Rohinni’s Lightpaper

Posted December 1, 2014

Rohinni, Idaho-based company is introducing its Lightpaper, the world’s thinnest LED lighting, according to the company, with an approach where one can apply it to nearly any surface, in any shape and for any situation.


Lightpaper is manufactured by mixing ink and tiny LEDs together and printing them out on a conductive layer. That object is then sandwiched between two other layers and sealed. The tiny diodes are about the size of a red blood cell, and randomly dispersed on the material. When current runs through the diodes, they light up.

The promise of thin lighting is because of breakthroughs in OLED technology. Lightpaper is much thinner than OLED—which has been able to get TVs down to a fraction of an inch thick—and is lower cost and has a life-span of around 20 years, like LEDs.

The technology could be illuminating logos on products, such as mobile phones, installing lighting on your wall, or a wearable wristband flashing the time and message notifications.
