Samsung please increase the frequency of the PWM to such values ​​that the amplitude don't drops to zero.
Just make all the same as in the samsung amoled displays of Fly IQ444 Diamond 2 Quattro and Motorola Razr HD, and lg amoled displays of lg G Flex.
This flickering is harmful to the eyes (especially at low light). It appears at 70% (and below) brightness

The same situation exists in all other amoled samsung smartphones, search "galaxy s3/s4/s5/note etc. flickering"

What he said. ;)

DisplayMate makes the equipment used to test displays of all kinds across industries. They do exhaustive tests on smartphone displays and the Note 4's is the reigning champ. Even outperforming both iP6's.

Here's their evaluation. Everyone can draw their own conclusions.

If you do not know about something you always call it trolling?
I always write objectively with facts and proofs

I am not writing about the color reproduction.
The fourth time you answer me, and the fourth time you writing not in a subject

Why don't you provide some more scientific evidence rather than just posting some random youtube videos (measurements, etc.)? I have never seen an amoled flicker myself so measurements would be great. And I really don't understand what scientific basis you have for saying that any sort of flicker is harmful for the eyes. :confused:

maybe if he actually OWNED these devices, his posts would be more credible, but he just posts crap he gleans of the internet, and tried to represent it as actual fact..

not worth bothering with him any more, he is just a troll

This is the scientific evidence.
Search "PWM flickering", "PWM"

Thanks! But how would that affect the battery life? I also don't think it is a large enough problem for most people, as none other than yourself and maybe a few others have reported any problems (think it is basically the same as seeing rainbows on DLP projectors; some see it, some don't).

Also, if the x-axis on that graph is in ms (milliseconds), it is obvious that at worst the display is turned off for 2ms (1/500th of a second), and that is way beyond what a normal human being would be able to notice.

Oh, and I would also like to see a comparison to other displays as most LCDs these days have LED backlights that also flicker; doubt the guys over at Oculus would have picked an amoled display if the flicker was that bad.

Can you explain to us poor dumb slobs what this means to the average person? Maybe state your case of why you think this is a bad thing? I was under the impression that all lights flicker - alternating current and all that.
When there is a total damping to zero it is harmful to the eyes. In the long reading on the average and low brightness appears eye fatigue. Over time can be reduced eyesight. Perhaps there is an impact on the brain and psyche.

of course, eyes don't see it, but such damping is harmful (wrote above), even in the review its written

here again, prove to us that you actually OWN these devices; we dont need someone here who just constantly posts negative things you find on the internet, without having a shred of PERSONAL accountability about what you are posting. Anyone can find negative things about anything via google, but unless you can personally vouch for any of crap you are posting, no one here cares or wants to see it any more.

Oh and by the way, I am amused you think that "reporting" me, exposing what you really are is going to gain you any sort of credibility. People here know what you're up to ..

How would it affect to the objectivity?
No proofs only "personal feeling" is better than the tests and research scientists?

I wrote the mods about you too. You pick random findings from questionable sources then post them without context solely for the purpose of antagonizing people and goading them in to arguments. You've been run out of every thread you've done that in because it's pretty transparent.

The reason I referenced DisplayMate is that with their mastery of display science if what you posted was in any way relevant they would have certainly caught it. They are credible to me. You are not.
