Abstract
An electrowetting display device includes a control system for changing a configuration of first, second and third fluids by applying a voltage level of a first voltage to a first electrode and by applying a voltage level of a second voltage to a second electrode. The voltage level of the first voltage is selected from a first plurality of voltage levels and the voltage level of the second voltage is selected from a second plurality of voltage levels, the second plurality of voltage levels comprising fewer voltage levels than the first plurality of voltage levels.
