Abstract
A method of controlling an electrowetting display device with display elements arranged in a matrix with n rows. In examples each display element is addressable with a voltage pulse having a pulse duration longer than Tf/n, where Tf is a pre-determined frame period for addressing the n rows. In examples the pulse duration may be longer than ReCe, with Re being an electrical resistance of an electrically conductive fluid of a display element and Ce being an electrical capacitance of a capacitor of the display element.
