ABSTRACT:
A drive system for a display having segment and common lines is provided. The system may include a first charge pump; a first storage capacitor coupled to the first charge pump at a first pumped voltage level; a second charge pump, including an input terminal coupled to the first storage capacitor; and a second storage capacitor coupled to a pump output terminal at the second pumped voltage level. The system may also include a controller coupled to the first and second storage capacitors, coupled to segment and common lines of an associated display; and a control circuit operating a plurality of switching devices to selectively connect the segment output terminal to the first and second storage capacitors to supply charge to the segment output terminal during a first phase and to return charge from the segment output terminal to the second storage capacitor during a second phase.
