Amazing Printed Lightpaper Revealed

0

Rohinni is a company which has developed a way “to print lighting and apply it to almost any kind of surface”. So what is this invention really?

The product which is called Lightpaper (perfectly adequate) is produced by mixing ink with very, very small LEDs. The concoction is then applied to a conductive layer by printing. The creation is furthermore packed between two other layers and sealed. So how small is one of the diodes? The answer is, it is as tiny as a red blood cell.

When current runs through the conductive layer the paper is lit. The problem at this stage is that the diodes are randomly spread out on the layer, which causes a starry night effect when the product lights up. Exact placement and distribution of the diodes on the surface is what the company is working on next, but for a lot of applications the product is already good to go.

The company is not just another screen provider for the TV market; it wants to put the technology to use where it can make a real difference soon. The CMO Nick Smooth told Fast Company that the technology could for instance provide illumination of mobile phone logos or apply as headlights for a car.

Rohinni is working with multiple partners right now, with names the CMO does not want to mention at the moment. We’re expecting great things though, especially since the next version coming within a few months raises the bar by providing the feature of addressing and programming clusters of diodes on the surface. In the near future, only creativity sets the limits.

On a second and related note, we want to highlight news broken earlier this week by Kurzweil Artificial Intelligence. An international scientist team have finally developed low-cost printed electronics for medical purpose.

The magic about this breakthrough is that it can be printed on actual paper, available cheaply everywhere in the world. Using silver nanowire ink, the researchers have been able to create ultrathin and ultralight capacitive touch devices. Such a device can respond to touch even when curved, folded and unfolded 15 times and rolled and unrolled 5,000 times.

We cannot wait to see the applications for this invention, which according to the scientists are many. Read more about the technology in this post from Kurtzweil AI
