Maybe you’ve heard of light-emitting diodes, the low-energy bulbs becoming ubiquitous in everything from holiday lights to television. Well, what about light-emitting paper?

Scientists at Umea University in Sweden figured out a way to make ordinary paper glow as brightly as a computer display.

Nobel For LED Tech Puts Bulbs In Global Spotlight

Ludvig Edman and his colleagues sprayed a piece of paper with an adhesive, four layers of a solution that glows when it’s electrified and top it all with a sealant.

Next, they ran 11 volts of electricity through the paper and when they did, it lit up like computer screen.

Edman told New Scientist that illuminating paper this way is a cheaper way to light up a small area than by using LEDs or OLEDs, which are still relegated to high-end displays.

It seems like a great little invention for people living off the grid, if you could get your energy from solar power.

Or other applications could include food labels that light up when food spoils.

I also think this innovation gets us one stop closer to an electronic book that looks and feels like an actual, paper books. But with a touch of a sensor, the words on the page switch to another novel.

For me, it would combine the best of both worlds: the weight and smell of a book with the convenience of a Kindle. But I digress.

The scientists reported their result in Advanced Functional Materials.
