Researchers at MIT have pioneered a new method to create sharper displays, stacking diodes to create vertical, multicoloured pixels.
Each stacked pixel can generate the full commercial range of colours, measuring about four microns wide. The microscopic pixels can be packed to a density of 5,000 pixels per inch.
The researchers claim that the vertical micro-LEDs can create a completely immersive experience, as Jiho Shin, postdoc, MIT research group, commented: “With our vertical micro-LEDs, you could have a completely immersive experience and wouldn’t be able to distinguish virtual from reality.”
The full findings of the research can be found in the Nature journal.
Jeehwan Kim, associate professor of mechanical engineering, MIT, commented: “This is the smallest micro-LED pixel, and the highest pixel density reported in the journals. We show that vertical pixellation is the way to go for higher-resolution displays in a smaller footprint.”
