Abstract
A method for creating waveforms having a multi-transition structure for driving color electrophoretic displays is described. The method includes generating a set of seed candidate waveforms, and applying each seed candidate waveform to the display pixels of the color electrophoretic display. The method includes measuring the optical state of each color created at the display pixels by applying the seed candidate waveforms, and selecting a set of seed waveforms based on the optical measurements of the colors produced by applying each seed candidate waveform. The method also includes generating a first sequence of perturbation waveforms, and applying each perturbation waveform of the first sequence of perturbation waveforms to each seed waveform of the color electrophoretic display. The method also includes measuring the optical state of each color created at the display pixels by applying each perturbation waveform of the first sequence to each seed waveform.
