摘要
This invention provides methods of and related apparatus for driving an electro-optic display having a plurality of pixels to display white text on a black background (“dark mode”) while reducing edge artifacts, ghosting and flashy updates. The present invention reduces the accumulation of edge artifacts by applying a special waveform transition to edge regions according to an algorithm along with methods to manage the DC imbalance introduced by the special transition. Edge artifact clearing may be achieved by identifying specific edge pixels to receive a special transition called an inverted top-off pulse (“iTop Pulse”) and, since the iTop Pulse is DC imbalanced, to subsequently discharge remnant voltage from the display. This invention further provides methods of and related apparatus for driving an electro-optic display having a plurality of pixels to display white text on a black background (“dark mode”) while reducing the appearance of ghosting due to edge artifacts and flashy updates by identifying specific edge pixels to receive a special transition called an inverted Full Pulse transition (“iFull Pulse”).
