LCD Self-powered Display by Motorola

The patent 7,206,044 was granted on April 17th 2007 to Motorola and describes ways to design LCD panels with dual features: display images and create energy.
By association solar cell to LCD panel, Motorola expects to increase run times in future mobile phones, and why not in the future eliminate the need for conventional charging. With this technology, 75% of the light is transmitted to the solar cell, versus 6% with the current LCD panels. In addition, Motorola claims that the technology will be compatible with the forthcoming OLED panel.
On mobile phone, display is the most power-consuming component besides the CPU, and in the future, large LCD or OLED display-enable mobile phones might be the default design while it is today synonyms of short battery lifetime.
