With the Galaxy S6 and S6 Edge, Samsung brought some much needed improvements to its flagship platform. These range from performance, in the form of the Exynos 7420, to the design and build of both the S6 flagships in the form of a metal unibody. Today’s post however relates to the display on Samsung’s devices complete with benchmarks and figures, so to gauge exactly how much things have changed with this year’s Galaxies and what exactly Samsung’s display improvements consist of.


Starting from brightness, Samsung claimed that the Galaxy S6 flagship duo can achieve an astounding brightness of up to 600 nits. A claim that sounded high when it was made, tests do end up confirming Samsung’s word, at least when both the devices are run on auto brightness mode. Manually, you can’t make the brightness on Samsung’s flagships exceed 335 nits as can be seen in the tests above. This is in place to improve power efficiency probably. But in auto mode, we see the brightness on the Galaxy S6 Edge exceed even the 600 mark, while the Galaxy S6 also manages to outperform its counterparts. Auto mode will also mean that your device’s battery won’t give you a long life so bear this in mind if you’re intent on achieving the maximum amount of nits of brightness possible.


Coming towards contrast, just like the Galaxy S5, Samsung’s Galaxy S6 and S6 Edge seem to be more biased towards green color reproduction. Aside from that, overall RGB balance appears to be at par and when both of Samsung’s devices are compared, the Galaxy S6 Edge appears to be more balanced at color reproduction, when compared to the S6. Gamma points for both the devices are almost the same, but deltaE ratings, particularly for the Galaxy S6 present some interesting information indeed.

As can be seen above, detaE ratings for the Galaxy S6 manage to cross four, and even touch five in a couple of occasions. While ratings of deltaE above four are visible to the human eye, in this scenario, lower is always better, and in this aspect the Galaxy S6 Edge seems to outperform its counterpart. Samsung really does seem to have paid more attention to the Galaxy S6 Edge rather than the Galaxy S6. Even when we take a look at White Balance and average deltaE scores below, we see that the Galaxy S6 Edge has the better numbers, even though both the devices remain to stay at acceptable levels of display statistics.




Moving towards grayscale readgings for the Galaxy S6 and S6 Edge, the Galaxy S6 Edge turns out to be more netural and balanced in overall grayscale balance, when compared to the Galaxy S6. Both the devices also seem to be a bit more predisposed to green and the Galaxy S6 is a bit more warner, and while both the devices manage to loose out to the iPhone 6 in overall saturation, Samsung’s devices are right there at the top anyways. Take a look at complete saturation readings and scores below.

Color Accuracy

Moving towards color accuracy, once again the Galaxy S6 and the S6 Edge do not end up disappointing. Looks like Samsung has paid quite a lot of attentions to the display on its devices this year, as once again both the devices, particularly the Galaxy S6 Edge seem to top color accuracy scores in the Gretag Macbeth Colorchecker. Samsung’s AMOLED displays have not disappointed this time around, despite some discrepant deltaE readings earlier on. Only Apple’s iPhone 6 manages to top the Galaxy S6 Edge in overall color accuracy. Take a look at it below.

Saturation & Conclusion.

Color saturation on the Galaxy S6 and S6 Edge paints a similar picture as color accuracy does. Samsung seems to have paid a lot of focus on its devices’ display this time around, as the colors on both the Galaxy S6 and the Galaxy S6 Edge are very well balanced on the screen indeed. The calibration manages to strike a near optimum balance between the three color components and shows Samsung’s advancement in manufacturing displays, particularly for its flagship smartphone series. Take a look at color saturation balance on both the Galaxy S6 smartphones below.

Concluding our display analysis of the Samsung Galaxy S6 duo (scores and tests courtesy of Anandtech) we see a vastly improved Samsung display, particularly for the Galaxy S6 Edge. Looks like Samsung’s decided to pay more attention towards the Edged variant, perhaps in an attempt to gauge market response for curved edge smartphones which would give the company better design options for future devices. What concerns us more is that how this high brightness rating, increased resolution and other specifications on both the devices will end up impacting the Galaxy S6 and S6 Edge’s battery performance.

While 14nm does offer improved power consumption, but display resolution upgrades tend to have huge effects on consumption even with the smallest of tasks. And given Samsung’s choice of non-removable batteries this time around, how will consumer satisfaction be affected if battery performance does indeed fail to impress? We’ll find out more as the devices start to become available next month. Pre-orders for the the Galaxy S6 duo have already started, so go book yourself a device if you haven’t already done so.
