Abstract
A method of driving an electrowetting display device that includes a display element having a cavity; a first fluid and a second fluid within the cavity, the first fluid being immiscible with the second fluid; a surface facing the cavity; and a first electrode. The display device includes a control system for applying a voltage to the first electrode to provide a display state in response to a signal level of the voltage, wherein the control system is arranged to configure the signal level throughout a display period such that the second fluid adjoins at least a minimum area of the surface, the minimum area being greater than a zero area. The method includes applying at least one display signal level during the display period, the at least one display signal level configured such that the first fluid and the second fluid adjoin the surface throughout the display period.
