Researchers at UCLA have created a twist on traditional LCDs that would allow displays to reclaim wasted photons from the backlight, or even act as a normal solar cell. Normal LCDs rely on an always-on backlight, but because of the way LCDs work, most of that light never escapes. This inherent inefficiency hasn't stopped us from getting bright displays, but the power necessary to make them so is usually what runs down your battery.But what if we could recycle that wasted light? Enter UCLA materials science professor Yang Yang and his team of engineers.
