    • 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.
    • 本发明提供了彩色电泳显示器的新颖设计。 在显示器中,每个像素(200)包括至少两个子像素(210,220,230),并且每个子像素装配有滤色器(211,221,231),并且包含包含两个粒子类型的电泳介质 (201,202,203)。 每个像素的子像素中的滤色器(211,221,231)具有基本上不重叠的吸收带,并且一起覆盖显示器可操作的基本上所有的波长。 此外,每个子像素(210,220,230)中的颗粒的吸收带各自覆盖相应子像素中未被滤光器(211,221,231)覆盖的一部分波长。 波长带通常对应于不同的颜色。 因此,每个波长带或颜色可以由每个像素中的多于一个子像素发射,导致增加的亮度。 根据一个具体实施例,每个像素分别包括具有青色,品红色和黄色吸收滤光器的三个子像素。

    • The light modulator (1) for modulating light has a light modulating element (2) and a controller (100,95). For the light modulator (1) to have a stack of at least two differently addressable media, which light modulator (1) can relatively easy be manufactured, the light modulating element (2) has a first and a second medium, each medium extending in a first direction (22) and having a physical state depending on potentials applied to the first and the second medium, and an optical state depending on the physical states. Furthermore, the controller (100,95) is arranged for bringing the first and the second medium in physical states for modulating the light, the controller (100,95) having a configuration of electrodes (95), the configuration extending in the first direction (22); the first medium, the second medium and the configuration of electrodes (95) forming a stack; the electrodes of the configuration (95) being arranged for applying the potentials to the first and the second medium; and decoupling means arranged for decoupling a change in physical state of the first medium from a change in physical state of the second medium in response to the applied potentials.
