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.

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.

hey! just put simply "your opinion" rather than "most people". What evidence do you have? Unless you are "Prof Charles Francis Xavier".

Nice to hear Samsung is improving OLED based displays. Hope that one day other big OLED problems will be solved also.

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.

Anandtech never said S5 Amoled is accurate.they said the opposite

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)

At first it was the brightness, then the color accuracy, and now it's the green tint. What next? Blacks are too black? Too sharp? Too perfect?? LOL Can't wait for next excuse.

The greenish of PA's unit is due to the quality variance issue, It's a faulty unit. Most Galaxy S5s don't have that greenish issue,

See what iAnand will write about iPhone6 obsolete display tech.

Props to Samsung for developing this technology and just in few years surpassing a technology that was developed 40 years ago. Take a bow !

p.s. Come on Erica Griffin, review the damn display of GS5-A LTE already!

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.

odd that you say that the G3 loses 30-40% brightness - my G3 is soooo damn bright, that I turn it down - my last battery charge lasted 24hrs for me....

Samsung has always had great screens in both smartphones and tablets haven't seen the tab s screen yet but I'm assuming it's just as great as my note 3's

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.

They should keep the Galaxy name for either flagships or non-flagships, not for all their androids, people think that a "Galaxy" is a cheap laggy phone

If Samsung wanted this one on the First Galaxy S5 Why?couldn"t the Galaxy S5 been delayed until the Screens were in Full Production,Samsung do not seem to thing about consumers who have invested into the Galaxy S5 an some will be very angry been let down by them

Look at the # of Galaxy S5 units sold right now, Samsung is better off as a company because of that
