Devices To Charge Themselves Using Their LCD Screens

“Engineers at UCLA have developed technology that allows energy gobbling 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.

Liquid crystal displays make up the majority of the display screen market because they render bright and colorful images and are relatively easy to manufacture.

As popular as they are, LCDs are by no means efficient — as much as 75% of energy is lost in the traditional polarization process and brightening the display drains the majority of the device’s stored electricity.”
