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.

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.

If You’re Not Using ChatGPT for These 9 Things, You’re Working Way Too Hard

There are tons of things that ChatGPT just can’t handle. But you can feel good about trying these prompts out.

Like it or not, AI is everywhere. If ChatGPT isn’t the topic of conversation around you at work or at home, you’re hearing about it in the news and through other companies. Though it’s ubiquitous, however, it’s important to remember that it isn’t an all-knowing digital deity. It is, in fact, prone to offering misinformation and making mistakes. But that doesn’t mean that you shouldn’t skip using it at all. 

You should play around with AI to see its possibilities and limits. Be curious, experimental and have fun with it. There are some things you definitely shouldn’t use ChatGPT for, such as health diagnoses and legal decisions, but there are plenty of tasks and to-dos it’s great for.

ChatGPT isn’t alone out there. You can also use other chatbots for these tasks, like Google’s Gemini, Anthropic’s Claude and Perplexity. And because AI has the propensity to hallucinate answers, draw the wrong conclusions or make things up entirely, be sure to always double-check and use common sense whenever it gives you information.

Here’s a look at nine of the best things to use AI chatbots for. 

(Disclosure: Ziff Davis, CNET’s parent company, in April filed a lawsuit against OpenAI, alleging it infringed Ziff Davis copyrights in training and operating its AI systems.)

1. A beefed-up search engine 

I heard somewhere that millennials use ChatGPT as a search engine, while Gen Z uses it more as a «life advisor.» I’m showing my age here, but I love using it as a search engine on steroids. 

It’s really handy to be able to learn about a specific topic from one information interface. I use it for both quick answers to questions and in-depth topical research. 

ChatGPT’s Agent Mode can also run specific searches for you while you’re doing something else. 

2. Beauty and style advice 

This one’s fun. If you’re stuck on what lipstick suits your skin tone, what haircut is best for your face shape or how to accessorize an outfit, ask ChatGPT. 

You can upload a selfie and ask it for beauty advice or even how you’ll age (and what you can do about it). Ask who your doppelganger is.

3. Menu planning 

You can tell ChatGPT what’s in your fridge and pantry, and it’ll make a menu. This is a good little hack in this economy, especially with the holiday season coming up, and when your fridge is full of leftovers. 

You can also do other fun things, like take a photo of a menu at a restaurant and ask for the best wine pairing, if your server doesn’t beat you to it. 

4. Redesigning a room 

Whenever I try to create a cool art design in AI, it always falls short. But uploading a photo and asking it to redesign a room? Nails it. 

I prompted ChatGPT with the problems I was having with the space and what I envisioned for it, then it «redesigned» it within seconds. 

Try it with a room, an area or a nook that you want to jazz up in your home. It might not be perfect, but it will give you ideas on placement, paint colors, furniture and vibe. 

5. In your job search 

We all know how horrid the job market is right now, so you should absolutely leverage AI if you’re on the hunt. 

You can use it as a career coach, to find current openings, feed it job links and ask it to tell you why you’re a good candidate, create cover letters and refine your resume. Always edit your cover letter and resume and pepper it with your personality. Avoid sounding like everyone else using AI. 

6. To research people 

If you’re preparing for a job interview, talking to a potential client, meeting someone at a networking event, going on a date or wanting to look up an actor while watching TV, ChatGPT is a great way to find them. If I have a call coming up, I usually ask ChatGPT to «tell me everything I need to know about this person and their background.»

It can also help to find contact details, but always fact-check and be respectful. For example, I asked ChatGPT who someone was, and it gave me a name and email within seconds.

7. Tech troubles 

We’re all surrounded by so much tech, but not all of us have a handy spouse or tech support on call. I’ve turned to ChatGPT for issues like missing meeting recordings, storage issues on my MacBook, setting up YouTube on my TV, and whether my constantly humming fridge needs to be fixed. 

I wouldn’t try my hand at plumbing or anything electrical-related, but it’s helpful to troubleshoot tech.

8. Travel research 

I’m one of those people who thinks travel planning is part of the trip. I love researching destinations, looking at accommodations, comparing flights and planning things to do. 

ChatGPT can come in handy, especially in destination research. I haven’t had much luck using it to find cheap flights, but it’s awesome to ask about certain neighborhoods to stay in, the best times to visit, planning itineraries and getting travel tips. 

9. (Some) personal advice 

ChatGPT is an awesome thought partner, but just be wary about its people-pleasing tendencies. It’ll agree with you, unless you prompt it not to. Also, chatbots have nothing on your BFF or partner, who actually know what’s good for you. 

But if you can keep this in mind, it’s a handy «life advisor.» You can talk through a problem you’re having, role-play with it, ask it for advice, plan a career move, ask it to unpack the tone of a message and use it as a guide while going through something. In my case, I leaned on it while I was going through my first round of IVF.

A word of warning: ChatGPT uses a predictive model, so its «advice» is based on what you’ve told it before. It’s not going to «think» outside the box, so confirmation bias is a concern.

These Phones Have Gamer-Chic Looks, Touch Triggers and Cost Less Than the iPhone 17E

ZTE’s Nubia Neo 5 series of gaming phones has everything a die-hard mobile gamer could want: A big battery, fans and capacitive buttons for gaming.

ZTE has a trio of new phones that will make gamers happy, which it revealed at MWC 2026. The Nubia Neo 5 series takes some of the coolest features from the premium RedMagic 11 Pro (launched back in November) and packs them into budget phones — though they won’t be coming to the US any time soon.

Gaming phones are aimed at people who want the best performance, graphics and battery life from their handheld. These phones, aimed at mobile gamers, have always been niche devices, but many, like the RedMagic series and ASUS’ ROG devices, have been pricey, high-end handsets with elite features. ZTE’s Neo 5 phones are an attempt to introduce some of those cool perks at low enough costs to undercut or rival devices like the iPhone 17E or Google Pixel 10A. And as the RAM shortage could cause phone prices to rise this year (as we’ve already seen with the Galaxy S26 phones), consumers might look for cheaper options like the Neo 5 series.

The cream of ZTE’s budget crop is the Neo 5 GT. Priced at 450 euros (roughly $430), it inherits most of the RedMagic 11 Pro’s features. The most prominent is an internal cooling fan that, combined with the Neo 5 series’ heat-absorbing layer, cools the phone’s internals by 4 degrees Celsius, ZTE estimates. Fan ports are visible on either side of the phone near the volume and lock buttons, so it’s safe to say the phone should be kept away from dust and water (ZTE hasn’t released IP ratings for the Neo 5 GT).

The GT has a «gamer chic» look with LED lights. It has a 6,120-mAh battery and 80-watt charging and a 6.8-inch AMOLED display with a 144Hz refresh rate; features more common in handsets twice the price. The phone also packs capacitive touch shoulder buttons with latency below 5.5 milliseconds. 

The Nubia Neo 5 is the baseline model, which will retail for about 300 euros (roughly $350), with capacitive shoulder buttons and a cooling layer that ZTE estimates reduces internal temperatures by 2 degrees Celsius. 

The step-up Neo 5 Max lives up to its name. For about 350 euros (roughly $415), it has a 7.5-inch display — nearly as big as the 8-inch inner screen on the Samsung Galaxy Z Fold 7 — and a battery with over 7,000 mAh.

With features that make them competitive with pricier phones, such as the Google Pixel 10A, the Neo 5 phones will appeal to anyone, especially mobile gamers. The Neo 5 and Neo 5 GT are expected to start selling in Europe in April, then later in parts of Latin America. The Neo 5 Max will reach the same regions around July, ZTE said. It’s unclear if or when they’ll be sold in the US.

Tecno’s New Concept Phones Get Even Slimmer at MWC 2026

The company showed off its latest ultrathin handsets, including a new trifold.

Wherever crowds converge at Mobile World Congress, there’s likely to be a thin or foldable phone — or both — on display. That was certainly the case at Tecno’s booth, where the phone-maker showed off several concept devices with astoundingly slim designs. 

The Tecno Slim 2 is a follow-up to last year’s Spark Slim, which I first saw as a concept at MWC 2025 before its eventual release. The upgraded model pares down the Spark Slim’s 5.93mm frame even more, to 5.49mm. It’s frankly a barely noticeable difference, given the minuscule unit of measurement. But it’s a testament to how phone companies keep pushing the boundaries of mobile hardware to develop jaw-droppingly thin and light phones. The Slim 2 also has super-narrow 0.7mm bezels for more immersive viewing.   

Another concept repurposes that thin design into a trifold. The Tecno Phantom Ultimate G Fold is just 3.49mm thick when unfolded and 11.49mm when folded. It unfurls to a spacious 9.94-inch main display, making it resemble a thin and light tablet that happens to unfold like a pamphlet. Like most existing foldables, the crease was still noticeable, but not glaringly so.  

While both the Slim 2 and the Phantom Ultimate G Fold are still only concepts, they reflect an existing mobile trend that’s picking up steam. Several phone companies, from Apple to Samsung to Motorola, have debuted thinner handsets in the last year. These are designed to appeal to shoppers who care less about having the biggest batteries or most advanced cameras and more about reducing bulk. 

Foldable phones are also slimming down, including the Samsung Galaxy Z Fold 7, Honor Magic V6 and Oppo Find N5 (and, soon, N6). And two thin trifolds have dominated the conversation for flexing design innovation: the Huawei Mate XTs and the Galaxy Z Trifold.  

If or when Tecno’s latest concoctions will join the thin phone party remains to be seen.
