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： The electrophoretic display panel (1), for displaying a picture corresponding to image information, has drive means (100) which are arranged for controlling the potential difference of each picture element (2) to be a reset potential difference having a reset value and a reset duration for enabling particles (6) to substantially occupy one of the extreme positions, and subsequently to be a picture potential difference for enabling the particles (6) to occupy the position corresponding to the image information.

摘要： An electrophoretic display comprises a plurality of pixels (18) with an electrophoretic material (8, 9) which comprises charged particles. A first electrode (6) and second electrode (5, 5′) associated with each one of the pixels (18) presents a drive voltage waveform (VD) across each one of the pixels (18). The charged particles are able to occupy, between the first electrode (6) and the second electrode (5), two limit positions and intermediate positions between the two limit positions which are defined by the drive voltage (VD). An addressing circuit (16, 10)generates the drive voltage waveform (VD) by successively applying between the first electrode (6) and the second electrode (5) during an image update period (IUP): (i) a reset pulse (RE) enabling said particles to substantially occupy one of the extreme positions, and (ii) a drive pulse (Vdr) having a level in accordance with an optical state to be reached by the associated one of the pixels (18). The addressing circuit (16, 10) further generates a first shaking pulse (SP1) comprising at least one preset pulse having an energy sufficient to release particles present in one of the extreme positions, but insufficient to enable said particles to reach the other one of the extreme positions. The first shaking pulse (SP1) occurs during a same first shaking time period (TS1) during each image update periods (IUP), independent on the optical state a pixel (18) should reach. The first shaking time period (TS1) precedes the reset pulse (RE) or occurs in-between the reset pulse (RE) and the drive pulse (Vdr).

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： An image is updated on a bi-stable display (310) such as an electrophoretic display by using cyclic rail-stabilized driving, where an image transition is realized either directly via a single drive pulse (D1), or indirectly via a reset pulse (R) and a drive pulse (D2) of opposite polarity. First shaking pulses (S1) are applied to the bi-stable display, when the at least one image transition is realized indirectly, e.g., during at least a portion of the reset pulse and/or the drive pulse of opposite polarity. Furthermore, second shaking pulses (S2) are applied prior to the single drive pulse, or prior to the reset pulse and the drive pulse of opposite polarity. The shaking pulses in either case may include initial shaking pulses (810, 820) and final shaking pulses (815, 825), which have a reduced energy.

摘要： Respective voltage waveforms (700, 720, 740, 760; 800, 820, 840, 860, 900, 920, 940, 960; 1000, 1020, 1040, 1060) are provided for driving respective portions, e.g., pixels, of a bi-stable display (310) such as an electrophoretic display, to a common final optical state. Each waveform includes a driving pulse (D) for driving the respective display portion from a different initial optical state to substantially the common final optical state. The respective voltage waveforms further include at least one re-addressing pulse (RP, RP1, RP2, RP3), which has substantially the same pulse shape in each of the waveforms. The pulse shape may include pulses of alternating polarity, which have substantially the same energy. The re-addressing pulses adjust the particle configurations of the respective display portions such that each display portion has a uniform brightness decay versus unpowered holding time characteristic (1100, 1110, 1120, 1130).
