<p>PROBLEM TO BE SOLVED: To provide methods for driving electrophoretic displays, particularly, bistable electrophoretic displays, and apparatus for use in such methods.SOLUTION: A bistable electro-optic display which has at least one pixel is driven using a waveform (figure 1) V(t) characterized in that the integral of the product of the waveform V(t) and M(t) (which is a memory function that characterizes the reduction in efficacy of the remnant voltage to induce dwell-time-dependence arising from a short pulse at time zero) over the length of the waveform V(t) is less than about 1 volt sec. The waveform may comprise a first pulse having a voltage, polarity and duration, and a second pulse having substantially the same voltage magnitude, polarity opposite to that of the first pulse, and duration substantially less than that of the first pulse.</p> |
