    摘要: 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.

    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: 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.
