OLED. The technology provides cheap, flexible, and even transparent displays to our devices -- what more could we ask for? Well, some research types at Cornell University have developed a new version of Organic LED that not only emits light, but can take in solar energy to produce electricity. We're not so hot on all the science speak they're tossing around to make this possible, but it seems like the technology could be quite an exciting development for all sorts of products, from solar windows to self-charging screens. No word on how long it'll take this tech to go commercial, but they're already talking ways to make mass production a breeze, so that's at least a good sign.
