Recent advances in microLED technology could significantly improve AR glasses and VR headsets in the future, according to some new research from MIT.
The report claims that vertical stacking could allow for microscopic pixels that provide full color in just 4 microns.
Head-mounted displays have, so far, relied on the same type of screens found in smartphones, tablets, and laptops. But these stacked microLEDs could challenges the way VR headsets are built in the future — and greatly expand their visuals.
Stacked microLEDs can increase resolution compared to the current method of placing red, green, and blue sub-pixels side by side to create each full-color pixel.
The resulting microLED display could theoretically have a resolution of 5,000 pixels per inch (PPI). That’s about 10 times the pixel density of your smartphone. While this resolution would serve no purpose on a screen held at arm’s length, it should greatly improve the quality of displays that are about an inch from your eye. VR displays can suffer from the screen door effect where the pixel grid pattern is apparent.
MicroLED displays also enjoy higher efficiency and improved contrast compared to LCD panels that require backlighting. Even mini-LED backlighting can’t compare since the light source is about one hundred times larger. That’s why you can sometimes see blooming around high-contrast areas in a mini-LED display.
The only competing technology that might be able to match the contrast and density is full-color microLED; however, OLED degrades much more rapidly over time.
MIT researchers are making good progress on vertically stacked microLED displays, having demonstrated a working stacked pixel. They’ve also designed a manufacturing process that reduces waste despite the challenges of working at such a small scale. The next hurdle is to develop a system that can individually control a vast array of these full-color microLEDs.
The transition from the lab to manufacturing is almost impossible to predict, but this is undoubtedly good news for the future of AR glasses and VR headsets.
Google just dropped its latest AI model, Gemini 4 Carbon, designed to tackle complex coding jobs and cybersecurity threats. The company claims it can work through difficult engineering problems for days, finding hidden bugs and developing fixes across large codebases.
Gemini 4 Carbon also takes the top spot on Artificial Analysis' updated Intelligence Index, scoring 59 points, pushing out Claude Opus 5.5, OpenAI's GPT-6 Astra, and even its own predecessor Gemini 4 Argon.
Apple has just introduced a redesigned MacBook Pro with a few bells and whistles. The focus this time around is on a thinner and lighter build, and an upgrade to a touch-sensitive OLED screen without any ugly notch. And, in case you were wondering, there is definitely a price premium to pay for these niceties, which also include a glowing Apple logo at the back. What if you wanted to get the best that Apple has to offer? Well, the numbers are finally here.
For a mere $14,549, you can get yourself the fully kitted 16-inch MacBook Pro PROLED XDR with the beefiest laptop chip that Apple has to offer, and the best memory configuration in tow. For nearly $15,000, you treat yourself to the 16-inch version of the laptop with a nano-texture glass layer on the screen to reduce reflections and glare.
Apple has unveiled its first-ever touchscreen MacBook Pro. The company seems a bit confused about the naming, calling it the "MacBook Pro with PROLED XDR Display," which is tough to remember. If you look past that and review the full spec sheets, you might ask a genuine question: what are the differences between the touchscreen and non-touchscreen versions?
Given that Apple continues to sell both variants together, that's a genuine question. Luckily, you don't have to spend more time lining up the spec sheets side by side and hunting for differences hidden in the fine print. I took that bullet for you. Here's everything that's different between the PROLED XDR Display and the regular MacBook Pro.
