UCLA Researchers Develop Method For LCDs That Recycle Energy

Outside of wireless power, having a display that can actually recycle energy might be the other holy grail of consumer electronics energy. Now, researchers from UCLA have created a new technology that may bring this dream into reality.

The new technology uses photovoltaic polarizers in order to turn ordinary LCDs into ones that could be powered by sunlight and their own backlight. This technology allows the displays to convert ambient light, sunlight and their own backlight into electricity. The energy-harvesting polarizer for LCDs (something called a polarizing organic photovoltaic) can potentially boost the function of an LCD by working simultaneously as a polarizer, a photovoltaic device and an ambient light or sunlight photovoltaic panel.


When looking at the raw energy usage numbers, things are fairly staggering. A device's backlight can consume 80 to 90 percent of the device's power, but as much as 75 percent of the light generated is lost through the polarizers. A polarizing organic photovoltaic LCD could recover much of that unused energy.
 
It's hard to say when this will leave the lab and head to the marketplace, but at least there is some promise that battery life may actually improve in the future, rather than continually getting worse with the advent of things like 4G.

If only it can recover 100% of the energy :) lol But cool method for the future.

This sounds awesome... I can not only imagine what it is going to do for mobile devices. But how about saving energy and going green in a home for TV/Computer screens this type of technology can bring our energy usage down considerably.

Nice so if 80-90% of that light energy is wasted, and the photovoltaic recaptures 65-75% then a display would use less than 25% of the current amount of energy it uses. That would be low; as the current energy star, flat panel/Wide screen, monitor's specifically, and laptop display's as well use a relatively low amount of energy now, and HD TV's would also fall into this mix to.

Thanks for this post. If you're anywhere near Mission Viejo then you have got to go to The Shops at Mission Viejo for your back to school clothes. They, in conjunction with the city and Waste Management are offering a Super Recycler award to retailers. http://youtu.be/UysU018cxCE
