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: Methods for driving electro-optic displays to reduce visible artifacts include (a) applying a first drive scheme to a minor proportion of the display pixels and a second drive scheme to other pixels, the pixels using the first drive scheme varying at each transition; (b) using different drive schemes on different pixel groups so that pixels in differing groups undergoing the same transition use different waveforms; (c) applying a balanced pulse pair or a top-off pulse to a pixel undergoing a white-to-white transition and lying adjacent a pixel undergoing a visible transition; (d) driving extra pixels where the boundary between driven and undriven areas falls along a straight line; and (e) driving a display with both DC balanced and DC imbalanced drive schemes, maintaining an impulse bank value for the DC imbalance and modifying transitions to reduce the impulse bank value.
