Thank you for taking the time to share this info. I'm going to give the Captivate a try as soon as it's released and won't spend time worrying too much about the screen now. :D

I was under the impression that this was happening on devices under normal use.
[Galaxy S I9000 Q&A, Help & Troubleshooting] drizek:
I don't know exactly how it works, but apparently using larger pixels helps.

[Galaxy S I9000 Q&A, Help & Troubleshooting] TravUK:
Thanks. Interesting article, and thankfully the Samsung screen is quite a bit more advanced from the Nexus One. As you say no explaination beyond the 'bigger pixel is better' comment.
[Galaxy S I9000 Q&A, Help & Troubleshooting] drizek:
Ya, I wouldn't buy a nexus one after reading that article.

Anyway, just watch this video and look at how much blacker and more saturated the SAMOLED display is compared to all the others, even the N1. Pretty amazing.
[Galaxy S I9000 Q&A, Help & Troubleshooting] El Mono:
I may be missing the point but I do not believe the PenTile pixel arrangement applies to the 4" super amoled display of the Galaxy S. I believe it relies on the traditional RGB arrangement as do most of Samsungs AMOLED. The do produce two "Visual WVGA" displays that utilize the PenTile arrangement (aka: Nexus One).

So far none of the devices I have with Samsung AMOLED's have suffered from burn-in. I did once have a phone with an AUOptronics AMOLED that suffered from some "ghosting."

Furthermore, I think the Super AMOLED name refers to the complete screen and capacitance sensor structure which contributes to a thinner, brighter... display. But what do I know?

No disrespect but that's impossible.. it must've been in the source video. OLED's have a response time of < .01ms from any color transition. Never seen anything but fluid/almost surreal motion on my Cowon S9.

edit - after actually using a captivate, I noticed the ghosting as well (scrolling through a website with black text on a white background).
[Galaxy S I9000 Q&A, Help & Troubleshooting] TravUK:
PenTile is a Samsung trademark, it is ONLY used on Samsung screens (which are in turn also used on non-Samsung phones). The human eye is more sensitive to green, which why displays tuned for human perception are green heavy, hence the RG/BG layout, in the same way that a 565 16bit display uses the extra bit for green. As discussed earlier in the thread and on the linked review, this layout improves the visual effects by accommodating aspects of the human visual model and combines them with efforts to increase the life of the blue organic dyes in the OLED elements.

You are partly right in that Super AMOLED does refer to the technologies of merging several of the layers that make up the top pane, the dyes, the lighting grid, and moving the placement of the sensor array, but that doesn't preclude it from being used with a PenTile matrix display.
[Galaxy S I9000 Q&A, Help & Troubleshooting] Spanga:
On my i7500 (AMOLED) I can see clear "watermarks" of the status bar when in fullscreen. I only used that phone about 6 months.
[Galaxy S I9000 Q&A, Help & Troubleshooting] Pops_G:
Night stand alarm clock? Some phones even have a night mode(HTC sense, and I am sure more then a few apps) where the background is black and the text is a light grey. That way you can always see what time it is at night without it being bright enough to disturb your sleep. With LCD this is an option, with AMOLED this could lead to burn in.
[Galaxy S I9000 Q&A, Help & Troubleshooting] El Mono:
No disrespect taken. I put ghosting in quotes because I wasn't sure how to describe it. Let me rephrase it by saying that that particular display would demonstrate a kind of burn in where images would remain visible for some time. I haven't noticed this with any of the AMOLED displays from Samsung (just my experience).

TravUK - I understand what PenTile is, and that Samsung owns the rights after essentially buying Clairvoyante (is it now Nouvoyance?). My only point is that not all Samsung AMOLED displays employ Pentile (subpixel arrangement, rendering, etc.). And if you go to Samsung's website that makes it quite clear which displays employ PenTile. Unfortunately, it doesn't mention their Super AMOLED displays. Who knows, maybe it is a PenTile display, maybe not. Like I said I could be wrong.

At the end of the day my point was just that I really like this display and have been impressed by it. Thanks,

El Mono
[Galaxy S I9000 Q&A, Help & Troubleshooting] TravUK:
I hope this clears it up, you can see from the zoomed section of the screen that it is an RG/BG PenTile layout.
[Galaxy S I9000 Q&A, Help & Troubleshooting] drizek:
Not if you have the traditional alarm clock color: red(for the same reason that it was the traditional color in the first place, and the same reason why nobody used blue LED backlighting until Apple came along and decided to be different).

Red lights last longer and use less energy. My Palm Pre even at lowest brightness is still bright enough to disturb my sleep with a black background, same with the iPad. The Galaxy will not have that problem since the black is actually black, and the reds can be dimmed . All you have to do to prevent wearing them out or burning them in is to just move the time around the screen a bit.
[Galaxy S I9000 Q&A, Help & Troubleshooting] El Mono:
Thanks TravUK. That is really quite fascinating.

I happen to like the richness of colors on these AMOLED displays. I noticed colors tended to be a bit more exaggerated on the screen of Nexus One, whereas the screen on the Galaxy S is bit more subdued. Not subdued overall, just subdued relative to the Nexus One's screen. Dare I say slightly better balanced. Problem is I've gotten used to looking at the Nexus One with the antiglare screen protector, whereas I decided to go uncovered with the Galaxy S - big difference obviously.

Regardless, I think it's a great screen

Thanks again,

El Mono
[Galaxy S I9000 Q&A, Help & Troubleshooting] alovell83:
@ OP, I guess your problem is resolved, but to have gone on and brought up the "boot screen" on more than one occasion as your logic, I just don't see what the big deal is. I look at the boot screen about 10% of the time it is booting on about 20% of boot ups, I imagine my viewing numbers will go down over time as well...the boot screen is so insignificant to the whole product, and I'd rather have a boot screen suffering from my notification bar than to have LCD on this phone because I simply love my SAMOLED.
[Galaxy S I9000 Q&A, Help & Troubleshooting] AshMa:
I have not seen the problem I asked about because I do not yet own an SGS. However the boot screen was mentioned by pocketnow.com and the logic behind it is simply because it's a screen that does not have the notification bar and remember it was the Nexus 1.........

There are way too many folks here on either side of the coin, so my questions (not just this thread, but all the issues being reported here), are only going to get answered after I purchase the device today at att or perhaps tomorrow from letstalk.com from which the Captivate will be free on contract. So I guess I'll find out........

Warning: Screen burn

Hi everyone,

I've had my sgs for 14days, keeping the screen on during the day to show time/music other things.

I now have fancy widget burnt into the screen when i have a white background shown.

Just letting everyone know about it so it doesn't happen to you.
[Galaxy S I9000 Q&A, Help & Troubleshooting] dragunov:
What?!? You mean that, whatever the screen displays, a part of the screen shows the same icon/widget?

Stupid question, but have you tried removing baterry and restarting?

[Galaxy S I9000 Q&A, Help & Troubleshooting] Pika007:
It's well known that AMOLED screens can get image retention, either temprary or permenant.

That's why you should always READ THE MANUAL

It's written there, black on white.

Now, countermeasures-

I don't know what condition your phone is in, but try doing the following:

1- create a 800X480 white jpeg (MAKE SURE IT'S 100% PURE WHITE)

load it to the phone, put the phone on 70% brightness, cancel sleep/screen turn off, and leave it for 5-6 hours.

2- After the white was, try a color wash. Get a video or something that changes RGB colors frequently.

This silly flash is the best thing in existance as a color wash:

http://dagobah.biz/flash/rgb.swf

(WARNING- PEOPLE WITH VISUALLY INDUCED EPILEPTIC SYNDROMES, DON'T OPEN THIS. I'M NOT KIDDING.)

Use it or someting similar (has to be fullscreen), leave it on loops for 2 hours.

I gaurentee that the situation will improve. If it's only image retention, the "burn" will disappear. If it's a screen burn in, it will reduce it's immensity.
[Galaxy S I9000 Q&A, Help & Troubleshooting] myrlar:
Thank you!

Lots of good suggestions... I will give them a go.

That is so cool, i'll use that for my default home screen, if it wasn't due the danger to random epileptical people that might catch a glimpse of that screen :p

after looking at it for 1/2 min, my optic nerves were like in overload :D ... probably that is what triggers the epilepsy on people with that disorder, it must be some sort of weak sensory stress level, and it actually causes an over load for them and send them into shock mode.

It definitely does get "screen burn" (technically image retention) I just exchanged mine and will be running Launcher Pro (since you can hide the notification bar) and keeping it at minimum brightness from day one, not to mention having it run an all white screen and flashing rgb patterns the first few weeks while I'm sleeping (like on a plasma) to be safe. If I get it again it's back to htc/lcd for me lol.

If you leave a static image on the screen full brightness and prevent the screen turning off, I don't see why not.. So, have you done that?
[Galaxy S I9000 Q&A, Help & Troubleshooting] Fatherboard:
Very worrying...

Create these images using photoshop of something, set each one of them to a resolution which matches the sgs (800x480), put all of them in one directory and use the gallery engine to run them as a slideshow. before running it, don't forget to set the screen to be always on.
[Galaxy S I9000 Q&A, Help & Troubleshooting] Srdjan1982:
There are static images(those symbols),brightness is at 70% and screen is set to turn off after 30 seconds.

I will try!

EDIT: Flashing didn't help!
[Galaxy S I9000 Q&A, Help & Troubleshooting] Laum:
Yep, there's definitely burn in especially in blue color! Also red is affected a bit. Green is fine.

Maybe showing full white screen over night might help.
[Galaxy S I9000 Q&A, Help & Troubleshooting] Srdjan1982:
That's right.It's not visible on green.

Should i try to return the device and ask for replacement?!
[Galaxy S I9000 Q&A, Help & Troubleshooting] barakoas:
yes. SAMOLED definitelly suffer from screen retention! i noticed it already when i was playing sudoku for about 20mins few days ago.. its most visible on grey notification bar when u pull it down.. even after 3 mins on home screen u can see ghosts of main dock icons..

about those colour images.. theres easier way.. download "color flashlight" from market.. and theres Rainbow mode under effects.. try it

Edit: i dont care until it become a perma screen burn or really visible .. im used to plasma screens and its fairly similar..acceptable until perma burn!

hmm didnt expect it will be so sensitive but ..well
[Galaxy S I9000 Q&A, Help & Troubleshooting] Srdjan1982:
Yes,it is the most visible on gray,and yes, i have been playing a loooot with the phone in a last couple of days.So,that could be a reason for this.

And for how long i will have to wait for this to disapear?
[Galaxy S I9000 Q&A, Help & Troubleshooting] EarlZ:
And of course all of this is just your theory since I got a AM/PM burned on my Galaxy S w/c i have the screen time out to 15seconds. My phone is about 4 months old, the AM/PM is displayed in white pixels also. I probably have the status bar showing in less than 2hrs a day.

[Q] Burn in issue.

Hi. I've had my SGS for couple months now and I just realised there's a slight burn in at the top left corner of my screen. But it doesn't look like a typical burn in. It's more blueish than burnt (darken). It's bothering me so bad. Does the warranty covers this sort of "ageing"?

Bump. Needs answers. I can't reach Samsung Service Centre. Wth..
[Galaxy S I9000 Q&A, Help & Troubleshooting] cicer0:
Technically it is not burnt in (like it is truly burnt in plasma screens) :

to produce white colour, red, green & blue have to be lid simultaneously.

Blue wears out faster than the other two, so you see a lack of full pixel brightness (blue).

At least I think it's so:confused:
[Galaxy S I9000 Q&A, Help & Troubleshooting] EarlZ:
Ok, so whatever its called its there but when the notification bar drops down again i dont see a lack of brightness on the AM/PM nor do i see a hint of silhouette on the screen.

Top left of screen blue, burn in!!

the top left of my screen in the notification bar has a horrible blue tint compared to the rest of the screen when showing a fullscreen white background.

[Galaxy S I9000 Q&A, Help & Troubleshooting] xmfpdlemalnz@hotmail.com:
First of all, there is no such thing as "burn-in" in oled screens.

It only refers to plasma or crt screens where phosphrous gets "burned" and leaves traces, when static image is shown for a long time.

What we have with sgs is purely degradation of organic pixels.

There is NO CURE for this. This is one of major weakness oled screens have.

Leaving your screen on for overnight is just going to make things worse and shorten life-span.

Blue pixels degradates faster than other colors so be careful of that.
[Galaxy S I9000 Q&A, Help & Troubleshooting] mloc33:
So what`s on mine?

Why only blue?
[Galaxy S I9000 Q&A, Help & Troubleshooting] jimbo_g:
Because blue fades faster than red or green.

OLEDS fade over time, blue faster than other colours. So for example, if you have white text that reads PM in the top right corner of your screen all the time, you will first notice the fade on a full screen blue image the PM area will appear slightly darker where the white text was... and maybe not on red or green full screen images... because white is blue+red+green

are we going to just let samsung get away with this?

seriously I was surprised to find that no one has raised an issue with samsung in regards to burn out on our screens. This is a serious defect which is just not acceptable, we have some people complaining of it within 20 days of owning the phone, we buy phones to last atleast a year not 2 months or less. samsung should not be able to get away with selling a phone that shows an unacceptable level of degredation within the first month. I hear excuses on how all oled displays suffer from this issue, well then oled should not be used in devices with heavy display usage. what is worse is people reccomending to lower display usage and or stick to a specific theme, It should not be expected of me to be extremly conservative with my brand new phone which prides itself in its display technology. We need to get compensated by samsung somehow, warranty repairs are not enough as I am not going to send in my screen to be repaired every 2 or so months. opinions?

[Galaxy S I9000 Q&A, Help & Troubleshooting] Product F(RED):
This is the real reason. Similar to plasma-screen TVs, an image that's static on the screen for a while will burn in. In this case, the notification bar. I thought this thread was going to be about 2.2.

[Galaxy S I9000 Q&A, Help & Troubleshooting] EarlZ:
Im more than confident enough to say that SAMOLED degrades significantly faster compared to the regular OLED screens, probably due to it being able to display brighter colors.

I would consider my phone usage moderate and I dont even use the this phone to browse the internet ( thats the longest time you'll have the clock displayed ) I usually use my phone for a lot of full screen movie viewing. I've got my phone for about 5 months now and the burn out on the AM/PM symbol is pretty visible already when looking at full screen apps/movies that display a bright color in that specific area.

Theres a thread about this over here

http://xdaforums.com/showthread.php?t=892498

I do not mean to be rude or even discredit your methods of observation but would you be able to take a photo of the top right area of your screen while it displays at 50% brightness ( macro mode might help ) under test mode color blue.

As I've got so many iRL friends telling me they dont have the burn out and I personally check their phones for them and it does have.

Not all screens may degrade that fast but soon enough everyone will be affected, its only a matter of time.

I've taken this up to the service center and Im pretty disappointed on the repair terms, I have to leave my phone with them till the stocks arrive for a replacement screen and they cant give me a definite time when the replacement will arrive, they simply cant order the replacement screen w/o my phone with them for "inventory reasons"
