      While it sort of makes sense to have a simple monochrome OLED array illuminating an LCD quantum dot enhanced panel, this is Samsung doing everything it can NOT to acknowledge LG got it right with OLED.

      It sounds like strapping wings and a jet engine to a hot air balloon instead of building an aeroplane.

      Damnit Samsung, just make an RGB OLED panel or get micro LED to market fast. If you can't do either of those, then just eat humble pie and buy in some WOLED panels from LG like everyone else.

      I fear if Samsung don't do one of those things, they'll be kissing their TV market share goodbye to the Chinese in the next 3-5 years.

      after Hisense it's around samsung to get into Oled screens!
      now we can say that list of manufacturers tv is complete, all for the Oled!

      Will this counter the current OLED tech brightness limits?

      I thought blue OLED had the worst lifetime of the lot, so using blue OLED exclusively as a backlight seems like a really good way to get burn in. Be interesting to see what their mitigation strategies are (though it sounds like they're a way from being able to commercialise this yet)

      Yes, it sounds odd doesn't it. Didn't LG get around this problem by filtering White OLED's to get blue? It's probably a patent thing that Samsung can't copy.

      The more I think about this, the more it sounds like Samsung is just firing out propaganda to make it sound like they have the future of TV technology at hand. But all these half baked scatter gun boasts and hype scream of desperation to me.

      Under the cover of OLED, LG don't have to shout about stuff that doesn't exist yet, but you can bet they're working on other stuff too.

      Wait, so Samsung does everything it can to make their TV's appear to be anything but LCD.

      "LED" technology (LED as source light}
      Curved (to match the 1st OLED TV's)
      QLED (with a rather ill defined "Q")
      And now this. (It's an OLED screen!!......But with an LCD screen in front of it)

      It's an odd mix, but who knows, it might work??!

      I think this is probably closest to the truth sadly. They will at some stage actually have to produce a feasible product that can be mass-produced at a relevant price to current OLED prices ... and that doesn't look like it is going to happen this year.

      As far as I am aware they still haven't detailed their 2018 range yet - no model numbers, no specs, no pricing and no availability. You would think that would be their main aim right now but seemingly not ...

      Lets assume the rumour is true..

      What is the business case for this technology ? They promised to deliver microled next year, claim they are continuing with LED/FALD that they've long claimed to be the best tech..

      So, if they were going to try something else, like this, where does it sit ?

      Is microled going to be too expensive or unavailable in smaller sizes (say under 80") ?
      Or as Jules says, is this tacit acknowledgement that the OLEDs are stealing market share ?
      Maybe they think they can do this cheaper than FALD that equals an OLED screen ?
      If the results of the research are positive will they abandon LED for part of the product range ?

      Will be interesting to see what comes of it (if anything)..

      Good points.

      With Samsungs pricing, they will have to be careful with their top LCD models. I dont think Samsung has an FALD line though do they? FALD is great with enough zones but that can still be very pricey so an OLED screen might not be too much of leap.

      I really don't think mircoLED is going to be a much of thing for a couple of years AT LEAST and nothing below what? 75"

      Of course this might just be like the Apple rumours. Some perfectly normal research might be dropped and then someone picks up on it and it goes into ballistic headlines. It could be it was this or microLED and Samsung chose micro. We all know how they despise LG and their OLED progression, it could be a step too far into admission OLED is a great technology.

      I don't see an issue with Samsung exploring other options besides OLED. OLED isn't without it flaws afterall, yet so many see it as an 'end game' in TV technology.

      Crack on Samsung.

      It does say the translation is a little confused. It would make more sense if it actually says an all blue OLED array with quatum dots to change sub pixels to red and green to provide RGB pixels. In effect it would be like LG OLED, but with light converted rather than blocked, so potentially brighter.

      I won't be buying an OLED TV to go in my sunny house. So LG and their OLED aren't catering for me. I'm very interested in any none OLED tech that's coming over the horizon.

      Combined Samsung OLED and quantum-dot for new displays?
      Blue OLEDs as light source
      Blue OLEDs to be used instead of LEDs as the light source. While emit blue light directly through the diode, quantum-dot color filters allows Red and green colours. Color reproduction will thereby significantly and lie beyond the DCI-P3 color room. The advantages of OLED technology would completely cut through. QD-OLED TV had a thinner display and would be correspondingly easier. Other advantages would be the improved viewing angle, color reproduction and increase the contrast.
      According to the source, first prototypes of QD-OLED displays with 55 and 65 inchesshould be in internal tests. The commercial exploitation of the technology is still not possible, because there are problems with the OLED light source. The emitted blue light ensures distortion of shades. The problem should leave but get grip, requires but little more attention of Samsung's engineers.
      Samsung TV lineup 2018 not yet known
      We're definitely curious, what holds Samsung for the year 2018. The TV lineup for 2018 was only being addressed. Which devices are really interesting for the European market, which devices there will be, as well as information on facilities, availability and prices are still not communicated. We hope to see some more clarity from the exclusive Samsung event on February 27, 2018.

      I hope this is true, we need the competition to push the technology further, OLED, as great as is it is becoming stale already as we're reaching the limits of this tech.

      I watch everything in a completely dark room. If ever I turn the lights on the immersion drops to pretty much zero.

      I'm intrigued by the technical options that there might be here.
      It looks like QD-OLED could be one of at least two things:
      • One blue emitter per pixel, with red and green quantum dots each covering around a third of it, so each LED is emitting red, green and its own native blue. The RGB signal modulation is created by the LCD, so each pixel-sized emitter sits behind three LCD 'shutters' for the red, green and blue illumination.
      • Or ... a large OLED emitter for several pixels, each with a matrix of RGB/RGB/RGB filters laid on it, behind the LCD plane. Dimming that one emitter would dim several pixels at the same time, but that has to be better than the handful of dimming zones we have at the moment with conventional LED/LCD panels.
      So fabrication at the emitter level becomes much easier because its only one third (or less) of the density of the LG OLED panels. Connection is much easier because you only need a connection per pixel (at worst) or per dimming block of pixels, not one per sub-pixel.
      But for me this raises two questions:
      • Now that economic OLED fabrication at the 'one emitter per sub-pixel' is quite possible - as LG have proved - why go down this route at all? OLED is an opportunity to get rid of the LCD plane completely, so we 'see' all the light that is being emitted, not just one third of it. Is this all about Samsung seeing Quantum Dot as the holy grail, and hoping to prove they were right all along?
      • If they were to use larger LEDs covering several pixels, why would they need microscopic OLEDs in the first place? Larger conventional LEDs ought to be quite possible, with the benefits over OLEDs that they would bring to the table.

      The point raised earlier about blue OLED aging not is very pertinent.

      What is the point of leaving in one of OLEDS weaker aspects whilst retaining the weaknesses of an LCD panel.

      Uniformity over the life time of the panel would be even more of an problem than it is now.

      Responding to Jules, I guess the logic is perhaps it's easier to use blue to drive Quantum Dots, and, as all colours are being driven by the same blue LED, at least they will fade (gracefully?) together as the emitter ages - which would not be true of separate prime colour emitters.

      Samsung have denied these reports: Yonhapnews Agency - Mobile

      Samsung's abandonment of OLED development a few years back was a grave mistake imo, especially given their expertise in producing smaller form factor OLED screens for smartphones and tablets. LG Display's move to 10.5G fabrication next year and the eventual (imminent?) entry of the deep pocketed Chinese SOE's into the OLED market will only put Samsung further behind the competition in the highly competitive television market.

      MicroLED looks almost too good to be true. As impressive as the demos were I suspect that it's little more than 'vapourware'.

      I'd be very surprised if your room was brighter than a showroom. If you are planning on watching a lot of HDR movies in the middle of the afternoon then OLED wouldn't give the optimal punch for the highlights, but OLEDs are plenty bright enough. You won't need to go to max brightness.

      Put it this way, their a tonne brighter than most (probably any) tvs were a few years ago, and I'm sure whatever tv you had then was perfectly watchable.

      At worst, if you were concerned about it you could buy from somewhere like Costco or JL and return it if it isn't bright enough.

      Obviously the QD layer in this case would be the Photo emissive layer that was the next stage for the development schedule. It doesn't need a red/green filter as it uses the light photon energy to change the blue to Red or Green as needed - blue just passes straight through. The advantage of this is that all the light energy is used where as with other systems, some of that energy is filtered out. This gives the ability to hit much higher peak brightness levels without increasing the energy consumption as all that 'energy' that is filtered out is no longer wasted.

      The rumour may well of arisen from Nanosys who stated that QD Photo emissive layers were suitable to be applied to OLEDs as well as LCD's which may well have ended up being twisted to say that Samsung were working on it as Samsung are a major shareholder of Nanosys.

      I would be surprised as it probably wouldn't make sense for Samsung. The Photo emissive QD layer can be used with LCDs and as Samsung are looking to MicroLED. MicroLED can be used to significantly increase the dimming zones by having an incredibly high number of these in an array. By making these 'tiles' with a single 'blue' Micro LED, they can improve and perfect the manufacturing process. By using tiles, they also wouldn't necessarily have to make different densities either - the bigger the TV, the more MicroLEDs in the array although the size of each zone and 'density' of MicroLEDs remains the same. Obviously the pixel count that each zone has decreases as the size of the TV's increase. These TV's may not be quite as 'perfect' as an OLED but could still have much better performance than the current best LCD (ZD9) and a MUCH greater Colour Volume too so may not need to tome map at all.

      MicroLED is as good as it sounds, it is just currently hard to make. Currently Apple are the closest to releasing MicroLED displays and have been gobbling up anyone with MicroLED patents. It will be interesting to see if Apple only use their own microLED tech for their products or if they launch a true Apple TV instead of just a box.

      Samsung only recently got into MicroLED and their pixel size is still far too large for smaller televisions and phones.
