摘要： A display device (101) has groups of display elements (118), which are changed from one optical state to another optical state by applying a waveform sequence of potential differences. The waveform enables particles (108, 109) to occupy a position corresponding to the other optical state and includes standard reset, over-reset and grayscale drive. The standard reset part of the waveform applies a potential difference, which is proportional to a distance the particles (108, 109) must move to reach one of the extreme optical states and the over-reset is independent of the distance. Grayscale or color scale accuracy is improved and direct charge on a pixel may be balanced over time with consequent grayscale drift compensated by tuning the grayscale driving pulse.

摘要： Electrophoretic display units (100) comprising pixels (11) situated between a common electrode (6) and pixel electrodes (5) need, for shortening the total image update times, increased driving voltages across the pixels (11) which make disturbances more visible. To camouflage such disturbances, instead of one common electrode (6), different counter electrodes (16,17) coupled to different portions (66,67) of the electrophoretic display panel (60) are introduced. First and second counter electrodes (16,17) receive first and second voltage signals (V16, V17) lik˜ alternating voltage signals having opposite phases. First shaking data pulses (V16-VE1, V16-VE3) are supplied to the first portion (66) and second shaking data pulses (V17-VE2, V17-VE4) are supplied to the second portion (67), which first and second shaking data pulses have opposite amplitudes. Setting signals (S1,S2,S3,S4) supplied during setting frame period (FS) reduce voltage swings at pixel electrodes (5).

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 picture potential difference having a picture value and an associated picture duration representing a picture energy for bringing the particles (6) from one 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： 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： 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 preset potential difference having a predetermined duration and subsequently to be a picture potential difference having an actual duration in the range between a smallest duration and a largest duration.

摘要： An electrophoretic display panel (1) for displaying pictures has a first and a second opposed substrate (8,9), an electrophoretic medium (5) between the substrates (8,9), a plurality of pixels (2) and drive means (100). The electrophoretic medium (5) has charged particles (6) in a fluid. The first and the second substrate (8,9) have for each pixel (2) a first and a second electrode (3,4), for receiving a potential difference. The potential difference determines positions of the charged particles (6). The drive means (100) are able to control the potential difference of each pixel (2). The switching time is the time interval to change, in operation, the position of the charged particles (6) between the first and the second electrode (3,4). For the display panel (1) to be able to have a reproducible switching time the display panel (1) further has heating means (13) for heating the medium (5) to a medium temperature in the range of 30° C. and 70° C.

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： A method of driving an electrophoretic display device, in which at least one voltage pulse is provided in the drive waveform, prior to the drive signal for effecting a desired image transition according to an image to be displayed. The voltage pulse has a polarity and energy which is dependent on, and determined by, a current optical state, irrespective of the next optical state to be acquired by a picture element, and causes the charged particles of an electrophoretic medium to be moved in a direction away from the nearest electrode thereto.
