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： The electrophoretic display panel (1), for displaying a picture and a subsequent picture, has drive means (100) which are arranged for controlling the potential difference of each picture element (2) to be a picture potential difference having a picture value and an associated picture duration representing a picture energy for bringing the particles (6) from one of the extreme positions into one of the positions for displaying the picture, and subsequently to be an inter-picture potential difference for bringing the particles (6) into one of the extreme positions which is closest to the position of the particles (6) for displaying the subsequent picture, and subsequently to be a subsequent picture potential difference for bringing the particles (6) into one of the positions for displaying the subsequent picture. For the display panel (1) to be able to have inter-picture appearances which are at the largest relatively medium visible and in which the dependency on the history due to the charging of the insulators as a result of the picture potential difference is substantially reduced in the subsequent picture update, the drive means (100) are further arranged for controlling for each picture element (2) the inter-picture potential difference to comprise a pull-back potential difference having a pull-back value and an associated pull-back duration representing a pull-back energy, the pull-back value having a sign opposite to a sign of the picture value and the pull-back energy being substantially equal to the picture energy.

摘要： A display device comprises electrophoretic particles, a display element comprising a pixel electrode and a counter electrode between which a portion of the electrophoretic particles are present and a controller for supplying a drive signal to the electrodes to bring the display element in a predetermined black or white state, corresponding to the image information to be displayed. In order to improve the refresh time of the display, the controller is further arranged for supplying a preset signal preceding the drive signal comprising a preset pulse having an energy sufficient to release the electrophoretic particles at a first position near one of the two electrodes corresponding to a black state, but too low to enable the particles to reach a second position near the other electrode corresponding to a white state. The duration of the preset pulses is less than 19 msec, preferably between 1 and 10 msec. Setting the duration of the preset pulses to less than 19 msec reduced visible flicker F.

摘要： The display device comprises a driver (10, 16) which supplies drive pulses to the pixels (18) to bring the pixels (18) in a predetermined optical state corresponding to image information to be displayed. A controller (15) controls the driver (10, 16) to successively supply a drive pulse (Vni) and a correction pulse (dni). The drive pulse (Vni) has a voltage level that is sufficiently high to bring the electrophoretic particles (8, 9) into a continuously moving state as long as the drive pulse (Vni) is present. Due to the history of the drive of the pixel (18) the desired optical state will usually be reached approximately only. The correction pulse (dni) has a voltage level which is too low for bringing the electrophoretic particles (8, 9) into a continuously moving state, as the drive pulse (Vni) does, but high enough for moving the electrophoretic particles (8, 9) over a relatively small distance with respect to dimensions of the pixels (18). Thus, the correction pulse (dni) causes a relatively small movement of the electrophoretic particles (8, 9) towards an equilibrium state.
摘要翻译：显示装置包括驱动器（10,16），驱动器（10,16）向像素（18）提供驱动脉冲以使像素（18）处于与要显示的图像信息相对应的预定光学状态。控制器（15）控制驱动器（10,16）连续提供驱动脉冲（Vni）和校正脉冲（dni）。只要驱动脉冲（Vni）存在，驱动脉冲（Vni）具有足够高的电压电平以使电泳粒子（8,9）进入连续移动状态。由于像素（18）的驱动历史，通常只能达到期望的光学状态。校正脉冲（dni）的电压水平对于使电泳粒子（8,9）处于连续移动状态来说太低，如驱动脉冲（Vni）所示，但足够高以使电泳粒子（8，相对于像素（18）的尺寸相对较小的距离。因此，校正脉冲（dni）使得电泳粒子（8,9）的移动相对较小地朝向平衡状态。

摘要： A display apparatus (1) comprises a matrix display device (DD) with pixels (10) wherein particles (14) move in a fluid (13) between electrodes (6, 6', 7). An optical state of the pixels (10) is defined by a value of a drive voltage (VDi) and a duration (Di) of a drive period (TDi) during which the drive voltage (VDi) is present across the pixel (10). A DC-balancing circuit (3) controls the amplitudes of the drive voltages (VDi) and/or durations (Di) of drive periods (TDi) to obtain a substantially zero time-average value (N) across each pixel (10) or across each sub-group of pixels. This control of the amplitude of the drive voltages (VDi) and/or the duration (Di) of the drive periods (TDi) allows minimizing the image retention, without requiring reset pulses causing all pixels (10) to become temporarily white or black. In a preferred embodiment in accordance with the invention, a display device (DD) is used in which a drive voltage (VDi) is supplied to the pixel (10) with a level such that the grey level (or the amount of colorization) does not change anymore after an initial period of time. Now, if applicable, the DC-balancing can be performed by making the duration (Di) of the drive periods (TDi) longer than the initial period of time.
