Abstract

A system and method are disclosed for mitigating the effect of induced reverse bias in a passive matrix electrophoretic display. An intermediate biasing phase is performed prior to the driving cycle, the biasing conditions of the intermediate biasing phase being selected so as to break into at least two steps the transition from the bias condition present prior to the driving cycle to the bias condition applied during the driving cycle. Interposing a settle phase subsequent to the driving phase for each scanned row and prior to the driving phase of the next row to be scanned is disclosed. Adding a pre-drive phase prior to scanning to mitigate the effect of induced reverse bias is disclosed. Adding an inline resistor between a driver and an electrode with which the driver is associated is disclosed. Also disclosed is displaying an image in an electrophoretic display by first driving an array of electrophoretic cells to a white displayed state and then driving background areas to a background display state. In addition, interposing a balance phase after each row is scanned to restore display elements in non-scanning rows to the same initial state is disclosed.
