    摘要: The present invention is directed to a method for improving the performance of an electrophoretic display, which method comprises adding a fluorinated quaternary nitrogen salt in either the internal phase or the continuous phase in a microencapsulation process for the formation of pigment-containing microparticles. One or more of the following materials may be further added to the internal phase or continuous phase in the microencapsulation process: a fluorinated protective colloid, a second charge controlling agent or a second monomer or oligomer.

    摘要: This invention relates to an electrophoretic display having display cells filled with an electrophoretic composition which comprises a bi-modal particle system dispersed in a dielectric solvent or solvent mixture. The display has shown a higher % reflectance or whiteness, a higher contrast ratio, improved threshold characteristics and better bistability.
