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.

Here’s what we’ve heard about Samsung’s new display technology so far.

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.

Step Out of the Shadows. How to Turn Off Your iPhone’s Incognito Mode

The iPhone’s incognito mode is ideal for sensitive searches and avoiding targeted ads. But there are time when you may want to turn it off.

At a time when privacy and security have become hot topics, it’s smart to look at how you’re using protections built-in your phone. The iPhone’s private browsing, also known as incognito mode, serves as a digital cloak — allowing you to surf the web without leaving traces. Private browsing works on Apple’s Safari browser and some third-party browsers like Chrome.

There are a whole range of reasons to take advantage of incognito mode. You might be using a shared device, researching sensitive topics (maybe a surprise gift idea?) or dialing your privacy precautions up a notch by working to circumvent targeted ads or third-party cookies. This is when incognito mode becomes something of a confidante, and it gives you an added layer of privacy protection.

But once you’ve finished, you might want to step out of incognito mode on your iPhone and allow your browser to remember your steps. For example, maybe you’re logged into your account on a retailer’s website and don’t want to have to log back in every time you visit the page. Let’s proceed with a step-by-step guide on how to exit incognito mode on an iPhone, using Safari and Chrome.

How to exit incognito mode on Safari

1. Open Safari: Launch the Safari browser on your iPhone. You’ll find its icon on the home screen.

2. Look for the Tabs button: At the bottom right corner of the screen, you’ll see a square icon overlapping another square. Tap on it. This button represents your open tabs.

3. View all tabs: Once you tap the Tabs button, you’ll see a screen displaying all your open tabs. These tabs might include regular browsing tabs, any Tab Groups you’ve made and any incognito tabs you’ve opened called Private Browsing.

4. Close incognito tabs: Swipe left on any private or incognito tabs you want to close. After closing all incognito tabs, you’re officially out of incognito mode! You’ll now be browsing in regular mode, and your browsing history will be saved. If you have too many tabs open and prefer not to close every single one, you can simply swipe left in the view all tabs screen from Private/incognito tabs to get back on regular mode.

How to exit Incognito mode on Chrome on your iPhone

If you use Google’s Chrome browser, you’ll follow a familiar process to leave incognito mode.

1. Open Google Chrome: Launch the Chrome browser on your iPhone.

2. Look for the Tabs Button: At the bottom right corner of the screen, you’ll see a square icon with a number on it (if you have open tabs). Tap on it. This button represents your open tabs and the number corresponds with how many tabs you have open.

3. Leave Incognito mode: After tapping on the tabs button, you’ll be able to switch between incognito browsing or regular browsing by tapping the Incognito icon or the regular browsing icon. The Incognito icon is a pair of glasses and a fedora to resemble a secret disguise. To go back to browsing on regular mode, simply tap the square button with the number on it.

How to permanently turn off private browsing on an iPhone

You can also remove the private browsing tab on Safari. In Settings under Screen Time, when you switch Web Content from «Unrestricted» to «Limit Adult Websites,» the iPhone reboots Safari and removes Private Browsing from the Tabs view. To get to the setting you open Settings, tap Screen Time, tap Content & Privacy Restrictions, tap Store, Web, Siri & Game Center Content, select Web Content and tap Limit Adult Websites.

Remember, using incognito mode isn’t foolproof — it won’t hide your activity from your internet service provider or certain extensions. But it’s supposed to offer that extra layer of privacy when needed.
