Why does burn in affect OLED TVs but not iPhones and watches with the same type of display?

 

 

 

 

The screen on apple watches aren't generally on enough to be affected and the AOD versions would adjust things I have an AOD on my old samsung note phone and that has never been affected either because it moves the AOD part around the screen. But  know someone with a samsung s22 that has bad burn in from having their screen on bright while outside  for 8 plus hours a day. But I am not sure how much it affects newer model OLED TVs. There was a warning on my sony OLED TV that said I shouldn't use letterbox format  with black bars on the top and bottom of the screen for  too long. 

 

 

Newer OLEDs are supposed to much better for resisting burn in with improvements in screen composition/chemistry and on the software side auto dimming algorithms, logo shifting and pixel cleaning/screen refresh cycles etc.

 

Higher end models with a heat sink layer on the back of the panel are also meant to be better.

 

Have you had a look to see if there's a screen refresh/cleaning cycle you can force to try and reduce the burn in?

I mean - this I feel is some A grade bulls@#t. It's a TV, and lots of OTA, Streaming and DVD's/Blurays (so a large portion of the content you might choose to watch) are letterboxed. I think the tech is not quite fit for purpose if its sold as a general purpose machine, advertised as the best way to watch tv/movies - a premium experience - and then tells you not to do that with it.

 

Yes - I am still frustrated with my OLED getting burn in, and a bit butt hurt about it.

The advice, like most of the info out there, is generalised for letterboxed content. It should be read as don’t just watch letterboxed stuff, watch a range of content including full aspect ratio so that pixel wear is evened out. Same thing with static stuff, modern models average that out though with ‘pixel cleaning’.

Burn-in is just localised wear of certain pixels, OLED comes with the big warning because by it’s nature it can degrade in situations outside of tolerance. One is excessive runtime at very high luminance, this is mitigated with newer panels and software, and the other is outside conditions such as sunlight or excessive temperatures. It’s in the manual and warnings to not have the TV in certain temps or anywhere near direct sunlight.

Again, if consumers situation doesn’t have leeway for those listed above then just get regular LED powered displays.

We have a 2018 Sony A8F TV. 

I had just gone through bunch of 'burn-in' tests via Youtube and can't see any burn in. 

 

I assume that it's related to what contents we watch and how much but generally we don't leave the TV on when not watching and probably play PS5 or watch content about 10-15 hours a week for the past 5 or so years.

Man they really don't make stuff like they used to, my Bravia 55" from 2011 and my 46" form 2013 are both working perfectly

 

EDIT: I should say, I cannot use the smarts on it as the certificates have expired but as a panel with a PC & Chromecast connected it is great

I mean a 2011/13 bravia just has LED backlights. If any fail you’d notice pretty quickly and get it rma’d. OLED each pixel is it’s own backlight, if one dies you get a dead pixel out of 8.3 millionish and the rest keep going.

Yes OLED’s are a bit more fragile but they have benefits for a little less convenience. Until microled becomes affordable in the next 5-10 years OLED is the best alternative.

Are MiniLEDs supposed to be better?

sonyxperiageek: Are MiniLEDs supposed to be better?

 

 

 

The Hisense TV I just bought (and TCL I looked at) are both MiniLED. These give hundreds of dimming zones, which give very good contrast (but not as good as OLED to be clear). If you watch a white box float around your screen you can see some flickering as it changes zones, but in real world viewing don't notice anything.

 

There is a lot of dependence on the individual tv manufacturers algorithms to make this work well - from the reviews I read Sony is by far and away the best, and charge accordingly for it. 

 

From my PoV the Hisense and TCL's do a pretty great job for the price. This year MiniLED seems to be creeping down the models as well.

I have a 65" 2017 LG C7 from new. No issues at all. I game and watch movies from disc/streaming on it. What i dont do is have it on vivid mode or any other eye searing mode. I just use the ISF Modes for SD/HDR stuff or cinema dark for Dolby Vision. Havent had burn in issues of any sort.

I have seen chronic screen burn on a Samsung S9 (AMOLED) that was heavily used. (yes, its an old phone but it takes time to manifest).

Hey all.

 

Our 2018/19 LG 65" C8 OLED TV has some noticeable burn in now so looking to get a replacement.
Just wondering if there is any resale value on it? even if its only few hundred bucks (It cost me $5399 at time of purchase)

 

When I say noticeable I mean, in some scenes you can see faint outlines along the bottom where TV channel banners have been, and there is a bit of a decent size blotch down the middle of the screen but it's not noticeable in a lot of scenarios.
Example, It's quite noticeable in something like Mad Max fury road with all the yellow sand and blue sky scenes, but not really noticeable in say a Marvel movie... So scenes where there is a lot of action and colours (action movies, Scifi, fantasy etc) its hard to see but scenes with only a few colours (Westerns) on it can be more noticeable.

 


I would be very up front about the burn in of course but I just want to know if its worth trying to get anything for it. It's still a decent TV in most scenarios.

 


Thanks in advance.

 

 

 

 

Can I ask, did you end up getting anything for your C8? 

 

I am in a similar boat, currently with a 2018 LG C8 55" OLED, with what looks like similar burn in, faint outlines along the bottom, eg the TV One logo, also with a dull patch in the middle of the screen but only when displaying certain colours, like red and yellow.

 

Its more than watchable, its just become overly obvious to me because of OCD, and I cant avoid seeing it now.

 

I'm about to pull the trigger on a replacement, and now going through the motions of what to do with the existing tv, trying to sort something so that I can divest myself of the current one once I know the delivery date for the new one.

 

I am thinking Trademe $1 reserve, unless someone here is interested. I havent pursued LG for a CUG claim, it was purchased from JB HiFi in June 2018, and has 15440 hours run time.

No bites yet mate, will let you know on Sunday when the Auction finishes.

 

Yep your description is bang on to what I have for burn in.

 


Have you chosen your replacement TV yet? I ended up getting the LG 75" QNED86 for around $3489 on sale, pretty dam happy with it too.

Televisions are still consumer goods, not capital goods. That's why I don't spend more than €500 on a box like this, no matter what kind of amazing display is available at the time, I buy the best screen for this fixed amount and that's it. Good sound and smart functions are ensured externally, not in the television. But here in Europe, televisions are also thrown at you at extremely low prices.

Yes we got what I think is a fantastic price on the 2024 Samsung 65 inch QN90D Neo QLED. The best we had seen them was around $3600, but managed to purchase at Noel Leeming for $2907, plus they had a $250 gift card promo running which we can use on other appliances we need, so taking off the gift card, all up the QN90D is $2657.

 

Went for QNED as I now have fear of future OLED burn in, and realistically after spending over $3K on the LG OLED, I expected more than 6 years use from it.

So I finally got this sold, tried 3 times on Trade me, and neighbourly.co.nz as well got some interest but not bites. So I ended up putting it on Facebook Market for $150 and I ended up getting 14 inquiries about it.
I possibly could have got $200 for it but I just wanted it gone.

 

If you still have your TV you could try there.
