Samsung Galaxy S6 edge Super AMOLED display benchmark and color accuracy analysis

The Samsung Galaxy S6 and Galaxy S6 edge both feature a 5.1-inch Super AMOLED display that Samsung boldly claimed is among the very best displays out there in terms of not just its high resolution, but also quality. The part with the resolution is fairly straightforward: you have a 1440 x 2560-pixel (Quad HD) display with a pixel density of the mind-boggling 577ppi that looks surprisingly similar to paper.

Sharpness, however, is just a part of the story, and even a sharp display could look bad if the company does not take care of proper color accuracy. The Samsung Galaxy S5 was a perfect illustration to that: its high-res display appeared noticeably greenish and with overblown colors, it was far from accurate. Has the company learned from its mistakes, and is the Galaxy S6 edge an improvement?

We have run the first display benchmarks on the pre-release units shown at MWC 2015, and we're happy to say that the answer is 'yes'. The Galaxy S6 edge display is not perfectly color-accurate, but it is very, very good and features pleasing colors. As you probably know, Samsung provides multiple display options where you can tweak the colors, and we measured in the default 'basic' mode that is supposed to be the most color accurate.

What do we notice? First, gamma response stands very close to the reference 2.2 value at 2.3, which means we have adequate brightness response at various levels.

Color temperature measures in at 6971K, which is a bit above the reference 6500K, and what this means is that whites would appear a bit blueish. It's not a huge deviation, but it is noticeable. 

Colors are mostly pleasing, but not perfectly accurate

When we look at color accuracy, gladly, in Basic mode, the Galaxy S6 sticks to the standard sRGB color gamut. We see an above average color deviation in both greyscale and color tests. You can see on the saturation sweeps chart below how the dots for particular color are not perfectly within the squares where they should be. As we said earlier - colors are mostly pleasing, but not perfectly accurate.

Finally, we don't yet have the number for peak brightness, as the conditions were too challenging on the MWC floor, but we can say one thing for sure: this display is bright, above 500nits, which is an excellent achievement for an AMOLED display. Take a look at the measurements for yourself right below.

I'll wait for what others say, such as DisplayMate. Funny because last year they ranked the S5 as the best screen they tested and PA ranked it terrible. Just saying.

Exactly ! PA's display testing methodology is a joke. According to PA,

Lumia 1520 - 720 nits
Galaxy S5 - 442 nits

Yet in real world the difference is huge. Look at this video and see how Galaxy S5's display in much more brighter and legible then Lumia's in day light.http://goo.gl/lIJXaD

PA said the M8 had a way better screen than my S5 and that was a complete lie. The M8 sucked when it came to outdoor visibility. The S5 blew it out of the water, which is partially the reason why I got rid of it.

I am shocked at the gray scale where they put the S6 as average. When AMOLED screens can go lower and have much deeper blacks and greys then any other type of display. Even PA stated that the S6 has excellent minimum brightness.

Do you even know what you're talking about? Grey scale isn't the same thing as blacks.

You actually can't compute the max. brightness of an AMOLED panel. It depends a lot on the APL( Average Picture Level) and Samsung has another trick to disable max. brightness in manual mode.

Both of these make it nearly impossible to measure max. brightness of an AMOLED. PA is not at fault here.

At 100% APL, S5 reaches about 450 nits and at 1% APL, S5 reaches 700 nits.

See this for more info:

http://www.anandtech.com/show/8795/understanding-brightness-in-amoled-and-lcd-displays

Also, in the video you mentioned, there is the measure of sunlight performance. That includes another variable i.e. reflectance into the equation. OLED panels are thinner and hence reflect a lot less light making them a lot more legible in direct sunlight despite having lower brightness. See GSMArena's sunlight legibility test:

This rinky-dink tech websites (PA included) don't know how to properly measure the performance of displays. Out of every measurable benchmark, "maximum brightness" is the easiest to measure. Yet, PA still can't get it right.

The SG5, Note 4, and SG6/6e all have adaptive displays. So, in very bright ambient conditions (sunlight), their displays output over 650 nits (Note 4 does 750). Why can't PA and other wanna-be tech publications get this right? Lack of training? Lack of insight? Lack of common sense? Who knows?

G3 was good. But the furthest thing from best smartphone of 2014. 2015? Not a chance. The G4 would have to be majestic. A marvel in hardware and software to compete with the S6 and for damn sure the Note 5.

Don't get me wrong, I love LGs hardware/software (I've never owned a phone not made by LG), but from what I've heard, the G3 was meh as a flagship due to poor performance and subpar battery. I'm not calling it a bad phone, and because I've never used one I'm not going to call it a bad phone, but at the same time, those flaws keep it from being the best, in my opinion. Best smartphone is highly subjective, as various users have various needs.

Matter of opinion. I'd give best smartphone to Note 4 hands down. Sorry to cheat on my 6 Plus but that's the honest truth.

Look, I have the G3 and I love it. Great phone, and I do not regret the purchase. But it IS flawed. I am surprised that it has been voted the best smartphone of 2014. The Note 4 would have received my vote.

No data for maximum brightness. Okay... From what I've gleaned, the display is a regression from the Note 4.

I wouldn't say "vastly" improved, but improved nonetheless. This graphic from PA, however, indicates otherwise. Guess I'll wait for Displaymate's review.

It is possible to lose some accuracy in pursuit of brightness and power efficiency. Not everything improves simultaneously.

Yeah I'm very disappointed that both the display and camera look like they've gotten worse than the Note 4, those were the two things I was expecting to be same or better, and most important to me.

Yes we all know its bluish, but that was on purpose and you can change the white balance to your likings to get accurate results (can you do that on the iPhone?)
I actually got used to the blue tone since it give the illusion to be brighter

I've never liked or wanted any phone that wasn't black or dark grey, but the green does look great. I might choose that color if I were considering the S6. I'm not, because I wasn't to see what the Note 5 will offer. As amazing as the Note 4 is,I can't wait to see that beast.

The Z3 has a 10k temperature, but the screen is 97% sRGB and what PA is referring to overall, so yes it "isn't bad" at all. The only joke is you.

WOW you S-fans need to understand reality. IPS is used professionally cause of many advantages

S_AMOLED is good tech but has weaknesses , it's universally accepted that the white levels will never reach a IPS Lcd with good calibration.

And yet, the Note 4 had some of the best whites out there. Even the S6, by PA's testing has better white accuracy than the iPhone.

Not that I trust PA's numbers, they're just cookbook technicians, who download a program and run it and don't have any real knowledge about the subject matter. I wait for Displaymate to weigh in on this display

Are you stupid..? Do comapare an outdated technology(LCD) with the new one (LED)..loll
Super amoled over ips:
1.thinner, lighter
2.way more power efficient.
3.life live colors.!! No washed out colors, led doesn't have backlight and ips can't produce deep black!
4.best contrast. .ips never ever can match!
5.more better sunlight visibility. (LCDs are more reflective)
6.better viewing angles.
and so on..
Ips over Super amoled
1.cheaper
for more information you can go to Displaymate and increase your information.

You are, sorry to inform you, an idiot. AMOLED is superior to IPS LCD in every single way. You should know that Samsung has a LCD factory as well, and if they wanted they could easily make IPS LCD dispalys for their phones, but they choose the far superior technology. The only reason OLED isn't used in desktop applications is that there are no monitors available except super-expensive, super professional ones from Sony.

Sorry to inform you, but you are the uninformed "idiot". Samsung has an LCD plant but it's far behind generation wise to companies like Sharp. Samsung doesn't use LCD panels in flagship phones simply because it's their product differentiation strategy.

OLED isn't used in desktop applications, because the color gamut can't match IPS panels yet. Blacks maybe superior, but black is one of the most useless things for graphics designers. SONY makes a medical OLED panel, not because of color accuracy but because of motion blur, and that's about it.

the white point temperature matters a lot cause most apps like mail , web browser use white background , AMOLEDs appear slightly bluish , which means it's definitely noticeable compared to a quality IPS screen like the iPhone's display.

a lot of AMOLED supporters here, but as I've said IPS is far more used professionally and I personally prefer the use of IPS.

either way lets wait a few years down the lane and lets see if IPS LCDs get replaced by AMOLED in professional Apps and desktops , I have a feeling they won't be replaced so easily.
atlas all the problems with S-AMOLED gets fixed.

Actually IPS have a colder temperature and hence are more bluish. AMOLEDs like the Note 4 are closer to D65 whites.

There is no native white temperature inherent to each technology. It is how you calibrate. iPhone 6 has a very high white temperature but apparently consumers do not care.

Firstly how can you tell what 2nits looks like just looking at it, and secondly you can't get those results without fiddling with things like auto-brightness settings.
