    • A display device (1) comprises two or more groups of display elements having electrophoretic particles (8,9), a pixel electrode (5) and a counter electrode (6). Drive signals (50, (V,t)drive, (V,t)reset) are supplied to the electrodes to bring the display elements in a predetermined optical state. The drive signals are preceded by preset signals (53, (V,t)preset) to release the electrophoretic particles but too low in intensity to enable the particles to change the optical state significantly. The preset signals supplied to the groups show differences in phase. This reduces flicker. The preset and drive signals are, in operation, so supplied that the phase of the preset pulse preceding the drive pulse is, in respect of the drive pulse, substantially the same for all groups. The combination of a drive and preceding preset pulse is then for the groups substantially the same, reducing grey level variations.
    • 显示装置(1)包括具有电泳粒子(8,9),像素电极(5)和对电极(6)的两组以上的显示元件组。 将驱动信号(50,(V,t)<驱动,(V,t) )提供给电极,使显示元件处于预定的光学状态。 驱动信号之前是预置信号(53,(V,t)<预设),以释放电泳粒子,但是强度太低,以致颗粒能够显着改变光学状态。 提供给组的预设信号显示相位差异。 这减少了闪烁。 预设和驱动信号在操作中被提供,使得驱动脉冲之前的预设脉冲的相位相对于驱动脉冲对于所有组基本相同。 那么驱动器和之前的预设脉冲的组合对于这些组基本相同,从而减少了灰度级的变化。

    • In a method of driving an electrophoretic display, during an image update period (IUi) wherein the pixels (18) of the display are addressed to refresh an image displayed, a chive waveform (DWi) is supplied (10,16) to an associated one of the pixels (18).

The drive pulse (Di) has a variable voltage level to allow obtaining a desired intermediate optical state of the pixel (18) with a high accuracy. An absolute value of the second voltage level (VDi) of the drive pulse (Di) is smaller than an absolute value of the first voltage level (+VM, −VM) of the first pulse (Ri, Si), to minimize the total image update time.

    • An image is updated on a bi-stable display (310) such as an electrophoretic display in a transition from a current image state to a subsequent image state. A voltage waveform (600, 620, 640, 660; 700, 720, 740, 760) is selected based on the current and subsequent image states, and a previous image state. The bi-stable display (310) is driven from the current image state to the subsequent image state using the selected voltage waveform. For a given transition from the current to the next image state, different waveforms are stored for different previous states, e.g., black, dark grey, light grey and white. The different waveforms may have different drive pulse (DR) or reset pulse (RE1, RE2) energies. In a trial and error optimization process, different waveforms with different reset and/or drive pulse energies are tested for different previous image states to see which waveform yields the smallest greyscale error.
    • 在从当前图像状态到后续图像状态的转变中,在双稳态显示器(310)上更新图像,例如电泳显示器。 基于当前和后续图像状态以及先前的图像状态来选择电压波形(600,620,640,660,700,720,740,760)。 使用所选择的电压波形,双稳态显示器(310)从当前图像状态驱动到后续图像状态。 对于从当前图像状态到下一图像状态的给定转换,存储不同的先前状态的不同波形,例如黑色,深灰色,浅灰色和白色。 不同的波形可能具有不同的驱动脉冲(DR)或复位脉冲(RE 1,RE 2)能量。 在试错误优化过程中,针对不同的先前图像状态测试具有不同复位和/或驱动脉冲能量的不同波形,以查看哪个波形产生最小的灰度误差。
