[INFO] miura! AMOLED blotches/lines ANSWER

Hey guys,
I have a Nokia N9 (which uses an SAMOLED display made by samsung), and there have been some users reporting blotches/lines on their screens when in a pitch black room. I found this forum whilst conducting some research, and signed up after finally discovering what the problem actually is
It seems to be with the technology Samsung is using. According to this website, what you are experiencing is called 'mura'.... lines/spots as a result of an uneven current distribution to the OLEDs.....
Unfortunately as i am a new member, i can't post a link to the website.... but essentially, this company offers a technology that makes sure the mura never appear..... If only Samsung used it!!!!
AMOLED displays have two main layers:
An OLED (organic light-emitting diode) layer that emits light.
A backplane, made of TFT (thin-film transistor) circuits that provide current to the OLEDs, thereby controlling their brightness.
Polysilicon backplanes don’t provide uniform current because of manufacturing non-uniformities. Without IGNIS technology, the TFT circuits will provide different current to the OLEDs, which results in lines, spots, and cloudy areas known as “mura”.
IGNIS AdMo-p™ technology uses a patented TFT pixel circuit and driving scheme to compensate for the non-uniform backplane. So the TFT circuits always provide uniform current to the OLEDs, even though the TFTs themselves aren’t uniform. This means the AMOLED display will always show smooth, mura-free images.
Hopefully this gives everyone a bit of closure; I guess it's a case of finding a phone that has the mura to a lesser extent!

Appears for galaxy nexus too. Adjust brightness fix it sonewhat

Thanks for the insight !

Thanks for the very solid answer.

Appreciate the insight....however it doesn't explain why my vibrant and galaxy a 4G never had this problem....

What he is saying is that the lines and blotches are a manufacture/design issue in the displays of the SGS 2 and apparently the Galaxy Nexus as well. Being that SAMOLED screens are that drastically different from the ALOMED screens on the Vibrant and Galaxy 4G.
To bad Samsung didn't do better testing before making the SAMOLED screens our they would have sorted this out before the phones hit the shelves.

I thought the vibrant had super amoled and the galaxy s 2 has the super amoled plus? If that is the case then they should both use the same basic design?
Btw I think this is the link the OP is talking about

No, because these screens may have been produced by different manufacturers.
I'm just sayin!

Op needs to stop spamming for that company this is the second thread he's created with the same exact post

Well since this is a hardware issue like the vibrant's GPS, it is imho more tolerable. I won't be reading the forums in the dark anyways.
For those who want to read in the dark, hopefully a Dev out there can work some magic and get us a software work around, if that is even possible.

Dude.... Not saying the info isn't needed but does he really have to open new threads in the same section with the same post every 3hrs? So y don't you go suck a toe and see that he's advertising for the company saying that Samsung should have used them if they didn't want the issue...

I agree it shouldn't be posted in the same section just a few hours apart, not sure what happened there, but the info is helpful.
And what's wrong with advertising for this company? I doubt he works for them and even if he did, who cares? We all advertise for Samsung with every post we make that has a sig saying what phone we use. This is a pretty uniform issue across the board for devices using SAMOLED i.e. Nokia, Samsung, Motorola. If this company has a way to fix it, these companies should utilize their tech.

Thanks for the insight! Very helpful.

I went to edit my post but then something went wrong, hence the duplicate post (which i was unaware of)
I have no interest in that company whatsoever, i just thought I'd share that information with you seeing as no one else had come across it

Muahahahahahahaha.....fawking hilarity, thank you for the giggles.
To the |OP| thanks for the super pertinent info.

So if this is a hardware issue...is there anything Supercurio can really do about it (as I know a bunch of users are pitching in to get him a device)? Not trying to start something, I'm just curious

I don't know of he can do anything about it but he has done some spectacular stuff for the vibrant.
The vibrant was hardware and software deficient for the GPS but some devs out there got it working like a champ with some software miss and also if you were willing to take a risk and either bend a few delicate contacts or do some soldering on your phone's mobo.
So can he fix it? We'll see, quite possible I think

I guess I just don't understand how a poorly manufactured physical screen can be adjusted with a software patch, if the screen itself is faulty how can adjusting the graphics rendering put a band aid on an actual physical fault?

its been like over 3 months lol =/ soo sad, especially since it was supercurio, i trusted the guy =/

It has nothing to do with trust. He clearly stated his agenda and never gave a timeframe. He even stated a few times he was working on the note abd other phones first since they were easier fixes than our "black sheep" of a phone. He is well know and i wouldnt think that hed take a phone just to take it and not evetually work on it.

The blobs that everyone donated for was clearly a possible hardware issue which means that nobody would be able to fix it without mods made by hand. At best all he could do was look into it. Its not his fault people paid for a new phone just to look into it.
The whole situation is analogous to if Samsung released a new phone where a quarter of them had bad search buttons. It could be a software issue but likely a hardware problem with QA. Instead of exchanging the phone people then proceeded to setup a bounty to buy a new phone to get this fixed. Its looked into and it turns out its just a bad solder connecting the search button. This would of been likely in the first place and people should of just exchanged their phone rather than setting up a bounty for something which has a fair likelihood of being a hardware issue.
You have a hardware issue then exchange your phone.
If the blobs bother you exchange your phone. If the blobs only bother you when you have to follow a page of instructions on how to see it, really. If you need to follow a multi step guide to see it then its not that big of a deal. If it is then exchange your phone.

Just curious...
Anyone play the game Osmos....that will really show off your lines and blobs if you play it in a low light enviornment or at night.

I play it I notice it with auto brightness on mines so it doesn't bother me. Since my lines are not visible with auto brightness off. It doesn't bother me. Auto brightness is buggy on this phone. Anyway doesn't seem to accurate.

Yeaaa I turned brightness all the way up and it is much better of course but it is just unfortunate that this bandaid is the end all solution. The battery when playing a game and having the brightness all the way up gets effed.

I don't have to do that when auto brightness is on for me I have lines. When it's off at the lowest brightness no lines. If I can't see in the sun I just slide my fingers across the status bar to adjust.

Hmmm is it safe to say that the supercurio project for the t989 is dead???

Should I return it?

Just got my note 2 & noticed a small discoloration in the volume button as shown in the picture.
Everything is working perfectly
Is it worth the return?

If it doesn't really require lots of hassle, i would ask for a swap.

If I bought it at a store, I would return it.

It will definitely go back first thing in the morning as I just found that the theft side of the screen is waaaay to unresponsive to the spen.
Thank you guys.

Holy crapola that sucks! I was gonna say (before I read all the way down) that I'm so anal with my stuff that I'd return it in a heartbeat. Now that I see the sensitivity issue I'd obviously return it like you did. Hopefully that doesn't ruin your opinion of the Note 2 though, because it's a truly awesome phone! I've had mine for a few weeks now and I don't know what I'd do without it anymore!

Well, I'm a huge fan of the note concept & I know that Samsung's quality control is very very good but sometimes you get a lemon & you have to deal with it.

I guess I'm just fortunate I never have these issues....how did you purchase in store. ...yet its later outside the store you notice something you SHOULD have noticed at time of purchase.............doesn't everyone inspect their device prior to paying and leaving. As far as the s-pen issues people should adjust their settings mines works just fine you have to tweak the sensitivity to your own UNIQUE handwriting style

bipoler: Sometimes new gadget owners fall victim to the so-called Gollum syndrome: their eyes enlarge, their skintone dulls and greys out, and their cognitive functions are diminished. It can last from a few minutes to a few days, and only the worse failures can stop the symptoms quickly, more subtle defects take longer.

Well I got my unit online from timo's website. Once I got the device 18 hours later it was on its way back. The spen issue is not just a less sensitive area... its a deadzone which the device just does not register anything.

Not sure, received it that way from an inventory buyout. It was one of the few products that had been opened/returned? Didn't know if there was a common problem with somebody maybe trying to jailbreak and getting such a problem to occur?

If someone had root and a custom recovery and flashed a ROM but it wasn't a good ROM or a corrupt download or an improper ROM it can cause exactly that. Like I said look up ODIN, it'll set the phone to factory settings and you can be on your way to enjoy your s3

Dropped my phone, black screen (replace with D710 screen?)

Well I dropped my phone a few days and now all I have is a black screen. I figure I need a new digitizer and lcd screen but all the parts for the t989 are really expensive. So I was wondering if I could use the digitizer/lcd screen from the Sprint Galaxy S2 D710 since both our phones have the same sized screen, that way I could save myself a lot of money.
Hopefully someone can help me out I'm already tired of using a blackberry!

anyone?
