Iteration: New OLED Manufacturing Tweak Improves Efficiency, Longevity by 15%

[Raevenlord]

While OLED is generally seen as offering the overall best picture quality of any current, consumer-level display technology, one flaw has always been pointed to the technology: its longevity. As time passes, OLED panels tend to lose their vibrancy, and are prone to pixel burn-in (as in, when static images are projected on the same pixels for extended periods of time, they tend to "memorize" the color and be locked in to emitting it). However, the incredible image quality given by OLED's contrast capabilities (where each individual pixel can reproduce pure black, in virtue of being off) means that researchers and companies have poured countless dollars towards improving the technology for commercial use.

Of course, tech is all about iteration, and there are always ways of improving a design - or the underlying technology. In this case, a team of German and Spanish researchers found that raising temperatures in the OLED panel manufacturing process (heating the polymers to within 80 to 90 percent of their glass transition temperature) allows for the creation of "ultrastable glasses." This means that the polymers are now arranged in their best possible configuration - at their lowest energy state - with smaller gaps between the material, which improves panel cohesiveness and reduces particle vibration. The result? Longevity and brightness increased by 15% over their non-heated counterparts. Now, the researchers are working with OLED manufacturers to try and implement this technique at the manufacturing level - at a sustainable cost.

Now all companies are heavily investing their R&D into micro LEDs. OLEDs are slashed as mistake with little perspective to be fixed (lifetime and power efficiency)

LG just built a new 7 billion dollar factory for OLED two years ago, they knew about Micro-LED then too, I assure you they are fine with still being king of OLED TV market.

Personally I think this is great news, I can't wait to see OLED and Micro-LED side by side at Best Buy to see which is going to be my end game.

 

[S@LEM!]

Yah, Micro LED seems far away from manufacture mass production. the cost is high or the process is unstable, I hope to see it in the near future.

OED is still maturing, which is why I'm not updating my plasma TV to OLED for another few years at least. Given the high prices, it'd suck to miss out on this breakthrough. Hopefully TV's get this by next year or 2020.

Not all companies, mostly just Samsung for missing the boat on OLED. But micro led has a long way to go still.

Actually, Samsung is doing alright on OLED's. They just aren't focusing on TVs like LG is. They have all their OLED's going into smartphones and tablets. Their belief is the same as the article states... "OLED is best used on low power devices, not devices that may stay on for thousands of hours."

If you could see my Note 5 screen, you'd know what I am referring too.

I have watched thousands of hours on my ZTE Axon 7 OLED (which i think is calibrated colorwise better than my brothers galaxy s8) of netflix... 0 burn in issues so far. by the time it dies on me im hoping it will be 2019 and micro led will be a thing haha

Or Samsung's implementation of OLED simply isn't up to standards and to do it right they need LGs technology, which is the real reason Samsung is doing what it does. Your Note 5 completely counters the argument of it being for low power devices.

Remember plasma had similar problems. Later generations of plasma however, did not.

 

[StrayKAT]

I just bought a new Samsung myself, but even pulled away from OLED despite that. Gonna be using it with a PC and have it on a lot.

 

[AsRock]

This just means more money for them, don't really do any thing for the customer for the most part.

Websites are scrambling to make OLED TV's look bad because of recent advancements, and by doing so help they help big paying advertisers, because LG isn't one.
