Rohinni’s Lightpaper Is Incredibly Thin, And Printable

In its current state, 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.

It’ll be interesting to see how people use this if the product becomes widely available.
