ABSTRACT:
An electrophoretic display device for generating a colored image has pixels each having a medium (12) that is substantially transparent in the optical spectral range and at least two types of independently controllable electrophoretic particles (31C,31M,31Y). The particle species absorb certain wavelengths whereas they are transparent (and basically non-scattering) for light that is absorbed in other particle species. By moving these particles in/out a visible area of the pixel by generating electric fields color absorption can be controlled at will. As the particles are basically transparent (at least for the colors absorbed in the other particle species), the full pixel area (and volume) can be used for any particle species. This way the maximum brightness can be achieved for any color.
