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 aka OLED on Silicon

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.

I Took Google’s New Try On Feature for a Spin — It Was Fascinating (and Hilarious)

Commentary: I used AI to see how different outfits would look on me, and the results were revealing.

Online shopping often feels like a shot in the dark. It’s hard to predict how an outfit a model is wearing will fit me. But at Google I/O on Tuesday, I demoed a new feature called Try On that uses AI to show you how a dress, shirt, skirt or pants will actually look on you. I was surprised, and also incredibly amused.

After posing for a quick photo, a Google employee showed me different clothing options in the Shopping tab. I settled on a cute long-sleeved denim jumpsuit, tapped it and uploaded my photo. After about 30 seconds, my real-life floral jumpsuit was replaced by the denim one. The generated image looked impressively real: the sleeves were perfectly tailored, the collar was popped and my pink headscarf (which I was wearing in real life and Gemini thankfully kept on) was neatly tucked in.

«It actually looks like I’m wearing it,» I said in amazement. «I’m quite impressed.» It even added a purse in my right hand, which was a funny touch.

Try On is powered by Google’s custom image generation model, which can demonstrate how materials drape, fold and stretch on different body types. It’s available now in Search Labs, which lets people try out Google Search features before they roll out to the masses.

After opting into the feature, you’ll see an icon that says «try it on» when browsing for clothes in Google. Upload a full-length photo of yourself (ideally with good lighting and fitted clothing), and watch in wonder as that dress or shirt miraculously appears on you. You can also save the generated image and share it with friends.

Of course, I had to have some fun with Try On. As someone who wears hijab, I only wear long sleeves and long pants when I’m out and about. So I decided to test the feature and see what it would do if I picked a pink sleeveless dress. The result was hilarious.

It did in fact expose my arms (or what it thinks they look like), and also added some random bracelets and a watch that I was definitely not wearing in real life. Thankfully, it kept my headscarf on (which perfectly matched the pink dress), but that only made for a more hilarious juxtaposition with my exposed AI skin. Well, at least it maintained the dress’s accuracy.

If you’re worried about privacy concerns, my colleague Katelyn Chedraoui reached out to Google to ask about Try On’s privacy policies. In response, a Google spokesperson said: «Your uploaded photo is never used beyond trying things on virtually, nor is your photo used for training purposes. It is not shared with other Google products, services or third parties, and you can delete or replace it at any time.»

So, if you’re keen to see how that outfit you would totally wear — or totally wouldn’t — looks on you, look no further than your phone; no fitting room required. Personally, I look forward to trying on more outfits, both appealing and ridiculous, just for the heck of it.

McDonald’s Snack Wrap: Is the Viral Food Favorite Returning on July 14?

July 14 could be the release date for the much-longed-for chicken Snack Wraps, but Ronald and crew aren’t talking.

McDonald’s is riding a viral wave. The fast-food chain’s Minecraft Happy Meals and adult Minecraft Meals hit restaurants on April 1 and sold out quickly. Diners ordering a Happy Meal these days will find a Squishmallow theme meal instead. But there’s more viral buzz about another McDonald’s product online. People are eagerly awaiting the return of Snack Wraps, a chicken-tortilla entree that’s been missing from US locations of the Golden Arches since 2020.

On April 15, McDonald’s tweeted «snack wraps 0x.14.2025,» hinting the wraps would return on the 14th of an upcoming month. This leaves fans having to check their McDonald’s mobile app or local restaurant menus on the 14th of every month, hoping the wraps will make an appearance. The wraps didn’t appear in restaurants on May 14, so now fans must check again in June, and again in July if the June date does not pan out.

At least one Reddit users seems to think the McDonald’s Snack Wraps could return on July 14. One user wrote, «It’s July, I work for McDonald’s,they revealed the date on the employee app.»

But another person posted, «It’s not July. I work at McDonald’s corporate and can confirm.»

Neither of those posts can be confirmed.

June 14 is a Saturday, while July 14 is a Monday. Some suggest that McDonald’s would be more likely to launch a new product on a Monday than on a weekend, so if that’s true, July 14 could be the day.

A representative for McDonald’s did not immediately respond to a request for comment.

Snack Wrap fever

Snack Wraps first came out in 2006, and were meant to be a chicken item that would appeal to drive-thru customers. There are different versions, but the basic one includes white-meat chicken strips known as McCrispy Strips wrapped in a flour tortilla with cheese and lettuce with either ranch, honey mustard or salsa. McCrispy Strips are a reworked version of a chicken item formerly known as Chicken Selects.

Zach Ciampa, who regularly covers new food releases under the social-media handle Snach With Zach, said there’s been an intense fanbase out there for the wraps. «Regarding McDonald’s Snack Wrap, it’s by far the most requested item I’ve ever seen my audience ask or demand to come back,» he told CNET. «Not just the most requested in recent memory, but the most requested of all time. And that’s not limited to McDonald’s.» Ciampa said the only similar fast-food items that come close to the same level of interest are Dairy Queen’s S’mores Blizzard and Taco Bell’s Caramel Apple Empanada, both of which also made recent returns.

«I’ve been covering food releases for years, and in that time, I’ve seen countless comments to the tune of ‘We don’t want this. We want the Snack Wrap,’ and, ‘Can you tell us when the Snack Wrap is coming back?'» he said. «A couple years ago, the chances of its return were pretty bleak. However, things escalated pretty quickly in late 2023 when McDonald’s did indeed announce that the Snack Wrap would return in a new form. Since then, details have slowly but surely trickled out, and the hype has steadily grown.»

While Snack Wraps left McDonald’s locations in the US back in 2020, they remained available at Canadian and UK restaurants. The current online McDonald’s Canada menu includes several tortilla-wrapped items, including ones with crispy chicken, grilled chicken, buffalo chicken and chicken with a sweet chili sauce.
