  • Publication number: 20090251391
    Abstract: A power recycling method and apparatus for driving capacitive display elements are described. The driving process involves charging and discharging the display elements. More particularly, the method effectively reuses some of the energy during the discharging process. Energy in display elements flows back from the panel to a power supply and other optionally to devices like RAM, MCU directly during the discharging process. Diodes between one or more power supplies and the display elements ensure that the discharge paths are disconnected when the voltage of display elements drops below the voltage of the power supply. A resistor path from the display elements to ground or a power supply lower than the display threshold voltage of the display elements guarantees that elements are turned OFF after the discharge process.
