摘要： An electro-optic display having a plurality of pixels is driven from a first image to a second image using a first drive scheme, and then from the second image to a third image using a second drive scheme different from the first drive scheme and having at least one impulse differential gray level having an impulse potential different from the corresponding gray level in the first drive scheme. Each pixel which is in an impulse differential gray level in the second image is driven from the second image to the third image using a modified version of the second drive scheme which reduces its impulse differential The subsequent transition from the third image to a fourth image is also conducted using the modified second drive scheme but after a limited number of transitions using the modified second drive scheme, all subsequent transitions are conducted using the unmodified second drive scheme.

摘要： 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.

摘要： A method is provided for driving electro-optic displays, especially bistable displays, to avoid edge effects when driving a limited area of the display. Pixels in an edge elimination region, at least one pixel wide and substantially surrounding the limited area, are driven from their original gray level to an intermediate gray level, and then back to their original gray level.

摘要： Methods for driving electro-optic displays, especially bistable displays, include (a) using two-part waveforms, the first part of which is dependent only upon the initial state of the relevant pixel; (b) measuring the response of each individual pixel and storing for each pixel data indicating which of a set of standard drive schemes are to be used for that pixel; (c) for at least one transition in a drive scheme, applying multiple different waveforms to pixels on a random basis; and (d) when updating a limited area of the display, driving “extra” pixels in an edge elimination region to avoid edge effects.
