Samsung's quantum dot tech might be its path to OLED TV relevance
Samsung Quantum Dot TV

Samsung knows a thing or two about OLED displays – it’s arguably the market leader when it comes to OLEDs for smartphones, with beautiful screens on its own devices and outsourced manufacturing to a bunch of other phone-makers. 

In terms of TVs, though, it’s had a little bit more trouble in recent years. The South Korean firm has made no secret of the fact that it wants to make high-quality LED televisions for the mass market, but has had difficulty in scaling production effectively.

Rather than going with the more well-known OLED technology, Samsung has been ploughing its own trough with QLED displays, which, while still very much good, haven’t been quite as impressive as some OLED competitors. 

Samsung’s not deterred, though, committing to build a plant, completed in 2025, to just to make its QLED TVs at a scale that becomes cost-effective. It may now have had a bit of a breakthrough, too.

Two of its researchers, Dr. Yu-Ho Won and Dr. Eunjoo Jang, have published a paper in scientific journal Nature detailing quantum-dot LED technology they’ve created that uses less hazardous materials and has a practical lifetime of up to a million hours. That’s the sort of useable life cycle that spells “commercially viable”. 

Lord knows we can’t have enough acronyms, so it looks like this tech will be called “QD-LED”, and Samsung seems to be all-in on the technology. However, given that we’re only at the stage of scientific studies for this new tech, it remains to be seen how long it will actually take for these fresh types of TV to actually hit the market.

4K is here to stay, says experts.

CES 2017, the consumer electronics trade show held annually in Las Vegas, is about to begin and as usual, the event will be a showcase of what technology has to offer for us in the new year.

TV technology is one of the spectacles expected to make a splash in this year’s CES. This includes the 4K Ultra HD TVs that are expected to exceed the TV displays we saw in 2016.

You can expect big players such as Samsung, LG, Sony, and Panasonic to hold down the fort, while emerging stars such as Hisense, TLC, and LeEco will make their presence felt with their flashy TV displays.


There is no doubt about it: 4K display is here to stay, says Stephan Jukic of 4k.com Only a couple of years ago, tech watchers dismissed this display technology, but it has become the standard in all smart TV units of today.

All of the major TV manufacturers such as Samsung, Sony, Vizio, and LG are releasing their own versions of a 4K resolution TV, ranging from high-end units to affordable ones.

In 2016, the 4K technology put the 1080p in a corner. In 2017, you can expect the 4K Ultra HD to completely wipe it out of the picture, especially now that 4K content is getting to be more accessible, thanks to Netflix, Amazon, and Ultra HD Blu-Ray discs. 4K Ultra HD will provide TV viewers with an experience that is four times sharper than the one from a standard HD.


Another trend to watch out for is the high dynamic range HDR. This will be a must-have feature for 4K TVs that are in the upper midrange to high end.

HDR provides great contrast between the lightest and darkest images, and also produces a wider range of colors so that your TV can create a more vivid image.


CES will also showcase TVs with improved color performance due to quantum dot technology, beginning with the Samsung QLED TV. We can also expect TVs with remarkable peak brightness.

Jukic is looking forward to one model in particular: the OLED 4K HDR TVs from LG.

Those that come out after CES 2017 will “ramp up their peak brightness even further to some stunning new levels that were previously unheard of for OLED display,” he writes.

If even the 2016 LG B6 — the brand’s brightest OLED TV for 2016 — could manage to hit over 700 nits of peak brightness most SDR LCD TVs can’t even manage 400, then it will be exciting to see what the best that the 2017 models can do is, Jukic adds.

If you are buying a new TV this year, CES 2017 will surely have plenty to offer.
