Help Super Amoled Plus

Just wondering, I've seen a few complaints about the Amoled screen getting burn in. Should this be a problem with heavy usage? I know the top high end models feature them (Galaxy Nexus etc.) so it can't be that much of a problem can it?
 
It's mostly an issue with the Galaxy Nexus since there's always on-screen buttons showing. This means the bottom strip of the display wears out slower than the top. You can see this issue when playing video and the buttons disappear.
 
I have noticed Image retention on the S2. Especially on grey screens like Market.

I suppose if you left the screen static for a long time and repetitively you will get burn.

This is a truth about OLED that seems to be hidden - even TV's.
 
No problems here either. I imagine your own brightness levels might also be a factor for some screens as well as timeout settings. Mine is never higher than a third on brightness, timeouts to minimum and touchkey lights set to always off.
 
Hi!

I wanted to ask if its true that the galaxy s2 has a display which will be worn out faster than say the iphones display because of the S-Amoled doesnt last as long as f.ex. iphones display? :(

I know that you probably buy a new phone before it gets worn out, but im still curious

No? I take it Samsung are out there to make a quick buck by providing a nice contrast screen that won't last long

Quick buck? You do realise that OLED is very expensive to manufacture, right?

They do it because by selling the displays they can fund development. OLED displays use less power than LCD, have perfect viewing angles, amazing contrast ratios, and tend to be thinner. That means compact devices which last longer, and look great. The trade off is minor burn-in, but that's improving all the time. It's the technology that will eventually replace LCD, starting with phones, then TVs, then eventually PCs (if they remain relevant).

Its expensive to manufacture so what. I'm saying they are making a quick buck by selling non sustainable technology which will be useless after say a years use. They don't include these details when advertising the 'SuperAmoled+', I beleive its something, us as the consumer should be informed about when considering to purchase
 
What good is there buying a top high end phone to have the brightness dimmed and timeout settings to a minimum. Lets buy a Lamborgini and only drive it up to 60mph because the wheels might break off

Also does the display degrade in terms of colour reproduction, contrast and brightness over time? As the individual pixels begin to lose their abilities
 
This is why I went for the Arc which has an LCD screen. I had a bad experience with my Desire (AMOLED screen), which suffered badly from screen burn. I had the brightness at around 85, so okay I was asking for trouble but I wanted to get the best out of the display. The burn in happened only after 6 months of having the phone. Display technology may have improved since the Desire, but having read that some Galaxy S2 users are having the same trouble I am pleased I haven't bought or intend to buy another device with an AMOLED/Super AMOLED plus display.
 
Omg.. this is bad news. I should have bought the iphone instead then?
Is the Galaxy SII display really that bad and short lived compared to LCD?

Permanent Screen Burn-in (image burn-in) of super AMOLED (Galaxy S) - YouTube

Err :( I hope the SGIII has this problem solved

OLED is a self-illuminating technology like CRT and Plasma.

It hasn't been talked about much and a lot of it has been kept quiet but OLED DOES suffer from Image Retention and Screen burn.

So the S3 will be no different.

Image retention will be more common.
Screen burn will require the cells to age faster than surrounding cells and produce a dimmer or different coloured image permanently. You would have to work pretty hard (like CRT and PLASMA) to do this. Todays Plasma TV's and even CRT is very resistant to this sort of damage.


Like I said, I have seen IR on my S2 - Brightness at default (about 40%) Its only visible on gray backgrounds that dont fully illumanate the cells again- and even then only for a few seconds.

(a) it minimises unnecessary battery usage as the display is by far the highest consumer of power. What good is there having the screen on if it's not required?

(b) Personal taste. I personally find the display much too bright by default, and reduce it for my own comfort and convenience.

I've already told you I see no problem with my display. Others have differing experiences. Read the following topics and decide for yourself.

Thanks for the in depth information. I'm currently using a computer with a CRT monitor and it seems fine, so it can't be that serious? I tried the grey image on my screen and yes it does leave a retention even on this CRT I suppose lol when I'm flicking from this text and onto the grey

yeah- you see it on the S2 also- I have only seen it a few times when going from one screen quickly to something pan - like grey or similar mid-tones.

The IR is usually from "exited" gases, phosphor or oled cells. Burn is kinda the opposite - a premature ageing and dimming of cells /pixels.
 
So does this ageing and dimming of pixels mean the screen will likely give a less 'stunning' picture? even if there is no burn in. I believe burn in is only caused when you leave a non moving image on for a long time?

Over time the OLED cells will age, this will cause colour change and dimming. So yes, if you keep your phone for the next several years it will change.

OLED at the moment also ages faster than other technologies. Sony's first OLED TV screen in 2008 were quoted at 5,000-14,000 hours. Blue cells aged almost 2 times faster than Red and Green.

I cant find quotes for Samsungs OLED's used in Phones.

Burn-in will be hard to do. You will have to have the same image on the screen for long periods of time for days and days on end to age the cells enough.

OLED is also highly susceptible to moisture and this can damage the screen.

Its a new technology however. There will no doubt be improvements all the time.#

Sadly recent technical reviews have reported the LCD used by apple is still more efficient and brighter than the OLED's.
Samsung also need to tone down there colour.. It looks stunning at first but is technically way too saturated.

OK. Thats it. I'm planning to have my S2 for some years, but now im going back to LCD.
 
This is really worrying, so if there is a part of my screen which commonly displays blue it means that part will wear off quicker. Meaning after a year or two my screen will be uneven with some pixels brighter/colourful than others. :(( I can't be having this on a phone I want as a long term investment. I would buy the Samsung Galaxy R but its not available in the UK, I have to hope for the Samsung Galaxy SIII and whether that will be any different

Not that bad.

If you used the screen 3 hours a day it would be 7 years before the 8000 hour Sony quote would be up.
The other colour would be ageing too. We wont know fully until the screens age but in several years time OLED's of today (if still working) wont be the same- probably green/yellowish and slightly duller.

The S3 will also be OLED so it will just be the same.

Samsung may have improved OLED however since 2008.

But yes. OLED technology isnt all gold plated as made out.
