摘要：
Provided is a method of driving an electrophoretic display device to display an image; the device is comprised of at least one display layer, including a multiplicity of individual reservoirs (30,31,32) containing a display fluid, between conductive substrates (10,20), at least one of which is transparent, wherein the display fluid comprises at least two sets of particles in a liquid medium, the at least two sets of particles each exhibiting a different color, the method comprising the steps of
charging each of the sets of differently colored particles to have a different charge through application of a charging electric field to the display fluid or the device; and
applying an electric field to selected ones of the multiplicity of reservoirs (30,31,32) to effect movement of one or more of the differently colored sets of particles in the display fluid therein to display a desired color derived from among the sets of differently colored particles.
