Ben Krasnow of Applied Science explains how electrophoretic e-paper displays work and how he modified the driver firmware and waveform lookup tables of a 4.2-inch panel to reach roughly 3Hz partial refresh. It covers the tweakable constants in the refresh process and touches on colored e-ink microcapsules.
Why HN recommends it: Whenever e-ink refresh speed or driving waveforms come up, HN points to this as the clearest hands-on explanation of how these displays work and how to hack them.
