Patent ID: 7463408

Claim:
A color electrophoretic display comprising at least one pixel operative to display visible light in a predetermined range of three or more wavelengths, each pixel comprising at least two sub-pixels which each comprise: a color filter operative to absorb one sub-range of said predetermined range of wavelengths and pass the other wavelengths; an electrophoretic media comprising two types of particles, each type of particle being operative to absorb a second and third sub-range of said predetermined range of wavelengths, respectively; and means for separately controlling the spatial distribution of the respective particles in said electrophoretic media between visible and invisible locations; wherein said fixed sub-ranges of the respective sub-pixels in each pixel are essentially non-overlapping and in combination cover essentially all of said predetermined range of wavelengths; and wherein, in each sub-pixel, said second and third sub-ranges are different from each other, and cover essentially all of said predetermined range of wavelengths only in combination with the fixed sub-range of the related sub-pixel.
