I posted this on the galaxy s forums too, but it seems a little dead there.
As seen by the NoLED app over in the (galaxy S) dev section, and in a few other places on the net, people are finding that when they display a black image on their amoled/samoled screens in a dark room there is still light emitted by the display. it is not truly black
I would like to know why!
One thing i hear is about image compression and signal noise causing the pixels to not display #000000 black and instead a variant of black/grey causing the pixel to become lit.
This problem is not an issue during the day, i can't tell the difference when my screen is displaying black or off. but what it does effect is battery life.
If the screen isn't powering down its pixels then it is not saving anywhere near as much power as it could do
Were we cheated of our true black?
My phone has the AMOLED. I did notice that I can see the backlight through a black screen, usually during boot up. It dosent really bother me. I didnt feel cheated or anything like that. The images look fine.
My phone could use better battery management, my MT3g battery spoiled me.
The odd thing is that there is no backlight on OLED displays - the light is produced by each individual pixel. It ought to produce true black as the pixels should be entirely off, producing no light at all.
The problem with your analysis is that your using a third party app to test this,
what if the code is messing with the display ????
best way to test this is to upload a black image onto your phone and keep it on for a few hours , now check if the display is consuming battery in the battery usage screen, report your findings here ?
Btw normal AMOLEDS differ from S-AMOLED , they don't have true black so they need to turn on the pixels in the display to display blacks.
They should be the same actually, same technology powering the pixels, same lack of a backlight.
I did my testing on the galaxy S with its super amoled, showing a true black bmp image and the screen is still lit.
There shouldn't be any reason to turn on pixels to display black - black is the absence of light, so creating light to display black is rather counterintuitive.
Pure blacks can't be expected from an LCD because the pixels have to block the light from the always-on backlight, but they ought to be achievable (as far as ambient lighting conditions permit) from an OLED.
I do wonder if this is something PenTile-related, but considering that's a technology designed for OLEDs, you'd hope not!
The PenTile display, iirc correctly, has a white subpixel. Maybe thats where the light is coming from?
ooo .... ooo .... ooo .... does that mean by default no more BLACK screen of death??
On a serious note, i'd find it odd that a program can screw up showing a black screen. Wasn't it usualy a case of (well in my day anyway!) poking #000000 to the "pixels" address? (or however many 0's you need for a true 16bit display)
it cant be because its a RGBW display because each led can still be turned off. there still is no backlight.
Also i doubt its RGBW, most likely RGBG

Yeah, pretty sure it's RGBG. RGBW is a different PenTile layout.

My life is my phone, and the next StarTrek convention isnt until August 13th in Nj, so until then well debate about screen pixels and how black is black on an AMOLED.
Are you guys using true black? In CMKY terms true black is not 100 100 100 100, or RGB terms 0 0 0. That means 100% color of each of the 3/4 colors. In the printing industry if someone chooses black like this from the color pattern it comes out as greyish black in print.
Heres a good artcle that should help you guys make a true black image in photoshop.

Hopefully after reading this you will find that the tests people are using and the color black are very volatile. First make a true black image, then test from there.

A black is easily achieved in assembler (and i'm assuming therefore in C) by simply setting the pixels on the bitmap to 00,00,00 (maybe a few more zero's for more colour range?). This is the "true" black of a device.
i used photoshop to get a high quality uncompressed RGB 0 0 0 bmp image.
the screen is still lit

I'm wondering if thats the best way to test it. If your viewing your image you created in PS it could be rendering it into colors like 1,0,0 , or 0,0,1, etc.... I would imagine you would need to write a program that actually sets each pixal at 0,0,0.
Problem
The display on my s3 mini is not showing true black but a feint gray shade and it has few curved lines that are COMPLETELY BLACK...I'm wondering if I can make the whole display black as there is nothing wrong with the screen...I was unable to capture this on camera as it was too dark
I'm kind of late to the party but...
I saw that problem on my Samsung Galaxy Express (similar to S3) but I moved away from Samsung for a few generations. Now on my A52 I saw the same "problem".
Turns out it's the eye confort shield that turns the screen dimmer and yellowish, it was messing with the true blacks. I disabled it and couldn't see anything at all it was pitch black.
Not sure if that was the problem with my old Galaxy device... But it makes sense that when you notice it the most, is when that eye protection is active.
Hope this helps anyone
I just want to know if you satisfied with the One S pentile matrix screen. I have a Sam S2 and recently bought a One S (S3 chipset) and i noticed the lcd is very pixelated (if its a real word, sry for my English) compared with the S2's screen. Its not too bad but noticeable and a bit disappointing. How you live with this?

By not being incredibly picky. The phone wasn't cheap, so before I signed a contract, I made sure I was happy with every aspect of the phone. While I do agree it's pixelated, and that my Sensation had slightly better quality, I am incredibly happy with the screen. I'm rarely centimeters away from the screen so I can live with it especially because the color reproduction is amazing.

I think you just get used to it after a while. I couldn't stand the screen when I first got the phone, It stopped me using it regularly because I just used to get annoyed at the screen! (sad I know) But now I don't even think about the screen because I'm so used to it. I came from the Desire S which had a S-LCD display and a 480x800 display so that was a very good screen considering it was only 3.7 inches! I found the amoled colours of the one s to be extremely saturated. I didn't like the yellowish/blueish whites and the fact that every time you slightly changed the angle of the screen the colours would turn slightly blue. Text looked pixelated especially on a white background, that doesn't help considering a key part of sense 4 settings is all white background. It took me a good month to get used to the screen and 3 months in, I'm used to it Possibly getting the Nexus 4 soon so doubt I'll have much longer with this phone anyway.
Sorry for the little off topic might pickup a one s didn't want to start a new thread...
I saw the one s at my local fido store and damn its so snappy even whit sense !! But i tried the one x and it was somewhat slower is this normal ? Flicking through homescreens just werent the same..

I did notice it some when I first got it, but I really don't anymore at all, and like was said above, I'm never close enough to my display to really notice it. I think the screen is incredible, as is every other aspect of the phone. I LOVE my One S.
I thought it would annoy me, but the phone was free so I decided to bite the bullet. I've had the phone 6 months now, and I really don't notice it at this point.
I love the one S display, sure the screen isn't as sharp as the GN, GS 3 and one X etc. and you don't get as much screen real estate but everything else is just as good, if not better:
- one of the best screens in sun light, don't even have to put my screen above 70% brightness in direct sun light in order to be able to make stuff out easily and this is on a darkish background too, MUCH better than the GN and GS 2 in this area
- colour reproduction is superb, my screen is pretty much perfect, whites are super white, brighter white than my dell u2311h, iirc a review site stated that the screen is better calibrated than the GS 3 SAMOLED screen
- no tinting at all on mine, usually with AMOLED screens you get a blue or yellow tint, which is noticeable at angles on whites but not on mine (this varies with every single screen though)
- of course blacks are black and the viewing angles are superb
- high contrast ratio etc. so games and videos look great
I only notice the pentile when looking at white text on black backgrounds and a few icons, but only when I really look for it and have my face pretty close to the screen. I find the one S screen to be sharper overall compared to the GS 2 screen.
I have had the one S beside the GS 2, GN and GS 3 and personally I didn't like the GS 2 screen at all, res. is too low so things are huge (felt like an old man using a phone designed for people with poor eye sight ), colours are far too saturated/warm. The GN screen is nice and sharp but the colours aren't saturated enough, rather dull over all and plus both phones are poor in comparison to the S for view ability in the sunshine. The GS 3 screen is great, better than the GN, however, I think the one S screen looks better for colours.
Anandtech more or less summed up my thoughts:
What’s different, however, is how well HTC has controlled the color temperature and gamma compared to Motorola in the RAZR. As shown in the HCFR galleries below, gamma is pretty close to 2.2 until you get to the high end, and color temperature is pretty close to 6500K, except at the two darkest grey points. This is so much better than any other OEM calibration of an AMOLED panel I’ve taken a look at, which is rather humorous because the panel is undoubtably Samsung’s. HTC is also letting the panel go pretty bright, up past 350 nits, instead of clamping it way down around 200 (I’m looking at you, Galaxy Nexus) to save power. I also haven’t noticed blacks not being totally off on the One S like I have with some others. Of course, colors are still massively oversaturated if your source color space is sRGB.
I’ve griped about PenTile RGBG before on this panel and other SAMOLED displays, but I find the One S to be completely enjoyable in spite of having it thanks to two things. First, how well HTC has controlled the panel (no awful hues, weird white points, or dramatic shifts as you change brightness) - this is basically the best I’ve seen this particular panel, and until SGS3, the best I’ve seen AMOLED in general. Second, because HTC doesn’t appear to be applying any processing that applies sharpening (like Samsung’s mDNIe) to text.
How you feel about PenTile really is the final factor: it’s there, but I’ve slowly become accustomed to it after staring at it for so long. If you go back to the Nexus S days, I was one of the most outspoken critics because of how large those subpixels were. With small enough subpixels (below visual acuity), PenTile starts to make sense. In other news, HTC moving back to Samsung AMOLED for phones is an interesting move after supply issues forced HTC to SLCD with some earlier phones, here on the HTC One S however, it looks great.

My solution: Get old. You probably can't see all the minute issues you guys think matter, and you don't really care if you do. Every phone I've ever had has had a better screen than the previous and I think that's pretty nice.
I hate the screen, drives me nuts. I found that using a theme that mostly uses blacks and whites makes it more bearable though.

Have to agree. Thing is apart from the screen it's a fantastic phone. It's so fast, battery life is great and the camera is great. I don't even think the screen would be that bad if it wasn't pentile it's just the fact that it's a pentile display it makes the phone look way more pixelated than it should be
I think I need to go to specsavers, I've never noticed a problem with the screen.
The screen on this is amazing. Don't notice any pixellation whilst on it . It's quite an improvement over my old Wildfires QVGA 3.5 inch 240x320 TFT display.
Sent from my HTC One S using Tapatalk 2
If you switched from Wildfire you cant see this but if you had any phone in the alike pixel density and resolution you can see the difference. According to others opinion its not bad, the perfect color saturation, contrast etc will eliminate the bad feeling about those subpixels.
HTC does calibrate their screens nicely
I suppose it depends on what you're used to. When you come from an iPhone or high-end LCD-screen you probably will get annoyed with this display. However, when this is your first touchscreen smartphone or when you had a smartphone with a low-end display before this one, you will probably be able to cope with the slight pixilation.
Personally, even with this being my first touchscreen smartphone and coming from an E72 with a PPI of about 170, the display of this device would be the only reason for me to buy a One X or Nexus 4. That being said; you don't buy a smartphone solely for its display, you buy it for the complete package (price, battery, design, display, size, cpu/gpu, storage, support, OS, cloud integration etc.). And for me, the package the One S offers is more compelling than that of most other smartphones one the market.
I compared the One S screen to that of my Galaxy Nexus and honestly, when it comes to clarity, there isn't much of a difference. If you are in your twenties with near perfect eyesight and able to hold the phone less than a foot from your face then you will probably see pixelation but at normal distances it isn't an issue. For me it seems that anything above 250ppi is fine - my original Galaxy S was less (I think 233ppi) and that display was pixelated to me, but then again it was an earlier generation screen, I'm sure there have been other refinements besides resolution since then.
One S 256 PPI
Sam Galaxy S2 217 PPI but looks sharper.
Its all about the pixel placement, pentile matrix is a pattern. This matrix gives us better colors because more subpixels. Google for it there are many info i cant explain it in english
I come from an LG Optimus 2x, 4'' ips display, 800x480, and I feel this display better IMHO.

I said Galaxy S, not S2.
Yes the S2 was/is superior despite the lower resolution thanks to the RGB arrangement (not pentile). The original Galaxy S was pentile, and not that great by today's standards.
It's okay, but I'm actually kind of unsatisfied with the blacks. I thought it would be completely black, but when I have a black picture shown on the phone in a completely dark room, the screen still lights up

hi,
i just started this thread to get your opinions regarding the display quality of the note3!
i have to admit upfront that i'm a hypocrite when it comes to amoled screens, so far i had to switch all of my amoled devices a least 5 times until i got a unit which satisfied me. done this with the first note, and also with the second.
as far as i can say the screen of the note3 is the best i've ever seen (by far better black-levels as note1 and note2), although i also identified a few flaws as well:
the color RED has very bad viewing angles: when tilting the device a little bit the color gets orange immediately.
try this by enter *#0*# in the dialer, and click on "red" then tilt the device. let us know how "your red" is, thx!
the gamma of the screen is totally screwed: can see down to "1" in gammatest.png:
the disadvantage of this is that you are actually able to see dark grey screens which you should not.
on the left side of the screen border there is a small strip which has also more gamma then the rest of the screen, in menus etc.
this is clearly visible when its dark around. also only visible when at least a little grey is to display, pure black is ok!
this week i will test one or two more note3's, just to have a comparison and to determine if the quality spread is as big as with previous devices. for note1 and note2 the differences between devices were really huge. some screens were near to perfect, most of them had flaws with color unevenness.
what are your impressions?
and: do you care?
regards,
markus
edit 03.10.2013:
just got my second note (this time from amazon.de): the screen is considerably better!! the "more gamma" strip on the left side is non existent on the second device, in gammatest.png the screen is much more uniform! also the red viewing angle is better, it still fades to orange when tilted, but not as much as with my first device!
conclusio: the big differences in screen quality are still existant, it's still luck of the draw if you get a decent one or not...
also the general build quality differs: on the second device the pcb is not exactly in the middle of the casing, the camera hole is not centered in it's protrusion, and the power button extends a little more out of the casing.
again, i may be a "little" freaky about this things, but for > €700 I want to have a decent device!
screen quality is very important for me, because i read a lot with the device, especially in dark environments where the left gamma strip i mentioned was really annoying! i also showed this to a few colleagues of mine, and they agreed.
edit 04.10.2013:
another finding: when CPU load is high, the brightness jumps between a lower (darker) and a higher (brighter) state, even if brightness is set to manual: both devices show this behavior, although not exactly identically: my first device needs more load to start with this (it takes longer), the second one starts the dimming relatively early.
how to test: load a stress test tool (cpu prime benchmark from google play) and let it run, set the brightness to manual maximum and wait.
you will see that after a few seconds the screen will go darker, and will switch between this states. this is independent from the brightness level, it is only better seen at maximum!
i guess this is some power and/or thermal limitation (when more cores are under heavy load), it would be interesting how this kicks in in summer when ambient temperatures are higher...
edit 25.10.2013:
just to let you know: i'm now through 6 devices, all of them had display flaws in terms of uneveness.
a issue most of the devices suffer is the lower dark half of the screen: on 4 of my 6 note3's the lower half of the screen has been signifcantly darker then t´he upper half,
one had a very bad gamme increase on the left 2mm, one had a bad gamma increase on the top 2cm. 4 had a warmer white, two of them were more cold (more blue). could be due to missing or wrong factory calibration...
what is gone is the "blotch issue" i had with sgs2, note1 and note2, and: black is now really black!
but on dark grey levels the uneveness is clearly visible, look at the attached "gammatest.png"
this shows the lowest grey tones. and should be a very visible gradient from top to bottom.
go in a totally dark room, open the pic, zoom in max, and navigate to the top left corner. then pull the
picture down, and look how the numbers fade. for example: "6" should be at the same brightness level on top
and bottom of the screen. it definitely is not...
go out and test for yourself, and post your findings!

OLED screens are the only ones I know of that can get true black. With OLED the pixels make there own light so no back light is needed, thus black pixels are not being used at all so a black image has a nice inky black color. You notice it the best when you have a colorful picture with black in it.

sorry, but this is a wrong statement. all amoled screens so far were NOT totally black, even if you displayed a totally black image! the reason is that if the screen is active the display controller is powered (which is the case when displaying a black image, and not if the screen is "off") which can be seen as a faint and VERY dark glow. you can only see this when the room in which you are is totally dark, and your eyes had time to accommodate. to make it worse: on all AMOLED devices i've seen so far there were patterns (like hair lines and blotches) in this grey glow, due to the manufacturing technique used (lithography).
see for reference:

so the question of cd993 is reasonable!
answer: note3 is the first device where i cannot see this dark glow, even in a total dark room! so a big improvement on this side. not sure what they changed, but the glow is definitely gone!
Red turns orange here to, but it doesent bother me as the screen is nice overall. Much better than my note 2
Red turns orange when screen is tilted, yes. Black are true blacks in Note 3. If you go to a pitch black room, and display a completely black screen in Note3, the phone will blend in and disappear.

Please make a quick guide of what to test and what to look for on a new note 3, in order to decide whether or not to return or warranty claim. Basically: On arrival, what would you check for, and what result would make you return it and get a replacement? How much of any issue would be ok for you to keep it..?
N3 screen : brighter and look better than Note 2 and S4 but still can not compare to the best IPS screen about white color

You'll do that with any Android phone whether LCD or AMOLED because their screens aren't individually calibrated (iPhone's are). So there's some degree of acceptable production tolerances that means all built won't be identical. So whatevery you went through before you'll go through again with the N3.
Oled = true black
LCD = true white

My only concern with AMOLED is the blotches that show on a grey screen in a dark environment like the first time I noticed it using Facebook. I had to replace my first Note II and even the second has some blotches but not quite as big and bad.
I've attached a grey background for your convenience to see if your AMOLED has blotches. You'll need to be in a dark environment like reading at night without the lights on (simulate by going into the bathroom and turning off the light).

Pointing out to OP that the leaking light on the Note 2 (and s3) is extremely reduced in the S4 and Note 3 - you should not compare the Note 3 with the Note 2 in that aspect.
Black wallpaper on n3 = better battery life then?
Other than seeing imperfections in impractical situations, is there anything about the display that is actually bad in normal use? I mean do you see whites on this phone and think, hmm that's more of an off-white or is it like so small in difference that you need a color spectrometer to prove that it's not "true" white?

I know what you mean. I had that on my note 2. Not so on my note 3. When I open black screen in a pitch black room, the phone becomes completely invisible as it blends in perfectly with the dark. And yes, I'm not exaggerating. It's the deepest black I've ever seen on any display, it's like the phone is actually turned off.

Strange thing.
Today I decied to compare the displays of my two Edges - one black bought right after launch, the second one white bought few days ago. Guess what? The display is not the same. There is difference in colors intensity (white one has more strong colors and the white is more clear, where the black one seems darker more dim, like used) Or at least it is my impression. I checked both in the maximum brightness and in basic mode.... So after all, not all Edges just differ cause of processor ? Anyone checked it as well ?
Here we have 2 edges- white & gold, and the displayed colors of the white s7e seem to be a little bit more pastel, but it is not a big different. However, under same displaysettings there are some differences.
Btw the white s7e has the Sony Camera sensor, the golden one has Samsungs sensor. Has nothing to do with the display, just wanted to say.
I think i know where is problem- i have damaged screen . Now i can clearly see that yhe edges of the screen have kind of red tint. Similar to tvs that have their screen burned but here is just one color red. So i guess i have two phones that gotta go under warranty. I will post photos tomorrow .
This is normal by nature of amoled or any other type of screens. They just differ by nature. However i agree your point. Newer s7 edge displays have better whites. I left my device for screen replacement and the new one have a brighter and whiter display compared to old one.

search for my amoled threads, I started quite a few during the last years. and I exchanged every galaxy device I bought a few times to get one with a decent screen!
if you place 10 devices side to side, every screen will be little different in regard to tint, uniformity,...
only about 15% are close to perfect, these are the ones cut out from the center of the display wafer during production!

No, I'm not trying to sell washing powder, just trying to understand an issue I've had now with two Pixel 2 devices, and one that I posted about on the colour saturation and accuracy thread on the Real Life Review boards previously.
My first Pixel 2 arrived in December and I was immediately underwhelmed with the colour balance on the display - regardless of configuration options. Whites were very yellow - not as bad as when the Night Light was on, but far from white. So I returned the device, and a new one arrived a few days later. My second Pixel 2 is undoubtedly much better than the first. Not only was the colour balance better, it was also noticeably sharper when compared side by side. However, it still has a definite yellow tint in the whites, and some images seem to show this more than others - for example, flesh tones in the otherwise superb photos (when viewed on the device) look odd.
It's most noticeable for me when I have a nearby monitor or screen to compare. Individually the phone does not look so bad, but the whites on my monitor, laptop, tablet and even old phones are significantly whiter. (I'm not helped by the fact that I work in front of a screen all day - so I'm rarely able to avoid the comparison.)
Hence the question - both my devices have had a distinct yellow tint in the whites. How about yours?
I'd really like to keep the phone - because pretty much everything else about it is great. However, it's not a cheap phone, and because of that I'm not sure I should be making such a compromise on the display.
Any feedback appreciated.
I went to Best Buy and looked at the Pixel 2 they had there, and it had a similar yellow tint to the one I had that I RMA'd, but I don't think the tint was as bad on the one at Best Buy as it was on the one I had.
To get a comparison I just loaded the Play Store app (white background) and compared to a sheet of laser printer paper I had on my desk (under fluorescent lighting in my office). I'd have say my whites were a bit colder (i.e. less yellow) than the paper appeared under these lighting conditions.
I tried changing colour mode, but that didn't seem to have a dramatic effect on the white point, though "saturated" looked a little different - I'm not sure whether I'd describe it as "warmer" (more yellow/less blue) or just having slightly more green, but there was a very small change in colour temperature in that mode. I use "natural" myself anyway.

Thanks for the feedback.... I'm using natural mode too - boosted, or saturated just make the whites more yellow for me. It's subtle - but noticeable.
I've also noticed yellowish whites comparing it to other screens. Even my old N6P had better whites. I don't know if it's a generalized issue we should worry about, or just stick with it.

It's just how these screens were tuned. They are much warmer than LCD screens and look yellow when u compare to basically any other display. It's a feature, not a bug. Stop comparing and you won't notice it ?

You're right of course, I need to stop comparing... I just got a bit paranoid after my original RMA'd device's screen was so poor. I think I'm going to stick with it.
