Samsung’s QD-OLED TV might be here very soon. Here’s everything we know

Samsung’s rumored OLED TV with quantum dots could be coming as soon as 2022, and the new technology is set to challenge the best from rival LG.

Most people have two options when it comes to TV technology: LCD and OLED. Sure, some people also have the choice of a MicroLED TV, but those can be pricey. Samsung, the biggest TV-maker in the world, has been planted in the LCD camp for many years, while its rival LG is the biggest name in OLED. Despite advancements like QLED, mini-LED and dual panels, LCD has always lagged behind OLED in overall picture quality.

Now Samsung is working on a new kind of TV that aims to combine two display technologies into something greater. It’s a hybrid between OLED and quantum dots called QD Display. Samsung Display will end production of LCD panels by the end of 2021, moving to QD Display next year, according to a February report from Korea IT News. At the same time, Samsung Electronics could start selling these new TVs as early as 2022.

Samsung’s $11 billion bet on quantum dots

Samsung has been selling LCD TVs enhanced by quantum dots for the last few years under its QLED brand, but its last (and only) OLED TV was a one-off that it stopped selling almost a decade ago. In October 2019, Samsung Display announced it was building a factory to make TVs that combined these technologies:

Samsung Display will invest 13.1 trillion won by 2025 to build «Q1 Line,» the world’s first QD display mass production line at Asan Campus. The new line is scheduled to start production in 2021 with an initial 30,000 sheets (8.5 generations) and will produce a huge QD display of 65 inches or larger.

That’s an investment of around $11.1 billion. While the company calls this «QD display,» it isn’t electroluminescent, aka «direct view» quantum dots. That technology is still several years away. This is going to be a QD-OLED hybrid.

At the announcement, South Korean President Moon Jae-in also referenced Samsung’s rival LG in regards to Korea’s place in world TV production: «It is important to maintain the top spot of the global display market with game-changing technologies,» Moon said. «Following LG Display’s 3 trillion-won investment in large OLED panel production in July, Samsung Display’s latest investment plan brightens prospects further.»

One thing you might have noticed is that Samsung is calling this «QD display,» which can be confusing since this isn’t direct-view quantum dots (more on these later). Since LG has spent years being the only name in town (figuratively and literally) for OLED, it’s unlikely Samsung will call any version of this technology OLED. We’ll probably have to wait until CES 2022 to find out how it brands the new TV.

What is QD-OLED and how will it work?

So how will it work? Nanosys, a company that makes quantum dots, has shared some details. Its CEO, Jason Hartlove, is understandably bullish on the technology, which relies on converting light from an OLED panel:

«Quantum Dot Color Conversion is a completely new way of rendering color in displays,» he told CNET. «The result is pure quantum dot color with much higher efficiency as no light is lost in a color filter.»

Combining quantum dots and OLED plays to the strengths of both technologies. The idea with any TV is to create red, green and blue light. LED LCDs with quantum dots, like Samsung’s current QLED TVs, use blue LEDs and a layer of quantum dots to convert some of that blue into red and green. With the current version of OLED, yellow and blue OLED materials create «white» light. In both cases, color filters let pass only what color is needed for that specific subpixel.

The idea with a QD-OLED is to simplify these designs into one, by using OLED to create blue light, and then a quantum dot layer to convert some of the blue into red and green.

There are many advantages to this method, in theory. By using only one color or material of OLED, the manufacturing costs go way down since it’s easier to build. LG, for instance, uses only two OLED materials, blue and yellow, for every pixel across the entire display. Light-blockingcolor filters create the green and red. QDs have nearly 100% efficiency, significantly better than filters, so in theory the hybrid TVs will be much brighter. Plus, there’s the possibility of even wider color gamuts at all brightness levels.

Because each pixel can be shut off, these hybrid TVs will also have the incredible contrast ratios that OLED is known for.

Since blue OLED materials still age faster than red and green, having the entire panel one color means the TV ages more evenly with no color shift. Keeping that aging to a minimum, and thereby having a TV that doesn’t seem dim after a few years, is one of the key manufacturing issues. This is especially true in this HDR era of extreme brightness levels.

While this new Samsung plant is focusing on TV-size displays, the technology could work in phone-sized displays as well. Since Samsung doesn’t seem to have any issue making excellent small OLEDs, I’d be surprised if it’s in any rush to upset that market with something as advanced as this. Also, Samsung’s phone-sized OLEDs use red, green and blue OLEDs compared to LG’s blue-yellow. Samsung tried to make RGB OLED TVs and just couldn’t make them profitable. What’s more likely, and mentioned in the latest rumors, is they’ll use this tech to build ultra-high resolution 8K computer monitors along with larger TV screens.

As mentioned earlier, it’s clear Samsung believes strongly in this technology, since it’s ending production of LCDs at its factories in Korea. This doesn’t mean that starting next year it won’t sell any LCDs. Samsung is a massive company, and the part of the company that makes LCDs, Samsung Display, is stopping production. The part of the company that sells TVs, Samsung Electronics, has made no such announcement. In fact, part of the most recent delay was Samsung Electronics needing LCD panels before they were ready to start selling QD-OLED panels. They’ve worked that out for 2021, and most likely going forward they’ll source their LCD panels from a third party.

Into the future: Direct-view quantum dots, ELQD and more

QD-OLED seems to be right around the corner. But what about even farther-future display tech? Well, the quantum dot folks seem to think direct-view quantum dot displays are just a few years off. These electroluminescent quantum dots, or ELQD, would have all the benefits of OLED, all the benefits of QD and none of the issues of LCD or the wear and longevity concerns of OLED. A very promising tech indeed.

The other new TV tech that’s already arriving on the market, the extreme high-end of the market anyway, is MicroLED. It has many of the same benefits as the QD-OLED hybrid, but doesn’t muck around with those pesky organics. Affordable versions of that are still some distance off. Oh, and MicroLEDs use quantum dots too. They’re a fascinating technology with uses far beyond TV screens.

In the meantime, we’ve got mini-LED, which is pretty cool too and far less expensive than any of these.

Samsung Galaxy Z Fold 7 Display Can Be Folded 500,000 Times, According to Testing

The display can be folded more than double the number of times as the previous iteration before it will break.

Fold, fold and fold again. It doesn’t matter how many times you open and close the Galaxy Z Fold 7 phone — it’s highly unlikely to give out on you. Samsung Display (SDC) announced Tuesday that its latest foldable OLED panel «remained fully functional after a 500,000-fold durability test,» more than doubling its previous benchmark of 200,000 folds.

Bureau Veritas, a French leader in testing, inspection and certification, tested the screen with 500,000 folds over a 13-day period at a temperature of 25°C (77°F).

For those of you trying to wrap your head around the math, half a million folds translates to the average user folding their phone 100 times a day for 10 years, or prolific users doing 200 folds a day for 6 years. Samsung Display — a separate company from Samsung — says the durability results prove that «durability is no longer a limiting factor in the lifespan of foldable smartphones.»

«As foldable OLED enters its seventh year of commercialization, we’ve achieved another meaningful breakthrough in both durability and design,» Hojung Lee, EVP at Samsung Display, said in a press release. «This new panel … builds consumer confidence in foldable OLED durability.»

Bulletproof glass technology has helped Samsung Display develop its creaseless screens. SDC borrowed from the concept and increased the thickness of its Ultra Thin Glass, the outermost glass on the screen, by 50%. SDC also added high-elastic adhesive to each screen layer, thereby enhancing fold recovery performance by four times the previous design.

CNET reported last week that Apple has tapped Samsung Display to manufacture screens for Apple’s first foldable iPhone, set to launch in summer 2026.

Despite the hype around foldable phones, a CNET survey published on Tuesday showed 64% of people have no interest in buying one of these smartphones in the next year. 20% weren’t sure if they want one, 13% say they do want one and just 3% said they already own one.

Microsoft Will Wipe Out Your Passwords on Aug. 1. What to Do Now

The clock’s ticking to find a new password manager other than Microsoft Authenticator.

Microsoft is getting rid of passwords in less than two weeks.

On Aug. 1, the Microsoft Authenticator app will no longer store or manage passwords, which could be a problem for a lot of users. Microsoft Authenticator has been one of the best password managers for years. You were able to save passwords, enable two-factor authentication and auto-fill. This change means that if you’re using the Authenticator app as a password manager, you’ll need to look for another option soon.

At the same time, Microsoft will move to passkeys instead.

Using a passkey as a login means you’ll use PINs, fingerprint scans, facial recognition or a pattern on a device’s lock screen. It’s a safer option compared to the risky password habits. A CNET survey found that 49% of US adults have bad password habits. Having an insecure password can put you at risk of having your information exposed.

If you’ve been using Microsoft Authenticator, now’s the time to start making changes. Here’s what to know about the switch and the best password managers CNET recommends.

When will Microsoft Authenticator stop supporting passwords?

Microsoft Authenticator houses your passwords and lets you sign into all your Microsoft accounts using a PIN, facial recognition like Windows Hello, or other biometric data like a fingerprint. Authenticator can be used in other ways, such as verifying you’re logging in if you forgot your password, or using two-factor authentication as an extra layer of security for your accounts. In June, the company stopped letting users add passwords to Authenticator.

Starting this month, you won’t be able to use the autofill password function. And next month, you’ll no longer be able to use saved passwords.

If you still want to use passwords instead of passkeys, you can store them in Microsoft Edge. However, CNET experts recommend adopting passkeys during this transition. «Passkeys use public key cryptography to authenticate users, rather than relying on users themselves creating their own (often weak or reused) passwords to access their online accounts,» Tomaschek said.

Why are passkeys a better alternative to passwords?

So what exactly is a passkey? It’s a credential created by the Fast Identity Online Alliance that uses biometric data or a PIN to verify your identity and access your account. Think about using your fingerprint or Face ID to log into your account. That’s generally safer than using a password that is easy to guess or susceptible to a phishing attack.

«Passwords can be cracked, whereas passkeys need both the public and the locally stored private key to authenticate users, which can help mitigate risks like falling victim to phishing and brute-force or credential-stuffing attacks,» said Attila Tomaschek, CNET’s software senior writer and digital security expert.

Passkeys aren’t stored on servers like passwords. Instead, they’re stored only on your personal device. More conveniently, this takes the guesswork out of remembering your passwords and the need for a password manager.

How to set up a passkey in Microsoft Authenticator

Microsoft said in a May 1 blog post that it will automatically detect the best passkey to set up and make that your default sign-in option. «If you have a password and ‘one-time code’ set up on your account, we’ll prompt you to sign in with your one-time code instead of your password. After you’re signed in, you’ll be prompted to enroll a passkey. Then the next time you sign in, you’ll be prompted to sign in with your passkey,» according to the blog post.

To set up a new passkey, open your Authenticator app on your phone. Tap on your account and select «Set up a passkey.» You’ll be prompted to log in with your existing credentials. After you’re logged in, you can set up the passkey.

Other password manager alternatives

Since Microsoft will get rid of all of your passwords in two weeks, you’ll need a new place to store your passwords safely. Tomaschek has a few of the best password manager recommendations after testing and reviewing several.

The top recommendation is Bitwarden for its transparency. It’s open-source and audited annually. From a price perspective, the free plan lets you store infinite passwords across unlimited devices. The free plan also includes features most password managers would charge for, including password sharing and a username and password generator.

Bitwarden’s upgraded plans have other upgraded features that could be worth the cost, too.

Personally, Tomaschek has been using 1Password for a while, and he likes the interface and family plan. Even though it’s second on the list, Tomaschek says it’s just as good as Bitwarden.
