LG Display Unveils Next-Generation OLED TV Display, the OLED EX
LG Display, the world's leading innovator of display technologies, unveiled today its newest OLED TV technology OLED EX. The next-generation OLED EX display implements LG Display's deuterium and personalized algorithm-based EX Technology, which helps boost the innovative display's overall picture quality by enhancing brightness up to 30 percent compared to conventional OLED displays.
The OLED EX name is an acronym of "Evolution" and "eXperience", which represents the company's goal of providing customers with new experiences through its ever-evolving OLED technology. OLED displays are self-emissive by nature with their multiple millions of pixels emitting light independently without a separate backlight source. This distinctive characteristic lets OLED EX achieve the perfect black, rich and accurate color expression as well as an extremely fast response time.Since 2013, the year it became the first to mass produce OLED TV displays, LG Display has been consistently improving its leading OLED technology. OLED EX is the result of the unparalleled knowledge and know-how the company has gained over nearly ten years of developing OLED displays, created to deliver the most lifelike images that transcend the limitations of a conventional display.
The EX Technology applied to the OLED EX displays combines deuterium compounds and personalized algorithms to enhance the stability and efficiency of the organic light emitting diode, thereby improving the overall display performance.
Thanks to EX Technology, OLED EX displays unlock new levels of picture accuracy and brightness to accurately deliver exquisite, realistic details and colors without any distortion - such as the reflection of sunlight on a river or each individual vein of a tree leaf.
Deuterium compounds are used to make highly efficient organic light-emitting diodes that emit stronger light. LG Display has successfully converted the hydrogen elements present in organic light emitting elements into stable deuterium and managed to apply the compounds to OLED EX for the first time.
Deuterium is twice as heavy as normal Hydrogen, and only a small amount exists in the natural world - as only one atom of Deuterium is found in about 6,000 ordinary Hydrogen atoms. LG Display has worked out how to extract deuterium from water and apply it to organic light-emitting devices. When stabilized, the Deuterium compounds allow the display to emit brighter light while maintaining high efficiency for a long time.
In addition, thanks to LG Display's very own 'personalized algorithm' based on machine learning technology, OLED EX is more in control of its own device. The algorithm predicts the usage amount of up to 33 million organic light-emitting diodes based on 8K OLED displays after learning individual viewing patterns, and precisely controls the display's energy input to more accurately express the details and colors of the video content being played.
LG Display has also upgraded its designs through the new OLED EX technology. By utilizing its innovative EX Technology, the company reduced bezel thickness from the original 6 mm to 4 mm based on 65-inch OLED displays. By reducing the bezel thickness by 30 percent compared to existing OLED displays, the OLED EX display creates an even more immersive viewing experience all the while delivering a sleeker and premium design.
LG Display plans to strengthen its leadership and product competitiveness in the large-sized OLED business by integrating OLED EX technology into all OLED TV displays manufactured at its OLED production plants in Paju, South Korea, and in Guangzhou, China, starting from the second quarter of 2022.
In 2013, LG Display's first year of starting mass-production of OLED TV displays, the company sold 200,000 units and by early last year recorded accumulated sales of 10 million units. In the two years since then, the company's accumulated sales have doubled to surpass 20 million units globally.
"Despite the global TV market experiencing a 12 percent decline this year, we still observed a 70 percent growth in OLED sales," said Dr. Oh Chang-ho, Executive Vice President & Head of the TV Business Unit at LG Display. "With our new OLED EX technology, we aim to provide even more innovative, high-end customer experiences through the evolution of our OLED technology, algorithms and designs."

No burn in yet... Unfortunately since i've got about 6 months left on that best buy burn in warranty :/
I always turn down the brightness a bit so idk how hdr is gonna work well if at all.
TVs also have this thing that detects static stuff (logos) and dims them. I hope monitors will do the same, but this will interfere with color critical work - you'll have to turn it off then. Sounds like you're assuming "bright" is always about whites...
In the meantime, my CX looks anything but desaturated.
The way it works is that most ordinary displays have RGB (or BGR) subpixels. W-OLED is unique in that it has a fourth subpixel for white, making it WBGR. The fourth white subpixel serves no purpose in adding to color definition, since it's white. Instead, its sole purpose is to enhance brightness. The colored subpixels are actually heavily filtered white LEDs. The color filtering process is lossy and much brightness is lost to it. The white subpixel is unfiltered white, and it shines more brightly than the others because of this. So as a trick to the human eye, when they want to enhance brightness they make the white subpixels bright, and this makes the scene appear more bright overall. But since it's just the white LED getting brighter, it's not providing a lot of color definition. In most normal scenes of regular brightness, W-OLED displays are perfectly saturated. It's the bright highlights where color definition is lost due to this effect. This is also why color volume graphs, such as in this review, fail to show top-tier results for what is otherwise a great display.
from software to hard ware side. also proper calibrating to.
games... ahahaah
dev really dont like standards to follow.
hdr is one of those that super ridge . for a reason.
so instead they will bs it and use auto hdr(which is fake hdr)
In defence of OLED, this was almost 7 years ago now - OLED may have improved dramatically WRT burn-in and that's why I'm interested in feedback on current gen. 9 out of 10 times you want peak brightness, it's white or almost white so W-OLED is fine.
Occasionally you want OMFG colour pop and that's where white OLED falls short since it can display a 700nit white but only a 350nit colour image. If you have the brightness cranked in a bright room or direct sunlight W-OLED is going to look wrong.
On the other hand, if you bought an OLED TV for a bright room then you're doing it wrong; OLED's biggest strength by far is black levels and contrast, both of which are ruined in a bright room. Response time is amazing too but with the primary content for TVs being 60fps or slower, the response time really isn't that much of a game changer.
The hard part about HDR is the actual dynamic range. LCD can't meet that without resorting to local dimming - and nobody has figured out how to do that without breaking the bank. OLED is the only one suitable for HDR (ok, it won't work if you want a TV in the bar on the beach), but OLED isn't cheap either.
I do think it's worth being cautious about burn-in with OLED panels, even if there are many people who happily use OLED TVs as monitors without any noticeable burn-in. The posters in this thread are right—taking extra steps such as lowering the brightness to 120 or 100 nits, setting a dark background and using dark mode for your apps, and setting your task bar to auto-hide, will all help your display last longer. These aren't options for everyone, though, and OLED displays aren't appropriate for every use case. I work at home, and my work PC is also my leisure PC. It's also in a well-lit room. I'm used to 200 - 250 nits, not 100 - 120. I also have static interface elements on screen for 8 - 12 hours a day, every single day. There's no getting rid of them. And going full dark theme for everything is just not how I want to live my life, lol. I'll choose to hold out on OLED as my main PC display until there's a panel that can last 5+ years for less while being on with static interface elements for 3500+ hours each year. It's a pretty demanding requirement, and I'm guessing we're still quite a few years away from that being possible. In the meantime, I'll happily buy an OLED TV for the living room. :)
Similarly, Samsung is quite hush-hush about what exactly QD-OLED is. They have clearly tried a number of different approaches with varying levels of success. What we know is that QD-OLED uses blue OLED functioning as backlight. What is going on on top of it is where things get muddy.
- The most official-ish description for now seems to be that there is a QD layer with QDs to form red and green subpixels and backlight is directly used for blue. This does sound exciting and viable enough in theory but there are a couple nagging problems that I do not really see them having resolved just yet.
- A slightly different method was described a little while ago that I would suspect is what Samsung actually does - take the light from blue OLED and run it through QD filter to get a light with spectrum that has nice clean RGB peaks and run that through color filters. Essentially the same idea of W-OLED but white OLED being replaced with blue OLED plus QD filter.
It's an exciting tech for sure. It'll just be very expensive to start with. There's also talk of displays in the future that will be fully quantum dot driven in some manner. I'm not sure what the theory there is (it was brought up in the Linus Tech Tips video where they toured a quantum dot production facility)
Alternatively, types of quantum dots can be excited by electricity, emitting light. These are used and driven similarly to OLED with the exception that light emitting part of the LED are quantum dots instead of organic stuff. Only experimental panels for this have been created and there seems to be a whole host of problems with getting that technology ready for mass production. Exciting tech but seems to be further away than microLED or by some accounts too difficult to make viable at all.
Sat here on my 4K 120Hz 65" Samsung that has really flaky first-gen VRR support, I want a better TV but it's genuinely great and would do everything I needed to even if it was only 60Hz 1080p, all I really care about is black levels in a dark room and VA's good black levels and high contrast will suffice to quell my "urge to splurge" on OLED for a couple more years I hope.
But for those using blinds or watching in a darker setting, OLED is plenty bright. OLED doesn't have burn-in.
OLED can suffer from uneven wear, but it has nothing to do with pictures being static. It's caused by areas being significantly brighter over time wearing those pixels more than the others. This will happen regardless if the picture is static or changing.
E.g. if you watch a news channel all day, you will probably see uniformity issues where the news anchors and news tickers are positioned on the screen, even though they are moving.
Still, unless you are taking it to extremes, panel uniformity after several years of use will still beat any LCD. Why? Have you experienced panels wearing out with normal usage?
The good old CRTs typically lasted 30-40 years of daily use (let's say 3-4 hours/day). Plasma panels generally last >15 years, LCD probably 10-15 years (depending on quality), but with OLED I don't know yet.
My primary concern with TVs today is the software breaking, an intentional hardware failure(usually bad caps or solder), or they somehow become obsolete before they break down. This is one of the reasons why I wouldn't pay a lot for a TV, because I expect it to fail after ~5 years.

A pro-tip for TV buyers;
Generally speaking, there are at this point few improvements year-to-year for OLED TVs, and all OLED TVs have great panels (the same panels). So unless you strictly need a new feature, grab the previous generation on discount. Nearly every year I've seen them 40-60% off in Q1 the following year, that's the time to buy!
The uneven wear for OLEDs on plasmas can be "reversed" by applying wear to the rest of the screen to even out the problem, or even just changing your usage of the screen. Uneven wear is much less of a problem for OLED than plasmas, where in OLED it's mostly tied to very bright areas.
And FYI, LCDs also have wear on pixels, typically causes by sharp lines of contrast over time, causing the TFT panel to wear out in those spots, creating lines or shadows. Ironically, this is closer to a "burn-in" than anything that can happen on an OLED display. :P
