Researchers in Los Angeles created a dangerous twist on traditional LCDs that allow monitors to recover wasted a photon of light, or even serve as conventional solar cells. Normal LCDs rely on Backlight always on, but because of the way of LCDs, most of that Light never escapes. This inherent inefficiency has not prevented us from getting bright displays, but you must make them power so usually that passes your battery.
Enter UCLA materials science professor Yang Yang and his team of engineers. Among layers LCD – two polarizing sheets block unwanted backlight depending on their configuration. The team at UCLA has developed a new type of material for these layers is called a polarizing organic photovoltaic film. Instead of just blocking light, it will act as a photovoltaic cell and absorb the energy of light — whether it comes from inside or outside of the device. Essentially it will reuse the light from the light at the same time as the solar panels.
No guarantee against things like battery life and power draw, as they depend on many other factors but Botros Youssry Intel said that it could potentially yield of 75 per cent wasted photons with LCD and turn them back into electricity ". Make your own calculations. Later, he uses the word "synergy", which I think he means a synergistic, but to be honest its version sounds better.
Jan hopes to cooperate with manufacturers to make this major and said that the method is "simple". Still, don't expect your phone to charge themselves using this method any time soon. Research published in advanced materials journal, was conducted with the money from Intel and the Office of Naval Research.
