Eye Contact Lens with LCD HUD

You may not be ready to be a Cyborg yet, but the technology has already made you one. We can’t live without the smart devices and soon these machines would be part of us.

We’ve seen how Mind-controlled Bionic Leg has proved that Cyborg are not just near, they have already arrived.

By-product of a latest research has brought an actual LCD screen to the Contact Lenses. What that means is that all those SciFi movies that showed retina-based displays right on the eyes are coming to life. For now, these Contact Lens LCDs are monochrome, but in the near future, we can expect it to get better.

“Normally, flexible displays using liquid crystal cells are not designed to be formed into a new shape, especially not a spherical one. Thus, the main challenge was to create a very thin, spherically curved substrate with active layers that could withstand the extreme molding processes,” said Jelle De Smet, the main researcher on the project. “Moreover, since we had to use very thin polymer films, their influence on the smoothness of the display had to be studied in detail. By using new kinds of conductive polymers and integrating them into a smooth spherical cell, we were able to fabricate a new LCD-based contact lens display.”

The research comes from development done at the Centre of Microsystems Technology at Ghent University. Its first lens with an embedded, spherical curved LCD. The point to be noted here is that its a full-fledged LCD which is not shy of the pixels and hence it can can display full fledged graphics. As of now, the screen was demoed to show simple numbers and patterns. What appears on the lens wouldn’t be visible to the person who wear it thats coz eyes cannot focus to such a small distance of the order of millimeters.

But hope is not lost, researchers are trying hard to overcome the minimum distance focus issue and they are not really far from achieveing it, the secret lies int he fact that eyes can be tricked by LCD to have a projection that appears farther than it is. Such an invention would makethis a perfect Headsup-Display (HUD).

While it may appear that its all fancy stuff, their are lots of practical applications of such LCDs. They can be used for medical purposes, such as controlling light transmission to the retina when the iris is damaged, cosmetic uses.

We just have to wait for few more years for this technology to hit mainstreams. For now, delight your senses with this video:
