Abstract
An electrowetting system including a display device having a plurality of electrowetting elements, including a first electrowetting element and a second electrowetting element, each being configurable in a plurality of different display states; and a display controller for electrical addressing of the plurality of electrowetting elements in order to switch the plurality of electrowetting elements between different display states. The display controller is arranged to address the first electrowetting element twice subsequently, separated by a first addressing interval, and to address the second electrowetting element twice subsequently, separated by a second addressing interval, the second addressing interval being longer than the first addressing interval. The present invention further relates to a display controller, a driver stage and a method of controlling a display device.
