What is Micro-OLED? Apple Vision Pro’s Screen Tech Explained

The microscopic version of the beloved display tech winds up the pixels per inch to insane levels. Here’s why Apple and others are so excited about this new version of OLED.

At WWDC 2023, Apple announced the Vision Pro AR/VR headset, which offered an impressive amount of technology and an equally imposing $3,500 price tag. Yet, one of the things that helps the Vision stand out from cheaper products from Valve and Meta is the use of a new type of display called micro-OLED. More than just a rebranding by the marketing experts at Apple, micro-OLED is a variation on the screen technology which has become a staple of best TV lists over the last few years.

Micro-OLED’s main difference from «traditional» OLED is right in the name. Featuring far smaller pixels, micro-OLED has the potential for much, much higher resolutions than traditional OLED: think 4K TV resolutions on chips the size of postage stamps. Until recently, the technology has been used in things like electronic viewfinders in cameras, but the latest versions are larger and even higher resolution, making them perfect for AR and VR headsets.

Here’s an in-depth look at this tech and where it could be used in the future.

What’s OLED?

OLED stands for Organic Light Emitting Diode. The term «organic» means the chemicals that help the OLED create light incorporate the element carbon. The specific chemicals beyond that don’t matter much, at least to us end-users, but suffice it to say when they’re supplied with a bit of energy, they create light. You can read more about how OLED works in What is OLED and what can it do for your TV?.

The benefit of OLED in general is that it creates its own light. So unlike LED LCD TVs, which currently make up the rest of the TV market, each pixel can be turned on and off. When off, they emit no light. You can’t make an LED LCD pixel totally dark unless you turn off the backlight altogether, and this means OLED’s contrast ratio, or the difference between the brightest and darkest part of an image, is basically infinite in comparison.

OLED TVs, almost all manufactured by LG, have been on the market for several years. Meanwhile, Samsung Display has recently introduced OLED TVs that also feature quantum dots (QD-OLED), which offer even higher brightness and potentially greater color. These QD-OLEDs are sold by Samsung, Sony, and, in computer monitor form, Alienware.

Micro-OLED, also known as OLEDoS and OLED microdisplays, is one of the rare cases where the tech is exactly as it sounds: tiny OLED «micro» displays. In this case, not only are the pixels themselves smaller, but the entire «panels» are smaller. This is possible thanks to advancements in manufacturing, including mounting the display-making segments in each pixel directly to a silicone chip. This enables pixels to be much, much smaller .

If we take a look at Apple’s claims, we can estimate how small these pixels really are. Firstly, Apple says the twin displays in the Vision Pro include «More pixels than a 4K TV. For each eye» or «23 million pixels.» A 4K TV is 3,840×2,160, or 8,294,400 pixels, so that should equate to around 11,500,000 pixels per eye for the Apple screens.

Next, Apple partnered with Sony (or maybe TSMC) to create these micro-OLED displays and they are approximately 1-inch in size. To calculate the size of each pixel I’m going to use 32-inch 4K TVs as a comparison, and these boast about 138 pixels per inch (ppi). We don’t know the aspect ratio of the chips in the Vision Pro, but if they’re a square 3,400×3,400 resolution that would be a total of 11,560,000 pixels, so that’s a safe bet. So, if that’s the case, these displays have a ppi of around 4,808(!) and that’s more than almost anything else on the market, and that’s by a lot. Even the high-resolution OLED screen on the Galaxy S23 Ultra has a ppi of «only» 500. Regardless of the panel’s production aspect ratio, the ppi is going to be impressive. Apple didn’t respond immediately to CNET’s request for clarification.

AR and VR microdisplays are so close to your eyes that they need to be extremely high performance in order to be realistic. They need extreme resolution so you don’t see the pixels, they need high contrast ratios so they look realistic, and they need high framerates to minimize the chance of motion blur and motion sickness. In addition, being in portable devices means they need to be able to do all that with low power consumption. Micro-OLED seems able to do all of these, but at a cost. Literally a cost. The Vision Pro is the most high-profile use of the high-end of the technology and it costs $3,500.

The Micro-OLED technology isn’t particularly new, having been available in some form for over a decade. Sony has been using them in camera viewfinders for several years, as have Canon and Nikon. Like all display techs, however, micro-OLED has evolved quite a bit over the years. The displays in the Vision Pro, for instance, are huge and very high resolution for a micro-OLED display.

How is micro-OLED different from MicroLED? Despite the fact that they’re written slightly differently, they are superficially similar in the way they are both self-emitting, or can make their own light. But on a more in-depth level, the differences between the carbon-based OLED and the non-carbon LED are sadly beyond the scope of this article. Suffice it to say right now, MicroLED is better suited for large, wall-sized displays using individual pixels made up of LEDs. Micro-OLED is better suited for tiny, high-resolution displays. This isn’t to say that MicroLED can’t be used in smaller displays, and we’ll likely see some eventually. But for now they’re different tools for different uses.

The future is micro?

Basically anything an athlete would need for better training, but instead of on a watch or phone, it’s projected in real time in front of you. Essentially, a heads-up display built into sunglasses.

ENGO

Where else will we see micro-OLED? At MWC 2023, Xiaomi announced its AR Glass Discovery Edition featured the technology, and future high-end VR headsets from Meta, HTC and others will likely use it. Currently, a company named Engo is using a tiny micro-OLED projector to display speed and other data on the inside of its AR sunglasses. I know I sure don’t need these, but I want them. Then there’s the many mirrorless and other cameras that have been using micro-OLED viewfinders for years.

Could we see ultra-ultra-ultra high-resolution TVs with this new technology? Technically, it’s possible but highly unlikely. Macro micro-OLED is just OLED. The resolutions possible using more traditional OLED manufacturing are more than enough for a display that’s 10 feet from your eyeballs. However, it’s possible micro-OLED might find its way into wearables and other portable devices where its size, resolution and efficiency will be an asset. That’s likely why LG, Samsung Display, Sony and others are all working on micro-OLED.

Will ultra-thin, ultra-high resolution micro-OLED displays compete in a market with ultra-thin, ultra-high resolution nanoLED? Could be. We shall see.

McDonald’s KPop Demon Hunter Meals Include Bright Purple Nugget Sauce

The Derpy McFlurry mixes popping boba pearls and berry sauce into a soft-serve dessert.

McDonald’s has seen success with themed combo meals, including its holiday Grinch Meal. Now, the fast-food chain is capitalizing on Netflix’s Oscar-winning animated film, KPop Demon Hunters, with new upcoming menu items and both a breakfast meal and a lunch/dinner offering. Let’s hope you like the color purple.

The HUNTR/X Meal, named for the K-pop girl group in the movie, is a 10-piece chicken McNuggets meal that includes a medium drink and three special menu items.

Ramyeon McShaker fries come with a small bag of soy, garlic, sesame and spice seasoning, along with regular McDonald’s french fries. You sprinkle the seasoning into the provided bag, dump in the fries, shake it all up and eat.

The meal includes two new sauces for the fries and nuggets. Hunter sauce is a sweet chili sauce mixing notes of chili, garlic and pepper. But my favorite item on this new menu is Demon sauce, a bold mustard sauce with some heat and a bold purple color. There’s just not enough dark purple food out there.

There’s also a new dessert, the Derpy McFlurry, which blends creamy vanilla soft serve with berry-flavored popping boba pearls, served with a swirl of wild berry sauce. McDonald’s named it for the supernatural feline, Derpy Tiger, from the movie.

If breakfast is your bag, the new morning meal is the Saja Boys Breakfast Meal, named for the movie’s boy band.

It includes a Spicy Saja McMuffin sandwich, which is a sausage McMuffin with egg and a spicy Saja sauce, hash browns and a small drink.

Both meals come with a photocard for one of the bands and a Derpy card. The Derpy card includes a QR code you can scan to unlock online content about the film.

The full KPop Demon Hunters menu should be available at participating McDonald’s beginning March 31.

The McDonald’s Grinch meal (and its accompanying patterned socks) sold out quickly, so KPop Demon Hunters fans may want to mark their calendars and nab a meal when they are released.

Melania Trump Escorted by Talking Humanoid Robot at White House Tech Summit

The first lady shared the spotlight with the robot to promote the use of artificial intelligence in education.

An unexpected guest escorted Melania Trump at the Fostering the Future Together Global Coalition Summit on Wednesday: a Figure 03 humanoid robot.

During the event, the first lady pitched a future where AI-powered humanoid robots — presented as an idealized educator named «Plato» — provide students with personalized and instant access to human knowledge, including philosophy and art.

The Figure 03 robot is made by Silicon Valley-based robotics company Figure AI, which introduced its third-generation humanoid robot in October last year. The Figure 03 robot costs around $25,000, according to Forbes.

Figure 03 was designed for people to use in their homes, with demo videos showing it folding laundry, lifting eggs from a carton, using a washing machine and delivering drinks to its owners lounging by the pool. It was also shown in corporate use cases as a receptionist and a package deliverer. Using a proprietary AI engine called Helix, it can autonomously perform these tasks and respond to your voice commands.

The humanoid was seen walking slowly down the red carpet at the tech summit and then delivering opening remarks.

«I’m grateful to be part of this historic movement to empower children with technology and education,» the Figure 03 humanoid robot said. It then said «welcome» in various languages.

The first lady later said that AI-powered humanoid robots could exist in children’s homes as an aid to their education to «boost analytic skills and problem solving and adopt in real time to a student’s pace, prior knowledge and even emotional state.»

The two-day summit is hosting leaders from 45 nations and 28 technology organizations, and is intended to «empower children through education and technology,» according to a White House statement. Guests included representatives from tech giants such as Google, OpenAI, Microsoft and AI data analytics company Palantir.

The summit is part of the first lady’s Be Best: Fostering the Future initiative, which aims to help children learn using advanced technology. It was introduced in 2018 as an awareness campaign aimed at combating cyberbullying and helping children affected by the opioid crisis.

US Education Secretary Linda McMahon spoke about AI being one of the Department of Education’s main priorities on the first day of the summit.

«If we’re able to scale these resources effectively by investing in AI infrastructure and training, we can offer expert instructions across countless fields, to hire volumes of people at a fraction of the cost,» McMahon said Tuesday at a round table meeting.

According to McMahon, the Department of Education has already dedicated millions of dollars in grants to support the use of AI in schools.

The event follows criticism of the Trump administration’s 2025 executive order to dismantle the Department of Education. While the Department of Education hasn’t been officially abolished, it has undergone significant policy changes, funding cuts and workforce reductions.

The introduction of a humanoid robot at the summit sparked significant backlash among many who are wary of the technology’s role in the classroom. Critics took to social media to voice concerns that these machines could eventually replace teachers, stripping the education system of essential human connection, and leading to increased layoffs and cost-cutting.

On one Huffington Post Instagram post featuring the robot, commenters expressed deep skepticism, with one user sarcastically noting, «Nice, getting rid of educators in favor of a robot,» while another flatly rejected the concept, stating, «No, I don’t want to imagine a world with emotionless robots educating our children.»

The White House did not immediately respond to a request for comment.

Nintendo Dropped a Switch 2 Update With a New Mode You’ll Want to Turn On Immediately

This new feature is one of the best yet.

A new firmware update hit the Nintendo Switch 2 last week. Among the multitude of small changes is a new feature that will give Switch 1 games a notable upgrade.

Version 22.0.0 for the Switch 2 went live on March 16 and is available for download to the console. The big new feature in the update was Handheld Mode Boost, which will give Switch 1 games a visual upgrade when played on the Switch 2 in handheld mode.

— OatmealDome (@OatmealDome) March 17, 2026

What does Handheld Mode Boost do?

Even though the Switch 2 supports backward compatibility with almost all Switch 1 games, there was an issue. The Switch 2 has a higher resolution screen: 1080p versus the older hardware’s 720p. When playing a Switch 1 game on a Switch 2 in handheld mode, the graphics looked blurry and jagged.

When enabled, Handheld Mode Boost makes a Switch 1 game act as if it’s docked, so it displays 1080p at 60 frames per second. This will give the visuals an immediate upgrade.

How do you enable Handheld Mode Boost?

Handheld Mode Boost has to be turned on to see the effect, and it takes a few steps:

Select Systems Settings from the Home menu
Select System
Select Nintendo Switch Software Handling
Enable Handheld Mode Boost

Is there a downside to enabling Handheld Mode Boost?

A user on Reddit tested the mode to see how it affects the Switch 2’s battery life. The test used Doom Eternal for the Switch 1 with and without Handheld Mode Boost. The test showed that the battery life decreased from 5 hours, 5 minutes to 3 hours, 43 minutes. That’s a 27% drop and should be taken into account when using Handheld Mode Boost.

How do I upgrade my Nintendo Switch 2?

If you have Software Auto-Updates enabled on your Switch 2, a pop-up window should come up whenever you start a game. If not, head to System Settings and choose to update the console from the menu.

What other features were added in version 22.0.0?

Handheld Mode Boost was the main star of the new firmware update, but there were a slew of other changes.

Changed the on-screen text and animations when you load a virtual game card in the HOME Menu.

Added the ability to save notes about friends on your Friend List. The note content is not displayed to friends.

Added the ability to invite friends to GameChat rooms you’re participating in. Some friends may not be able to be invited, such as supervised accounts.

Friends who haven’t finished GameChat’s initial setup can now be invited to GameChat. Some friends may not be able to be invited, such as supervised accounts or those who haven’t used a Nintendo Switch 2.

Added the ability to rewind 10 seconds/advance 10 seconds with the ZL and ZR Buttons when watching a full-screen video in News or Nintendo eShop.

Added the option to add the following data to «Automatic Uploads» from Album.

Text-to-Speech, under Accessibility, can now read the text in Album and during first-time setup.

Added the ability to see the breakdown of storage capacity by data type for the system memory and microSD Express card.

Added the ability to perform an audio test when «Linear PCM 5.1 Surround» is selected for TV Sound in Audio.

When Airplane Mode is activated, the previously set preferences for Bluetooth, Wi-Fi or NFC while in airplane mode will be saved and applied.

Added the ability to individually enable or disable Bluetooth, Wi-Fi or NFC during Airplane Mode from the Quick Settings.

Added the ability to see a notification in the Nintendo Switch Parental Controls smart device application when the Parental Controls PIN is input successfully on the console. This can also be set up to be a push notification to your smart device.

General system stability improvements to enhance the user’s experience.
