    摘要： A touch screen electro-optic display is arranged such that upon a touch being detected on the display surface, the display surface surrounding the touch "blinks" by being driven to a different optical state, then back to its original state. A second method uses a display having a pen or stylus which can draw lines upon the display. A first line segment is detected and its area updated using a first drive scheme having short waveforms. The area of a second line segment is updated using the first drive scheme. Thereafter, the areas of both line segments are updated using a second drive scheme different from the first drive scheme.

    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”).
