Electophoretic display units ( 1 ) are driven with a relatively low amount of power and more efficiently by addressing the pixels ( 11 ) only once during a sequence of frame periods. Compared to addressing a pixel ( 11 ) each frame period, for signals having a duration of more than one frame period, a large amount of power is saved. During a sequence of frame periods formed by a time-interval (T<SUB>1</SUB>-T<SUB>8</SUB>), one or more reset pulses (R) or one or more driving pulses (Dr) are provided. The addressing of a line of pixels ( 11 ) can be skipped during a sequence of frame periods if all pixels ( 11 ) of the line of pixels ( 11 ) have to remain unchanged. Signals having a duration of two or more frame periods do not need to be supplied to the pixels ( 11 ) each frame period, but need to be supplied only once by addressing the pixels ( 11 ) only once during a sequence of frame periods.
