摘要： The electrophoretic display panel (1) for displaying pictures 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 enabling the particles (6) to occupy one of the positions for displaying one of the pictures, subsequently to be an inter-picture potential difference having an inter-picture value and an associated inter-picture duration representing an inter-picture energy and subsequently to be a subsequent picture potential difference for enabling the particles (6) to occupy one of the positions for displaying a subsequent one of the pictures. For the display panel (1) to be able to subsequently display pictures of at least relatively medium quality and to have a reduced visibility of the inter-picture appearances of the picture elements (2), the drive means (100) are arranged for controlling for each picture element (2) the inter-picture value to have a sign opposite to a sign of the picture value, the inter-picture energy to be insufficient to substantially change the position of the particles (6) and chosen in a range from larger than zero to substantially equal to the picture energy for reducing an undesired charge accumulation in the picture element (2).

A selection of the particular set of drive waveforms (Si) out of the plurality of sets of waveforms (So, . . . , Si) is determined dependent on optical states of adjacent pixels (18) being adjacent to the particular one of the pixels (18) such that the crosstalk between the adjacent pixels (18) and the particular one of the pixels (18) is decreased. Each set of drive waveforms (Si) comprises drive waveforms (Dij) required to obtain optical states of the particular one of the pixels (18) suitable for a particular configuration of the optical states of the adjacent pixels (18). A selection of the particular drive waveform (Dij) from the particular set of drive waveforms (Di) is determined by a desired optical state of the particular one of the pixels (18). A pixel driver (10, 16) supplies the drive waveforms to the pixels (18).

摘要： A technique for driving a bi-stable display (310) such as an electrophoretic display with reduced cross talk, including reduced image retention and dithering ghosting. Drive waveforms are aligned so that, during an image update period, image transitions (500, 600, 700, 800, 900) between substantially similar optical states (e.g., black-to-black) are terminated substantially later than image transitions (520, 620, 720, 920) between substantially different optical states (e.g., black-to-white). Additionally, a drive pulse in the waveforms for the transitions between the similar states compensates for cross talk caused by a drive pulse in the waveforms for the transitions between the different states. The waveforms include at least one extreme drive pulse (ED, ED1, ED2, ED3) and an additional pulse (A) of opposite polarity.

摘要： A cyclic rail-stabilized method of driving an electrophoretic display device (1), wherein a substantially dc-balanced waveform is used to effect various required optical transitions. The driving waveform consists of a sequence of picture potential differences, which cause the charged particles of the electrophoretic display device (1) to move cyclically between extreme optical positions in a single path, irrespective of the image sequence required to be displayed, except in the case where the desired optical transition is from an intermediate position (or grey scale) to the extreme optical position (or rail state) closest to that intermediate position, in which case the optical transition is effected substantially directly by means of a single voltage pulse (20) which is substantially equal in amplitude and duration, but of opposite polarity, to the voltage pulse (30) required to effect an original optical transition from the rail state to that grey scale.

摘要： The present inventions relates to electrophoretic displays that are switchable between a grayscale updating mode (502) and a monochrome updating mode (501). The monochrome updating mode (501) provides for extreme pixel states only (e.g. black and white), whereas the grayscale updating mode (501) provides for intermediate grayscale pixels states as well. According to the present invention, a suitably selected transition signal (504) is applied when switching from the grayscale updating mode (502) to the monochrome updating mode (501). The transition signal (504) involves a drive pulse that serves to reduce the level of remnant DC voltage otherwise occurring in each pixel due to differences in the grayscale updating mode (502) and the monochrome updating mode (501).

摘要： A cyclic rail-stabilized method of driving an electrophoretic display device (1), wherein a substantially dc-balanced driving waveform is used to effect the various required optical transitions. The driving waveform consists of a plurality of picture potential differences (20), which cause the charged particles (6) of the electrophoretic device (1) to cyclically between extreme optical positions in a single optical path, irrespective of the image sequence required to be displayed, i.e. in order to display each grey scale, it is necessary for the particles (6) to first pass through one of the extreme optical states. In order to minimise the effects of dwell time on the image quality and minimise, or even eliminate, the need to consider image history, shaking pulses (10) are generated immediately prior to each picture potential difference (20).

摘要： An accurate greyscale is obtained with more natural image updates when updating a display (310) in a bi-stable electronic reading device (300,400), such as one using an electrophoretic display, by applying a first shaking pulse (S1) to the display, applying a first portion (R1) of a reset pulse to the display following the first shaking pulse (S1), applying a second shaking pulse (S2) to the display following the first portion (R1), and applying a second portion (R2) of the reset pulse to the display following the second shaking pulse (S2). The first portion may have a standard reset duration, while the second portion has an over-reset duration. A visual shock effect is avoided which would otherwise as applied after the entire reset pulse.
