    Abstract: A variety of methods for driving electro-optic displays so as to reduce visible artifacts are described. Such methods include (a) applying a first drive scheme to a non-zero minor proportion of the pixels of the display and a second drive scheme to the remaining pixels, the pixels using the first drive scheme being changed at each transition; (b) using two different drive schemes on different groups of pixels so that pixels in differing groups undergoing the same transition will not experience the same waveform; (c) applying either 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 a driven and undriven area would otherwise fall 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.

    Abstract: 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.

    Abstract translation: 触摸屏电光显示器被布置成使得当在显示表面上检测到触摸时，围绕触摸的显示表面通过被驱动到不同的光学状态“闪烁”，然后回到其原始状态。 第二种方法使用具有可在显示器上画线的笔或触控笔的显示器。 检测第一线段并且使用具有短波形的第一驱动方案更新其区域。 使用第一驱动方案来更新第二线段的区域。 此后，使用与第一驱动方案不同的第二驱动方案来更新两个线段的区域。
