Engineers invent vertical, full-color microscopic LEDs

Now, MIT engineers have developed a new way to make sharper, defect-free displays. Instead of replacing red, green, and blue light-emitting diodes side by side in a horizontal patchwork, the team has invented a way to stack the diodes to create vertical, multicolored pixels.

Each stacked pixel can generate the full commercial range of colors and measures about 4 microns wide. The microscopic pixels, or “micro-LEDs,” can be packed to a density of 5,000 pixels per inch.

“This is the smallest micro-LED pixel, and the highest pixel density reported in the journals,” says Jeehwan Kim, associate professor of mechanical engineering at MIT. “We show that vertical pixellation is the way to go for higher-resolution displays in a smaller footprint.”

This is really exciting for VR actually, as I feel like VR is stuck in a bit of a holding pattern for 'next best display tech' right now.

Yes for sure. Am still wondering why they stopped using Oled display in VR. Maybe burn in or idk.

We really need better tech!

OLED is the new thing in VR along with pancake lenses. Only issue is the screendoor effect that they bring needs to be mitigated with really high resolutions, and the pancake lenses don't entirely eliminate chromatic aberration artifacts so that's where active eye tracking comes into effect.

New old. My hmd odyssey is oled and was discontinued like 2-3 years ago. Havent read about pancake lenses all i know is headset are getting smaller so it a good thing :D. I love my quest 2 because it wireless!

 

If they can combine all this and make something with high res and wireless 😀

It is very exciting for VR, except a lab at MIT is so far outside a FAB that who knows when/if we will see it. I hope we can manufacture high density OLED before these hit the market.

 

This could be game changing for every display; solving the sub-pixel problems that has been plaguing us since the invention of color displays. e.g. Much sharper text for monitors too.

I don't know anything about VR, but this looks pretty interesting. I switched to OLED last summer and boy what a difference over my last VA panel.

Really curious about the color accuracy regarding the stacked LEDs.  My biggest concern being that there would be some form of lensing or color distortion due to the various colors having to be stacked on top of each other.  However, if they can pulls this off and still maintain accuracy, this could definitely lead to some breakthroughs in terms of VR and AR applications.
