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, RP 1 , RP 2 , RP 3 ), 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 ).
