' screen is much better than the OneX (Just my opinion, don't pounce on me)
With AMOLED, the blacks are black because the led's are switched off, it doesn't try make the colour "Black".
LCD screens do not do this. So blacks will be grey, but colours and viewing angles WILL be better. Another thing, AMOLED is a battery drain with anything other than the colour black.
OLED screens will always have darker blacks than LCDs. That's just due to the nature of how each type of screen technology works.
I very much know how AMOLED works. Guess the blacks won't be that good on the Nex4. :| Hard decision to make now :\

They will probably be as good as any IPS LCD on the market. LG makes very good smartphone displays, including iPhone 4/4S/5 displays.
Just look at the present ips screen on the LG top model phones, i'm sure the nexus 4 will be similar.
The blacks will not be the same as others mentioned but it's a tradeoff. Super amoleds have good contrast and blacks but the ips lcd's I've seen had better color accuracy and sharper images. I like amoleds but the whites and other colors aren't that good and the brightness isn't high enough for my taste. I look forward to seeing the n4 up close

I have mixed feelings as well regarding the screen of the new Nexus 4. I also own a Galaxy Nexus, and aside from the black levels, there is another area where the AMOLED screens shine: motion handling. LCDs tend to blur images in fast motion, motion resolution isn't usually very good. This is very noticeable when watching action films or sports, for example.
However, AMOLED screens are very fast thus their motion handling is on par (or even better than) with plasmas, which gives you crisp and clear images even when moving (blur ocurring depending on the shooting conditions but that's a whole different story).
So, to summarize the differences between the screens:
- The screen of the Nexus 4 will be slightly clearer, the pentile matrix used in the AMOLED screen makes it slightly more "blurry", although due to its high pixel density that's usually hard to see.
- The screen of the Galaxy Nexus has perfect blacks, the screen of the Nexus 4 doesn't. The point is, will its blacks be "black enough" even for multimedia? "Black enough" is very subjective...
- The screen of the Nexus 4 will probably handle motion worse than the Galaxy Nexus one. The point again will be if it handles motion well enough.
It seems that the screen of the Nexus 4 is slightly better for reading and web browsing but slightly worse for multimedia. I only have a Galaxy Nexus (no access to HTC One X, etc) so anyway I can't really compare.
Well it all depend on taste. I think the IPS screen for me will be better for contents consumption. Text clarity is a very important factor for phones and RGB array IPS excel here. Better color accuracy is the most important factor for me, without the banding, retention and dark spots that I deal with on AMOLED. I only fear of the chance of backlight leakage that can happen with regular LCD.
I know the response time of the OLED screen have very fast, but I don't do heavy gaming on small mobile devices. It also have ultra wide angle view and wider color gamut (poorly tuned however). I also like its performance outdoor and contrast. But it can be s battery eater.
Also I missed the curved glass of the AMOLED screen, before anyone say the Nexus 4 screen is curved, by what I see from the verge video it isn't, only the external glass seems to be and just a little by the edge, not the same effect.

The Nexus 4 will have better viewing angles than the AMOLED.
Sunlight will probably be better too. Colours will be more realistic, and battery life will be lower apart from on a black screen.
I don't like the oversaturated colors of amoled screens, and true colors are important in my work, so I much prefer a good IPS screen. Too bad about the blacks though.

I hope the Nexus 4 display will be better. On my Gnex whenever I watch videos with dark scenes or blackground, I get this noise/artifact thing in the background. Do you guys get that? Also, black is technically not completely black on the Gnex because the pixels do light up a little for faster switching. There are a few threads in the Gnex forum that talk about that. It is only noticeable when there is very little or no ambient light. You can test it by going to a dark room and open an image that is completely black. You will see some dim light coming out from the AMOLED.
I would have to say my biggest concern is how the screen will perform in the direct sunlight. Of the phones I've had the gnex does best in direct sunlight. Very easily readable and use able in direct sunlight. All my other phones have been washed out in the sun. They where some form of lcd's, but not any of the newer generation super performing lcd's that are out now. The HTC Rezound I had was the best LCD screen I've owned. Amazing picture but suffered in the sun.

I think that's either black crush like the original note had or the black spots which nearly all amoled screens get because of the way they are produced.

Anyone else want Samsung to go with high quality LCDs instead?

After comparing my Galaxy S6 AMOLED display to an iPhone 6 and an LG G4, the whites on AMOLED just look horrible with AMOLED. Samsung has made tremendous improvements to Super AMOLED technology in a few short years, since the S2/S3 era. Whites look brighter and more accurate, but they still can't touch LCD.
It would be nice to see Samsung go with a cutting-edge quantum dots LCD, we could have brighter whites and still save energy consumption. Due to the inefficiency with the technology to display whites, I doubt we'll ever see them look as LCDs with their back lights.
AMOLED screens don't achieve the best on-screen times either due to most content on the Internet having very high APL. Most of the Internet and UI interface has bright colors and white backgrounds too. Until Samsung can put more development breakthroughs with AMOLED or develop the more brighter and energy efficient QLEDs, I would love to see a high quality LCD with all the same profile calibrations Samsung offers for their OLED screens.

No never. I will not ever buy LCD again, even after the moto x 2014 it became clear to me that amoled is superior. Maybe the whites are still not as good but the blacks are better (and in truth the s6 has the best color reproduction of any display) BUT amoled is functionally so much superior to LCD I would even be willing to give uo some display accurary for the added benefits of amoled (ambient/active display, no power consumption for pure blacks)

X2 for no way. Amoled has those awesome blacks and better contrast. But also, amoled can save battery by using black, dark themes etc since the pixels aren't on when displaying black. That's such a great advantage. Whites look perfectly fine to me too. I see no issue there.

Unless you're going to run your display in negative mode most of the time, most of the content you display isn't going to be black. That's not the design ethos most websites and UIs use. Besides, bad blacks are only noticeable in the dark. Poor whites are noticeable in all types of environments. The color reproduction might be good on Samsung's Super AMOLED displays [not other AMOLED displays] but everything else about them is seemingly underdeveloped. Contrast viewing angles has never been a major selling point for me or a particularly useful additive, high-quality IPS LCDs have proven to be good enough.
LCDs are just better at the moment. Samsung's Super AMOLED technology [again, forget the inferior AMOLED panels used by other manufacturers] is a few years away still from surpassing top-end LCDs. They have the potential though. Just don't see it happening this year. While LG's G4 isn't that great of an LCD, it's a good example of how blacks can be made acceptable on LCDs with quantum dots technology.

Lol, that's funny. How about black wallpaper, lock screen, black theme, black browser theme, I use Voxer all day for work in a dark theme. So yeah, there's tons of places to utilize that. Not to mention amoled uses less power already as is and the newest amoled is super color accurate. There's basically no advantages to LCD anymore. You're crazy, but if that's what you want, buy one. Just don't expect support for it here, where everyone would much rather have amoled. You're not converting anybody (what seems like you're trying to do).

All I heard from you was "blah blah blah, I like AMOLED so I don't care blah blah blah" - not exactly a good argument. Not everyone wants to use a dull and boring dark themes that consist of black. People have different ideas of creativity and most people like to use wallpapers and backgrounds that have regular colors that have bright backgrounds. AMOLEDs do NOT use less power unless content is not above 65% APL. Most web pages and UIs out of the box have 70-80% APL with all the whites and other colors that AMOLEDs aren't efficient with [such as blues] - If Samsung pours in a couple more billion in R&D, Super AMOLED technology might be prime to surpass the current advancements in LCDs. For now, I think and would prefer if they put in a class-leading LCD panel in the S7 and Note 6 for 2016 with display calibration profiles, at least until they iron out their OLED limitations and inefficiencies.

You're kidding right? That literally went the opposite way... I made a perfectly valid fact based response, and you completely ignored/tried to discredit all of the reasons I stated.
And nobody is making anyone theme anything it's just an advantage one could do with Amoled that they cannot with lcd. Also that's an opinion, most people like dark themes better as is.
I guess that's my mistake though, I thought this was a discussion, but it sounds like you're asking a question, and then ignoring everyone's response until you hear the one you want. Is it just me? Am I being an asshole?

Dunno, the fact that 99% of the s6 i have seen have color uniformity issues, ide rather have the lcd. S6 with a iphone screen would be my preferred phone.
Like the other poster said, you always notice the bad whites, the pitch black contrast of amoled you can only really see at night.
And btw i hate ios, and i own an s6. And its the 6th one ive owned because the the horrible pink screen and color uniformity issues.

Which mode was your Galaxy s6 on? Keep in mind both the iPhone 6 and the LG G4 have slightly blue white points. I have no complaints about the whites in the s6.
I used to think Samsung should go with LCDs too, but after the vast improvements with the note 4 and s6 I love amoled displays now.

LCD will never have the functionality of AMOLED, that's even when AMOLED is their color reproduction and brightness are slightly inferior to LCD (which btw is not even true) they lack the possibility for ambient display
I'd vote for LCD on the S6. X100
The display on the S6 is pretty poor to be honest. Colour reproduction is no where near real life on any setting and anyone who thinks it is reads reviews are gospel because in real life it's a different story, with white's are awful and blacks which are only slightly better than the current top level LCD's.
Add to the fact, removing all the nonsense about Amoled being better on battery, which in real world usage is rubbished, most work done on 99% of phones is white background, negating any battery advantage, which is negligible and indistinguishable in real world use and testing.
Black themes on HTC One M9 look just as good as on the S6, possibly even better thanks to the other colours being better, and anything with a light or white background looks leaps and bounds better on it's LCD.
Can't get around the fact that 99% of Samsung's current displays have pink tint and uniformity issues and look pretty poor.
Mine was replaced and the pink tint which looked better, is worse than ever after just a few days or so of use.

Have you even looked at real world pictures or looked through the camera of the S6 lately? No mode is true to life with colours and the my M9, or in fact probably any top end LCD lately is better in direct sunlight. The S6 display looks like a ghost while the M9 actually is still crisp and sharp. As for ambient display, who uses it and how long is it on screen for ? .5 of a second? Useless.
Among the reasons for having bought Samsung phones for years the screen is one of the main reasons, if they changed to LCD I would most likely change brands. Samsung lead the world in AMOLED display so why change that to become like Apple. All I can say to those posing this ridiculous suggestion is change your phone to a manufacturer that gives you what you desire. I still get comments from my friends that have Iphones (the 6 included) that Samsung displays l;ook better so maybe its not that bad at all even if it isn't representative of "real" life its just easy on the eye. My opinion of course

I used to use ambient display all the time, too bad samsung disabled it (for now). And you must be using your display wrong, the S6 has the brightest display by a long margin, almost twice as bright as some of the competition but you have to leave the brightness to auto
No, thanks.
lol, no way, the screen is the main reason I still use Samsung devices...not that the other hardware is bad but OLED is the way to go.
The AMOLED display is one of the main reasons I stick with Samsung.
AMOLED fan here also. Not 100% certain which technology is more efficient/better based on technical specs but for daily usage, I much prefer my S6 SAMOLED over the G3's LCD.

OLED white points and display modes?

I realise LCD displays have better whites than AMOLED, but how warm/yellow should the white point be?
Basic, AMOLED Cinema and AMOLED Photo, the white points look the same, yet Adaptive, I can get cooler whites which I either prefer, or am used to, due to my other two phones being LCD.
