The invention relates to a method of driving an electrowetting display which includes a plurality of electrowetting elements, the display comprising at least one first fluid and a second fluid immiscible with each other, each of the electrowetting elements comprising at least one surface area. In a first, relatively low voltage, driving state of an electrowetting element the second fluid tends to cover the at least one surface area, and in a second, relatively high voltage, driving state of an electrowetting element the first fluid tends to cover the at least one surface area. The method comprises: providing a voltage booster circuit to generate a voltage signal to be applied across one or more selected ones of the plurality of electrowetting elements; and during driving of the one or more selected elements in the second driving state, selectively switching the voltage booster circuit on and off such that the voltage booster circuit is operative only some of the time and the voltage signal includes a voltage ripple variation. The invention further relates to electrowetting display apparatus adapted to perform the method of the invention. |
