Early Samsung Galaxy Alpha display tests: improved, more accurate AMOLED screen

Early Samsung Galaxy Alpha display tests: improved, more accurate AMOLED screen
The Samsung Galaxy Alpha has broken cover today, and it turned out all we expected it to be: a 4.7-inch smartphone with a metal frame that would most likely rival the next Apple iPhone 6, a device that’s expected to come with a similar size and design traits.

Early reviews (or rather previews) of the Galaxy Alpha have already surfaced out of Russia where Samsung held an unveiling event, and we now have the first details about the display performance of the Alpha. 

First, the basics: we have a 4.7-inch screen of the AMOLED kind with a resolution of 720 x 1280 pixels and a PenTile pixel arrangement. We've talked about the huge improvements that AMOLED has undergone throughout the years, but when speaking about some aspects of it like grayscale accuracy, AMOLED screens like the one on the Galaxy S5 lagged behind rival LCDs.

Luckily, the early tests show that the Galaxy Alpha is a marked improvement in this aspect the grayscale benchmark shows nice balance between the intensity of the three main colors, something that results in a ‘true’ grey that is not green-ish, blue-ish, or red-ish.


Brightness, an area where AMOLED screens used to lag behind in the past, is also not bad (not stellar, though) on the Galaxy Alpha at 327 nits when measuring whites. Gamma also hovers around the industry-standard 2.2 (average value for the Galaxy Alpha is 2.24), being just slightly above that at the maximum brightness levels.

Like in other AMOLED displays, you have various screen modes. The basic mode is the default one and it is the mode that is closest to the industry standards of color accuracy.

In basic mode, the Galaxy Alpha colors are close within the sRGB color gamut. Saturations are just slightly off in this mode, with 100% values being a bit overblown, but others slightly undervalued, but as a whole not terribly distorted.

A look at the delta E values that show deviation from the standard values, we’re seeing some impressive numbers: 1.35 for greyscale and 2.74 for color.


The Galaxy Alpha offers other screen modes that offer different color representations. The photo mode, for instance, shoots for the wider, Adobe RGB color gamut that sees limited use by some professionals, rather than the more ubiquitous sRGB. There’s also the movie mode that stands out with a very cold, blue-ish white point at 7500K and overblown colors. If you stick to the basic mode, though, these early tests show that the Galaxy Alpha display comes with plenty of promise.

Finally, do keep in mind that these are tests performed on what's likely a close to final, but not final version of the Galaxy Alpha, which will launch on September 12th. We'll be running our own comprehensive set of tests on the final phone in the near future, so stay tuned.

Why compromise Nothing can touch Amoled. Samsung still have their SuperAmoledPlus on reserve.

Oh please PA, keep your inaccurate tests and judgements to yourself about display measurements. You said Lumia 1520 has 707 nits brightness and GS5 has 442 nits brightness which is a HUGE difference. So then why in this video GS5 has brighter display ? And dont give me that ....reflectance in the sunlight is due to the glass argument https://www.youtube.com/watch?v=cVm0D_IZz8U

PA is probably the worst at these tests. Let's not forget the whole S5 mess.

But these tests were not made by PA.

I'll wait for Francois Simond to test it.

Why don't you test it our yourself in person when it releases?

Because I don't have the skill and equipment to do the tests. And I don't care enough to go into a store just to look at it lol.

If you want actual unbiased results, stay away from him.

lol WHY? He and Erica are pretty much the most unbiased and critical people in the tech community.

No I'm dead serious. How is she biased? Please tell me because I'm curious to know.

Because she said things that upset the fanboys. Therefore she's biased in their eyes.

Watch Erica Griffin's take on her Tab S review (youtube) She is absolutely spot on with her criticisms. Amoleds just can't render subtle shadows! Samsung likes to twist facts by presenting technical data that an average consumer can never really understand. Is it the best out there? DEFINITELY NOT Super LCD3 anyday baby

SLCD3 sucks compared to AMOLED. Lower brightness, poor outdoor visibility, no deep blacks, and poor low brightness output. The screens on the Tab S and S5 are the best I've seen on any smartphone/tablet I've ever used.

Deep blacks at the expense of not being able to interpret shadows correctly? and how about those neon colors (which are supposedly aren't) , do they look OK and natural to you? yeah, believe everything fanboy... whatever floats your boat.

Erica Griffin is a hack. I'll stick to Displaymate for a PhD with over 30 years experience who actually knows what he's talking about.

"I'll stick to Displaymate for a PhD with over 30 years experience who actually knows what he's talking about." The role of a PhD is often to take in money and then come up with some BS on why something is "good" or "best". He may know what he is talking about, but it doesn't mean what he says is true. This company should be called DisplayTestsForSale.

Do you own a device with latest amoled display? If the answer is "yes" how can you live with such a "horrible" display! Go and throw your phone to garbage can!

Compare the tab s screen next to any tablet with lcd and play the same demo videos and you will quickly see why the tab s has the best tablet screen around

Ok I'm confused. Is the Galaxy Alpha the Galaxy F that has been hyped for the past few months? If so, what happened to the higher resolution and screen size? I'm hoping this is not the Galaxy F.

They have been saying "improved and more accurate" for quite sometime now. hahaha, and fanboiz be like "Amen! Amen! Amoled is the greatest thing since sliced bread" Praise Ye Sammy

Too bad AMOLED surpassed it's rivals in outdoor visibility, brightness and color accuracy. :(
