Furthermore, particle movement means (10, 11, 100) are arranged to enable a picture movement of the first and the second particles (6, 7) to their respective position for displaying the picture, and particles movement decoupling means are arranged to provide unequal abilities of the first and the second particles (6, 7) to move for substantially decoupling the picture movement of the first particles (6) from the picture movement of the second particles (7).

摘要： A light output device comprises at least one discrete light source device (4) integrated into the structure of a substrate arrangement (1,2,5) and an electrophoretic switchable light control device (40,42; 50; 60,62; 80,82), comprising a controllable region or regions associated with the at least one light source device (4), the electrophoretic switchable light control device (40,42; 50; 60,62; 80,82) being stacked with the substrate arrangement. The electrophoretic device can be used to alter the light output of the light source array, for example providing focusing and/or redirection. This enables the structure of the light source array to be kept simple. The light source array can essentially function as the backlight for the electrophoretic control device.

摘要： An electrophoretic dispersion with at least two particle species is proposed in which a minimal number (and concentration) of free compounds is present in solution. All chemicals needed to color and stabilize the pigment particles are preferably covalently attached to or within the particles. This enhances the robustness of the system and minimizes the conductivity of the dispersion so that the driving voltage for an electrophoretic display is reduced.

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.
