Screens are becoming ever more important these days, offering us a window into our digital lives. But the screens we usually use have a problem: they use up far too much power, limiting our devices’ battery lives. Not to mention you can’t even read them outside on a bright day. Halion Displays hopes to change all of that. We base our displays on the idea of inks on paper – there’s usually enough light to read a book or a magazine, and they don’t need a battery to work. By using the light that’s already around you, we can cut down the amount of power your screens use dramatically, saving you and your devices a trip to the outlet.
