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.

Trump Maintains US‑Iran Negotiations Continue Amid Tehran’s Denials of Duplicity
President Trump insists that US‑Iran talks are ongoing despite Tehran’s denial of any negotiation plans, while warning that only a deal or total surrender will allow passage through the Strait of Hormuz. Conflicting statements from both sides have heightened uncertainty as the conflict enters its sixth month.
On Monday, President Donald Trump asserted that negotiations between the United States and Iran are still taking place, even after Tehran stated it has no intention of engaging in direct talks with Washington.
In a fiery Truth Social post, Trump labeled Iran’s leaders “unbelievably duplicitous,” claiming they are lying about ongoing peace talks “whether Iran wants to admit it or not.” He repeated his assertion that the United States completely controls the Strait of Hormuz, despite maritime traffic through the crucial route lingering at only a small fraction of pre‑conflict levels.
He wrote, “Nothing reaches Iran unless we allow it, and nothing will pass unless a deal—or total surrender—is achieved.”
Earlier that day, Iranian Foreign Ministry spokesperson Esmail Baghaei told reporters there is no imminent plan for U.S.–Iran negotiations, contradicting Trump’s earlier comment that talks would resume Monday afternoon. Baghaei added that Iran’s only current discussions are with Oman concerning the Strait of Hormuz.
The conflicting statements have heightened uncertainty over the peace‑talk process and the broader conflict, now in its sixth month.
Trump’s assertion about new negotiations came a day after he said on Truth Social that he had agreed to cancel a massive strike against Iran “subject to being able to rapidly make a DEAL.” He said in the same post that Iran and other Middle Eastern countries had asked him to hold off on that attack because “the perimeters of a deal has been agreed to.”
Trump has claimed dozens of times throughout the more‑than‑five‑month‑long war that a deal is at hand. No permanent deal has been signed, and a temporary ceasefire reached in June has fallen apart.
Trump has also repeatedly threatened to launch devastating strikes against Iran before backing off. After the latest example, oil prices on Monday fell and stocks surged.
BMI, a research unit of Fitch Solutions, said in a note Monday that a broader diplomatic understanding on reopening the Strait of Hormuz is still achievable this quarter, while raising the probability of its escalation scenario to 35% from 25%, citing mounting military, diplomatic and economic signs of rising U.S.-Iran tensions.
“Diplomatic progress is likely to be punctuated by periodic military flare-ups, while miscalculation by either side could trigger a renewed escalation,” BMI analysts wrote in a note. The firm said the key issue to watch is the future governance of the strait, as the Iran-Oman talks — potentially backed by Gulf states, China and the U.S. — point to efforts to build a post-conflict shipping framework.
Shipping risks persist even as diplomacy appears to be advancing. The United Kingdom Maritime Trade Operations Centre said it received a report of an incident 20 nautical miles (23 miles) northeast of Khasab, Oman — at the mouth of the strait — with a tanker’s master reporting an explosion in close proximity to the vessel at about 20:37 UTC Sunday (4:37 pm ET). The vessel and crew were safe and authorities are investigating, UKMTO said, advising ships to transit with caution.
The proposal Trump announced over the weekend calls for the U.S. and Iran to return to negotiations and continue ironing out some of the thorny issues that had derailed diplomatic efforts, according to The Associated Press, citing a regional official involved in the mediation efforts.
The official said the proposal also includes a reopening of the Hormuz Strait and halting attacks across the region, including by Iranian-backed militias in Iraq on the Arab Gulf countries and Jordan.
The U.S., for its part, will end its naval blockade on Iran and allow Tehran to export its oil, the official said, adding that no deal has been reached, although the mediation efforts remained underway.
Trump’s weekend reversal has lowered the temperature after days of escalating attacks across the Gulf. Kuwait said Saturday that Iranian forces launched a wave of drones within its airspace, with its military destroying multiple aircraft after Iran targeted critical infrastructure in the country’s north.
A parallel track with Muscat is also advancing. Iranian diplomats said Tehran was close to reaching a new arrangement with Oman to manage shipping through the Strait of Hormuz, a deal critical to preventing the war from escalating further, according to the Financial Times.
Iranian officials said negotiations over future management of the Hormuz Strait with Oman, which sits on the opposite shore of the waterway, are in their final stages. The agreed shipping route would be different from those used before, according to Iran’s Foreign Ministry spokesperson, Baghaei, adding that the new route was separate from the issue of the strait’s reopening or continued closure.

Oil Prices Slide as Trump Halts Planned Iran Strike
Oil prices dropped after Trump cancelled a planned strike on Iran, with WTI down about 5% and Brent near 5% lower. He said the move followed requests from Tehran and regional allies for a pause while a deal shaping the Strait of Hormuz and Iran’s nuclear program is negotiated.
Oil prices fell on Monday after President Donald Trump announced he had cancelled a planned strike on Iran. WTI futures dropped roughly 5% to $80.34 a barrel, while Brent slipped about 4.7% to $83.77 a barrel.
Trump said early Sunday he called off the strike after Iran and several Middle Eastern nations asked him to hold off, noting that the outlines of a deal had been agreed upon. He added that the prospective accord would entail the immediate, full opening of the Strait of Hormuz and an end to Iran’s nuclear ambitions, according to his Truth Social post.
The president had been considering another round of strikes as diplomatic hopes waned since the conflict began on February 28. He said the U.S. and Iran would meet for talks on Monday, but Iran denied any scheduled negotiations with Washington, citing PressTV. Iran’s foreign‑ministry spokesperson Esmaeil Baghaei clarified that Tehran was only discussing shipping routes through the Strait of Hormuz with Oman. In a follow‑up Truth Social message, Trump insisted that, regardless of Iran’s acknowledgment, the United States is indeed discussing a solution to a long‑standing problem created by Iran.

Oil Prices Drop as Trump Cancels Planned Attack on Iran
Oil prices fell sharply after President Trump announced the cancellation of a planned strike on Iran, citing a new deal that would open the Hormuz Strait and end Iran’s nuclear threat.
Oil prices fell sharply on Monday after President Donald Trump announced that he had called off a planned strike on Iran.
West Texas Intermediate futures, the U.S. benchmark, slipped roughly 5% to close at $80.34 per barrel, while Brent crude, the international benchmark, declined 4.7% to settle at $83.77 a barrel.
Trump made the announcement early Sunday, saying he had canceled the strike following requests from Tehran and other Middle Eastern countries.
In a Truth Social post, he wrote: “We have just been asked by Iran, and other Middle Eastern Countries, to hold off any attack in that the perimeters of a deal has been agreed to.”
The president indicated that the proposed agreement would include the immediate, complete, and total opening of the Hormuz Strait, as well as an end to Iran’s nuclear threat.
Trump had been weighing additional strikes amid diminishing prospects for a diplomatic resolution to the conflict that began on Feb. 28. He stated that the U.S. and Iran would hold negotiations on Monday.
Tehran denied that talks were planned with Washington, according to state news outlet PressTV.
Iran’s Foreign Ministry spokesman Esmaeil Baghaei said Tehran was only holding talks with Oman regarding the routes ships can use through the Strait of Hormuz.
In a subsequent Truth Social post, Trump added that whether “Iran wants to admit it or not, we are, in fact, talking of a solution to a problem that they have caused for decades.”
