    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： An electro-optic display comprising, in order: a light-transmissive layer of conductive material; a layer of bistable electro-optic medium; a layer of light-shielding material; a plurality of pixel electrodes; a layer of photoconductive material; and one or more light emitters. In one exemplary embodiment, the layer of photoconductive material is adapted to bridge a gap between an address line and at least one of the pixel electrodes when the photoconductive material is in a low impedance state. In another, non-exclusive embodiment, the electro-optic display further comprises a second electrode layer between the layer of photoconductive material and the one or more light emitters and a driver adapted to apply voltage between the light-transmissive layer of conductive material and the second electrode layer.

    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.

    摘要： Methods are described for driving an electro-optic display having a plurality of display pixels. Each of the display pixels is associated with a display transistor. The method includes the following steps in order. A first voltage is applied to a first display transistor associated with a first display pixel of the plurality of display pixels. The first voltage is applied during at least one frame of a driving waveform. A second voltage is applied to the first display transistor associated with the first display pixel. The second voltage has a non-zero amplitude less than the first voltage and is applied during the last frame of the driving waveform. The amplitude of the second voltage is based on a voltage offset value and a sum of remnant voltages each frame of the driving waveform contributes to the first display pixel when the first voltage is applied to the first display transistor.
