Display testing and evaluations master Raymond Soneira from DisplayMate posted a comprehensive review of the Super AMOLED displays used in Samsung's latest Galaxy S7 and S7 edge phones. Raymond says that Samsung continues to improve its OLED displays, and its new Super AMOLED displays are the best ones ever tested on a mobile device, surpassing the Super AMOLED used in the Note 5.
The GS7 display (5.1", 2560x1440, 577 PPI) is actually quite similar to the display used in the Galaxy S6, but with some significant improvements - the maximum brightness is 24% higher, and the contrast and contrast under high ambient light has also been significantly improved.
The Galaxy S7 also introduces two important display enhancements. First us is a new personalized automatic brightness control that learns and remembers the display brightness settings that you set for various ambient light levels. The second improvement is the new Always-On Display mode that draws very little power and is quite useful. Finally, it turned out that this is one of the few displays that can be viewed with polarized sunglasses in both the portrait and landscape orientations.
This is no surprise at this stage, but the performance of the flexible OLED display used in the GS7 edge is pretty much similar to the glass-based OLED of the GS7. Of course the GS7 offers a large display (5.5" vs 5.1") with the same resolution (lower PPI).

It's too bad that while Samsung makes great performing OLED mobile displays they still need to use PWM brightness control to avoid burn-in problems and battery consumption issues. PWM(pulse-width-modulation) causes eye fatigue in short time usage scenarios and migraines and eye pain in long time usage scenarios.
LG managed to create a good OLED mobile screen that doesn't use PWM on the LG Flex2，let`s hope they will create new PWM free OLED smartphones in the future.
For more about PWM see tftcentral for the so called “flicker-free” displays or other websites that test displays for PWM like laptopmedia.
Lol PWM on OLED.....
Why not PWM on OLED? Some sites are testing OLED displays for PWM, and almost always they find PWM. Its often 240 Hz. If not at all brightness levels, then at lower ones. I am curious to listen to your arguments though.
there is no "flicker free" except for eInk Panels
LCD never is (maybe the backlight is "flicker free", but the lcd crystalls are not)OLED could be maybe , but at the moment they allways use PWM as far as i know
Saying that improving resolution is pointless is like saying we should stiffle the technological progress because why should we really care, right? The processors are fast enough, cars are safe enough, rockets fly high enough.. why the hell do we need to progress in anything, we're ok with what we have??? The dude has never looked at the screen through gear Vr, 2,5k screen is simply not enough.
The only real limit yo resolution is that it gets as dense as there are many atoms on a flat surface.
