[Q] Screen blackness

The Nexus S had a completely black screen - at night black was no different that if it was switched off. My GN appears to have slight screen glow in the backs. However, I thought they were both SAMOLED screens? Presume I am wrong? Can anyone explain?
/R

I noticed the same thing. I just assumed that not all sAMOLED screens are equal, and that the change in resolution could have been a cause. Maybe Samsung wasn't able to perfect it. Just speculation
It is pretty close though.

I was expecting this too and was a little dissapointed, was looking forward to having my night clock on and the only light coming from the screen to be the clock text but the whole screen has a slight glow to it

Same here, I wonder why is it like that. No bragging of true black anymore. Feels like step backwards.

The screen does do true black.
It's just the wallpaper isn't turned to black, it's made very dim.
The "slight glow" is the dim wallpaper if you look carefully.

Hmm, I made own 1x1 black picture for background. Still it isn't true black.

The same here, not nearly as black as my old Galaxy S

The blacks look black as black to me.

Mine seems pretty black. I've only had a Vibrant with SAMOLED before, and I think this is equivalent if not better. Sadly, I've got a small weird green dent on the pixels on the second quadrant though...

I've noticed this too. Definately not as dark as my Galaxy S2 was.

My blacks look as good as my GS2's did to my eye. When you guys open up the app drawer, it's not totally black behind the icons? I can't make out bezel or screen with blacks.

I've also noticed that the blacks aren't as black as on my Galaxy S. The blackness on the GS was even more noticeable since every colour displayed is eye-burstingly vivid. I do miss the true black but at least the general display is nicer on the GN than the GS.

I just used the night display mode on Gentle Alarm.
I put the Galaxy Nexus and Galaxy S2 side-by-side.
The Nexus definitely has a noticeable backlight compared to the S2.

Well the nexus doesn't use any backlight. Which is odd because there is a definite glow, I wonder if some screen tuning can remove it

Nigel Tufnel: It's like, how much more black could this be? and the answer is none. None more black.

I hate black screens I only like white ones....yea i said it!
My screen is as dark as midnight and is peferectly fine with me.

Can people please who say screen is completely black test the clock app in night mode in a perfectly dark place. I have a feeling this is not only in some of the phones but in all. Will contact support to verify this.

I think the black tint on the glass isn't as dark as it was on the nexus s. At least that's how it looks on my gnex.

When the screen is on for an AMOLED display, it's not "true black". If I remember correctly, there's a minimum voltage applied when the screen is on. Otherwise it would draw more power to switch the pixels from fully off to on. In other words, the GN might have some slightly different minimum voltage.

As mentioned earlier, the clock app doesn't use a pure black background. Rather, it uses an dark overlay over your wallpaper.
Also, the default background for apps has been changed to one that isn't pure black

screen blackness

someone here already mentioned that the GN screen isn't as black as the gs2 or nexus s. as in, a backlight is still visible on an all black background. can others confirm this? even better, can someone who owns both phones, or all 3, take a comparison pic? thanks

I have the Nexus and GSII side by side and there is no difference in the 'blackness' when the screens are switched off. AMOLED does not use a backlight; absolute black is represented by a switched off pixel.
One thing I have noticed is that in boot screen animation they use a grayish background rather than absolute black which is kind of stupid. Makes the screen look like a washed out LCD.

i should have been more clear. i was referring to the screen in a switched on position with lets say an all black wallpaper. i know how amoled screens use a switched off pixel for blacks but some people on these forums have claimed that they are noticing a slight backlight, especially visible in the dark

Galaxy nexus screen is pure black; however, it does seem to have more reflection when around light, and that light makes the pure blacks look not pure black.
But if you are in a dark area, blacks are pure black.

Mine is clearly glowing when having pure black background. Like night and day difference compared to my Nexus S which has pure black. I try to take comparison photo of the two as I'm about to send my GN for warranty.

myself noticed this although I'm not really concerned for now ( I own a nexus s )

So are the pixels 'off' or not..that is the question!
On the Battery test thread the all Black and all White screens were comparable in battery life, which i wouldn't expect.

No, they are not off.
AMOLED screens have a minimum voltage applied when on. To turn a OLED pixel from fully off to fully on takes a lot more power. The contrast ratio of the sAMOLED screen is something like 100,000:1.

I guess the minimum voltage in GN has been increased at least compared to Nexus S. Here's comparison of my Nexus S (left) and GN (right). Pic is taken with 5 sec exposure. To be honest, the difference in that photo looks slightly bigger compared to what it is real life, probably because of that exposure time.

aww that's kinda disappointing. I was really hoping for a pure black screen =/ you might be right about the minimum voltage increase being the cause of this

Well mine is BLACK and those pictures on my gn may look grey but the black around the phones show jet black (as viewed on my gn) Trust me blacks are black!

Disappointed, my Nexus S is really black.
Hope this is software issue and can be improved with future update.

you are correct the blackness is not pure black as my galaxy s, strange as it is using same screen technology

It is not pure black (as in a void of darkness) as it is like on my Nexus One. Very difficult to see... but seeable...

It is 100% a software issue. I've just done the same test using the same app (thanks for the link) and what I've noticed was the black wasn't pure black like Nexus S but software buttons were PURE BLACK. Because they are the part of the screen itself, it means Google changed it on purpose (or it's a bug)

Really hope this gets fixed

My screen is totally black when viewed when any light is around...like DAMN, black.
But I definitely agree when viewed in total blackness it looks like the screen has a (dim)backlight. Hopefully software and not hardware.

I think this could possible something that google have done on purpose to make the colours more "true to life" as with my S2 the blacks were gorgeous as the screen went off, but sometimes it didn't make the image very real as blacks were sometimes darker than they actually should of been
Any i don't know :/ - would be nice to have the option ie a switch on and off switch

Blacks are not completely black

Previous to my GN, I've had a Nexus One, Nexus S, and Galaxy S II (international version) and on all of the phones black levels were pitch black and no different to the screen being completely off. Despite still being an AMOLED display, it seems the GN's screen can't do pitch black.
As a test, go in a dark room and open the clock app. Long press anywhere on the screen and the clock will go into night mode where it will be a completely black screen with just the time showing. You'll notice that there is a still a bit of light emitting from the dark spots.
A little disappointing... I wonder if this could be fixed in software.

It can do pure black but not everything is pure black. I just rebooted and say the Google boot image. Its solid black. I'm in a dark room now and can't tell a difference where the soft keys end and the case begins.

Actually that's just the clock app, you can easily see that it's an extremely dimmed version of your wallpaper. My wallpaper is this http://cooldesktopbackgroundsx.com/wp-content/uploads/2011/02/34327523.png
and I can easily see the eye in the dark mode.

I don't see how your background could make a difference. Night mode is completely black. Just look at the screen shot.
I can also notice this when first booting up and see the Google logo. It was the same this on two other units that I looked at, so I don't think it's unique to my phone. To truly notice it you have to be in a pitch black room. I only noticed it because I was using my phone as a bed side clock.

The whole point of AMOLED is that each pixel is it's own light source which can be completely turned off. True black was possible on every AMOLED phone I've ever used prior to this one.

That is exactly correct. Fortunately, at very low brightness, my GN does indeed display true black. I have an all black background and if I cover the time, I can't tell a difference between the phone off and on. Keep in mind that true black only occurs under extremely low brightness. Turning the brightness up introduces a bit of light polution.

No, no... I've owned the Fascinate on Verizon and when in complete darkness you can see a little bit of light emitting from the screen. The Gnex just has more pixels so there's probably more light emitting. But the blacks don't seem to be any less black than my Fascinate. When you turn the screen on the pixels must be excited in order to know when they must turn on or off, this will still emit a miniscule amount light.

I'm sorry but you're TERRIBLY mistaken and I wish this thread would get deleted before you confuse others! Night mode is simply DIMMED. It is NOT 100% black, but transparently darkened. There is a really easy way you can see this for yourself, simply turn on an animated live wall paper and go into night mode in the clock. You'll se the moving live wallpaper in the background in the "black" areas. That screen shot you took is showing the TRANSPARENCY where it's black. It is NOT actually black there!!!
The GNEX screen is JUST as black as any other SAMOLED Screen if not even more so! If you want to see 100% black - just boot into clockwork mod recovery! the entire background ther is 100% black and you'll see how inky black it looks! That said the status bar at the top of the screen is also black, and blends right in with the bezel.

What are you smoking? Download that screen shot and check thd color yourself. Its #000000, meaning BLACK. The only confusion is with people not knowing how to go into that mode in the clock. LONG PRESS, not just a simple tap.

Managed to finally find another thread talking about this. Theres even photographic evidence using a long exposure shot.

I guess the comment that there is always a minimum amount of power in even the black pixels could be accurate.

Yes. From what I have read (OLED information, a few book selections, and an interesting patent) sAMOLED displays include what is called "pixel pre-charging".
This is due to the fact that it is far easier to precisely control the pixel, which corresponds to a "drive voltage", when the starting point is a pre-charge. Its faster and more accurate. However the pre-charge causes light to be emitted. There is no avoiding that. As much as people say "my nexus s/galaxy s/galaxy s 2 have pure black", there is NO SUCH THING even on a sAMOLED display. Contrast ratio for the Galaxy Nexus is 100,000:1 rather than infinite.

Hi, just wanted to put this topic to rest.
Was somewhat disappointed in the screen performance of the Galaxy Nexus, coming from an Galaxy S2. However I reckon it is an issue that can be fixed with drivers.
The blacks on the Galaxy Nexus are far from as good as the SAMOLED+ panel on the SGS2.
Here are some pictures of them side by side with the clock app set to night modus.
Not a deal breaker for me, but I hope this is improved in future updates.
PS: Sorry for the big-ass pictures..

my screen is blacker than the bezel..

What is your wallpaper, cause I think I can see it in the second to last photo. Like stated above, the clock is only a semi transparency over the wallpaper. Run a screen checker and take pictures of that black, that would be a better test and example
Edit: in all likely hood its just a calibration issue. Franco's kernel improved whites and colors significantly over stock. Personally, I can see that its not 100% black at the moment, but it is 99.999% black. And 100x better than backlit

The technology switches off the pixel so there is no blacker than that if you are not getting pure black then something is wrong most probably the wallpaper is not really black.

Pentile Display ?

it is said that the galaxy nexus uses the pentile display .. and all we know that pentile isn't really good .. so i am going to buy a nexus tonight and i would to ask you if the screen good or bad .. do you like it or not ?

I've had numerous phones, GS2, iPhone 4...this is the best screen I've seen yet.
The Pentile discussion is kind of ridiculous.

I've had four phones this year
- Vibrant
- My touch
- Nexus S
- Evo 3d
When compared to everything else including my friends' iPhone this is the best display I have ever used.

Its crazy good, by far the best screen on any device I've ever seen, blacks are so black u can't tell where the phone ends and the screen begins without looking really close. Also u can load up pretty much any page in portrait view with far away zoom and STILL read the really really fine text just fine.

Yeah it uses a pentile display much to people's dismay. Quite a few people/reviews have stated the following: 1.) Whites appear like a linen yellow. 2.) Blue tinge on the screen 3.) Pixelation is noticeable on text. While that is all true the screen isn't that bad, passable at least while playing games or watching videos. Is it the BEST screen ever? I would say no.

Calm down there Nexus fan boy/girl! I'm just stating these are things people have seen. Obviously not saying the blue tinge along w/ the yellow whites occur at the same time. Yes I have seen the screen numerous times, and a co-worker was the one to tell me about the yellowish whites.

Pentile on the original SGS/NexusS wasn't nearly what it is on this Galaxy Nexus. Last night I spent about an hour comparing and contrasting between his iPhone4s and my brand new Galaxy Nexus. When it came down to it, the Galaxy Nexus had the same readability as the vaunted Retina display, but with deeper blacks, and generally more vibrant (ermm, oversaturated) colors. Looks great to me, but people have different preferences.

i've had the moto droid, moto atrix, htc thunderbolt, iphone4, and this is by far the nicest screen ive ever had.

Are you just quoting other posts or do you actually have a GN? If so does the screen look yellow, blue, or pixelated to you? If it does I would return it ASAP because it shouldn't. Mine and the ones I've played with in the store do not.

Pentile? What Pentile?
In my experience, the pentile isn't an issue. The screen is (theoretically) gorgeous, however (and maybe I'm an exception), I've seen that only about 1 in 3 GNexi have a screen that truly looks like it's supposed to. I'm on my third GNex, two of the three have had different screen issues, and the third had a great display but a blown earpiece
That being said, I wouldn't hesitate to buy one, just be sure to THOROUGHLY inspect it before you leave the store. I'm going back for my fourth today.

My co-workers device's screen white's looked yellow. I went into the store to mess around w/ the device and did notice the same on those units. There have been others stating there is a blue tinge, which is supposedly a normal thing, as to preserve the blue pixel. The screen has minor pixelation but it's not too noticeable like the Moto devices.

You must have microscope eyes then. I can't see any pixelation holding device from one palm far from my eyes.

I do have very good vision yes.

No pixelation that I can see, and I use a lot of different types of high res screens for work. I'm really not sure how anyone can say they see pixelation on such a high density display. Take a look at the 'unlock' circle on the lock screen. You have to look realllly hard to see the jagidness - and this is a circle drawn with square pixels
Colours are slightly over saturated which makes them pop more, however they are not technically accurate - if you care. Eg. look at a photograph from a SLR camera on the gn vs a high quality computer screen.
The only real issue I see is the artefacts (grey 'dirty' look of white backgrounds) on the 2 or 3 lowest brightness settings. This is slightly annoying because you need to leave auto brightness on to preserve battery. You can however use a custom rom to change the lowest limit of brightness.
Trust me, when you turn it on, you'll think the 'google' logo that comes up is actually a sticker on the screen, and when the startup animation starts you'll fall off your chair

I will say that I can notice some pixelization of text, primarily on colored text (reds, blues, purples, etc. are the worst offenders), although that's not to say it's terribly pixelated, but it is noticeable if you know what you're looking for. Certainly nothing to dismiss the phone for, but to say it's not visible is untrue.

i can see it's pentile (having had a nexus one I know how it looks) but it's not much of a problem, the resolution is high enough. Sure it would be nicer if it was RGB, but it's good enough for me, at least (and I hated my N1's screen)

I agree. Overall I like the display better than my iphone 4, but it does have flaws, and I think the sharpness of the apple retina is better. Still, the blacks are to die for, and I like a little more punch to my colors since I'm not going to be doing any color-sensitive work on a phone. Plus, the size on the GN is juuuuust right.
Though I have to disagree with the poster that said the opening animation looks incredible. I was actually severely disappointed that they chose such a low res animation to "showcase" the HD super amoled display. It should be in native res, but it obviously isn't. That said, it would probably slow down the boot process considerably if that were the case, so it's just fine the way it is.

PenTile, yes. Excellent quality, also yes.
Unless you are a photographer, the colours shouldn't matter that much to you - white is still pretty white, and black is very black, and everything inbetween is pretty damn good too.
Those complaining about pixelation on the screen...well, to be honest, I can see pixels on my PC monitor, and it's a fancy-shmancy 1080p 120Hz 3D monster. I can see pixels on a Retina display. Pixels are everywhere.
I CAN SEE THE PIXELS D:

Note 2 screen defect on pure black screen in darkness

On my Galaxy Note 2, if I display a pure black screen in a completely dark room, I can see that first of all, the "black" is not really black, but somewhat pinkish. And second of all, there are "really black" dots and lines across what is supposed to be "pure black" but is somewhat pinkish (like i said). Also, this effect, of having a darker line, can also been seen with say, dark blue on screen in a completely dark room.
This effect is not noticeable when white or other colours are on screen. I'm really sorry but I can't show you a picture of this because obviously a screenshot captures the digital signal and not the physical output and I don't have a good enough camera to take pictures of what I'm saying in complete darkness.
Is this a defect or just an unavoidable "feature" of Samung AMOLED screens?

you did not use the search function: i personally wrote a huge amount of posts regarding this, also in the note1 section!
search for "black blotches" or take a look at my posts. really lots of them are about this!
in short:
its manufacturing dependant and its luck of the draw to get a "good" screen!
samsung lives with this as not many customers complain(ed) about it, as most of them do not even notice it!

Mine is pure back at full brightness when seen in a dark room (no pinkish hue or any line that you mention). And Note 2 screen doesn't even have the infamous black clipping/crushing issue like its predecessors! Blue colour also good, no issues for me.
No, it is definitely not an AMOLED feature or drawback (never seen it on any other AMOLEDs either)! Of all other aspects samsung SAMOLED screens are known to have the deepest blacks (with best contrast ratio). Sure, it sounds like you have a defective screen, and my suggestion would be to get it checked up at SC for replacement.

i also have a similar issue on my note 2. a black screen is not completely black, but a brownish black. And i can see 3 (or more) dots which are completely black.. i can see this only in a dark room, so normally this is not an issue. But when i read kindle in my bed with dark background, this really bothers me. initially i thought this was some smudge on the screen. im sad to hear that other people are also having this issue..

I had the black dots on my galaxy s2 ... but not my note ... The screen on my note has none of that sooooooo happy about that it really is just luck of the draw ....

Same issue here. But it does not bother me that much, and if I get it replaced, the next one might have worse issues.

im only worried if it will grow in time. like a dead pixel in an LCD screen, if this phenomenon spreads to the neighboring pixels over time, then its a very bad thing... otherwise, i am not bothered at all..

We need this thread each time there is a new phone which amoled screen? ..
The sgs2 has this as well as the sgs3 the note 1 etc.
it's not a defect, it's a limitation of amoled screen production.

Sorry, what you say here its not possible! EVERY amoled 'suffers' from this ('cause it CANNOT display 100% blacks, due to it's active matrix)! If you won't see it it's because of a wrong method or your eyes!
