Abstract
The present invention relates to an electrowetting system comprising an electrowetting element, a driver stage for applying a voltage to the element, and a switch connecting the electrowetting element to an output of the driver stage. The element comprises a first fluid and a second, immiscible fluid. The instantaneous position of the fluids is dependent on the voltage applied to the element, the voltage being set when the switch is closed. The voltage on the element is substantially maintained during a holding state longer than 70 ms when the switch is open.
