Samsung researchers found a way for QLED technology to not use backlights

Samsung researchers found a way for QLED technology to not use backlights

In their ongoing effort to get closer to OLED technology (which is patented by LG) Samsung researchers have found a way to make the company's QPLED technology behave more like OLEDs.

So the new development would allow for QLEDS that do not require a backlight, (which all current Samsung still have) as they cannot use OLED technology due to its patent. The new study shows that each pixel provides its own lighting, just like with OLED screens. So that would be the holy grail for Samsung, true quantum dot LED panels that promise self-emissive indium phosphide diodes.

-- Samsung -- 

A duo of researchers and fellows at Samsung Electronics have, in an industry-first, proved the potential of Quantum dot light-emitting diodes (QLEDs) for commercial purposes in a new study. On November 27 (London), this study on the commercialization of QLEDs was published by Nature, the world’s leading multidisciplinary science journal. The authors of this groundbreaking project are Dr. Eunjoo Jang, Samsung Fellow, and Dr. Yu-Ho Won, a Principal Researcher at the Samsung Advanced Institute of Technology. By improving the structure of Quantum Dots, the team managed to hugely improve quantum efficiency, as well as extend the lifetime of the QLED element. The team found, at the conclusion of their study, that their method had improved quantum efficiency by 21.4% and increased the QLED lifetime to a million hours.

“Thanks to Samsung’s distinctive core material technology, we were able to work towards exploring the potentials of next-generation displays,” noted Dr. Jang. “Going forward, we are looking to expand the range of development of ecofriendly displays by adopting Quantum Dots in new structures.” “This study has enabled the production of Quantum Dots with high efficiency regardless of shell thickness by providing a better understanding of the mechanism that produces Quantum Dots,” added Dr. Won.

In 2015, Samsung launched its Cadmium-free (Cd-free) Quantum Dot TV and continues to lead the development of next generation eco-friendly displays, having obtained over 170 patents on element structure to this end.

Wow.. future Samsung QLEDs will not be anything near the past if I read this right this would entail.. .

A "QLED panel" vs QLED pixels against LED back-lighting as before?
QLED True per-pixel individual light-sourcing (on off etc) vs prior of tuning per pixel color light output over back-light
Operating Efficiency increase of up to 21%
QLED lifetime is now in the million-hour range

That's.... freaking awesome :D

If I can find the educational 'patented' synopsis and research documentation, I will - but there is a university/college somewhere that has found a way to produce a new form/variant of the Plasma Display technology. And it's f'ing amazing.

I just can't remember the name of University, other than it was N.America somewhere...

They dont have to be close to OLED. OLED is terrible for gaming, also i dont like the HDR on OLED peak nits are to low.
If samsung can improve Q-LED then go ahead love the tech :)

what makes oled bad for gaming?
I have only an oled TV and i m using it with a playstation 4.
The experience is new for me and so far looks beautifull for general purpose gaming at 60hz.
What is the terrible part you refer to?

Some OLED's have bad black crush. Burn in on HUD items. They're not as bright as backlit TV's so sometimes struggle in bright rooms.

For movies in darkened rooms OLED's are perfect. But they can struggle in other conditions/uses.
