Samsung Working on OLED TVs based on Blue OLEDs and quantum dots
Will it finally happen? Samsung supposedly has been showing prototypes of OLED TVs in of 55 "and 65" sizes. The new OLED screens would use blue OLEDs combined with red and green color filters based on Quantum Dot technology, in essence making this a QD-OLED display.
If you can remember it, Samsung in the past already had offered OLED for TVs screens but halted production due to issues with the technology. They fabbed them with RGB subpixels, however, over time the color balance deteriorated because the subpixels do not degrade equally. Samsungs main competition, LG, bypasses that effect by using white OLEDs and then applying color filters, it's however patented technology so only LG may fab these. That is the main reason why you only see LG OLED TVs, or OLED TVs from other brands based on an LG panel. Samsungs new technology will not make use of a white OLED, but it invokes blue colored OLED with red and green filters. Combined with what is referred to as Quantum Dot Color Filter (QDCF).
The prototypes apparently have been shown at CES, however, they are not yet ready for prime time reports tweakers via reports eetimes. QD-OLED method can potentially produce even thinner and lighter TVs compared to the current Quantum Dot panels that are commercially available. The number of components is reduced, it is also possible to improve the viewing angle and response time, which are a limitation of regular LCD TV. The main thing, of course, would be the exceptional contrast ratio as black is black, an OLED pixel disables itself with the color black). Next, to that, no bleeding or clouding would be present as well. Samsung new screens would be preparing QD-OLED in 55-inch and 65-inch sizes. The product prototype was unveiled at CES 2018 where it showed the new technology in a private room.

Probably a while still: https://www.rtings.com/tv/learn/permanent-image-retention-burn-in-lcd-oled
I know they sell OLED monitors now but I wouldn't buy one. LG's latest TV's (I have a C7 myself) burn in with static content after about 6 weeks. Granted they run the test for roughly 20 hours a day, but still.. if I'm going to spend $1000+ on a monitor I want to know 100% that I'm not going experience burn-in within a reasonable timeframe. Even with my C7 I find myself getting paranoid when I walk away from it when it's on or playing games on it because of experiences I've read people have with HUD's getting burned in.
They would need to prove to me somehow that the burn-in issue is either resolved completely or resolved enough where they could warranty the panel for at least 3+ years.
I suppose this could be a return for screen savers!

Samsung is using their own QD technology with OLED and that's somehow a workaround to LG's solution? Dafuq?
Not only does Samsung's QDCF tech differ from LG's own filters, you also have a blue instead of white backlight meaning you can rely on the backlight itself to produce the blue hues. That's a significant difference as they'll be using 2 filters to simulate the entire colour spectrum, not 3.
If you wanna play the workaround game, point your finger towards both panels; they merely have a single-color OLED backlight as opposed to the RGB OLEDs we have in our phones.
Me too. For now it seems like a workaround of LG's tech, and I don't see any reasons why it is superior.

i think this is desperate and ill-advised. ill-advised because of the overabundance of high frequency light (blue), people are already finding it necessary to wear yellow filter glasses for computer monitors. add to the fact that most households to purhase will have children with far more sensitive eyes. we will go back in time to when CRT tv's emitted microwaves, forcing people to sit at least six feet away.
this is desperate because of the other players in the field being more advanced.

Lol, no doubt.
Honestly, they gave up on Oled because LG wrecked them big time with life span. Seems that this sort of Filtering thing is a gimmick so Sammy can say they have Oled TV's too since quantum dot isn't taking off.
Myself as a consumer just wants SUHD tv's that are not in the premium price bracket, oh ya and standard 120Hz or adaptive refresh rates. It's unfortunate that TV's lack innovation such that those options are mostly with held, not due to accessibility, but just to form a pricing hierarchy.
Is it too much to give the consume what they want so they can spend their money instead of more of the same .... gimmicks?
.....along with a Quantum hole in consumers wallets. :p

Lol
I wonder when are they going to release computer screens with that technology.
Maybe if/when OLED burn in problem is resolved. And yes, it is a real problem, despite what some who are trying to sweep it under the rug are claiming. This issue is even more relevant for PC monitors because you have a lot of static elements which might be visible for hours on end.
