      The enclosed copy and paste from an article I was browsing makes for interesting reading. I can't post link as it's behind a pay wall. Talk about not knowing which way to jump.

      Personally I wouldn't even touch an Oled for another 2-3 years anyway . Just seems to be so many problems

      Not least because of the prices. :eek: I hadn't really thought much about Quantum Dot though. Who currently is using this apart from Samsung?

      Does anyone really now what a true QLED screen is?
      This technology is not available today in consumers tv and will not be for some time.
      OLED screens is the way forward for now.
      All other screens are LCD with LED backlight, and that's it.
      LCD screen tech is very old now.
      The QLED termelogy used by Samsung is a marketing scam, ( it's an LCD screen with LED creating the light) however it's working well as most buyers are ignorant.

      So what is the article talking about then? It says that if some tech issues can be ironed out then QLED shipments could account for 100% of the market by 2021. That's only 4 years from now.

      If you are saying something different to the article then you should flesh out your assessment in a similar way to the QLED piece.

      Quantum Dot technology was used in Sony TV's under the "Triluminous" banner since at least 2013 to improve colour. My first 4k TV the KD-65X9005A had it and I bought that in 2013. Samsung's current QLED's are a development of the same thing.
      True QLED is a self light emitting technology and is not available yet.

      The industry expects that it will take more than 5 years to mass-produce QLED displays.

      So by then id imagine Oled to be cheaper and more of a foot hole in the market place and few more in the market place .....

      Not at all since it's very limited in brightness, Micro-LED is the future and will be released in 4-5 years.

      With new tech it all brings issues etc
      You will never achieve perfection .........
      But will get closer .

      If i never bought in to buying plasma with again issues
      I would of not enjoyed 9 plus years of enjoyment and viewing on my Monitor and still gives an Excellent Picture 9 years later

      Oled now what 4- 5 years old give it another 4 years will sort out pic issues .

      But by then a new tech will be out Qled / dot ?
      And oled will be like Plasma as such .

      By then your eyes would of faded due to age and you wont tell the diff ;)

      Get whats the best out now and Enjoy with the inperfections .

      I Have :)

      I don’t think it’ll be that clear cut and it won’t be a rerun of plasma vs LCD.
      OLED displays are here for the long-haul and 2017 has shown they are now dominating high-end sales and I don’t see that changing anytime soon.
      Also, we’ve yet to see the full potential and commercialisation of OLED’s ability to be both flexible and transparent (for example, transparent wallpaper OLED display on the inside of shop windows offering AR interaction to customers, a trick micro-LED is unlikely to do).

      I think OLED is currently the best quality for TV/Movie viewing and I don't think that will change for a couple of years unless someone does a high resolution FALD (128K or more array elements for eg) behind an QD-LCD which may on average be comparable.

      It would seem however that QD variations have an interesting roadmap ahead of them - perhaps high resolution FALD backlighting eventually and then eventually per-pixel electro-emissive elements in 4-5 years (ie no more backlight at all). Once it gets to that stage then it will have functional parity with OLED for TV use and probably be much more robust (no IR/Burn issues, higher brightness due to higher max per element operating temps etc).

      OLED may end up instead spearheading flexible and/or transparent displays instead and perhaps yield a new portable device form factor and fall out of general TV use perhaps in 5-10 years unless it can be made a lot cheaper to make and generally far more robust. If nothing significant changes with OLED tech, I wouldn't be surprised to see LG starting to drop it for TV panels within about 5 years from now, or maybe it will become the budget TV tech if inkjet OLED printing can indeed make them very cheap to mass produce.

      All the article is saying is that LCDs will remain a competitive choice in the near future and we shouldn't expect the transition to self-emitting displays like OLED to be a rapid all-out affair like previous technology transitions such as CRT to LCD.

      Basically, just stating the obvious. Presumably the original intent was to reassure investors in LCD, but I guess it's been repackaged with a clickbait title and summary and spread more widely.

      So what is this article discussing then. You say QLED is not available yet the article quotes the following -
      We are almost into 2018 and the above states 2016 - 2021. I'm now completely confused. As someone that only changes their TVs on an infrequent basis the wise move then must be to sit and do nothing for the foreseeable future.

      My reading of this article is that QLED is the future and will ultimately win out, not OLED, or am I completely off the radar with this?

      Hi

      It's all marketing these days anyway. However QLED is not a scam. Yes it is an LCD screen, it has a 10 bit panel usually on most models which is good, and uses Quantum dots hence the Q. This Quantum dot as Samsung calls it is used by the backlight in order to produce a better source of white, this is one of the things that allows the panel to display a much larger colour gamut, which can be measured and confirmed.

      We bought a QLED TV (no way were we going to go OLED and be constantly worried about the screen wearing down and burn in and having to baby sit it) and this replaced an older Panasonic LCD TV and the difference was jaw dropping, and still is, even after 2 months we are amazed at the difference and this is just on normal HD footage.

      The next step for QLED/LCD panels are the "Q" dots replace the filters on the front of the glass, so the back light will just be UV or blue, and each pixel then becomes emissive just like OLED. The LCD display will let through a varying amount of UV or Blue light from the backlight, and this excites the dots to produce either red green or blue of varying brightness. The benefits are a huge step up in efficiency and so brightness along with wide viewing angles. Because these dots are not organic, the problems of uneven wearing (burn in) are eliminated. These panels are also easier to manufacture as the quantum dots are stable and easily pass through the LCD manufacturing processes unharmed, unlike OLED which is very fragile and needs special treatment. It's called "Organic" LED for a reason, because like anything organic, it decay and breaks down and has a limited shelf life.

      OLED TVs are it seems a stop gap until this technology arrives in a few years time. They are fundamentally flawed as they just don't last any length of time, and start to wear out due to the organic nature of them. This is why we don't see OLED used on computer monitors, as after a matter of a few weeks all the UI elements will be burnt in and it would ruin their reputation completely. They also can't be driven very bright as there is a limit to how much current you can get to each pixel and how hard those tiny pixels can be driven before being destroyed.

      Regards

      Phil

      Not forgetting HDR 10+, HLG, Dolby Vision, 8k. OLED is the least of your problems ;). Its all outdated before it left the warehouse. Buy a TV you like and just enjoy it

      Led tv are flawed as well the amount that are returned with pixels gone and light bleed issues etc

      They both have issues

      If i was purchasing a new screen it would be hands down Oled
      As id want the best Picture Quality possible .
      Even with issues .
      It has a 6 year gtee so any issues that arise send it back .

      And as for screen burn ive had a plasma Monitor and still going strong .
      And the only thing that beats it is Oled picture wise .

      I could not go lcd as had two .

      From DSCC's site

      "Mr. Young founded DisplaySearch, the leading flat panel display market research, consulting and events firm, in 1996 and ran it for 12 years before selling it to The NPD Group and joining Samsung LCD as VP of New Market Creation."

      Not in any way suggesting they're shills or that they're tailoring research to fit the audience but I'd be a little bit wary of any output purporting to promote QLED at a QLED conference from an ex (or is he current?) Samsung exec.

      :)

      You didn't link the whole thing, but the quoted extract only talks about the near future of five years time and says nothing about diminishing OLED production or LCD achieving sufficient technological advantage to drive down OLED sales.

      It says 'QLED' could account for 100% of the LCD TV market if production ramps up well. That's no great surprise given they're pretty much a drop in replacement for the current colour filters in LCDs.

      OLED could be a short lived technology if one of the other similar self-emitting display technologies (QD LED, Micro LED) ends up surpassing it and has more potential for future development.

      It may be that the impetus from HDR for local dimming systems on LCDs develops them back into good competition at the mid-high end too. There are advantages to transmissive displays over emissive ones.

      Yeah, it'd be like making houses out of wood or expensive shoes out of leather. Who on earth would choose such perishable organic materials over more durable synthetics at that price?

      Categorisations that broad are meaningless. Without understanding the specific technology behind OLED it's impossible to estimate how much the longevity will improve with refinement. It could easily end up that's there's no practical difference for home TV use.

      Hi

      A Samsung Q7F QLED. I didn't really believe the marketing on QLED, and bought it based on reviews and that it was a true 10-bit panel and UHD Premium certified to get some reassurance the spin about the picture quality had something to go some why to back it up. The One Box setup was also pretty convenient meaning the TV itself is pretty slim. It was only afterwards I've learnt more about QLED being something more than just a branding exercise.

      Regards

      Phil

      You do realise that virtually everything is going Oled as such !

      Oled iWatch Apple
      Oled iphone 10 Apple
      Oled rear car lenses ( Mercedes Benz ) more to follow
      Oled Surgery screen ( coming soon )
      Oled samsung phones for a few years amongst many other manfactures
      Oled panasonic Tv
      Oled Sony tv
      Oled LG Tv
      Oled Fitness watches numerous manufactures .....
      Oled watches
      Oled screens on cars w.t.s .

      So your not going to buy in to any products that are Oled based then because of Burn in and issues ?

      I'll second that. The first LG 65B7 I received was unacceptable though. Bad vertical banding in grey & a yellow tint to whites on the left hand side of the screen. So if you get one and it isn't perfect, send it back. The 5 year warrantee should make sure its ok until the next best thing comes along. :)

      And to think before this new generation of TVs came along we kept our previous CRT TVs for 20 and 23 years respectively. :eek:

      What price progress. :rolleyes:

      OLED is the rapidly arriving near-future. As was pointed out above mobile displays are mostly moving towards OLED (either the Samsung or LG variety). 90% of the top-end phones and TVs use OLED panels.

      4K OLED TV prices tumbled this year, and will continue to do so as manufacturing costs for OLED panels match LCD by 2020/2021. This figure is based on a projection by Display supply chain consultants.

      You can read all about OLED's growth (both recorded and expected) here :DSCC Reports Quarterly OLED Revenues

      Micro-Led is currently at the prototype stage and by no means a sure thing. It may or may not reach market. Sony and Samsung both have been able to make them but only in very large sizes. (e.g: CLEDIS and 150incher rumoured for CES 2018). Sony did showcase a 55inch micro-led tv in 2012 but has not said a word since. What this tells you is 1) they are not able to make a consumer-size micro-led display yet. 2) They are not able to make it at an economical price yet.

      Once Samsung achieves a consumer sized (50-70inch) , mass-producible emissive QLED or micro-LED TV (this will not happen in the next 3 years) , we will still need to wait 3-5 years for the price to come down to something reasonable.

      by way of example, the first widely available OLED TVs by LG in 2013, the LG 55EA9800, debuted at $15000 before dropping to $10,000. 4 years later you can get an equivalent sized panel for about $1500 (which for many consumers is still not a 'mainstream' price).

      I got an Lg Oled about 2 months ago and I've got to say it's the best TV I've had I've been swapping TVs every 2-3 years and my last 3 have been Samsung led.
      The last 2 I just didn't think we're much of an improvement on what I'd had before and I felt like I probably shouldn't have bothered upgrading.
      The LG Oled on the other hand has consistently had me saying to myself this was a bloody good buy, granted it was expensive
      but it feels like money well spent.
      I would like to add a day after setting it up I stumbled across the burn in and screen retention issues threads on here, this obviously did my head in as I'm an avid gamer and as a htpc man the windows icons are static on my screen a lot I'm glad to say I've had no problem whatsoever, so in conclusion in my experience as it stands Oled is the future.

      QLED is just a branding of Samsungs current high end QD LCD TVs. I think QDLED is the generic name. The chemical QD technology comes from elsewhere. I think eventually if the promise of electro-emissive QD tech can be made at a decent price point and its as good as expected, then that may replace OLED in TVs - but I think that is still several years away.
