Yes, it's not OLED mis-spelt..

Samsung today announced an all-new line of televisions it calls QLED, and while the picture quality has gotten better, its the new series’ design that makes the biggest difference this year.
QLED replaces Samsung’s two-year-old SUHD line as the company’s most premium TV line, and it includes several meaningful upgrades. QLED offers better viewing angles, brighter high dynamic range (HDR) performance, and increased color production (100% of the DCI P3 color space), with claimed improvements to black levels as well.
The design has improved as well — you can now mount a Samsung QLED TV smack up against your wall. With Samsung’s proprietary mounting system, its Q9, Q8, and Q7 QLED TVs can be mounted flush, making the TV look more like a piece of art than a television. If wall mounting isn’t the plan, Samsung offers two types of table-top stands with modern styling, crafted from aluminum and stainless steel. An easel-style floor stand offers an uber-modern option for those who want their TV to take center stage in their room.
If wall mounted, Samsung’s QLED TVs offer nearly invisible cable management. Thanks to a new fiber-optic system, the cable that delivers the TV’s video signal looks like nearly as thin as a strand of fishing wire, and essentially disappears against a wall. Power must still be provided to the display, but many modern homes offer a power outlet right next to the TV’s location.
But is QLED a radically different kind of TV technology? No, not exactly. Videophiles who follow TV development may have been hoping for an emissive, non-organic alternative to OLED TVs, which can actually turn off each individual pixel to allow for perfect black levels. QLED is not such a technology … yet … but it’s still a notable leap forward in TV tech, and worth paying attention to this year.
To be sure, Samsung is very much making a strong play for your attention, and its new QLED TVs earn that. We look forward to evaluating these new TVs and letting you know how they perform in our review process.

What is QLED:
http://www.whathifi.com/advice/qled-tv-technology

QLED stands for quantum dot light emitting diodes. It aims to be the next step on from OLED, which in turn, tends to deliver superior performance compared to LCD.

At the moment, only LG and Panasonic sell OLED TVs in the UK, though Sony is likely to launch its own range at CES 2017. OLED tellies are much slimmer than LCD or plasma sets, with much wider viewing angles and infinite contrast ratios.

QLED promises to improve picture quality yet further without sacrificing the deep blacks of OLED sets.

How does QLED work?
It works using quantum dots. This technology itself isn't new - Samsung's SUHD TVs use quantum dots, for example - but QLED uses it in a new and interesting way.

Quantum dots are microscopic molecules that, when hit by light, emit their own coloured light. Which colour they emit depends on their size - larger ones give off light in the red end of the spectrum, and smaller ones in the blue end. (They're only nanometers in size, which is a fraction of the width of a human hair. So when we say "larger", it's all relative.)

Current TVs use photoluminescent quantum dots, whereas QLED TVs will use electroluminescent ones. Basically, instead of requiring the light from an LED in order to light up (as photoluminescent quantum dots do), electroluminescent ones use directly supplied electrons to generate light.

This lets the TV light up and turn off individual pixels, just like an OLED set, making for the same infinite contrast ratio.

Quantum dots supposedly give off incredibly bright, vibrant and diverse colours, making them well suited to showing off HDR content. And, crucially, they're reckoned to be a more cost-effective technology than OLED.

In other words, a QLED set could be able to match or improve on the picture quality offered by OLED, and at a cheaper price. That's the theory, at least.

As the technology currently stands, quantum dots are a mixed bag. In our review of the quantum dot-enabled Samsung UE65KS9000, for example, we noted that the black levels could go deeper, but that there was a slight issue with backlight banding. But overall, the set was superb, delivering one of the most lifelike pictures we've seen from an LCD panel.

It's worth remembering this is only the start for quantum dot technology. Based on our experience so far, the future looks bright. Literally.

This is my take.....

OLED gives the darkest black.

Quantum Dot gives the brightest White.

I bought the OLED.

Does this mean that whites will look like grey in OLED and blacks will look like grey in QD? ???

The brightness allows Samsung SUHD TVs to reach the full HDR specs. It won't be ideal for dark movies, but may give HDR movies some boost. I have a Samsung UHD without QD and Netflix HDR does seem a little dull... Seem to prefer regular Netflix 4K

The 2018 series seems a lot more promising..
But the price gets very close to OLED ..

Saw the Q7 recently. Looks really good. Able to differentiate the dark scenes better (i.e. less flat and with decent details)...

was this in a electronics outlet scenario?

Hi, yes. Are these ‘salesman’ gimmicks to push for certain brands?

Even the same electronic store at different locations, different salesman tell me different things...

There's a side by side comparison with the LG B7 at around min 6..
The Samsung actually looks nicer

The Q9FN vs the LG C8
It's a tough call..

not gimmick, just environmental factor.  electrical stores are typically very brightly lit, which will make the blacks on an OLED look crushed (because the near-black levels on OLED are much closer to 0 nits than the same on LED).

Was reading a review for a Korean mid-range LCD LED TV.

“Shadow detail isn’t great, either. Dark clothing or hair can appear a bit flat, especially in scenes split with bright sections. Local dimming could also be better, since you’ll occasionally notice some clouding effects. Sometimes this bleeds from the picture into the black bars at the top and bottom. The lighting certainly isn’t as uniform as I’d like.”

I encountered 2 salesperson highlighting this (black hair a bit flat), as well.

Could it be that if the TV operates in a dimmer environment, this issue will be less obvious?
