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： Electro-optic displays with reduced remnant voltage, and related apparatus and methods are provided. A remnant voltage of a pixel of an electro-optic display may be discharged by activating the pixel's transistor and setting the voltages of the front and rear electrodes of the pixel to approximately the same voltage for a specified period of time, and/or until the amount of remnant voltage remaining in the pixel is less than a threshold amount. The remnant voltages of substantially all pixels or a subset of pixels in an active matrix electro-optic display may be simultaneously discharged. The simultaneous discharge of the remnant voltages of pixels may take place when the pixels are in a same state, characterized by (1) the transistor of each pixel being active, and (2) the voltages applied to the front and rear electrodes of each pixel being approximately equal.

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： 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.

摘要： This invention provides methods of and related apparatus for driving an electro-optic display having a plurality of pixels to display white text on a black background (“dark mode”) while reducing edge artifacts, ghosting and flashy updates. The present invention reduces the accumulation of edge artifacts by applying a special waveform transition to edge regions according to an algorithm along with methods to manage the DC imbalance introduced by the special transition. Edge artifact clearing may be achieved by identifying specific edge pixels to receive a special transition called an inverted top-off pulse (“iTop Pulse”) and, since the iTop Pulse is DC imbalanced, to subsequently discharge remnant voltage from the display. This invention further provides methods of and related apparatus for driving an electro-optic display having a plurality of pixels to display white text on a black background (“dark mode”) while reducing the appearance of ghosting due to edge artifacts and flashy updates by identifying specific edge pixels to receive a special transition called an inverted Full Pulse transition (“iFull Pulse”).
摘要翻译：本发明提供了用于驱动具有多个像素的电光显示器的方法和相关装置，以在黑色背景（“暗模式”）下显示白色文本，同时减少边缘伪影，重影和闪光更新。本发明通过根据算法对边缘区域施加特殊的波形转换以及管理由特殊转变引入的直流不平衡的方法来减少边缘伪影的积累。可以通过识别特定边缘像素来接收称为反向顶置脉冲（“iTop Pulse”）的特殊转换，并且由于iTop脉冲是直流不平衡的，以便随后从显示器放电剩余电压，可以实现边缘伪影清除。本发明还提供了用于驱动具有多个像素的电光显示器的方法和相关装置，以在黑色背景（“暗模式”）上显示白色文本，同时通过识别边缘伪影和闪光更新来减少由于边缘伪影和闪光更新而引起的重影的出现特定边缘像素接收称为反向全脉冲转换（“iFull脉冲”）的特殊转换。
