Amoled black dots in dark?

**Craig Rogers** · 03-13-2013, 07:14 PM

Okay, so I've been noticing black dots on my Amoled display with a low lit display while in a really dark room with a dark image or something on the screen. It isn't a problem for me because if you turn the brightness all the way up, you can never see them. I know this is a defect with all the Amoled displays, but I mean what the hell was samsung thinking putting an Amoled display on the s3? This is a huge defect (even though I love the Amoled display, I think it's better than ips plus or whatever it is), I would think samsung being a huge company would hold off on Amoled until this problem was sorted out. What are your thoughts on this problem? Have any of you experienced these black dots with your display?

I don't have this problem... If you do, I am sure under warranty it will be replaced.

You are one of the lucky ones for not noticing them yet. Every Amoled display has it, it's just the right conditions needed to see them. If you go and downloaded dead pixel tester Amoled on the play store and go into a dark room with the app running you will see the dots. Oh and it has to be like a grey or black background

Sounds like I'm one of the lucky ones who will never encounter such “right conditions" in my lifetime. Unless I grow a liking to spending some quality time with a dead pixel tester in the dark.

I have def. noticed this too, but only under extreme conditions where I am in a completly dark room with a completly dark screen. THey look almost like ink blotches.

When I first noticed the dots on mine, I had printer ink on my fingers and I thought I got it all over the screen. Scared me half to death, because I just got the phone. Does anybody know exactly what causes these dots to appear? I've heard it's a manufacturing malfunction with one of the dropping or overlay processes, but I'm not sure.

Thanks for the heads up.... I did run the test several times and found no problems with my phone.

I guess I don't see the issue, since if I'm actually using the phone the screen will never be completely dark. Reminds me of camera forums, where people get all bent out of shape over "defects" that can only be seen on a computer monitor with the image blown up many times bigger than you could ever use to actually view a photograph. Those of us who are interested in making photographs refer to that as "pixel peeping." Sounds like pretty much the same thing.

5D MkII with the original firmware that had those black dots?

**meyerweb** · 03-18-2013, 12:29 PM

Ah, a fellow photographer!

Do you mean, like dark splotches? I've experienced this while using Screen Filter to get brightness levels very very low for reading in the dark, and I do notice slightly darker black splotches that are not single pixels but are fairly small still. Are you getting this with normal brightness settings, like with just the system settings? I figured it was just my Screen Filter app. I don't notice it without using that app. I don't notice it with minimum brightness normal system settings.

I think this occurs because of the nature of the OLED screen. Since they are all individual, small fluctuations can cause slight imbalances at these lower-than-normal levels. I personally don't care a bit. I just was worried at first that I had a defective screen that would soon go bad on me or something. The screen is still totally fine to look at, and like I said, it's only at super low brightness levels. I wouldn't worry at all.

I also have an iPad and you should see the uproar that breaks out over "light bleed or leaking" every time a new iPad comes out. People claiming to return dozens of iPads just to get a perfect screen, often over something that is generally present on most LCD screens to some degree, and over something that except in extreme cases, you can only see in a dark room with a dark screen.
