Idaho-based Rohinni is aiming to reinvent ultrathin LED lighting with its Lightpaper technology, which essentially prints lighting and applies it to almost any surface. Lightpaper mixes ink and tiny LEDs and then prints them on a conductive layer, which is positioned between two other layers and sealed. When current runs through the tiny diodes (about the size of a blood cell), they light up. Rohinni envisions the tech being used for everything from illuminated logos on CE devices to vehicle headlights.
Rohinni is currently working on troubleshooting problem areas, such as how the LEDs are placed when printed (they need to be more evenly distributed on the printed surface for some applications). We should expect to see Lightpaper in action by mid 2015.
“With Lightpaper it’s more of a platform of light that we don’t even know how it’s going to be used,” explained CMO Nick Smoot. “All we know is that we’re trying to unlock the ability to create light.”
“The magical thing about this solution is it’s brighter, it’s thinner, it’s flexible, it’s addressable, and programmable,” he said. “You can address the sections of the diodes, which is a whole other space when you start thinking about solutions of light that you can address sections of.”
“Rohinni isn’t interested in the entrenched TV market,” Fast Company reports. “The company would rather put the technology to use where it can make a big difference soon; everything from illuminating a logo on a mobile phone to providing headlights for a car. A few companies are already working on Lightpaper implementations, but Smoot wouldn’t name any.”
“This has the potential of being truly revolutionary,” commented ETC’s Phil Lelyveld. “Displacing existing light and display technology is just the starting point.”
