Abstract
A color electrophoretic display that includes sets of duplicative waveforms to reduce visible artifacts during image updates. Such methods include driving extra pixels where the boundary between a driven and undriven area would otherwise lead to artifact by providing paired sets of driving instructions, allowing the undriven area to be driven while maintain the desired (undriven) optical state.
