摘要： An electrophoretic display, in which a driving method is employed whereby a sequence of discrete picture potential differences in the form of a driving waveform is supplied for enabling the charged particles (6) of the display to occupy a position for displaying an image, the position being one of a number of positions between the electrodes (3, 4). The driving waveform consists of a sequence of image update signals including a picture potential difference, the image update signals being separated by dwell times, and the method includes the step of generating one or more shaking pulses during the dwell times. Such shaking pulses may be generated immediately after each image update signal or they may comprise regular shaking pulses generated at predetermined intervals along the waveform.

摘要： Electrophoretic display units (1) are driven with a relatively low amount of power and more efficiently by addressing the pixels (11) only once during a sequence of frame periods. Compared to addressing a pixel (11) each frame period, for signals having a duration of more than one frame period, a large amount of power is saved. During a sequence of frame periods formed by a time-interval (T 1 -T 8 ), one or more reset pulses (R) or one or more driving pulses (Dr) are provided. The addressing of a line of pixels (11) can be skipped during a sequence of frame periods if all pixels (11) of the line of pixels (11) have to remain unchanged. Signals having a duration of two or more frame periods do not need to be supplied to the pixels (11) each frame period, but need to be supplied only once by addressing the pixels (11) only once during a sequence of frame periods.
摘要翻译：电泳显示单元（1）通过在帧周期的序列期间仅对像素（11）进行寻址一次而以相对较低的功率量和更有效地驱动。与每帧周期的像素（11）寻址相比，对于具有多于一个帧周期的持续时间的信号，节省了大量的功率。在由时间间隔（T1-T8）形成的帧周期序列期间，提供一个或多个复位脉冲（R）或一个或多个驱动脉冲（Dr）。如果像素线（11）的所有像素（11）必须保持不变，则可以在帧周期的序列期间跳过像素线（11）的寻址。具有两个或更多个帧周期的持续时间的信号不需要在每个帧周期提供给像素（11），而是需要在帧周期序列期间仅寻址一次像素（11）来提供一次。

摘要： The electrophoretic display unit (1) comprises drivers (60,61) for driving pixels (11) groups (70,71) of lines in parallel during data-independent parts of frame periods. During data-independent parts of frame periods, the groups (70,71) of lines are driven with common data and during data-dependent frame periods, the groups (70,71) of lines are driven with specific data. Preferably, the drivers (60,61) are row drivers, with the groups (70,71) of lines being groups of rows. During data-independent parts of frame periods, especially when shaking pulses are applied, the frame period can be reduced.

摘要： A cyclic rail-stabilized method of driving an electrophoretic display device (1), wherein a substantially dc-balanced driving waveform is used to effect the various required optical transitions. The driving waveform consists of a plurality of picture potential differences (20), which cause the charged particles (6) of the electrophoretic device (1) to cyclically between extreme optical positions in a single optical path, irrespective of the image sequence required to be displayed, i.e. in order to display each grey scale, it is necessary for the particles (6) to first pass through one of the extreme optical states. In order to minimise the effects of dwell time on the image quality and minimise, or even eliminate, the need to consider image history, shaking pulses (10) are generated immediately prior to each picture potential difference (20).

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 (SP1) 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： Image quality is improved when updating a display image (310) in a bi-stable electronic reading device (300, 400) such as one using an electrophoretic display, by providing both monochrome and greyscale images. When an update mode of a pixel (2) of the display changes from a monochrome to greyscale, a compensating pulse (805, 825, 845, 865) is applied. The compensating pulse represents an energy based on the energy difference between: (a) an over-reset pulse (815, 835, 855, 875) used during the greyscale update mode and (b) a standard reset pulse (610, 660) used during the monochrome update mode. Also, a monochrome update waveform (600, 650) includes a standard reset pulse (610, 660) whose duration is substantially less than a duration of an over-reset pulse (815, 835, 855, 875) used in a greyscale update waveform (800, 820, 840 and 860). The monochrome update mode is used in combination with the greyscale update mode when possible.

摘要： An electrophoretic display panel and a method for driving an electrophoretic display panel in which the drive pulse, i.e. the grey scale pulse, to bring an element from a preceding optical state to an optical state is split in more than one sub-pulses. A more gradual introduction of the grey scale is thereby achieved reducing the suddenness of the transition form one image to another. Preferably application of the grey scale potential differences is preceded by application of reset pulses in which case the preceding optical state is an extreme optical state.
