Imagine a mobile phone that you never have to plug in, and always remains charged. A new patent from Motorola will bring that possibiility closer. They have developed a screen that allows more light to pass through it than previous designs. This means that a relatively large, but unobtrisive, solar cell could be placed behind the screen.
Previous designs ave been proposed for this, but the reflective screen in normal LCDs meant that only 6% of light passed through to the solar cell. Motorola claim that their recent innovations can raise this up to 75%. The patent also applies to OLED screens, so it's compatible with these new screens that are becoming common on electrical goods. :: Ministry of Tech
