Do you know what is the origin of black spots on the screen?

I posted it a while back but because im using phone it just say it again. Its how the screen is. The panel problem. When they make an amoled screen. There is a TFT silicon backplate. Which is supposed to carry the current to the pixels turning them on and off etc... While creating the matrix a laser is used to change the silicon. Because the laser does not heat equally (middle heat different from outside of the laser heat) the crystals in the TFT dont form equally so an equal current does not pass to all pixels. The effect is called mura. Sadly it's a feature of amoled screens. The technology has not been perfected yet like LCD. Some have it worse and others don't.

I had this "pinkish stripes/lines in landscape" issue on my blue N9 ( several photos in this thread from other users). One day after purchase got new phone and same issue. My friend has white 64gb and no pink stripes. So sent today phone for repair, I guess they gonna change screen or something...

Edit: Picture from few pages back, I had this, my friend didn't have->

Wow, thanks for posting!

Can you tell me what capacity is your N9 (16/64Gb) and where is is made? And what about your friend's white N9?

My black 64Gb N9 Made in Finland has same stripes and also black spots in the dark. Don't know if I shall bother to try to get a replacement or all N9 AMOLEDs that way. :(

That pings stripes picture comes with trickery used by that blackandwhite squares, if same phone browses normal web pages there is no bleeding effect. Someone is screwing the system if they send device to nokia care because of abusing testing pattern picture that amoled screens doesnt like.

I didn't use myself that trickery, that picture is just for making clear point what I had without that pattern picture. Those stripes are most noticeable on that homepage/bookmark page in browser.

I had 16gb cyan and box says made in Finland. Not sure yet about my friend's.

Here's another picture of the same phone showing a "normal" webpage with the same pink stripes. (since when is it normal for a screen to be unable to display a simple checkerboard pattern...)

http://zerion7.pp.fi/n9/bleeding-2.png

The problem is even worse when you scroll a page, as the lines kind of shimmer.

Every N9 I've seen has this problem, although the intensity does vary some. As such, I've not taken mine for repair. (also I have no black spots, so I'm a little worried I might get a screen with that problem in return) Though all the N9s I've seen have been early made in Finland ones so perhaps the problem's been fixed in newer ones?

rainisto 2012-04-13 11:53

Re: Nokia N9 Screen Troubles (someone help me out confirm this)
 
ohwell apparantly you can get bleeding effect on some devices more easily than others. With testing pattern I can see bleeding in my too, but not in normal use. Of course if you see it on normal use and it irritates you too much then might be wise to try to get it replaced.

Well, not too cool: I have both black spots - most irritating in the GOF2 game - and I have AMOLED bleading - most annoying when typing SMS in portrait mode, the screen shows green, pink and dirty white stipes upwards of the on-screen keyboard.

ITs a feature of amoled.. AMOLED TECH is not ready yet eg, not too many companies are investing, sony cut back, and LG is focusing on large applications of oled for tvs and stuff, so that leaves samsung and Au-Optronics .there is not too much competition so, innovation is show.

Re: Nokia N9 Screen Troubles (someone help me out confirm this)
 
Just picked up my N9 this week. I'm using it as a stop gap till I decide on either WP8 or iPhone5 later in the year.

First impressions are positive, but my biggest problem is that screen! Next to my iPhone 4, websites looks awful. There's a weird discolouration to everything, most noticeable on predominantly white backgrounds. It's greenish tinge. The iPhone looks like a piece of crisp white paper. The N9 makes it look like a yellowed old newspaper! Even before I put the two side by side, I noticed the screen when web browsing wasn't reproducing colours accurately.

I have those too, but they are only evident during the startup video sequence. I am pretty sure you captured that during the startup sequence. Since it's a video, I don't expect it to be free from artifacts or blocky pixels.

whites, are a problem, But thats what you get when you have new technologies, Like Plasma,

Peoples don't forget try using your Amoled on low brightness, because it has burn-in when you have full brightness and displaying the same thing over and over

Some tips, Avoid using the same time format, every few weeks switch from AM/PM to 24 hrs because the M might burn in. and it will leave marks on your phone screen.

Get a short display timeout- OLEDS break up over time, the brighter the display the faster they bread down.

Avoid Deep blues, Or blues, the blues have the fastest breakdown rate. Greens are better and last the longest.

Try shifting your icons so they don't burn -In and leave marks on your screen.

there is an image from Gsmaerna showing Amoled v SLCD, real world close up

Kudos to you. I completely agree. Some people are just really making a big deal out of it. The average human eye won't even be able to tell the difference if it's pentile or not. The only people who keep complaining about it are the ones who hold their phones 5cm away from their eyes and claim to be display tech experts, and it's annoying that this has become a "problem" people can't get over about.

For the record, I am no expert when it comes to display technology, but ever since I got my N9, NOBODY (and I really mean NOBODY) has ever told me the N9 has an ugly screen. On the contrary, it has been all praises and "oohs and ahhhhs", and to think my friends all use iPhones and Galaxy S IIs. I don't necessarily brag about it, but to be honest, the N9's screen is definitely one of the best out there, especially when you factor in the phone's unparalleled design and construction.

Get over this pentile BS. Nothing you do will make the screen better, so instead of complaining or saying it's a "problem", get a new phone and ask yourself why did I buy an N9 in the first place? :p

Peace.

You mean like this... The actual Start Up sequence is Pixelated, Not sure why, if this was done by design. you must look to see it.

(Start-up screen has about 103 frames and a size of about 1.7 MB*)

dark spots will be visible on the multitask screen when nothing is open and you look at it on the darkroom.

Re: Nokia N9 Screen Troubles (someone help me out confirm this)
 
luckily, my n9 doesn't seem to have the black thingy :)

i set my n9's brightness to lowest, then tested camera app in a dark room, and even watched a movie with dark scenes, yet still, no black thingies were sited. yey. :D

i also dont have the purple and green lines unless of course the screen is like 5inches from my eyes...

i think they're normal since the screen of n9 is AMOLED... the pixels are arrange in a rgbg pattern.. and because of that, color display is not as vivid and as crisp compared to the lcd and superamoled+.. so it's normal that white will appear a bit dirty.

if your n9 has those black thingies, you can return them to nokia stores and they'll glady replace or repair it since it's a factory defect.

they're like the air blobs in the screen protectors, but only visible when it's dark. maybe they're the results of a faulty "gluing" method during the process of making the amoled screens.

Well, I've only seen three N9s besides my own, so it's possible I've just been unlucky too.

Re: Nokia N9 Screen Troubles (someone help me out confirm this)
 
my new n9 has the dark spots as well. did some research over at XDA and the lumia 900 has it worse, lots of samsungs have it, etc. mine are really small so its not a HUGE problem

Re: Nokia N9 Screen Troubles (someone help me out confirm this)
 
I don't know if anyone has put this forward yet, and if so i'm sorry.

But, i'm quite confident that those black things you are referring to, are air bubbles trapped between the leds and the glass.

ssjmec 2012-07-07 16:03

Re: Nokia N9 Screen Troubles (someone help me out confirm this)
 
So... In the messaging app, it is natural that my N9 is a bit yellowish instead of white?

I had a Lumia 800 (gave it back because I cannot do anything with it), it had exactly the same problems, only not that visible. Lumia-users most likely wouldn't notice unless they start looking for the stripes. So it's not even N9-specific.

Entirely different screen tech, still subjective as to whether it's "better", depends on use case.
There's been peeps who've weighed-in who own both, & it varies between them...

Yes, on low brightness. No, in screen is max bright. But in general this screen technology isn't notorious for accurate color reproduction.
As long as you don't have severe purple stripes you are fine. :)

Re: Nokia N9 Screen Troubles (someone help me out confirm this)
 
Do you know if I could ask a RMA for the screen on the right ?

http://data.imagup.com/12/1156528327.jpg
The one on the left, colours are fine, but the screen gets scratches, on the left screen doesn't seem to get scratches but is damm green at low light... :/

Hurrian 2012-07-28 08:37

Re: Nokia N9 Screen Troubles (someone help me out confirm this)
 
I've noticed the purple line on the left side, and purplish tint on the screen's top-left, while holding the N9 in portrait. Barely notice the green line at the right, though.

I think it can be avoided by some clever software tricks, if you swipe up an app and view it in the task switcher, the purple line's still there. Some research on this should be in order - the screen has absolutely fantastic blacks but pales in comparison to my N900's screen in almost every other category.

BTW, the issue is really noticeable in the low-power clock mode. It seemed like artifacting to me at first, but upon closer inspection, it looks like a problem arising from the way Pentile does colors (also, you can visually see the Pentile matrix, which slightly disturbs me when looking at bright pages)

Too bad it's a Pentile display without the high PPI that usually comes with it.

The one on the right is definitely way too bright. You should be able to get an RMA for it.

After awhile, I think we all just forgotten about the screen issue especially when Nokia showed lukewarm response to our queries, even the green tint issue raised by my original thread has gone "swept under the carpet" http://talk.maemo.org/showthread.php?t=81217 I guess we just had to live with it

I used a Nokia internal address, at the same time I guessed what his GMail address might be & cc'd it.
He got my email via his Nokia address, noticed that the Gmail address I used was wrong, & so he told me his correct GMail address.
From that point onwards I used his Nokia internal address & cc'd his (correct) GMail address...
