Abstract: The light modulator for modulating light has a light modulating element, having a medium with a particle (6) and an optical state depending on the position of the particle (6), and a particle controller (10,11,100) being arranged to enable a movement of the particle (6) to one of the positions for modulating the light. For the light modulator to have a particle (6) which can relatively easily be moved, the particle (6) has a carrier particle (81) which contributes in operation to the ability of the particle (6) to be moved and is substantially non-contributing to the optical state, and an optical particle (86) which has an optical property for contributing to the optical state, is associated with the carrier particle (81), and has a position depending on the position of the carrier particle (81).

Abstract: The electrophoretic display panel (1) for displaying a picture has a pixel (2) having an electrophoretic medium (5) having first and second charged particles (6,7), the first charged particles (6) having a first optical property, the second charged particles (7) having a second optical property different from the first optical property, and an optical state depending on positions of the particles (6,7). 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).

Abstract: 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.
