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： 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 (IUP1). 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 of the information in the first area (W1) is higher than the refresh rate in the second area (W2).

摘要： The electrophoretic display panel has an electrophoretic medium having charged particles, a plurality of picture elements, electrodes associated with each picture element for receiving a potential difference, and drive means. The drive means are arranged for controlling the potential difference of each of the plurality of picture elements to be a potential difference for enabling the particles to occupy the position corresponding to image information. For the display panel to be able to provide a smoother change-over from one image to another, the drive means are arranged for providing, during a portion of the image transition period, different starting times for application of the potential differences within the duration of the portion of the transition period for potential differences having a duration less than the maximum duration of the portion of the image transition period.

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.

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： 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).
