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.

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： An electro-optic display including an array of pixel electrodes, where each row of pixel electrodes is associated with a source line, and that source line is connected to a drive chip with a T-wire that connects from the back of the substrate to the front of the substrate through a via. The vias are spaced out, such as in a zig-zag pattern or a pseudo-random pattern to reduce the capacitive coupling between the T-wires when adjacent pixels are driven, for example when presenting text characters.

摘要： 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.

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.
