Appl. No.:

13/755111

International Classification:

G09G 3/34

US Classification:

345212, 345107

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.

International Classification:

G06F 3/02

US Classification:

345168, 345175

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.
