UCLA Engineers Create Energy-Generating LCD Screen

An anonymous reader writes "Engineers at UCLA have developed technology that allows gadgets like smartphones and laptops to convert sunlight, ambient light, and their own backlight into energy. Equipping LCD-enhanced devices with so-called polarizing organic photovoltaics will recoup battery loads of lost power, and enable smartphone users to scour Yelp, scan Twitter, and update their Facebook page without fear of draining the charge before a real communication crisis arises."

So to charge my phone I just need to take a picture of something black and display it for an hour? =)

Sure. It won't be as fast as charging it from a power strip that is plugged into itself, but it should do fine when out and about.
