| abstract |
The electrophoretic medium is composed of a fluid, a second (2), a third (3), a second, a third, and a third, with first, light scattering particles 1 (typically white) and three subtractive primary colors (typically magenta, cyan, And fourth (4) particles; At least two of these colored particles 2 to 4 are non-light scattering. The first (1) and second (2) particles are formed such that the electric field required to separate aggregates formed by the third (3) and fourth (4) particles is formed from any other two types of particles And greater than the electric field required to separate the agglomerates. Methods of driving a medium to produce white, black, magenta, cyan, yellow, red, green and blue colors are also described. |
