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.Â
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.Â
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 . Â

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.Â
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. Â

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.Â

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.Â
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.

AI researcher says extinction odds exceed 10% as experts urge caution
After Jacob Coxon left Anthropic and criticized both Anthropic and OpenAI, other AI safety researchers voiced similar fears about rapid development and insufficient alignment work. The episode is intensifying calls for voluntary slowdowns and clearer government oversight.
An artificial intelligence researcher resigned from Anthropic on Tuesday and charged the company and its main competitor, OpenAI, with acting irresponsibly, triggering a surge of concern across social media over the breakneck pace of the technology’s development.
Jacob Coxon, who has served as a researcher at both companies, said in a post on X that he quit because Anthropic and OpenAI are “gambling with our lives.” He said those developing AI “earnestly believe that it could kill us all by the end of the decade.”
“Do not underestimate the power of this technology,” Coxon wrote. “These will soon be superhuman systems that can hack anything, revolutionize any field overnight, and acquire real power and resources.”
Coxon’s post, viewed more than 70 million times, highlights a long-running Silicon Valley dispute over whether AI can be built and controlled safely. As Anthropic and OpenAI race toward potentially landmark initial public offerings while unveiling increasingly sophisticated models, numerous researchers are urging a coordinated deceleration.
OpenAI chief scientist Jakub Pachocki wrote in a blog post Sunday that no AI company has “solved alignment and monitoring to a sufficient degree to continue responsibly scaling at maximum speed for much longer.” Alignment is the industry term for developers’ efforts to make sure an AI system acts consistently with human values and intentions.
“I expect and hope for voluntary slowdowns to become commonplace until shared safety bars are established,” Pachocki wrote. “And I believe that international coordination on future AI development needs to become a top priority for governments around the world.”
Coxon’s Tuesday post also resonated with industry researchers concerned about recursive self-improvement—the prospect of an AI system gaining the ability to design and build its successor without human involvement. Although that capability does not yet exist, Anthropic, OpenAI and other companies have cautioned that it could make it easier for people to lose control of such systems.
“Neither company is acting responsibly,” Coxon wrote. “They are racing straight to self-improving superintelligence.”
Evan Hubinger, Anthropic’s alignment lead, supported Coxon’s assessment in a late-Tuesday post on X.
“Jacob is correct here—we really do earnestly believe AI could kill all humans! I personally think it is >10% within the next decade,” Hubinger wrote. “I believe Anthropic is trying its best, but we do not yet have a plan to solve alignment for superintelligence and are not clearly on track to.”
Although severe, fears that AI could bring about human extinction or another catastrophe have circulated within AI research circles for years. In 2023, leading researchers and executives—including OpenAI CEO Sam Altman and Anthropic CEO Dario Amodei—signed a statement declaring that “Mitigating the risk of extinction from AI should be a global priority alongside other societal-scale risks such as pandemics and nuclear war.”
Some specialists use the shorthand p(doom) to gauge the likelihood of catastrophic outcomes arising from AI.
Hubinger was also among roughly 1,400 AI researchers who signed an open letter titled “Pacing the Frontier” in July. It called on the U.S. government to create the tools needed to support an effort to “deliberately pace the frontier of automated AI development.”
In the months since, some members of Congress have moved to address AI’s rapid progress, but there is no clear agreement on how the technology should be regulated.
In July, Rep. Jay Obernolte, R-Calif., and Rep. Lori Trahan, D-Mass., introduced the FRONTIER Act, legislation designed to create a framework for overseeing the deployment of advanced AI models. Earlier this month, Sen. Bernie Sanders, I-Vt., and Rep. Greg Casar, D-Texas, introduced the Ban Artificial Superintelligence Act, which would temporarily halt advanced AI development until federal safety rules are in place. Both proposals have received mixed reactions.
“Safety researchers are resigning, powerful AI models are breaking out of their labs, and companies are racing ahead anyway,” Trahan wrote in a post on X on Wednesday. “It’s past time for Congress to get off the sidelines and do its job.”
Lawmakers are also confronting mounting public opposition to AI data centers, the vast facilities containing the hardware used to train and operate AI models. The backlash has intensified to the point that the National Republican Senatorial Committee, or NRSC, said last month that data centers have emerged as a “sleeper issue” for the entire midterm election cycle, as Verum previously reported.
Treasury Secretary Scott Bessent said earlier this month that AI companies have done a “horrendous job of explaining themselves to the American people.”
“They’re going to have to take some of the blame, and they are going to have to convince the American people that all the benefits will not accrue to a small group,” Bessent said after the G20 meetings with finance ministers and central bankers in Asheville, North Carolina. “That’s what they hear from me.”

“South Park” Rebrands as “South America” in Apparent Jab at Trump’s Geographic Renamings
“South Park” will become “South America” ahead of its 29th season, with creators Trey Parker and Matt Stone framing the change as a nod to Apple, Google and Trump’s recent geographic renaming efforts.
Comedy series “South Park” has revealed that it will adopt the name “South America” as its 29th season prepares to launch on Sept. 16.
Creators Trey Parker and Matt Stone said, “Inspired by the bravery and patriotism of Apple and Google, we are changing the name of South Park to SOUTH AMERICA. We especially want to thank our parent company Paramount — a Skydance Capitulation.”
Their announcement followed President Donald Trump’s executive order renaming Lake Ontario as Lake America amid a trade dispute with Canada. Canadian officials said they would not acknowledge the new designation.
Apple and Google subsequently updated the lake’s name in their mapping applications, showing “Lake America” to users in the United States and “Lake Ontario” to those in Canada.
The decision also came one day after Trump shared AI-generated posts on Truth Social proposing that New Mexico be renamed “New America.”
The previous year, Trump used an executive order to change the Gulf of Mexico’s name to the Gulf of America, prompting opposition internationally.
“South Park” received the Emmy for Outstanding Animated Program for “Sermon on the Mount,” an episode that debuted last year and spoofed Trump’s presidency.
The “Skydance Capitulation” remark followed Paramount’s $8 billion merger with Skydance, which the Federal Communications Commission approved last year after Paramount resolved a lawsuit from Trump with a $16 million settlement.
Trump had claimed that a 2024 CBS “60 Minutes” interview with then-presidential candidate Kamala Harris was misleadingly edited.
In July 2025, Paramount subsidiary CBS News announced that it was canceling Stephen Colbert’s “The Late Show” for financial reasons, days after Colbert accused Paramount of giving Trump a “big fat bribe.” The program’s final episode aired in May.
Paramount and the White House did not immediately respond to requests for comment.

Trump stands by decision to start Iran war as U.S. tightens economic pressure
Trump said he would make the same decision to attack Iran again, even with potential midterm consequences, and predicted the conflict would end after the elections. The U.S. is increasing sanctions and other economic pressure on Iran.
U.S. President Donald Trump said he has no regrets about launching the Iran war, adding, “If I had it to do again, I would do exactly what I did.”
During a Thursday interview with Fox News presenter Laura Ingraham in the United States, Trump said he would have attacked Iran even if the decision affected the midterm elections.
“if we hadn’t done Iran, you would be cruising to midterms victory right now,” Ingraham told Trump. Trump replied, “supposing we were cruising, and all of a sudden Iran has a nuclear weapon. They would use it.”
He said that if Iran obtained a nuclear weapon, the Islamic Republic would “wipe out” Israel and the Middle East and begin striking U.S. cities.
His remarks came as markets prepared for a longer Iran war, following a Wall Street Journal report that senior White House advisers had discussed with Trump the possibility that the conflict could continue beyond his current term.
Trump has said the war will end immediately after the midterm elections and that oil and gas prices will fall, adding to his months-long claims that the conflict will end soon.
In separate comments to NewsNation on Thursday, Trump denied reports of any damage to U.S. assets after Iran said it had hit multiple U.S. fighter aircraft at a base in Jordan.
“No damage. No nothing,” Trump said when asked whether the reports were true.
Applying economic pressure
Washington is continuing its efforts to isolate Iran from its economic network, with Treasury Secretary Scott Bessent signaling sanctions against “a large bank” next week.
“We’re going to do it on Monday because we want to honor the memory of our fallen citizens on 9/11. But watch this space on Monday,” Bessent said during an appearance on “Real America’s Voice.”
Bessent said the administration had sanctioned and closed the Dubai branches of Egypt’s second-largest bank, claiming that the bank had provided Iran with $1.8 billion. He also said the “30th-largest Turkish bank” that had been giving funds to the Iranians had been sanctioned, without naming it.
The U.S. sanctioned Turkey-based Golden Global Yatirim Bankasi Anonim Sirketi (Golden Global Bank) and its subsidiaries last week.
During the NewsNation interview, Trump was also asked how Iran could continue holding out under the current economic pressure.
“I don’t know that they’re gonna be able to hold out,” Trump said. “But it’ll get settled after the elections. Or maybe sooner. But it’ll get settled right after the election.”
Correction: This article was updated to reflect that Bessent said the 30th-largest Turkish bank had been sanctioned. An earlier version misstated the bank’s ranking.
