Abstract
In a linked waveform update mode, an impulse-driven, particle-based electrophoretic display may be updated using a first waveform and then automatically up-dated using a second drive scheme when the update using the first waveform finishes. The display may be automatically up-dated using a third drive scheme when the update using the second drive scheme finishes. The automatic updating using a subsequent drive scheme may be interrupted if the desired display states for the region changes after performing the first update. Waveforms may be selected using: (a) the desired display state of a pixel if the desired display state is a valid display state for the specified drive scheme, or (b) a mapped display state of the pixel if the desired display state is an invalid display state for the drive scheme.
