When the Samsung Galaxy Tab S tablets arrived earlier this year,
we were actually pleasantly surprised to find that they were armed with
a new screen mode called 'Basic', which actually did a great job
tweaking the display colors so that they look very true-to-life. That
made us optimistic about the future of Samsung's AMOLEDs, and it also
made us very excited, because we felt that this new, improved AMOLED
technology is to eventually make its way to the company's smartphones.
Ideal color temperature and a relatively low Delta E in Basic mode make the Note 4's screen appear very natural to the eye.
Well, it seems like that time has finally come, as we've been able to take some scientific measurements of the new Galaxy Note 4's
screen, and guess what - its 'Basic' mode successfully adjusts the 5.7"
screen's color reproduction to be impressively close to the reference
sRGB standard - meaning that we finally have an AMOLED smartphone, whose
color tones can get very realistic! Of course, this data should be
considered 'preliminary' for the time being, since the phone is yet to
arrive on the market, which means that the retail product may perform in
a slightly different manner. Still, we believe these early measurements
are a pretty good indication of what's to come when the phablet hits
retail.
Impressively, in this mode, the Galaxy
Note 4's measured color temperature is ideal: 6596 K (Kelvin). That's
pretty much spot-on with the reference value of 6500 K. This means that
the balance between the primary blue and red colors is great.
Thankfully, the third primary, green, isn't present in excessive amounts
(as on Samsung's previous AMOLED screens), so things won't be looking
decidedly greenish on the Galaxy Note 4's display.
With
Delta E greyscale and Delta E rgbcmy values of 3.84 and 4.86,
respectively, the Note 4's screen proves that its various hues and
nuances won't deviate much from their target values. In the realm of
Delta E, which is a metric used to indicate amount of 'color error',
figures of less than 5 are generally considered fine.
Well, figures of 3 and below are to be preferred (Delta E of 1 is
considered to be the smallest amount of color difference a human can
distinguish), so there's obviously still some room for improvement, but
even now, the Note 4's measurements speak positively about its overall
color reproduction.
As you can see on the chart
to the right, the measured color points are very close to almost all of
their reference values (the squares) - that's a good way to visualize
the level of color accuracy exchibited by a display. So, what else can
we say but 'well done, Samusng!' Of course, should you wish to feast
your eyes on the traditionally oversaturated and vibrant AMOLED looks,
you can always switch to some of the other available modes ('AMOLED
cinema' and 'AMOLED photo'), as those will present you with the
familiar, punchy AMOLED outlook.
As a side
note, we'd also like to mention that the Galaxy Note 4's display will
easily be able to achieve a maximum brightness of about 500 nits and up
when in excessively bright lighting conditions, so we expect outdoor
visibility with Samsung's next-generation phablet to be more than
adequate - just as it was with the Galaxy S5.
