Scientists Develop a Solution to OLED Burn-in
OLED is the future of flat screen displays, as they provide superior color reproduction, dynamic range, response-times, and energy efficiency, over LCD. The latest crop of OLED panels powering notebooks and desktop monitors, however, have a problem that wasn't as prevalent with OLED-based televisions—burn-in. This is what happens when an OLED panel displays a static image for too long, causing regions of the panel to permanently discolor. Some PC monitor makers are jumping in to offer extended warranties against burn-in to their customers, as they realize that they just sold an expensive, exotic piece of technology that could potentially degrade within- or not long after their standard warranty periods. Scientists at the University of Cambridge think they have found a breakthrough solution against OLED burn-in.
Scientists discovered that the main culprit behind OLED burn-in is the blue diode. The blue LED has been an elusive technology that only came into existence several decades after green and red. It's only with the arrival of the blue LED that white could be made, turning LED into mankind's primary lighting source, and eventually the OLED panel. Blue is a relatively higher energy diode, and uses more exotic GaN substrate. The Cambridge scientists discovered that jacketing the blue diode alkylene straps would cut down burn-in, and make the manufacturing process more efficient. They have published their method in the Nature magazine. Unfortunately, it will be a while before display manufacturers take an interest in the new method, and re-tool their OLED production lines to incorporate it—we imagine at least a couple of years.

That highlighted box would be clearly visible on PS dashboard after playing just few races in that game.
Granted, this is temporary and would go away after some time but still.

Thanks for linking it!
...and Fusion is a lot closer than 20yrs away, progress is happening at an exponential rate now that there is a financial imperative to make it happen, which wasn't the case in the care free fossil fuel burning past.
MiniLED is fantasy. Yields are worse, reliability is worse, its more expensive and if it lasts too long they can't keep selling panels with it.
Not happening anytime soon.Yes, but that was happening anyway. QD OLED is simply vastly inferior.VA's higher static contrast has always been its most defined plus.Yep, I've always got an outlook mailbox plastered on my IPS laptop at the end of a work day :D
But then again no LCD is great in a TV unless its FALD
No hate on anyone's OLED they're awesome but the burn in is still a huge concern for many and will be until it's resolved.
On the other hand mini LED bridges the gap perfectly well and imo is only not seen more because manufacturers have decided to focus on the disposable OLED pipe dream. Yes, you get blooming on very small objects, but with reasonably large number of zones that's a non issue.
These are my observations. The contrast and colors thing, yeah. Totally amazing on OLED. I do have burn issues on my OLED phone, tablet, air cleaner and washing machine display. I got 0 issues on my 10-20 and 25 year old displays. I still use them today too, cus they look the same they did when i got them. If they got lower brightness or worse colors, i can't really notice it over the huge amount of time. OLED burn? That's easy to notice and fast too. Even when you try to ignore it. This is why i ain't buying OLED, not before this kind of new thing is a reality, not just part of the daily news.
When I showed my cheap IPS phone to a colleague of mine the other day, she said the screen has great colours. She's been using a Samsung OLED for the last couple of years.
But those drawbacks still exist, but most important of all: Pretty lights are pretty, tbh.
Sometimes the way a product can basically go EOL can benefit me. It is usually those products that I use everyday and actually see advancements. "Oh no! Honey! Come look at this! The TV is dead. This really blows. I'm going to be right back and pick us up a new one. Costco has XX Model on sale right now and the deal expires in 3 days."
This kind of reminds me of the battle between TN and the early IPS panels. Some people swore with their lives for the superiority of the TN response time, while I always preferred colour accuracy (not at the cost of burn-in, though, as I find that unacceptable).
In terms of color reproduction, OLED have better contrast but worse color accuracy. IPS is still used widely for color checking and photography (especially as static elements are common in those trades).
This whole article is pretty much worthless, just another "breakthrough" that will likely amount to no real world impact. Author was definitely baiting engagement by making the claims they did, particularly the one regarding energy efficiency.Well TN was the only way to get lower response times aside from going back to an old CRT so makes senses. I assume at some point burn-in for OLED will be a non-issue and they'll improve the energy efficiency but it could be a few years.
Edit: Even if you disagree with my sentiment, I'm sure you agree that selling your old TV would be way better than just replacing it. Stuff going EOL prematurely benefits no one.TN was the way for lower response times, but I didn't care because it came at the cost of worse colour accuracy. Just like I don't care about OLED because it comes at the hefty cost of burn-in.
This new technology is gonna be too late for my monitor, which already has a severe burn-in ;)
