摘要： Improved electrophoretic media including a first particle of a first polarity and three particles of the opposite polarity, wherein the first particle and optionally one of the particles of the opposite polarity undergo a diminution of electrophoretic mobility with increased electric field. Such electrophoretic media enable full-color displays with very fast updates between white and black pixels.

摘要： A color electrophoretic display that includes sets of duplicative waveforms to reduce visible artifacts during image updates. Such methods include driving extra pixels where the boundary between a driven and undriven area would otherwise lead to artifact by providing paired sets of driving instructions, allowing the undriven area to be driven while maintain the desired (undriven) optical state.

摘要： A variety of methods for driving electro-optic displays so as to reduce visible artifacts are described. Such methods includes driving an electro-optic display having a plurality of display pixels and controlled by a display controller, the display controller associated with a host for providing operational instructions to the display controller, the method may include updating the display with a first image, updating the display with a second image subsequent to the first image, processing image data associated with the first image and the second image to identify display pixels with edge artifacts and generate image data associated with the identified pixels, storing the image data associated pixels with edge artifacts at a memory location, and initiating a waveform to clear the edge artifacts.

摘要： The performance of an electro-optic display, for example, a bistable electro-optic display, can be improved by modifying the frame rate of a base waveform used to drive a transition between gray states. Such modifications permit fine control of gray levels with reduced artifacts. The described methods additionally require less memory to store all of the waveforms needed to achieve good performance of an electro-optic display over a range of temperatures.

摘要： There are provided display controllers and driving methods related to those described in US Published Patent Application No. 2013/0194250. These include (a) a display controller having an update buffer, means for removing from the update buffer pixels not requiring updating, and means to ensure that pixels having certain special states are not removed from the update buffer; (b) a method of driving a bistable display wherein, in a pixel undergoing a white-to-white transition and lying adjacent another pixel undergoing a visible transition, there is applied to the pixel one or more balanced pulse pairs and at least one top-off pulse; (c) a method of driving a bistable display by overlaying a non-rectangular item over a pre-existing image content and then removing the item, where only pixels in the region of the item perform transitions (including self-transitions); and (d) a method of driving a bistable display in which a proportion of background pixels not undergoing an optical change are subjected to a refresh pulse to correct optical state drift.
