Finally! Galaxy Note 4's Super AMOLED screen to have super-accurate colors

samedi 6 septembre 2014

We've always been honest that one of our biggest gripes with Samsung's Super AMOLED screen technology is how inaccurate and pumped-up its color-reproduction tends to be. As undeniably eye-catchy as those ultra-vibrant visuals are, we've always imagined there to be a special screen mode that would allow Samsung's AMOLED-powered devices to exhibit more realistic screen tones. Sure, phones like the Galaxy S4, S5, and Note 3 came equipped display modes designed to make things look more 'natural', but truth be told, in reality, those modes never did much in order to fix the issue of AMOLED's overly cold and greenish color character.


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!



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.
