An electronic device comprises an array of electro wetting cells, each cell comprising first and second liquids () which are immiscible in each other. An electrode arrangement () is used to control the position of the interface between the first and second liquids, and comprises a first electrode and a second electrode. Each cell comprises a first switching device () for applying a cell drive voltage to the first electrode (), and a second switching device () for simultaneously applying the same cell drive voltage to the second electrode (). The cell circuit can be produced without requiring any additional control lines to those required for a single electrode and associated switching device, but the use of two switching devices enables the ultimate signal applied to each electrode to be different as a result of different capacitive effects. This then enables control over the way the liquid interface moves in response to control voltages.
