My understanding is that there's a great deal of R&D behind optimal waveforms for e-paper. It takes careful tuning to avoid visual artifacts like ghosts and afterimages. And much of the progress in visual quality and longevity over the last several years is from better waveforms. So it's not very fact-like in the sense that anyone could derive the same waveform from theory.
