Holy frak. It’s not every day you hear about something that makes you start dreaming up sci-fi inspired alternative realities and possible futures. GE’s OLED printing machine is one of those things.
The size of a semitrailer, the OLED printer coats an 8-inch wide plastic film with chemicals, then seals them with a layer of metal foil. Apply electric current to the resulting sheet, and it lights up with a blue-white glow.
The sheet can be tacked to a wall, wrapped round a pillar, and the translucent version taped to a window. Unlike every other source of lighting, it doesn’t need a lamp or conventional fixture for these sheets, though they need to be plugged into an outlet.
