OLED begin to have dead pixels after the warranty expires... Unbelievable!

[Andrewtst]

OLED displays are extremely short-lived... I bought the LG C9 in August of 2020, not even 3 years, and today I noticed so many dead pixels on the top right corner...

 

I only use this as TV purpose mainly for Netflix, Apple TV+ and Disney+, never use for monitor purpose.

So far, there has been no burn-in, but this is the first time I've encountered dead pixel spreading on a display that has been in use for less than 3 years...

 

The warranty period is 2 years, and they begin to exhibit bad symptoms after the warranty expires.... 

Now I am regret for not purchasing an extended warranty for it.

 

Now I totally no confidence to plan use OLED panel display as PC monitor. 
The TV distance put is far, and dead pixels are unnoticeable, but this is not the case if used as a PC monitor.

OLED has improved a great deal the last couple of years but I tend to agree. I just went high quality NAN0 IPS as I generally game on my PC and on some occasions watch a movie but I was simply so aprehensive about burn in etc as many games I enjoy have so many items permanently on screen. Huds the map often the chat box etc etc..

Plus my last good quality 34" IPS from Dell is over 7 years old and still perfect. It is now hooked up to my wifes PC as it was 60hz and I wanted 144hz for my gaming.

It will never have the deep blacks etc but it is not alongside an OLED that makes me see the difference. I suppose i fit the category of what i have not had I cannot miss.

Everyone is concerned about burn-in, but I'm dealing with dead pixels now which seems no one talk about it much...

 

My monitor now is mini-LED VA, which is great for HDR movies and gaming but still not as good as an OLED for displaying very dark scenes.

It is clearly superior to any type of IPS (I also use nano IPS previously), but still it cannot compete with OLED.

[johnno23]

I suppose not enough people adopted the tech relatively early on and the issue you have with the dead pixels is only now begiinng to come up. As more people have the issue the more attention it gets I suppose is the reality.

But if this the case, OLED is too fragile. The cost of it ain't cheap. 

[johnno23]

I would agree. The cost of OLED measured against an IPS is quite extreme. I personally love the implentation of OLED on small screens but from my personal perspective I find the technology to be too expensive for larger screens and simply do not have the funds to invest and hope that the screen will have the same lifspan of tried and tested tech.

I remeber the move from tft to ips and also the costs involved. i remeber the jump from 13" monitors to when 17" was the holy grail etc etc.

OLED I would never say is bad but the tech and its ability to offer a value that can be measured in years of use just is not there yet. that of course is my personal opinion. But your post just makes me happy I chose an IPS and not take the plunge and go OLED. Sadly you now have an issue that really should not occur so soon considering the price paid. 

I imagine that if you remain on OLED with any new purchase it will be better but how much better I think is guess work. Phones etc other small screen appliances using OLED are often replaced long before real issues occur and the markets simply use it to their advatage. I have an iphone non OLED but the phone is already 6 years old. Compared to the people around me I am an exception to the rule as almost no one i know has a phone more than 2 years old.

It would appear that this was not true to real life and they simply used some clever math and software to derive their claims.

the source was from here https://www.howtogeek.com/687180/oled-screen-burn-in-how-worried-should-you-be/#:~:text=In 2013%2C LG Electronics claimed the expected life,six to 10 years%2C according to one study.

In 2013, LG Electronics claimed the expected life of an OLED display was 36,000 hours. In 2016, though, the company increased this to 100,000 hours, or 30 years of watching 10 hours of TV a day.

My fridge never fail after 18 months.  Cars need change oil is not faulty as it can be change. My phone battery also never die after 2 years.

My C9 also has a few dead pixels. But they're only single pixels here and there, and not visible from a normal TV viewing distance. They're not all in the same spot like in your case. I've seen so many more threads about dead pixels on LCD's. Avoiding OLED won't help you in avoiding dead pixels. It's a problem all display technologies have.

 

In general i'd say as long as it's not distracting in real content, it's not a problem.

 

A 4K WOLED display has 33.177.600 small LED's. A few of them are bound to die in a few years. Expecting anything else is simply unrealistic imo when we're talking about these numbers.

I'm fine with TV because it's unnoticeable due to far distance.

 

But for the monitor, I need to think twice now because I am facing the dead pixel all together in one area which indeed shocking me and it will be very visible if used as a monitor due to closed distance. If there are a few dead pixels here and there, I am fine with it because they are not very noticeable even at monitor usage distance.

In a few years I'll see how my C2 monitor holds up. Until then i won't make any conclusions. But again, LCD's also often have or develop dead pixels.

Honestly though, you can hardly see dead pixels from a monitor distance either.

 

Modern OLED also have a longer warranty period (C2 has 3 years - burn-in included) but yeah, in general I do expect OLED to either die or have a major compromise around 3 years time. Which is fine, I'll probably been looking for something new by then anyway. 

 

OLED monitor like the one from LG also have MLA while have a slightly worse brightness than C2 so they probably take output a lot more actual light and that might help significantly with burn-in

For one or two dead pixel - yes cannot see even on monitor distance.

For what I face on my C9, it is too obvious, even in white background now I can see it at TV distance where that corner like being bite of a little.

 

3 years cycle and need changing TV is not something I will do.

It should be at least usage for 5 years as minimum.

Well, there's a reason I prefer LCD in the first place.

 

But so long as display techs remains exciting, I am happy to upgrade my display every 3-4 years. From QD-OLED to MLA, there are enough excitement for me to go on about with this hobby. Maybe until we reached a holy grail of micro LED or a mini-LED LCD that don't suck at local dimming I guess but until then, I've already spent 800-1000 buck on a display every years anyway - I've resigned myself to the fact that I'll probably couldn't control myself when the next best thing hit the self

micro LED is also emmersive displays, I believe it will have burn-in issue as well.

 

Local dimming is not design for Windows, lucky both my Samsung Odyssey support only on when HDR content detect and not on in Windows environment.

At some point it will probably die - but that's applying to just about any display. During rting torture test for both OLED and LCD, eventhough LCD do last much longer than LED, all of them die all the same in 5 years or so. Nothing last forever, that's just the nature of a modern consumer tech. 

 

Still though, micro LED use none-organic LED, just like your modern LED light. It should be magnitudes more durable than OLED and if it last you 6-8 years instead of 2-3 that's probably more than enough to justify a longer term investment.

I saw exact same issue at work on a brand new C9 that was in storage since 2020. Same exact issue with just tons and tons of dead pixels around the edges. It is so many that I stopped trying to count, so as a monitor it would be awful, at TV okay but still pretty crap given the cost of these devices. So clearly thus shows either bad QA or that lixel material degrades over time regardless of usage, or both. I haven't owned my personal oled (Alienware 34 and Sony 65" A80K) long enough to know but I did get extended warranty for both. Also of note is that LG quality is crap these days, regardless of panel tier. I had issues with both of my high end LG IPS panels literally weeks after warranty ended. I am not into conspiracy theories but this makes one wonder...

I want OLED as monitor, but after this issue, I on hold 1st, some more they is no higher resolution OLED gaming monitor yet and also no standard RGB alignment yet. I will hold my OLED monitor purchase until year 2024 to see how the new release.

[eXpired56k]

Yeah, there are definitely some disadvantages and due to pixel alignment image is a bit soft but it isn't that bad. Given that LG started making high end IPS gaming monitors it was only logical to switch to OLED once my UltraGear 34 died after around year and a half of use. VA monitors IMHO look awful so I had little choice. Image quality on an OLED is outstanding, and while not entirely happy about changing my habits, I let it sleep to help prolong the life and reduce burn in. OLED does have very nice pixel refresh and low persistence, it is very noticeable. I run my AW 34 at 144hz 10pbb and it feels a lot better than UltraGear IPS 144hz 10bpp. For workstation use I was unhappy with softer image for a few days but it isn't that bad. AW being a QD OLED has a better pixel structure than LG panels, which matters for monitor use. Though I am not seeing that much of a difference compared to my Sony TV which I think has an LG panel. Just my personal observations and thoughts.

My LG G1 developed dead pixels while sitting unused in the box for 2 years. There were no dead pixels when I boxed it up. I unboxed it yesterday and there is an irregularly shaped strip of dead pixels near the edge. It's as if the panel got damaged from pressure just sitting in the box.

That's why you store every boxed display face up with nothing on top of the box. Pressure can damage every display, not just OLED.

It was stored vertically just like the instructions on the box.

I'd still not recommend that because this way there can be pressure on the display panel. That won't happen if you store it face up.
