LG Display has introduced an electronic reader that is equipped with solar cells. The reader has been developed so that one side are the solar cell size 10x10cm while the other is the screen diagonal length of 6 "from which users can read books or magazines in electronic format. The current conversion efficiency of solar energy is 9.6%. Exposure to sunlight for a period of four to five hours of battery operation allows the extension of the reader for a day without additional charge. LG Display said to work on increasing the efficiency of solar cells and hope that it will be increased to 14% by 2012.
