Respective voltage waveforms (700, 720, 740, 760;800, 820, 840, 860, 900, 920, 940, 960; 1000, 1020, 1040, 1060) are provided for driving respective portions, e.g., pixels, of a bi- stable display (310) such as an electrophoretic display, to a common final optical state. Each waveform includes a driving pulse (D) for driving the respective display portion from a different initial optical state to substantially the common final optical state. The respective voltage waveforms further include at least one re-addressing pulse (RP, RP1, RP2, RP3), which has substantially the same pulse shape in each of the waveforms. The pulse shape may include pulses of alternating polarity, which have substantially the same energy. The re-addressing pulses adjust the particle configurations of the respective display portions such that each display portion has a uniform brightness decay versus unpowered holding time characteristic (1100, 1110, 1120, 1130).
