This invention relates to electrophoretic displays having improved performance. The invention also relates to a method for inducing or enhancing the threshold voltage of an electrophoretic display, which method comprises adding a threshold promoter into an electrophoretic fluid which comprises charged pigment particles or pigment-containing microparticles dispersed in a dielectric solvent or solvent mixture.
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.

A method for preparing microcapsules which comprises:dispersing a hydrophobic oily liquid containing a pre-wall former in a continuous aqueous phase, the aqueous phase containing a chain extender which comprises a water soluble polyfunctional compound capable of reacting with the pre-wall former upon dispersion of the hydrophobic oily liquid in the continuous aqueous phase; andforming capsule walls around the droplets of the hydrophobic oily liquid in the continuous aqueous phase.
摘要:
A process for preparing microcapsules which comprises dispersing a hydrophobic oily liquid in a continuous aqueous phase, the hydrophobic oily liquid containing a pre-wall former and at least one chain extender, the chain extender being a polyhydric compound which is capable of reacting with the pre-wall former at a rate such that the chain extender does not substantially react with the pre-wall former prior to dispersing the hydrophobic oily liquid in the continuous aqueous phase; and forming capsule walls around the droplets of hydrophobic oily liquid in the continuous aqueous phase.
