Samsung's first AMOLED Quad HD display gets analyzed: further improved color accuracy, not that green any more

Posted: , by Victor H.

Samsung has made great strides with its AMOLED displays in recent years - from the dim and not very color-accurate displays in the first smartphones with AMOLED screens to Samsung Galaxy S5’s 1080p Full HD display that is fairly bright and has improved (but not perfect) color accuracy. Now, though, Samsung moves forward with its first Quad HD (1440 x 2560-pixel) AMOLED display, first seen on the Samsung Galaxy S5 LTE-A model, a device only sold in Korea, but surely soon coming to more models all over the world.

AnandTech is now the first to analyze the colors of the Galaxy S5 LTE-A’s 5.1-inch Quad HD display, and the results show continuous improvements in AMOLED.

We've already talked about the difference in sharpness between a Quad HD 1440p and a Full HD 1080p display, and how it’s practically insignificant unless you stare at the screen from microscopic distances. What we’re much more interested, though, is color accuracy.

The Samsung Galaxy S5 has an overwhelming green color that does not fit the industry-standard sRGB gamut, so the overall effect is of bluish and greenish colors (not perfectly calibrated).

However, Samsung has seemingly made some improvements in the GS5 LTE-A, so the screen does not appear that green-ish. The key word here is ‘that green-ish’, as while there is improvement, the first analysis shows that green still dominates other colors.

Notice the green bar in upper right on both charts - the Quad HD AMOLED (on the right) is better balanced than the very green-ish 1080p AMOLED on the Galaxy S5 (on the left, in Cinema mode)

For all else, white point is even closer to our reference point (of 6500K) at 6429K, and grayscale accuracy is the best of any other flagship smartphone. Moreover, color saturations are also very accurate, with deviation of as little as 2.92.

Obviously, the power consumption of a Quad HD display will be higher, but for all else, it seems that Samsung has made AMOLED even better in its new version, and we’re looking forward to seeing it in upcoming devices like the Samsung Galaxy Note 4 and the rumored Galaxy F.

So is Samsung the King of Screens?
LG G3 is QHD just like the Galaxy S5 LTEA

Every report shows different results i don't even know what to believe anymore
i'll just believe my own eyes.

Put simply, for most people it should still appear green-ish and LCD displays on phones like the iPhone 5 and HTC M8 should have slightly more appealing visuals. It's better than the S5, but Samsung still has to balance out the colors (color accuracy is already nearly perfect).

We'll give you our detailed analysis as soon as we have the display in our own labs, which should happen in the near future, so stay tuned.

Yes I agree. These improvements are breathtaking. The level of improvement from the Original Galaxy S to these new Super AMOLED's are staggering.

I am completely stoked about a Water/Dust proof Galaxy Note 4 with this insane technologicaly impressive 5.7 inch 1440p Super AMOLED display.

Samsung has improved how OLED is used in displays. In other words Samsung has improved display's technology. But it would be nice if Samsung could improve and OLED technology by it self. Because biggest AMOLED problems lies in OLED technology.

That Ray S. makes one of the worst reviews I have ever seen it´s something I have come to expect.
That you quote him on it it´s really dissapointing.
The issue with the "greenish" screen is related to the fact that Ray S. decided to test the GS5 with the default mode ("Standard") instead of the one that has the greater color accuracy: "Cinema mode".
Any other site is reporting great color accuracy in the screen (better than most LCDs), including several with more experice in displays, like Anandtech, Displaymate and Gsmarena.
So that you see I´m not bluffing I let you the links:
http://www.displaymate.com/Galaxy_S5_ShootOut_1.htm
http://www.phonearena.com/news/Samsung-Galaxy-S5s-screen-is-far-from-the-best-heres-why_id56255
If I were you I would correct yours and Ray´s posts in a exercise of profesionalism.
I would have contated you anonymously, but there is no button to correct the posts.

Funny, that´s not how I understand this sentence:
"Overall, I’m quite pleased with the display. The AMOLED display in the Galaxy S5 is finally equivalent to LCD displays in color accuracy and peak luminance, areas that LCD used to be the best in."
Not to talk about the White Point average of 6541 and not 8183 like phonearena reports (best result is 6500)

The best thing is, while the G3 QHD loses about 30-40% brightness and draws just as much more power due to the way IPS subpixels are being lit, according to PocketNow, the S5 LTEA with the QHD has the exact same long battery life as the S5 FHD, which justifies the higher resolution panel. And that is with twice as many pixels and beefier specs. Simply put, AMOLED gets ahead the tighter subpixels get.

C'mon Samsung, only 3 things that can boost further their sales:
1.Put S-AMOLED to low-mid range Galaxy.
2.Use at least Snapdragon 200(Cortex-A7/Adreno 302 variant) on low end Galaxies instead of crappy unknown single core chipset and also WVGA display instead of HVGA.
3.Make an innovative and distinctive design on Galaxy smartphones.

Let me quote from the overall result in a recently posted screen comparison test;
http://www.phonearena.com/reviews/Screen-comparison-G3-vs-Xperia-Z2-vs-Galaxy-S5-vs-One-M8-vs-iPhone-5s_id3747/page/4
"The screens of the LG G3 and Galaxy S5 are the ones that remain slightly behind those of their opponents. The main problem for the G3 is the slightly worse outdoor visibility, while the Galaxy S5 suffers from inaccurate color balance."

And quote from this article
"The Samsung Galaxy S5 was calibrated very well with color saturations nicely spaced and the white point hitting a point close to the industry’s 6500K ideal (a temperature that hits the right balance - not too cold, nor too warm)."

The screen test, S5 got lower scores epecially in the color accuracy scores while in this article they claim S5 got the best screens. Undoubtedly, S5 really has awesome screen but why did PA aint got no word of honour. Undecided if S5 has really have the best screen? Did someone missed the memo on what should be the best screen?

Because a great screen is just more than accuracy of colors what about contrast and great viewing angles I think most people will notice lcd screens look washed out in terms of colors next to super amoled the choice is yours of u like the punchy colors or not. How about viewing fhd videos on these android phones with 1080p screens or higher and compare it to a non hd screen like the 5s and can they honestly say the bids look better on the 5s screen?

Still there are people who do care about color accuracy. If you don't care about color accuracy good for you, but then someone can say they don't care about "true blacks", viewing angles, punchy colors etc. Display needs to tick all the boxes if it is to be called the most accurate.And Samsung was marketing S5's display as most accurate which it clearly isn't. If they were marketing it as best mobile display or something it would be okay since their sales numbers would back up that story.

Well when the displays are one of the most practical displays out there, I don't know why most people would care that much with Colour accuracy as much as PA addressed. I mean, I am not in sheer denial that AMOLEDs were not colour accurate, but I never agreed with PA who always mark S5's displays bad (Worst out of the flagships) just because of Colour accuracy.

49. avalon2105 (Posts: 111; Member since: 12 Jul 2014)


Maybe not the worst, but color accuracy is not it's only problem. All the other screens are much sharper due to full RGB matrix while S5 has Pen-Tile, also it is noticeably dimmer than likes of M8, G2 or 5s, they all have cca: 650-700 nits of brightness while S5 can output barely 440 nits on full white background. I personally only care about 3 aspects of display quality, sharpness for obvious reasons, color accuracy to see content the way it was intended (and not to see green tigers) and maximum brightness for outdoor visibility. If you take those into account S5 would be the worst and I guess that PA has similar priorities. On the other hand, is Samsung puts AMOLED sign on a piece of sh.it GSMArena will claim it "The best display there ever was". In the end you shouldn't trust either, but check the phone for yourself and see if it "rocks your boat".

'All other screens are much sharper due to full RGB Matrix', sharper, true, but 'Much sharper'? No. I do not see any sharpness difference unless I pay a very close attention of those AMOLEDs and LCDs. You could however back up your claim with a suitable evidence/proof.

'Noticeably dimmer', since I only care about outdoor visibility I won't really take this as an issue (As you know, Outdoor visibility is something to be desired with AMOLEDs, stated by PA earlier). But even if I or other people take a very important attention towards brightness I wouldn't say it is Noticeably dimmer. Both PA (http://www.phonearena.com/reviews/Samsung-Galaxy-S5-Review_id3639 ) and gsmarena (http://www.gsmarena.com/samsung_galaxy_s5-review-1064p3.php ) does not state that there are a big difference in terms of brightness. Both are from the reviewers whom you take attention to.

So IMHO, not as bad as you described.

Excuse me on #44 however, I was too sleepy and wrote that claim. You could probably tell by my incorrect grammatical construction.

53. avalon2105 (Posts: 111; Member since: 12 Jul 2014)


For "sharpness test" it is best to take two phones, one Pen-Tile, one RGB with same size and resolution (like S4 and M8) and open same webpage with lot of small text if possible through same browser (like Chrome) to eliminate browsers text rendering as variable. I did it last year with S4 and Z1, and Z1 looked much sharper TO ME.
On brightness front, S5 has max brightness of 529 nits (according to GSMA, PA rates it at 440 nits) while G2 has 667 nits of brightness. I don't know about you, but I would say 138 nits of difference (or 26% if you use S5s brightness as 100%) is noticeable difference.
In the end I said it is bad in my experience (bad for my needs). Someone will consider it the best screen for deeper black levels or better viewing angles.
In the end, regardless of numbers posted by any review site, when I compared S5 with my G2, G2 looked much brighter and much sharper when displaying fine text. I do a lot of web browsing (mainly white backgrounds) and my theme/setup is always white/light so AMOLED would look bad and loose its advantage in battery consumption.

The only bright screen here is the G2, and it's basically the best LCD out there (shame to what happened on the G3 however). The others are pretty much close (does not exceed the 15%) mark.

I am not sure about how you translate sharpness, but I don't really want to agree with you... I don't See any Meaningful difference at all when Comparing those two types of displays.

55. avalon2105 (Posts: 111; Member since: 12 Jul 2014)


Like I said, my preferences are my own, and nobody should trust me or reviewer blindly. Since it is only a way I use to measure display sharpness I put sharpness test into quotation marks.
You said it right in "I am not sure how you translate sharpness", since there in no measuring unit saying this display is 1,4XYZ sharp and other one is 1,6XYZ. There is PPI, but it doesn't tell you the whole story since stuff like different matrices can influence it.
And G2 is certainly not the only bright LCD display, iPhone 5 has 640 nits and M7 (in one of my previous post I put M8 by mistake) has 647 nits. And if we are going to compare the best of AMOLED it is only fair to compare it to best LCD displays out there, and not the likes of Xperia Z or similar.

Different matrices can actually matter or not in terms of sharpness. And IMHO in this case it is mostly not. But I don't want to really claim something just yet, Just as of now I am not seeing any differences between them, therefore I question your observations.

As for the brightness, You are right. But I would point out that against current flagships, Samsung is the only very few that actually improves it's brightness.

Oh yes, as Post note I actually would choose LCDs over AMOLEDs (Hence my favourite are the G2's display and I actually want LCDs to be better), but I can clearly see that AMOLEDs are chasing really fast. They are improving it's strength while addressing their weakness very well. Hence, I could easily say that it's very practical as of now.

Same old washed out colors and viewing angles. Nobody complains about them because it will hurt sales of apple since they also use such screen tech. If apple used AMOLED it would have been the best screen of all time for tech sites. Biased hypocritical people. It's so annoying

I admit I was often the first one to sh** on anything AMOLED related but those screens are starting to look good even in my book. If only Samsung could find a way to use RGB matrix instead of Pen-Tile, and increase brightness without additional battery drain it would be awesome. Still the screen on S5 looks terribly dim to me compared to good LCD screen. On a side note, why are people so anal about viewing angles, what is a benefit of having better viewing angles when you always look at your phone dead on? I understand why is it important for TVs and monitors that are pretty much stationary/unmovable but you can always shift your wrist couple degrees to get perfect image on a phone.

I've probably phrased that one wrong. What I mainly meant was that LCD has similar energy consumption regardless of color being shown but AMOLED just goes full retard when trying to display white color. That is also one thing that bugs me about battery tests. They say "Samsung Galaxy S5 plays video for x amount of hours" without mentioning what video. Again, on LCD it doesn't matter much but on AMOLED it clearly matters are you watching Batman Trilogy of some documentary about Antarctica. What I would like to see is AMOLED displaying white without any tint and without using "fuel" like Hummer H2. Hopefully, you'll realize what I was trying to say even if my English is kind of bad.

I prefer oled over lcd any day. What I don't understand is, if Samsung can build a Quad HD RGBG screen, why can't they build a Full HD RGB screen? Wasn't the problem in 2011-2012 getting the blue subpixels small enough for long term reliability? Maybe the Sony Z3 will have the RGBW TriMaster Oled display. If Samsung or Sony (or anyone really) would build a IGZO OLED with RGB, that's what I would like to see.

Oh, but until I can get an RGB OLED display, I'm going with IPS LCD. The colos are just too much better.
