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 basic differences between micro-OLED and «traditional» OLED.
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 aka OLED on Silicon
The layers of a micro-OLED display.
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 .
Two Sony micro-OLED displays. They look like computer chips because that’s what they’re based on.
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?
The ENGO 2 eyeware uses a tiny micro-OLED made by the company Microoled. The display reflects off the inside of the eyeware to show you your speed, time, direction and other data. 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.
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.

Turns Out Perplexity Might Be the Sleeper Feature on Samsung’s Galaxy S26
Having Perplexity’s AI and models on devices from the world’s biggest phone-maker puts the company under a brighter light.
There were plenty of references to AI at today’s Galaxy Unpacked event. But Samsung isn’t alone; nearly every major smartphone launch in recent years has included new AI features or partnerships with AI companies.
Samsung launched its latest iteration of Galaxy AI, debuting it alongside Galaxy S26 phones. This follows weekend news that the company plans to integrate Perplexity’s AI agent — and even support a «Hey Plex» wake word — on its new phones. But the partnership appears to go beyond simply giving Samsung users another AI option.
Since late 2023, phone-makers have been leapfrogging one another to add generative AI features and integrate AI agents. Nearly every new Android phone supports Google’s Gemini assistant. Apple’s iPhones integrate OpenAI’s ChatGPT into the phone’s Visual Intelligence feature and its Siri overhaul will incorporate Google’s Gemini AI models.
While Perplexity has partnered with phone-makers such as Motorola to preload its app — and has been integrated into devices for Deutsche Telekom — having its AI and models built directly into phones from the world’s largest manufacturer puts the company on a much bigger stage. It marks a shift toward AI agents being just another tool people choose to use, much like a phone app.
«The first step toward an agentic mobile ecosystem is the user getting to choose whatever agent they want,» Dmitry Shevelenko, Perplexity’s chief business officer, told CNET. «I think this is where Samsung is taking a big, big leap forward.»
Perplexity’s Sonar API powers aspects of Samsung’s Galaxy AI ecosystem. Shevelenko said that the company’s engineers worked closely with Samsung’s team to revamp its Bixby assistant at the framework level, getting deep system access. He noted that it’s the first time a third-party AI company has achieved parity on a major mobile OS. The Galaxy S26 phones that Samsung announced support the new «Hey Plex» wake word, putting Perplexity shoulder-to-shoulder with Google’s Gemini AI assistant, which is integrated into Android on Samsung devices.
«What’s unique is the only other company that has it is Google, right?» said Shevelenko. «It’s a real paradigm shift for Samsung to be going into a multi-AI direction, where they are giving their users choice. And I think they see this as a strategic differentiator.»
Samsung’s inclusion of Perplexity touches many of the company’s own apps including Calendar, Clock, Gallery, Notes and Reminders. The benefit of structuring Perplexity’s AI deeply into Samsung’s software is that people can have a lighter interaction with their phones. As opposed to unlocking their device, navigating the home page, opening the app and entering a query, people will be able to simply press a button, say, «Hey Plex,» starting their search within seconds.
But the integration of Perplexity isn’t limited to Bixby. Shevelenko said Samsung’s browser, aptly named Internet, includes agentic browsing using Perplexity’s Comet technology as well.
Such a significant moment for Perplexity naturally draws parallels to Apple and its partnership with OpenAI, which has partnered with former Apple designer Jony Ive for its own hardware efforts. When I asked Shevelenko about the possibility of Perplexity making its own phone or hardware, he responded emphatically, «No.»
«We are laser-focused on working with all the best OEMs,» he said. «Our thing we’re world-class at is building accurate AI that is easy to use and delightful to use and growing that curiosity.»
And while we wait for Samsung to announce new phones, it’ll be interesting to see how Galaxy phone owners use the phone’s AI agents. Soon, people could say, «Hey Google» into their Samsung devices to prompt Gemini, or «Hey Plex» to trigger a query with Perplexity. And options are usually a good thing.
Samsung did not immediately respond to a request for comment.

ADT Acquires AI Company for Sensing People and Activity in Your Home
ADT’s acquisition of Origin AI brings presence-sensing technology under the home security company’s umbrella.
ADT on Tuesday announced an interesting new acquisition for anyone looking to the future of home security — and it’s no surprise AI is a part of the story. In a $170 million deal, ADT has purchased Origin AI, which specializes in people detection in spaces like the inside of your home, something the security company is calling AI-sensing technology.
ADT has not disclosed specific plans for AI technology, but this comes at a time when concerns about corporate surveillance by companies like Ring and Flock have reached a fever pitch.
«ADT has been testing and evaluating Origin’s technology pre-acquisition,» ADT Chief Business Officer Omar Kahn told me. «In 2026, the focus is on integrating the technology into ADT’s platform, with commercialization expected to begin in 2027.»
Presence sensing doesn’t sound like the chatty, summary-creating large language models we consider AI these days, nor the person and car recognition features companies like Flock use. It’s a system that analyzes home Wi-Fi frequencies for disruptions. The AI is trained in pattern recognition to identify which disruptions indicate that humans are at home (ignoring pets) and what they may be doing.
The technology has cropped up in many spots over the past couple of years. I’ve seen it before with aging-in-place technology and Philips Hue’s newest smart bulbs, but most recently with Aqara’s sensor at CES 2026, which can detect when multiple people are congregating, standing, sitting or lying down.
How does presence sensing affect people’s privacy?
It’s not clear how ADT will use Origin’s presence sensing in its home security systems, though the company did mention smart automation, personalization and reducing false alarms. In one example, it could automatically adjust an ADT-supported thermostat when multiple people are detected moving around a house. But that also raises privacy questions.
Presence sensing, like Origin’s tech, has certain privacy benefits. It doesn’t use cameras to film anyone or save video recordings of people, and it doesn’t create identity profiles based on someone’s face or other data. It can’t tell who is in a house, only where they are and how/when they are moving around (or not moving).
That allows for capabilities such as notifying a nursing home that a resident hasn’t gotten out of bed when they usually do, without invasive investigation. But the technology also raises privacy concerns: A company could know when people in their own home are in bed, watching TV, or sitting to eat dinner, even if it can’t identify them by name.
ADT calls features like these home awareness, but also mentions municipal compliance and coordination with first responders. That could mean giving firefighters information on how many people are in a burning building. But there are concerns. Recent news reports indicate that some local law enforcement agencies have shared information with US Immigration and Customs Enforcement for use in home and apartment raids, raising the possibility that the technology could be applied in similar contexts.
The technology’s implications may ultimately hinge on how ADT chooses to implement and regulate it. Until those details are clearer, its promise and its risks remain closely intertwined.

New York Times Debuts the Midi Crossword, Its In-Between Puzzle
Is the Mini Crossword too easy, but the original one just too time-consuming? Here’s your new puzzle.
The daily New York Times Mini Crossword can be solved in a minute or so, while the newspaper’s iconic original crossword puzzle might take hours. Now, puzzlers who want an in-between diversion can try a new puzzle from the Times, introduced this week — the Midi Crossword puzzle. (And CNET readers can get daily answers for five Times puzzles — Wordle, Connections, Strands, Connections: Sports Edition and the Mini Crossword.)
New York Times Games subscribers can play the Midi in the New York Times Games app for iOS and Android devices, or on mobile or desktop web. It’s online-only, not in the print newspaper.
«We’re really leaning into the digital-first nature of the puzzle,» NYT Games Puzzle Editor Ian Livengood said in a Times article about the new puzzle. «About once a week, the puzzle will have a visual effect — an extra flourish when you start or after you solve. This could be a cool animation or colorful shading.»
As the name «Midi» suggests, this is a mid-sized crossword puzzle. Where the Mini Crossword usually only has 5 Across and 5 Down clues, the Midi is usually a 9-by-9 puzzle, sometimes as long as 11-by-11.
«If you feel like the Mini is not enough but the Daily is too much, this will be the perfect puzzle for you,» Livengood said.
Each Midi Crossword has a theme that hints at the topics of the clues and answers. Unlike the other puzzles, Livengood says the Midi might occasionally have two-letter words and repeating answers.
I tried the Midi Crossword
I tried Wednesday’s Midi Crossword and solved it in just over 3 minutes. That’s much longer than I spend on the Mini Crossword, but much faster than the original New York Times crossword puzzle takes me.
I thought most of the clues were pretty simple, and the few tricky ones filled themselves in once I moved from Across to Down.
If you’re a New York Times Games subscriber, this is a nice addition to your daily puzzle stable. It tests your mind a bit more than the Mini, but you can also solve it while watching TV or waiting for someone to text you back.
