What is quantum dot OLED? QD-OLED technology explained



There’s a new buzz in the air: QD-OLED or quantum dot organic light emitting diode, and it’s looking like a game-changer for TVs, monitors, and the like.

Thanks to showings from Samsung and Sony during CES 2022, enthusiasts were treated to the first-ever in-person QD-OLED displays—and it’s looking like a significant jump from standard OLED and QLED technology.

What is QD-OLED?

QD-OLED is a display technology that combines the current popular display tech of OLED with the improved brightness levels of QLED or quantum dot LED.

The end result aims to combine OLED’s perfect blacks and response times, combined with the quantum dot LED’s better brightness and color reproduction. During CES 2022, Samsung captured a Best of Innovation award, while Sony showcased the A95K QD-OLED TV and Alienware showed off an ultrawide QD-OLED gaming monitor.

What’s the difference between QD-OLED, QLED and OLED?

QD-OLED integrates OLED with QLED, combing the best of both worlds from each display technology. But to understand the differences, and why its such an important evolution from modern displays, here’s how the core OLED technology works, why it’s so popular today, and how QLED and QD-OLED play a part.

OLED (or organic LED) is the current display tech to dethrone. You’ve probably heard the term attached to TVs (LG Display has been the undisputed OLED producer for years) or the recent Nintendo Switch OLED.

OLED panels are made from organic materials that produce and discharge light when an electrical current passes through them. This differs to current LCD-LED TVs today, which use always-on light sources like a backlight, to produce an image.

In an OLED TV, the light source is the millions of individual pixels themselves. This is why they can reproduce perfect blacks and better contrast, whereas LCD-LED TVs will often suffer from what’s known as “blooming”—an ugly effect brighter areas of an image will bleed into parts of the screen that are supposed to be entirely black.

OLED has a massive advantage over traditional LED-LCD TVs too. The pixel response time—how long pixels take to transition from one color to another—is near instantaneous on OLED panels. This doesn’t affect the refresh rate of the panel itself, but what it does mean is that moving images are vastly clearer on an OLED panel, which can be a huge boost when trying to identify fast-moving images in games with a lot of characters or action (think PUBG or Fortnite).

Those faster transitions result in better response time during games, too. When using the same PC hardware and Nvidia’s LDAT analysis tools, HDTVTest found that OLED TVs had about 10 milliseconds less end-to-end system lag than traditional LED-LCD screens. That makes OLED vastly more suitable for games like Fortnite, Counter-Strike, PUBG and any twitch-based shooters.

But all these advantages come at a cost. OLEDs are traditionally more expensive, and their lower maximum brightness means they can be poorly suited for rooms with a lot of natural light. Another criticism is image retention or burn-in, although LG display assures that “reasonable, responsible use of an OLED combined with powerful image preservation abilities should result in a seamless experience.”

At its core, quantum dot LED (QLED) is basically an extension of existing LCD-LED technology. Rather than producing images in a completely different way like OLED does, QLED TVs apply a quantum dot layer over the traditional LED backlight to improve brightness, light absorption and color ouptut.

A few drawbacks—especially in comparison to OLEDs—are that QLEDS inherit many of the disadvantages of general LCD technology, including limited contrast ratio, power inefficiency, and slower pixel response times. But the benefit of the quantum dot layer is that it doesn’t just have to be applied to an LED-LCD TV: quantum dot layers can be used with micro-LED, mini-LED and OLED TVs as well.

So how can you retain all of the benefits of OLEDs and QLEDs while improving their shortcomings? The solution: QD-OLED.

Currently, OLED panels create their light and color starting point with white light. They combine blue and yellow OLED material to create a blend of pure white light. From the white light, the red, green, and blue portions are separated from that spectrum—that’s where a color filter comes in. Color filters do a fine job of filtering color, albeit they reduce brightness in the process.

To deal with OLED brightness limitation, QD-OLED panels blast blue light through a quantum dot layer, dividing it into three subpixels to help replicate the full color spectrum.

This has a whole range of benefits. Because blue is the highest frequency light and the most powerful, it’s more power efficient to translate into multiple colors. (And if you’re replicating blue, there’s no conversion needed at all, saving even more power.) Each individual pixel can still be turned off to reproduce OLED’s perfect blacks.

The quantum dot layer also helps with QD-OLED’s color reproduction, especially when it comes to deep reds, golds, or other colors that often suffer from saturation issues on existing OLED TVs. And because the improved efficiency of the technology means less power is required to hit the same level of brightness as previous TVs, it means these newer quantum dot OLEDs should last longer without suffering from burn-in.

When are QD-OLEDs available, how much will they cost?

Enthusiasts can expect the much-anticipated QD-OLED displays in the first half of 2022, according to South Korean insider sources regarding Samsung Display. Also, Sony has become the first company to officially announce a QD-OLED model in its Master Series A95K, so their official release shouldn’t be too far out of reach.

As far as pricing goes, QD-OLED TVs likely won’t be cheap. But with LG Display being the leading producer of OLED displays, Samsung’s emergence as the leading QD-OLED display producer should foster competition, which typically keeps prices lower for the consumer. Any OLED TV will still carry a premium, however, especially in the gaming monitor space where OLEDs have yet to make a mark.

The anticipation is high for QD-OLED displays, and if it can improve upon the combined shortcomings of OLED and QLEDs—as it’s looking like it will, then the future is promising in the display technology space.

Brazilian CS:GO player slams quality of practice in North America



Just days after winning the $20,000 CBCS Invitational 2022 in Brazil over 00 Nation, paiN Gaming have traveled back to North America to play their last matches before the player break. Rodrigo “biguzera” Bittencourt, paiN’s No. 1 star, is not happy at all to practice again with NA teams, though.

“How I missed practicing in NA,” biguzera ironically said today. “[Practicing in] Brazil is a thousand times better than here. Now I see why this region [NA] is so successful,” biguzera added, calling out how the NA players have been practicing.

Biguzera is not the first and likely won’t be the last player to complain about the quality of CS:GO practice in NA. This has historically been a concern in the region and the practice only got worse after the COVID-19 pandemic because several organizations stopped investing in the competition and almost all relevant tournaments shifted to Europe, which forces the only few good teams from NA like Team Liquid to spend most of their time practicing in Europe to have a chance of winning such big tournaments.

This is also the overall perception in Brazil as well. Most of the Brazilian teams move to NA to attend NA leagues and try to qualify for big tournaments, but with the practice being so bad nowadays, it’s unclear if that is the best approach for Brazilian teams. One of biguzera’s fans asked him if paiN could not move to Europe because they will “unlearn” how to play CS in NA.

The quality of practice in NA won’t likely change anytime soon unless organizations try to nurture talent in the region like Evil Geniuses is doing with its Blueprint project and tournament organizers invest in the grassroots scene.

Uncrowned king steps down: Ame takes time off from Dota 2 as LGD begins huge rebuild



Ame, one of the most respected position-one players in the Dota 2 world, revealed that he’ll be taking time off from competitive play today. The news came as a surprise for fans, as PSG.LGD has been one of the most consistent teams in the game’s history.

With even an Aegis in their collection, LGD has been placing top six at The International since 2017. Ame has been a core part of that success since he was recruited from CDEC Youth.

Ame has been a constant in multiple iterations of the LGD roster, which were all one step away from greatness. Ame fell one step short of lifting the Aegis twice in his career, running up in the event in 2021 and 2018 while securing the top four in the remaining ones except for TI11.

Though placing fifth in the most prestigious Dota 2 event of the year is an accomplishment of its own, TI11 marked the worst result for LGD in the event since 2017. Knocking on the door of success this many times only for the door to remain closed can take a toll on players’ mindset toward the game, and it looks like Ame is looking for a complete refresh with this break.

“We’re following the player’s wishes and respecting his personal development needs,” LGD said. “Ame’s status is inactive, temporarily away for rest.”

Ame’s future is currently unknown, but he seems to have the full support of LGD no matter what he decides. Considering Ame has been competing at the top of the Dota 2 mountain for six years now, this is a well-deserved break for the Uncrowned King who fans hope to finally crown when he returns from his break.

With a pillar removed from its roster, LGD only remains with two members in its active squad, NothingToSay and y’, opening the door for a major rebuild.
