Display Artefact/ghosting line on lowest brightness

I have a diagonal line that runs along the width of the display it runs at a slight angel, it can be only seen with the display set a its lowest setting and running a black image in a very dark room. I have taken the phone back to three (solihull) who after 3 goes of trying to see it are aware of the problem and acknowledged it. They checked their demo phone which didn't have the problem. They have contacted their Samsung rep who I am awaiting a call from.
Does anyone have a similar problem?

This is normal with AMOLED displays.

the thing is, my GS2 doesnt have this "problem" on the lowest screen brightness.
I compared them last night side by side and its very noticable on my Nexus
That said, i've already accepted the fact that everyone else has some variation of this "issue" but im more curious on what the Samsung rep has to say about it. I'm also curious if its more visible on some devices as opposed to others.
I put my brightness on a static settings so it doenst effect me much (I can see it a bit on dark grey backgrounds) but i'm just imagining people who use auto brightness cause there's NO way you can miss it on whites/greys

you must have a magic Galaxy S II then, because it is a known issue with AMOLED screens when running at low brightness.

ill try and take a picture tonight with my devices side by side
honestly, anyone would be able to spot it out if you saw them in person.
Either my GS2 doesnt have the issue, or its VERY hard to see. I took long hard looks because i was really debating if my Nexus was defective - if this is just how it is then im willing to accept it - i just want to make sure we're not part of some funky batch

And if you said they tested the demo units, thats also my observation. Some screens have it more than others (others being almost not visible) and some inbetween

It may be a known issue, but that doesn't mean it's acceptable. I've not experienced any issues like this on either of my Fascinates. I'd certainly return mine if there were any screen issues.

I understand the artefacts you mean but this is a single bar about 3mm thick its not dead pixels like the three store suggested otherwise it wouldn't matter about the brightness it almost looks like something is pressing gently against the screen. I have tried to photograph it but my camera/me are not the best.

yeah its pretty much like that
it's like...grainy with weird colours. I wouldnt say i see any thick LINES, instead it reminds me of throwing paint on a wall and letting it slide down. I'll try and take a picture tonight with some high res camera so you guys can hopefully see what im talking about
unfortauntely its not so easy for me to get a return since im in canada and i bought mine through Handtec in the UK - im pretty sure RMA-ing is a huge hassle and wait, plus im not sure if i have to pay for the shipping

Its not like that on mine.

lol i took that pic with my G2x, its not as extreme as that in real life.

An OLED (organic light-emitting diode) is a light-emitting diode (LED) in which the emissive electroluminescent layer is a film of organic compounds which emit light in response to an electric current.
It;s Organic. Each row of organic pixels may have slightly different tolerances to voltage than the next, hence you get dark and lighter rows varying to different degrees on different screens.
By all means take a chance and see if a replacement is all the same tolerances with no darker or lighter lines or if it has lots of them and looks like a striped screen. I don't think its a "defect" as such, its just a "characteristic" of AMOLED. If they wanted Samsung could measure the tolerance of each OLED to a very accurate level and there would be no dark or light lines on any screen. It would be very expensive though, so they fall into a catagory of acceptable or not.
Thats just my opinion by the way.
edit: Im actual glad so many others are questioning this too. I feel less pedantic now. lol

Bear in mind that any replacement you get may in fact have a worse screen. I was lucky when I got my replacement phone (replaced due to volume bug, nothing to do with the screen) and my screen was luckily better. You may not be so lucky.

Indeed

well i just got my nexus today and as expected noticed a small transparant line running down with screen with auto brightness / low brightness. So i turned it of and manualy set to around 55 60% defintly cant notice it now just bummer cant use auto brightness .... will have to see how battery holds out like this as i luv this phone

Screen light blee.

Hi guys,
Do you have any light bleed on your screen? I have a few spots on the bottom edge of the screen.
Thank you,
Martin

Yea, That's Samsung for you. I was lucky not to have any on my device. And from the looks of it, it isn't too common on the Note 2014.
The Nexus 10 though. Wow. Everyone had it. It wasn't a question of if you have it or not, it was about how bad. Not to mention the blacks were blue.
I'd exchange it if I were you, no point in getting stuck with that.

Nope, no blee here.

I will exchange mine. Hopefully the new one will have no bleeD

Mine just came today and with my normal brightness setting there is only the slightest hint of bleed from one of the four LED spots on the bottom of the screen.
My panel seems perfect so far so it doesn't seem likely I will exchange it over this.
I'm pretty impressed, but I have to say the build quality is not up to par with my IPad and not what I would expect at this price. Samsung has a long way to go to produce really premium products.

I would like to see one iPad without a light bleed. So far a few I saw (including 2 which belong to my wife) had some light bleed as well. What is wrong with build quality of your unit? Mine, except for light bleed, is very good.

I think my tablet has very very slight bleed at the bottom of the screen near both capacitive buttons, I won't return it because it's barely noticeable BUT does this mean the whole screen has an issue and also could it deteriorate over more usage or anything like that.
Apologies if these are idiotic questions but this "screen bleed" is a completely new subject for me lol.

How was your exchanged tablet?

I think my light bleed is actually getting worse and I am thinking about exchanging it now that there is more stock available.
One of the spots on the bottom is about 1 cm, and while viewing movies it is a nuisance.
Does anyone have a perfect screen?

This was my worry, my screen has slight light bleed at the bottom nothing too noticeable but then again don't all LCD screens have some form of light bleed

Writting from my third Note 10.1 2014. The first one had a huge dust particle under the screen and bad bleeding. The second one had a bearable bleeding but at least 7 bad pixels (3 dead ones right in the middle of the screen and 4 stuck). This Note 10.1 has almost non- existent bleeding and just one little dust particle (invisible if you are not looking for it) but has yellow tint along the bottom edge (over the buttons) and at the bottom left corner, so when you are reading in portrait mode over white background it is impossible not to get distracted as you start one line with black over white and you finish it with black over yellow.
I truly love this device but I am getting tired of all of this. My third replacement is on its way, though I seriously doubt it is going to be a good one.
iiSo say we all!! from my SM- P600

Just noticed the blee today while watching netflix...does it actually get worse? I can live with it now but I would send it in for a replacement if it's gonna deteriorate over time

I'm on my third device and 2 of them have had lightbleed. I can't say for the first one though because the screen was dead on arrival. I think everyone should expect some lightbleed on any LCD screen. If your tablet is perfect in every other aspect other than a little screen bleeding then I wouldn't exchange it. There are too many things that can be messed up other than the screen such as S-pen detection, loose speaker grills, dead pixels, dead screens, faulty bluetooth, and the list goes on...

I have a 32bg black model and my GF has a white one, both bought at BB at about the same time. There is quite a lot of difference between the screens, mine has quite a bit of light bleed on the upper right and all across the bottom - you can see the individual leds - hers does not. However my screen is quite a bit brighter and much more "white," in side by side comparison hers looks a bit yellow. All of the screen settings are exactly the same. Last night we had them both on for 3+ hours of internet and point-and-click gaming, I had 80% power remaining while she had 56%, checking hers I noticed the brightness was at 100 while mine was around 25%. She says it needs to be that high to see the game and it does seem much darker/mudier than mine. Thinking these must have different panels because they look so different. So, light bleed or dim yellow battery eating screen, are these our options?

The pictures were taken with an iPhone 5S (flash off). The tablet's brightness was maxed and as you can see, the room was dark. Does this degree of backlight bleed warrant a return (mainly concerned of the tablet's longevity. Thoughts appreciated.

here it is. Same exact conditions. Thanks for your opinion, in advance.

The picture isnt very clear as its difficult to take a picture of properly but if the points I have highlighted are the only bit of screen light bleed you have then yeah its normal, I have pretty much identical bleed points too as do most people on here.

Thanks, I appreciate the prompt response.
And I'm inclined to agree with your observation. In particular, those are indeed the points of bleeding.
What do you make of the top corners being so bright, though? It's not like the points you've highlighted, but rather large areas -maybe this is where the light comes from?
In all honesty, I'm more concerned about future degradation than anything else. If the device is going to remain as is, I don't mind the current state of bleeding. But if this is an indication that the device will be noticeably worse in a few months down the road, then I'd like to take it back to the shop and exchange it.
Again, thanks for your time and opinion.
Much appreciated -and thanked.

No problem mate.
From what I understand Lightbleed comes from the points it's visable - it's just that for whatever reason the device doesn't block the light passing through hence the brighter areas along the bottom. And about degradation from what I have read it doesn't get worse or better just stays like that.
It depends on you if you want to give it back and keep trying to get a bleedless device but as some form of Lightbleed is common on LCD's it will be tough. I returned one due to high Lightbleed which was visable in a lit room and the brightness on low - that's bad Lightbleed and I couldn't accept that so I got the one I have now and the Lightbleed for me is more than acceptable. Plus the other problem is if your device is perfect apart from the bit of Lightbleed your next one could have other issues LOL.

IPS Screen/Backlight issue/bleed!

This being my first smartphone, I apologise if this question has been asked before and for generally being a noob, but hoping a recent answer would clarify the situation for me.
I know IPS screens for any type of device/product are prone to backlight bleeding, the reason I have a VA pc monitor. I did consider an amoled screen, but for the price, £300 and my intended uses, the G4 was the best option presently.
Without another phone to test it against and no photographic evidence for you guys my description is the best I can do. There are two points on the screen where I believe there is some bleeding present, but this is still subjective. The first is the along the top edge, where there is a very thin lighter strip of possible bleed, maybe an issue with the panel, where the info bar is normally present, that is lighter than then rest of the screen. I can notice it whilst watching full screen video, not always, when the bar is absent. The second is more minor, there are two spots on the bottom of the panel, either side and just above the LG logo where there is some bleed leakage, but minor.
I guess I'm asking is this common and worth the risk of replacing, or are the odds are I might get the same again?
Thanks.

Some light bleed top and bottom is going to be somewhat inevitable. On my phone it is noticeable if you look for it, but not too bad.
I have another issue with the panel itself not being uniform. The top of the panel (near the earpiece) is all bright and possibly on the touch of the yellow side of white. Lower down the screen towards the bottom left it goes towards pink.
Is yours OK in this regard? It is most noticeable with the phone in landscape reading forums like this.
I have a replacement phone arriving tomorrow to compare it to.

The uniformity on mine seems okay - using your suggested test on 50% brightness on this webpage, I have none of the other issues you mentioned (pink or yellowing), apart from that bright strip along the entire top edge under the front facing camera that is brighter and slightly washes out any colour/images on that edge.

Thanks. Another place it is noticeable on mine is in Gmail or any notification on the notification bar in landscape. Almost as if one side of the screen is a different colour to the other although you won't notice in photos or videos. Only on white/grey backgrounds.
It sounds like all you are seeing is the backlight bleeding through, this will happen to some extent on all LCD's. I tried screen test on the play store and on the black background test I can see a faint bar of greyish light right at the top of the screen. Unless you go AMOLED I think any replacement phone is going to look the same.

Hopefully a replacment will be an improvement for you.
I'll see a few days how this bleed works out for me. Would get an amoled, but the prices plus a lack of microsd card limit any options for me. Since testing lcd monitors, always try to avoid them now because of the panel issues that are inherent to this tech process.
Good luck on any replacment.

There's been a few good deals on the Galaxy S6 (around £325 unlocked) but all the reports of poor signal puts me off (and of course there's no micro SD). The G4 seems very strong in this regard, only phone I've ever had that works in a few of the blackspots round here (all other phones report no service) Some reviews even mention that it is a bit deaf.
AMOLED isn't without its own issues though.

It's not that obvious in real life, looks worse in the picture to be honest but I still can't live with it. It'll be going back when the replacement arrives tomorrow. Hopefully the replacement is fine otherwise I won't know what phone to get to replace it with. I can't get over how good the signal is now on it.

Replacement is way better. It's definitely a keeper. Has the slight 'light bleed' that you mentioned in your OP but the panel is at least completely uniform.

Screen issues

I've had 2 Oneplus 3's now, and am now in the process of sending the second unit back for a replacement.
This because the screen wasn't functioning properly, there was lightbleed on both and the screen had a green tint on one side and a red tint on the other side.
Has anyone else experienced issues like this? Is it a known problem, big or small? Or am I just in really bad luck by recieving a bad screen 2 times in a row.

No issue here. Wish the screen was brighter but at least its the same as my g4

The problems you're describing are physically impossible on a Super AMOLED display... and to say that it has happened to both OP3s you received is just as absurd. The pre-applied screen protector is pretty crappy, but I mean c'mon... Are you one of those guys who returns things with the smallest imperfections, or perceived imperfections in this case?

Do you have any picture of the defect. So far, your issue is uncommon one for OnePlus 3.

Woah there, I have no idea how it is possible to have the problems I have, I know that with lcd sometimes the glue causes the device to be lit unevenly, don't know if that could be the case, but it seemed a little off. I tested this using this video on full brightness: https://youtu.be/vu0mQa2EpS4
While going from. Grey to black, the pixels should all turn of at the same time, or at least, that's how I think it should be on amoled. But this wasn't the case on both devices.
As for the different tint problem, that does bother me a lot more, reading Web with a changing color if you read from left to right isn't that good for the eyes or at least It bothered me.

Here are some pictures, it's quite difficult to recreate on camera like I see them but this gives a general idea of what my issues were with the first device. The first being the screen tint, on the left of the screen it seems to be more red and on the right more green, while this is a Grey background at about 50% brightness. The second is how the screen is unevenly lit while on a solid Grey low brightness background.

I just watched that LCD test video and firstly my eyes hurt from the bright white light secondly I am quite picky and having come from the g4 which I thought had a great screen (few bleed issues though) I am quite happy. I couldn't see anything at all on my unit like you have so maybe it's device specific?
I have noticed this weird thing though and it's when I use MX player pro to watch films. I have been watching the dark night for like the 20th time on th op3 but do notice the skin tones look a little warm and when i increase brightness it gets worst. I think this is a combination of the pentile display and the AMOLED screen with a lower resolution than we would like. I am sure I remember my galaxy note 3 and wife's s5 looking like this also but could be wrong.
Overall it is strange using g4 then using op3 it's hard to explain but they are just different not just LCD / AMOLED but the calibration also. Love the blacks though it's like the phone is off when the screen goes dark. Nice.

So the screen turned black fully at the same time, well there's a logo on screen, but apart from that all black?
I know what you mean by that, I think thats in all screens, not sure, but I had it in both screens but also the problems occurred on them too, maybe that's a feature, I at least won't mind at night when the screen is that low and a bit more warm toned. I saw it on a selfie I got on whatsapp, at night when I got it, I saw her face normal, but when I set the screen brighter, I also saw that the photo also had a background! which was invisible and dark on the lowest brightness.

no issues

Didn't see a logo. Must be blind

Smallest imperfection? He uses the screen all the time and notices that all the time, how is that small imperfection? Also amoled screens are known for the issues he described. All screens have that issue. Just people like you are not good enough to notice it while others notice it easily.

Screen Problem

Hello, I've noticed that when I use my phone in night mode I can see green areas on the screen. Are there other people in my case?

No on mine so far. Black is black no greenish.

is see this too sometimes esp at night when its dark in the room with no other lights - in the day when its brighter is not visible
it does seem to be an issue with some backgrounds as i noticed in apps where the background is black (not dark grey or greysh) this isnt visible
so not sure whats going on - but i didnt had this issue with the s10 .....

Yes, I have the same problem, it comes from the screen according to what I read on some forums. Some OLED screen have problems. I think I'm going to get it exchanged.

no issues so far with mine s20+ (exynos variant), however if i were you i would seek to get replacement

slabs?

Screen sorry ^^

ok but how do you explain that its only visible sometimes and then sometimes is not?
and is only showing on grey backgrounds etc
like now i have the phone in my hand and is looking ok
the best place to test is in the samsung daily or SMS app - the top part of the app thats meant to be black was sometimes showing more like greyish - now is proper black again?
like i said it seems to be dependent on the ambient light - i wouldnt want to replace the phone if its not an actual issue esp since it took me a whole day to get my stuff transferred and setup

Oled is known for reduced quality the lower brightness you go.
But all units will have varied levels of tints etc

In my case..

Unfortunately, yes. Also, it is more noticeable at 120Hz.
There is a thread about that in the Ultra section:
https://forum.xda-developers.com/galaxy-s20-ultra/help/green-tint-dark-background-low-t4065621
I also tried to get people with that problem in the S20+ section:
https://forum.xda-developers.com/galaxy-s20-plus/help/s20-ultra-oled-bad-uniformity-bright-t4067051
It is rather horrible and i noticed it right away the first time I used it in the dark. I think it can not really be fixed in Software, but it can be probably made less noticeable, as 120Hz is making it worse.
I wrote an 'email to the CEO' about that here:
https://www.samsung.com/uk/info/cont...email-the-ceo/ (example: UK)

If its same as below thread...Welcome to OLED!
Colour blending (blacks) problem
https://forum.xda-developers.com/galaxy-s9-plus/help/colour-blending-blacks-problem-t3765385
Had this on my S9+ and S10. Nothing can be done about it.

Using OLED since 2010. Starting with Symbian Nokias, Windows Phone Nokias and switching over with the S8+ - OLED only.
I suppose - never had a display that bad in this regard. At least never noticed it that bad right away. The upper right corner is almost always showing a green tint.
But I am glad, if it is not too widespread - then the S20+ I ordered will probably be fine.

in your case what?

Pardon me?

sorry it was for an earlier post with a screenshot of a call in russian

Hi,
Just attached a picture of my screen with adaptive brightness with low light with screen at 120Hz.
At 60Hz the screen is even, at least almost even.
What is your opinion?
Thank you in advance.

Report it to Samsung, probably get it exchanged, if possible and it really bugs you.
I gave back the ultra because it was too much green tint. The plus has it as well, not as bad as the ultra.
