Samsung will show 'OLED' TV based on quantum dots
Yes, that news title is a bit of a paradox eh? But is the claim really, perhaps OLED quality would describe it better. At the CES, the manufacturer wants to show a TV in which an organic luminescent layer based on quantum dots that provides high-color and high-contrast images.
Samsung apparently wants to rely again on OLEDs: The Korean display specialist uses a blue-glowing organic layer to stimulate quantum dots that produce red and green pixels from the blue light. The advantage over the previous LCD TVs with quantum dots: a viewpoint independent, high-contrast representation. The advantage over previous OLED TVs: extremely rich colors. In addition, the quantum dot OLED combination (QD-OLED) works in an energy-efficient way, as the complete light from the blue "OLED backlight" is used here for image generation. In LCDs, on the other hand, two-thirds of the light is blocked at the color filters and is therefore lost to the display.
The QD OLEDs also require a yellow reflector, which prevents the ambient light from exciting the quantum dots and emitting them, even though the underlying organic layer does not light up. The quantum dots for the red and green subpixels are printed in the pixel grid, while the organic luminescent layer is applied over a large area.
It consists of various organic layers, which can, however, be vapor-deposited cost-effectively and unstructured by means of CVD (Chemical Vapor Deposition) methods. As a result, no metal mask has to be precisely positioned and moved over the large TV substrates in production and, unlike the techniques used for smartphones, no expensive organic material is lost when the luminous layer is applied. Both of these factors led Samsung, among other things, to refrain from developing its 2013 OLED TV with a pixel matrix of red, green and blue organic light dots.

According to Digitimes, Samsung wants to redesign a generation 8 LCD factory for OLED fab with oxide TFT substrates. Thus, the manufacturer could go relatively quickly into series production. For example, the first samples will be available by mid-2019 and then run 25,000 substrates per month - if six (perfect) TV screens are cut from each substrate, that would be 150,000 TVs per month. By 2020, capacity will be doubled. However, Samsung still has a few technical hurdles to overcome. Samsung plans to apply the organic material to Canon coating machines and print the quantum material on Kateeva machines. What will cost such a QD OLED TV in the end, is still open. The goal can only be to not be significantly above the current OLED prices.

interesting,
maybe that is the future, or maybe the micro-led technology
Bad times for buying a new TV, too many options. I hope my actual Panasonic Plasma keeps ok for more time
Same
teevees are putting consumers in a quandry right now, and (if I may pontificate) is kinda the position we began with when the whole '3D' crap started ten years ago.

Bought my 60" zt60 when they were on clearance in '13 or '14. 5 year square trade, but it's still going strong and looks better than nearly all 4k TV's(sansOLED) at the right viewing distance. Sports on a plasma is heaven.

Either way its done these will not be cheaper than the relative OLED's released at the time of these. Just due to the added manufacturing processes it'll be much more expensive than competing options.
Loving my 2017 LG OLED and Vizio's 2018 100 zoned backlit home theater TV.
In about three years or so when the proverbial dust settles ill be ready for another upgrade or two and it should be just in time for my new consoles and PC build!!
Still waiting for all teams (Red, Blue and Green) to get their heads outta their arses so as we can have legit PC competition once again. As opposed to this nickle and diming the consumers with hardware pushes from yesteryear in the form of less capable hardware all together. Innovation regarding hardware should never be pushed backwards to the consumer.
Sales I guess......why I'll never want to deal with it....

I agree with sports content on Plasma. Do you have burn in?

There is a difference between burn in and image retention.

The issue with plasmas is that they have a half-life of about 10 years - meaning they lost half their brightness approximately every 10 years. The change is so gradual that most people don't notice, but I know that my 2009 Panasonic P50 was getting pretty bad as far as viewability on bright summer days when it died a couple months back.
I replaced it with a 2017 LG OLED and man, I would never want to go back. Sharpness is the big difference - plasma tends to be a bit "soft" due to cell bleed, but the color vibrancy is much better, and HDR looks incredible (unlike on the LG 70" LCD in my HT, where it's barely notable, probably because of the lack of local dimming).

Doubt the got sony to license them the tech,
so its maybe based on their phone screens.
But also shows how "not so good" their tvs are, or they wouldn't feel the need to improve on things like viewing angle..

I thought I read that OLED is suppose to remove the static refresh rate. Has that been figured out?

If OLED displays don't hit the sub-$1k price range and offer more size options before micro-LED launches I don't think manufacturers will bother with OLED long after.

I think you misunderstand. The last several years of plasmas had brightness half-lives of 100,000 hours. that's over 11 years of being on 24/7.
I have a Panasonic ST30 that has been my primary television since 2011. I barely have 10k hours on it, which is still several hours per day. I also have calibration tools and I tweak it occasionally, and the maximum luminance hasn't gone down by a measurable amount in that time period. I will have long since replaced this television before there is a perceptible drop in luminance.
Also, backlights on LCD televisions are actually much worse than OLED/Plasma in terms of long-term reliability.

This is supposed to be cheaper than the microled. The reason for this is that the luminofor that they apply over the blue oled layer is chemically deposited, so you can cover a large area at once and it costs the same money to apply it on any size screen.
