摘要： The present invention provides a novel design for color electrophoretic displays. In the display, each pixel (200) comprises at least two sub-pixels (210, 220, 230), and each sub pixel is fitted with a color filter (211, 221, 231) and contains an electrophoretic media comprising two particle types (201, 202, 203). The color filters (211, 221, 231) in the sub-pixels of each pixel have essentially non-overlapping absorption bands, and together cover essentially all of the wavelengths over which the display is operative. Furthermore, the absorption bands of the particles in each sub-pixel (210, 220, 230) each cover a portion of the wavelengths that is not covered by the filter (211, 221, 231) in the respective sub-pixel. The wavelength bands typically correspond to different colors. Thereby each wavelength band, or color, can be emitted by more than one sub-pixel in each pixel, resulting in increased brightness. According to one particular embodiment, each pixel comprises three sub-pixels having a cyan, magenta, and yellow absorbing filter, respectively.

摘要： A color electrophoretic display has pixels which each comprise an image volume (IV) and a reservoir volume (RV). Different types of particles (Pf, Pm, Ps; Pa, Pb, Pc) which have different colors and different electrophoretic mobilities are present in each one of the pixels. The particles (Pf, Pm, Ps; Pa, Pb, Pc) which are present in the image volume (IV) determine a visible color of the pixel (10), and the particles (Pf, Pin, Ps; Pa, Pb, Pc) which are present in the reservoir volume (RV) do not contribute to the visible color of the pixel (10). The color electrophoretic display is driven to operate either in: a first mode wherein all the types of particles (Pf, Pin, Ps; Pa, Pb, Pc) contribute to a change of color of at least some of the pixels, or a second mode wherein only a subset of the types of particles (Pf, Pin, Ps; Pa, Pb, Pc) contribute to the change of the color of at least some of the pixels.

摘要： The invention relates to an electro-optical cell (1) comprising a first (2) and a second (3) support member, an electro-optical medium (5) between the support members and an electrode arrangement (11, 12) on the support members such that an electric field can be applied, in the electro-optical medium, perpendicular to the support members, aligned with the support members or at an oblique angle (7) with respect to the support members. The electro-optical cell further comprises layers (14) of material with different dielectric constant between the support members in order to reduce the inhomogeneity of the electric field lines in the electro-optical medium. By having a layer of cholesteric liquid crystals between the support members, the electro-optical cell will function as a colour filter for varying applied fields. By introducing a particle suspension in a medium between the support members, an electro-optical cell is created that can be switched between a transmissive, reflective and partly deflective state.

摘要： An electrochromic display comprises electrochrome pixels (10) which comprise at least a first electrochrome material (EL1) and a second electrochrome material (EL2) between two electrodes (E1, E2). Each of the electrochrome materials (EL1, EL2) has two stable states, in one state at a first voltage across the electrochrome pixel (10) the material is transparent, in the other state at a second voltage across the electrochrome pixel (10) the material absorbs a color and thus is colored. The material changes from the one state to the other state by applying the appropriate one of the first or the second voltage. The amount of change of the absorption of the color depends on the time the appropriate voltage is applied. The first electrochrome material (EL1) changes from a transparent state to a color absorbing state for at least partly absorbing a first color when a pixel voltage (VP) across the electrochrome pixel has the first value (V1). The first electrochrome material (EL1) changes from the color absorbing state to the transparent state when the pixel voltage (VP) has a second value (V2) which has a polarity opposite to the first value (V1). The second electrochrome material (EL2) changes from a transparent state to a color absorbing state for at least partly absorbing a second color different than the first color when the pixel voltage (VP) has a third value (V3) which has an absolute value smaller than an absolute value of the first value (V1). The second electro-chrome material (EL2) changes from the color absorbing state to the transparent state when the pixel voltage (VP) has a fourth value (V4) which has a polarity opposite to the third value (V3). An absolute value of the fourth value (V4) is smaller than an absolute value of the second value (V2).

摘要： An electrophoretic display comprises a pixel (10) which has a pixel volume (PV) comprising a reservoir volume (RV) and an image volume (IV). Different types of particles (Pa, Pb, Pc) which have different colors and different electrophoretic mobility's are present in the pixel volume (PV). An amount of the particles (Pa, Pb, Pc) present in the image volume (IV) determines a visible color of the pixel. Select electrodes (SE1, SE2) generate in the reservoir volume (RV) a select electric field (SF) which separates the different types of particles (Pa, Pb, Pc) in different sub-volumes (SVa, SVb, SVc) in the reservoir volume (RV). Fill electrodes (FE1, FE2) generate a fill electric field (FF) to move the different types of particles (Pa, Pb, Pc) from the different sub-volumes (SVa, SVb, SVc) into the image volume (IV).

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).
