Just as you thought there was too much TV technology to comprehend, 2022 has yet another. The so-called Quantum Dot OLED (QD-OLED for short) technology, introduced in new TVs from Samsung (its creators) and Sony, combines some of the strengths of OLED and LCD technologies to produce a never-before-seen thing.
QD-OLED marks Samsung’s first foray into all kinds of OLED TV technology in over a decade. LG Electronics.
Also, unexpectedly, Samsung has not positioned QD-OLED as the flagship technology for the 2022 range (that honor goes to the Mini LED TV), and even stranger, it has the same simple marketed under the generic “OLED” technology name. use.
Samsung may not seem particularly enthusiastic about its new technology, but Sony is making its A95K QD OLED TV its flagship 4K model, making people aware of the potential next-generation benefits of its new technology. I was always eager to receive it.
So where’s the truth in this strange mix of seeming enthusiasm and indifference? Are Quantum Dot OLEDs really a quantum leap in TV technology (pun intended) or the OLED emperor’s new clothes? Is it just a case of
Advantages and Disadvantages of Quantum Dot OLEDs
The key to quantum-dot OLED technology is to combine the self-luminous lighting properties of OLEDs with the color gamut and brightness characteristics associated with quantum-dot color systems that were previously limited to relatively high-end LCD TVs.
More specifically, it works by using an organic material to emit blue light at each pixel in the picture, which passes through layers of green and red quantum dots. Brightness can be improved as white OLED light does not need to be passed through RGB color filters like regular OLED TVs do, producing a wider color gamut as there is no pure white to contaminate the procedure will be
The first QD-OLED TVs we’ve seen, Samsung’s QE65S95B and Sony’s XR-55A95K, both convincingly showcased the excellence of the technology. Especially when it comes to colors, both models offer an unprecedented amount and range of colors, revitalizing some of today’s HDR and achieving wide color gamut images unattainable on other types of his OLED TVs. increase.
Local contrast was also quite a revelation, especially with Samsung QD-OLED TVs.Being able to make white pixels even brighter, as QD-OLED allows, makes black pixels white pixels without compromising other pixels. The ability of OLED technology to be placed right next to the OLED looks even more dazzling.
It should be emphasized that even the brighter Samsung QE65S95B of the two new QD-OLEDs can only manage about 10% more brightness than the best regular OLED TVs. It sounds like a pretty small difference on paper, but in practice it makes a much bigger visual impact than you might expect.
In fact, Michael Zink, president and chairman of the UHD Alliance (an industry group of many consumer electronics brands trying to establish performance requirements for today’s displays), publicly expressed his excitement about the arrival of QD-OLEDs. is expressed in This is the first technology to fully meet the high brightness and high contrast requirements of the UHD Alliance’s long-standing “Ultra HD Premium” specification.
QD OLED’s viewing angle support has proven to be near-perfect in both debut models we’ve seen, adding benefits alongside local contrast over LCD TV tech.
An even more surprising advantage of QD-OLED, at least when Samsung’s S95B is concerned, is its price. are also sold at a significantly lower price. Meanwhile, the first OLED and plasma screens to hit the market cost tens of thousands of pounds.
The S95B, on the other hand, isn’t as cheap as most regular OLED TVs, and is certainly at the high end of the TV market compared to most LCD-based models.
One of the technical drawbacks of QD-OLED technology is the potential for screen burn. Prolonged exposure to bright, static image elements can eventually leave shadow-like remnants of these elements on the screen forever. So far, though, there’s been no suggestion that the extra brightness of QD-OLED is more prone to screen burn-in than his OLED. Also, most OLED TVs are much less likely to burn-in than they used to be.
Despite being brighter than regular OLED TVs, Quantum Dot OLED screens can’t deliver the same kind of peak or full-screen brightness as premium LCD TVs. In fact, they’re less than half as bright as the most powerful LCD TVs (most notably Samsung’s flagship QLED model). However, the local contrast feature of QD-OLEDs does not require dimming of the backlight to minimize backlight fogging, so along with the additional luminance consistency it can provide in dark scenes, it is comparable to any current LED screen. It can provide a more consistently illuminated image than .
Pros and Cons of OLED TVs
OLED is essentially taking the baton from home cinema fans’ beloved plasma technology, consuming less power, easier to miniaturize to accommodate higher resolutions, and (eventually ) provides another self-luminous solution that can achieve more brightness and color. Volume than plasma.
Since its ultra-expensive debut, OLED manufacturers have continuously refined the natural benefits afforded by technology in which every pixel in an OLED screen produces its own light, independent of neighboring pixels. Even against the backdrop of ever-increasing brightness levels. Of course, this also means that local contrast is constantly improved, making it more successful than ever to pursue the stringent screen specifications required by today’s high dynamic range image technology.
OLED’s self-luminous nature means it has the widest effective viewing angle of any LED TV, but in some cases the color filtering system can cause slight color shifts when viewed from very wide angles. .
However, the local contrast and viewing angle advantages of OLED are only valid for LCD TVs. They don’t step OLED against QD-OLED, which essentially offers the same benefits as OLED while adding support for a wider color range and more brightness.
In fact, QD-OLED gently highlights the current limitations of ‘RGBW’ OLEDs while at the same time sparking renewed debate about OLED’s historical (albeit diminishing) problem of screen burn-in, so the new QD Are there any areas where you can claim to be more “pro” than your competitors?
There are at least some. First, OLED TVs can be cheap. QD-OLED has arrived at a more affordable price than expected, but while Samsung’s QE65S95B QD OLED actually costs practically the same as LG’s premium OLED65G2 RGBW OLED, most OLED TVs cost significantly more. Low. For example, LG’s OLED65C2 is much more affordable, while the entry-level 55-inch OLED55A2 model is even cheaper.
Of course, QD-OLEDs are likely to be more affordable, and could follow the lead of RGBW OLEDs, offering varying levels of specs to target a wider price range. With the massive production capacity that is currently enjoying and the amount of R&D spending already done to get to where it is today, at least entry-level and mid-range OLED TVs can maintain a sizeable price advantage. must. Still a while.
Another slightly weaker advantage of RGBW OLEDs over QD-OLEDs is the vast number of years of experience behind them now. Panel makers LG Display, LG Electronics (TV brands) and more recently many other TV brands. has worked diligently over the years to improve both the OLED hardware and the core software that drives OLED panels. So QD-OLED definitely got off to a strong start, especially Sony’s QD-OLED, which suggests that the know-how developed for regular OLED screens could translate well to quantum dot OLED screens. It may still take some time, before we see QD-OLED pushed outside of its possibilities.
verdict
Quantum dot OLEDs are really on track. Both of the first QD-OLED TVs we’ve seen have made real strides in terms of brightness, contrast, and especially color gamut. We made it happen at a reasonable price.
However, the traditional form of OLED is now well established enough to support a wide range of specifications, and as a result offers consumers a much more affordable entry point into OLED technology’s self-luminous capabilities. So while QD-OLED certainly poses a tough challenge to the higher reaches of the RGBW OLED world already, enough to suggest that a dazzling future awaits, traditional OLED has plenty of room to continue to thrive for years to come. .
