摘要： A driving circuit for an electrophoretic display has a plurality of pixels (18) of an electrophoretic material which comprises charged particles (8, 9). The pixels (18) are associated with a respective first electrode (6) and second electrode (5, 5′) which present a drive voltage (VD) to the pixels (18) to at least enable the charged particles (8, 9) to occupy one of two limit positions between the first electrode (6) and the second electrode (5, 5′). The driving circuit comprises an addressing circuit (16, 10) which generates the drive voltage (VD) by applying between the first electrode (6) and the second electrode (5, 5′): (i) an reset pulse (RE) which has an energy content sufficient or larger than required for the charged particles (8, 9) to reach one of the limit positions, and (ii) a shaking pulse (SP1) which at least partially overlaps the reset pulse (RE). The shaking pulse SP1 has, during the reset pulse (RE), at least partially a level with an opposite polarity than a level of the reset pulse (RE). The shaking pulse (SPI) comprises at least one preset pulse (PR) having an energy sufficient to release the charged particles (8, 9) present in one of the limit positions, but insufficient to enable said particles (8, 9) to reach the other one of the limit positions.

摘要： The electrophoretic display panel (1), for displaying a picture, has drive means (100) which are arranged for controlling the potential difference of each picture element (2) to be a sequence of preset potential differences and subsequently to be a picture potential difference for enabling the particles (6) to occupy one of said positions for displaying the picture. Each preset potential difference represents a preset energy and has as a result a change of the position of the particles (6). For the display panel (1) to be able to display a picture of relatively high quality and to have relatively small changes in the appearances of picture elements (2) as a result of the sequences of preset potential differences even when the number of preset potential differences in the sequences is relatively small, the drive mean (100) are further arranged for controlling for each picture element (2) of at least a number of the picture elements (2) the preset energies of the preset potential differences in the sequence to depend on a serial number in the sequence to obtain for each preset potential difference in the sequence a substantially equal magnitude of the change of the position of the particles (6).

摘要： Electrophoretic display units (1) are driven more flexibly by creating sequences of frame periods in which at least two frame periods of the sequence of frame periods have a different frame period duration and by selecting frame periods from a sequence of frame periods for providing driving pulses to the pixels (11). The number of possible gray values is increased, and the gray values can be generated more accurately. During the rest of the frame periods not chosen for driving the pixel (11), this pixel (11) keeps its gray value due to the bi-stable character. A frame period duration of a frame period is adapted by delaying a start of a next frame period. By supplying data-dependent signals having sections with a positive amplitude and with a negative amplitude, the net driving result is the difference between the sections with the positive and negative amplitudes, to further increase the number of possible gray values.
摘要翻译：电泳显示单元（1）通过创建帧周期的序列而被更灵活地驱动，其中帧周期序列的至少两个帧周期具有不同的帧周期持续时间，并且通过从用于提供驱动脉冲的帧周期序列中选择帧周期到像素（11）。可能的灰度值的数量增加，可以更准确地生成灰度值。在未被选择用于驱动像素（11）的帧周期的其余部分期间，该像素（11）由于双稳态特性而保持其灰度值。通过延迟下一帧周期的开始来适配帧周期的帧周期持续时间。通过提供具有正幅度和负幅度的部分的数据相关信号，净驱动结果是具有正和负幅度的部分之间的差异，以进一步增加可能的灰度值的数量。

摘要： An accurate greyscale is obtained with more natural image updates when updating a display (310) in a bi-stable electronic reading device (300,400), such as one using an electrophoretic display, by applying a first shaking pulse (S1) to the display, applying a first portion (R1) of a reset pulse to the display following the first shaking pulse (S1), applying a second shaking pulse (S2) to the display following the first portion (R1), and applying a second portion (R2) of the reset pulse to the display following the second shaking pulse (S2). The first portion may have a standard reset duration, while the second portion has an over-reset duration. A visual shock effect is avoided which would otherwise as applied after the entire reset pulse.

摘要： In a first display mode, only the information in a first sub-area (W1) of the display screen of a bi-stable matrix display (100) has to be updated. In a second display mode, the information in a second sub-area (W2) of the display screen has to be updated. The information in the first sub-area (W1) is displayed using optical states which require first drive voltage waveforms (DV1) having a maximum duration equal to a first image update period (IUPI). The information in the second area (W2) is displayed using optical states which require second drive voltage waveforms (DV2) having a maximum duration equal to a second image update period (IUP2). The optical states allowed to be used during the first mode are selected to obtain a first image update period (IUP1) which is shorter than the second image update period (IUP2). In this manner, the refresh rate off the information in the first area (WI) is higher than the refresh rate in the second area (W2).

摘要： Electrophoretic display units (1) can get a shorter total image update time by generating and supplying at least some of the data independent signals (Sh1, Sh2, S4, Sh5) during the processing of image information (Del). The processing is done to calculate the data-dependent signals (R,Dr). Data-independent signals (Sh1, Sh2, Sh3, Sh4, Sh5) do not depend on this processing, so these signals may be supplied during the processing. The total image update time is formed by the sum of the time required for image processing (Del) and of the subsequent time required to supply the data-dependent signals (R,Dr) to the pixels (11).

摘要： Electrophoretic display units (1) are driven with a reduced amount of power by efficiently clocking a data signal into the data driving circuitry (30) only once and then supplying this data signal subsequently to two or more pixels (11) in two or more different lines. This can be done in case the pixels (11) in a same column require the same data pulse, like a shaking data pulse (Sh1, Sh2) or a reset data pulse (R). As a result, time is saved, which allows frame periods to be shorter. Even more time can be saved and even shorter frame periods are possible when combining the efficient clocking with the parallel driving of groups of lines (70-72).

摘要： A method and system for controlling electrophoretic and other bi-stable displays (310). Coded data (605, 610, 615) for driving the display is stored in memory (320) for different pixel transitions and different temperatures. The coded data includes voltage level and timing information for the different pixel transitions. A portion (705, 710, 715, 720, 725, 730) of the coded data is retrieved by a controller (100) such as an ASIC based on a selected pixel transition, temperature, and update mode. The portion of the coded data, which may include fixed length frame instructions, is decoded to provide decoded data. The decoded data is used to provide voltage waveforms for driving the display.
