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.

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.
What.. Why does the base light frequency matter, you're filtering it to create other frequencies (colours) anyway..?
Desperate? Having more competition in the OLED market is desperate, considering how few players there are? Good lord.
Literally nothing you said makes any sense.
Is it too much to give the consume what they want so they can spend their money instead of more of the same .... gimmicks?
Gimmicks? Have you ever seen an OLED screen?

It should cut costs as LG won't be the only option on the market.
.....along with a Quantum hole in consumers wallets. :p

yes i have an oled screen from LG.
it is the best tv i've ever owned.
red and green filters do little to block the overdriven (if Samsung's history is noticed) blue.
period
if you're going to throw darts at least be accurate and knowledgeable about the topic. i've built CRT monitors from parts and worked for the company that made the best reviewed TV ever made for over 16 years.
but ok, knock yourself out

oled and plasma *panels* are *the only* technologies with 100% light transmission and control *per pixel*.
LCD panels are *screens* by definition.
whatever light that is not filtered through *is greater* than what gel/color/paint on the inside can absorb and results in "bleeding", "prismatic effects", terrible color balance - universally too fake white with no control over pitch - even in "local dimming" lcds.
think of it as light pollution...like why there are no cutting edge observatories within hundreds of miles from cities.

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.

Uh, all LG OLED TV's do color filtering... also their advantage isn't lifespan, it's owning the patent on the white OLED - which they bought from Kodak. AMOLED tech doesn't scale to TV sizes so Samsung is stuck coming up with a different solution.
